1. Field of the Invention
The present invention relates to a mobile terminal capable of sensing a tap applied to a display unit in a deactivated state, and a method of controlling the same.
2. Background of the Invention
Terminals may be generally classified as mobile/portable terminals or stationary terminals. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals. Mobile terminals also have become increasingly more functional.
Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.
In addition, terminals cannot be controlled through simple manipulation when the display unit is deactivated. This is inconvenient for the user and requires the display unit to be activated in order to perform operations.
Therefore, an aspect of the detailed description is to provide a mobile terminal controlled by applying a tap, which hits an object, to a deactivated display unit, and a control method thereof.
Another object of the detailed description is to provide a mobile terminal capable of switching a locked state to a released state by a pattern directly set by a user and displaying an execution screen corresponding to the pattern, and a control method thereof.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, the present invention provides a mobile terminal including a terminal body; a display unit switched from one of an activated state in which lighting is turned on and a deactivated state in which lighting is turned off to the other; and a controller configured to sense a plurality of touch inputs applied to the display unit in a state in which the display unit is deactivated, release, when the sensed touch inputs are matched to a pre-set pattern, a locked state of the terminal, switch the deactivated display unit to an activated state, and selectively display on the activated display unit at least one execution screen based on characteristics of the sensed touch inputs among a plurality of pre-set execution screens.
In another aspect, the present invention provides a method of controlling a mobile terminal including switching a terminal body from one of an activated state in which lighting is turned on and a deactivated state in which lighting is turned off to the other; sensing a plurality of touch inputs applied to the display unit in a state in which the display unit is deactivated; when the sensed touch inputs are matched to a pre-set pattern, releasing a locked state of the terminal and switching the deactivated display unit to an activated state; and selectively displaying at least one execution screen based on characteristics of the sensed touch inputs among a plurality of pre-set execution screens on the activated display unit.

Referring still to
The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like).
Examples of wireless signals transmitted and/or received via the mobile communication module 112 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.
The wireless Internet module 113 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.
Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module 113 may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.
In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 may cooperate with, or function as, the mobile communication module 112.
The short-range communication module 114 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus), and the like. The short-range communication module 114 in general supports wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal 100, or communications between the mobile terminal and a network where another mobile terminal 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.
In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which can exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.
The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal. As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.
The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.
The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.
The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the mobile terminal 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. Further, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof. The user input unit 123 may recognize information sensed by the sensing unit 140, as well as by the aforementioned mechanical input means and touch type input means, as information input from a user. Accordingly, the controller 180 can control an operation of the mobile terminal 100 corresponding to the sensed information.
The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.
The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.
The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this instance, the touch screen (touch sensor) may also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller 180 can process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 can sense which region of the display unit 151 has been touched. Here, the touch controller 180 can be a component separate from the controller 180, the controller 180, and combinations thereof.
In some embodiments, the controller 180 can execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor. Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.
An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented so the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.
The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.
When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.
The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.
The controller 180 can typically control the general operations of the mobile terminal 100. For example, the controller 180 can set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.
The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various embodiments disclosed herein.
The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.
The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.
As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from as an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.
Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.
Referring now to
The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.
The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.
In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.
As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.
The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like. As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed so synthetic resin or metal extends from a side surface to a rear surface.
If desired, the mobile terminal 100 may include a waterproofing unit for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.
The mobile terminal 100 may include the display unit 151, first and second audio output units 152a and 152b, the proximity sensor 141, an illumination sensor 142, a light output unit 154, first and second cameras 121a and 121b, first and second manipulation units 123a and 123b, a microphone 122, an interface unit 160, and the like.
Hereinafter, as illustrated in
However, the components are not limited to the configuration. The components may be excluded, replaced, or disposed on other surfaces as needed. For example, the first manipulation unit 123a may not be provided on the front surface of the terminal body, and the second audio output unit 152b may be provided on the side of the terminal body, rather than on the rear surface of the terminal body.
The display unit 151 may display (or output) information processed in the mobile terminal 100. For example, the display unit 151 may display executed screen information of an application program driven in the mobile terminal 100, or user interface (UI) information or graphic user interface (GUI) information according to the executed screen information.
The display unit 151 may include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, and an e-ink display.
The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.
The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.
The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.
The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see
The first audio output module 152a may be implemented in the form of a receiver and the second audio output unit 152b may be implemented in the form of a loud speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.
The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this instance, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.
The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.
The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.
The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.
As another example of the user input unit 123, a rear input unit may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.
The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. However, the present invention is not limited thereto and a position of the rear input unit may be modified.
When the rear input unit is provided on the rear surface of the terminal body, a new user interface may be implemented. Also, when the touch screen or the rear input unit as described above replaces at least some functions of the first manipulation unit 123a provided on the front surface of the terminal body so the first manipulation unit 123a is omitted from the front surface of the terminal body, the display unit 151 can have a larger screen.
As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.
The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.
The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.
The second camera 121b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a.
The second camera 121b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.
As shown in
At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.
A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.
The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.
An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.
Hereinafter, a communication system which is operable with the display device 100 according to the present invention will be described. A communication system which is operable with the variously described mobile terminals will now be described in more detail. Such a communication system may be configured to utilize any of a variety of different air interfaces and/or physical layers. Examples of such air interfaces utilized by the communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications System (UMTS) (including, Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced)), Global System for Mobile Communications (GSM), and the like.
By way of a non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types including a CDMA wireless communication system as well as OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system.
A CDMA wireless communication system generally includes one or more mobile terminals (MT or User Equipment, UE) 100, one or more base stations (BSs, NodeB, or evolved NodeB), one or more base station controllers (BSCs), and a mobile switching center (MSC). The MSC is configured to interface with a conventional Public Switched Telephone Network (PSTN) and the BSCs. The BSCs are coupled to the base stations via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, the plurality of BSCs can be included in the CDMA wireless communication system.
Each base station may include one or more sectors, each sector having an omni-directional antenna or an antenna pointed in a particular direction radially away from the base station. Alternatively, each sector may include two or more different antennas. Each base station may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz, etc.).
The intersection of sector and frequency assignment may be referred to as a CDMA channel. The base stations may also be referred to as Base Station Transceiver Subsystems (BTSs). In some cases, the term “base station” may be used to refer collectively to a BSC, and one or more base stations. The base stations may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station may be referred to as cell sites.
A broadcasting transmitter (BT) transmits a broadcast signal to the mobile terminals 100 operating within the system. The broadcast receiving module 111 of
Global Positioning System (GPS) satellites for locating the position of the mobile terminal 100, for example, may cooperate with the CDMA wireless communication system. Useful position information may be obtained with greater or fewer satellites than two satellites. It is to be appreciated that other types of position detection technology, (i.e., location technology that may be used in addition to or instead of GPS location technology) may alternatively be implemented. If desired, at least one of the GPS satellites may alternatively or additionally be configured to provide satellite DMB transmissions.
Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.
For a hardware implementation, it may be implemented by using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, and electrical units designed to perform the functions described herein. In some cases, such embodiments may be implemented in the controller 180 itself.
For a software implementation, the embodiments such as procedures or functions described in the present invention may be implemented with separate software modules. Each of the software modules may perform at least one function or operation described in the present invention. Software codes can be implemented by a software application written in any suitable programming language. The software codes may be stored in the memory 160 and executed by the controller 180.
Information processed in the mobile terminal according to an embodiment of the present invention may be displayed using a flexible display. This will be described in detail with reference to the accompanying drawings.
The flexible display of mobile terminal 200 is generally formed as a lightweight, non-fragile display, which still exhibits characteristics of a conventional flat panel display, but is instead fabricated on a flexible substrate which can be deformed as noted previously.
The term e-paper may be used to refer to a display technology employing the characteristic of a general ink, and is different from the conventional flat panel display in view of using reflected light. E-paper is generally understood as changing displayed information using a twist ball or via electrophoresis using a capsule.
When the flexible display unit 251 is not deformed (for example, in a state with an infinite radius of curvature and referred to as a first state), a display region of the flexible display unit 251 includes a generally flat surface. When the flexible display unit 251 is deformed from the first state by an external force (for example, a state with a finite radius of curvature and referred to as a second state), the display region may become a curved surface or a bent surface. As illustrated, information displayed in the second state may be visual information output on the curved surface. The visual information may be realized so a light emission of each unit pixel (sub-pixel) arranged in a matrix configuration is controlled independently. The unit pixel denotes an elementary unit for representing one color.
According to one alternative embodiment, the first state of the flexible display unit 251 may be a curved state (for example, a state of being curved from up to down or from right to left), instead of being in flat state. In this embodiment, when an external force is applied to the flexible display unit 251, the flexible display unit 251 may transition to the second state such that the flexible display unit is deformed into the flat state (or a less curved state) or into a more curved state.
If desired, the flexible display unit 251 may implement a flexible touch screen using a touch sensor in combination with the display. When a touch is received at the flexible touch screen, the controller 180 can execute certain control corresponding to the touch input. In general, the flexible touch screen is configured to sense touch and other input while in both the first and second states.
One option is to configure the mobile terminal 200 to include a deformation sensor which senses the deforming of the flexible display unit 251. The deformation sensor may be included in the sensing unit 140 (please refer to
The deformation sensor may be located in the flexible display unit 251 or the case 201 to sense information related to the deforming of the flexible display unit 251. Examples of such information related to the deforming of the flexible display unit 251 may be a deformed direction, a deformed degree, a deformed position, a deformed amount of time, an acceleration that the deformed flexible display unit 251 is restored, and the like. Other possibilities include most any type of information which can be sensed in response to the curving of the flexible display unit or sensed while the flexible display unit 251 is transitioning into, or existing in, the first and second states.
In some embodiments, controller 180 or other component can change information displayed on the flexible display unit 251, or generate a control signal for controlling a function of the mobile terminal 200, based on the information related to the deforming of the flexible display unit 251.
The mobile terminal 200 is shown having a case 201 for accommodating the flexible display unit 251. The case 201 can be deformable together with the flexible display unit 251, taking into account the characteristics of the flexible display unit 251.
A battery located in the mobile terminal 200 may also be deformable in cooperation with the flexible display unit 261, taking into account the characteristic of the flexible display unit 251. One technique to implement such a battery is to use a stack and folding method of stacking battery cells.
In accordance with still further embodiments, a mobile terminal may be configured as a device which is wearable on a human body. Such devices go beyond the usual technique of a user grasping the mobile terminal using their hand. Examples of the wearable device include a smart watch, a smart glass, a head mounted display (HMD), and the like. Hereinafter, examples of mobile terminals extending to wearable devices will be described.
A typical wearable device can exchange data with (or cooperate with) another mobile terminal 100. In such a device, the wearable device generally has functionality that is less than the cooperating mobile terminal. For instance, the short-range communication module 114 of a mobile terminal 100 may sense or recognize a wearable device that is near-enough to communicate with the mobile terminal.
In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180 can transmit data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114, for example. Hence, a user of the wearable device can use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user can answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.
The main body 301 may include a case having a certain appearance. As illustrated, the case may include a first case 301a and a second case 301b cooperatively defining an inner space for accommodating various electronic components. Other configurations are possible. For instance, a single case may alternatively be implemented, with such a case being configured to define the inner space, thereby implementing a mobile terminal 100 with a uni-body.
The watch-type mobile terminal 100 can perform wireless communication, and an antenna for the wireless communication can be installed in the main body 301. The antenna may extend its function using the case. For example, a case including a conductive material may be electrically connected to the antenna to extend a ground area or a radiation area.
The display unit 351 is shown located at the front side of the main body 301 so that displayed information is viewable to a user. In some embodiments, the display unit 151 includes a touch sensor so that the display unit can function as a touch screen. As illustrated, window 351a is positioned on the first case 301a to form a front surface of the terminal body together with the first case 301a.
The illustrated embodiment includes audio output module 352, a camera 321, a microphone 322, and a user input unit 323 positioned on the main body 301. When the display unit 351 is implemented as a touch screen, additional function keys may be minimized or eliminated. For example, when the touch screen is implemented, the user input unit 323 may be omitted.
The band 302 is commonly worn on the user's wrist and may be made of a flexible material for facilitating wearing of the device. As one example, the band 302 may be made of fur, rubber, silicon, synthetic resin, or the like. The band 302 may also be configured to be detachable from the main body 301. Accordingly, the band 302 may be replaceable with various types of bands according to a user's preference.
In one configuration, the band 302 may be used for extending the performance of the antenna. For example, the band may include therein a ground extending portion electrically connected to the antenna to extend a ground area. The band 302 may include fastener 302a. The fastener 302a may be implemented into a buckle type, a snap-fit hook structure, a Velcro® type, or the like, and include a flexible section or material. The drawing illustrates an example that the fastener 302a is implemented using a buckle.
Operations implemented in the mobile terminal including at least one of the components described above will be described in detail with reference to the accompanying drawings. Although a bar-type terminal will be described for the purposes of description, but the present invention is not limited thereto. Namely, the present invention may also be applied to wearable devices such as clocks, glasses, or the like.
In a mobile terminal according to an embodiment of the present invention, a lock mode may be executed, in which inputting a control command by a user is limited simultaneously when a display unit is deactivated. When the lock mode is executed (or when the mobile terminal is locked), the controller 180 displays a locked screen formed to input a password to activate the display unit.
Also, the mobile terminal includes a sensing unit configured to sense a tap applied to the display unit in a state in which the display unit is deactivated. For example, the sensing unit may be a touch sensor for sensing a touch input formed by a tap.
When a plurality of touch inputs are sensed by the sensing unit, the controller 180 analyzes an operation pattern of the user formed by sequentially connecting touch points of the sensed touch inputs. When the analyzed operation pattern is matched with a pre-set pattern, the controller 180 can release the locked state of the mobile terminal, activate the display unit, and display pre-set screen information on the display unit. For example, the pre-set screen information may be a home screen or an execution screen of the last executed application.
Thus, the user can release the locked state of the mobile terminal through a simple gesture of tapping the display unit. Thus, the user can omit processes of pressing a button, or the like, to turn on the display unit and inputting a password using a virtual keypad.
Hereinafter, a novel user interface for controlling a mobile terminal based on an operation pattern of a user formed by sequentially connecting touch points of touch inputs sensed in a state in which a display unit is deactivated will be described with reference to the accompanying drawings.
Here, a locked state refers to a state in which inputting a control command by a user is limited and a state in which locking is not released until a pre-set password is input by a particular person. In the locked state, when the display unit 151 is activated, a locked screen formed to allow inputting of a password may be displayed.
When the locked screen is displayed, the user can apply a pre-set type touch to screen information for unlocking output to the locked screen in order to release the locked state. For example, the pre-set type touch may be a touch drawing a path from a first point of a region of the display unit 151 to a second point different from the first point. Namely, the pre-set type touch may be a touch drawing a pattern by a movement path of the touch.
When the touch for unlocking is completed, the controller 180 can switch a locked state to a released state and output a home screen to the display unit 151. In other words, as the locked state is switched to the released state, the mobile terminal can enter a mode in which at least a portion of a plurality of applications installed in the mobile terminal is executable.
Meanwhile, in the mobile terminal according to an embodiment of the present invention, the locked state of the mobile terminal is released based on an operation pattern formed by a plurality of touch inputs applied to the display unit when the display unit 151 is deactivated. In more detail, the operation pattern may be defined as a pattern formed by sequentially connecting touch points of the plurality of touch inputs.
As a result, the mobile terminal is immediately unlocked by the plurality of touch inputs applied in the deactivated state, and pre-set screen information is displayed. In other words, the user can unlock the mobile terminal even without having to input a password to the display unit displaying a locked screen. Operations implemented by an embodiment of the present invention will now be described in detail with reference to
In order to switch a locked state to a released state, a password for unlocking needs to be input. Such a password may be set in advance when mobile terminals are released or may be set or edited by users. For example, referring to
The password input window includes at least one virtual keypad, and in more detail, the virtual keypad may be a number keypad. Based on a user input applied to the virtual keypad, the controller 180 can set a password for unlocking. For example, as illustrated in
Meanwhile, the controller 180 sets up (or registers) an operation pattern for switching a locked state to a released state based on the set password. The operation pattern may be formed by a plurality of taps applied to the mobile terminal. In more detail, the operation pattern may be formed by sequentially connecting touch points of touch inputs formed by the taps. For example, an operation pattern forming vertices of an upper case of alphabet “N” may be set up by sequentially connecting touch points formed by applying four taps.
In order to set up the operation pattern, the controller 180 can divided the entire region of the display unit 151 into a plurality of regions and set up an operation pattern of the user using the divided regions. For example, when a set password is “3142”, the controller 180 can divide the display unit 151 based on the greatest number “4” among the input numbers. For example, as illustrated in
The plurality of divided virtual regions may be given identification numbers in order from left to right or from top to bottom (for example, when the display unit 151 is divided into a total of four virtual regions, first to fourth virtual regions are given identification numbers).
No information is displayed on the display unit 151 in a deactivated state, and thus, the plurality of regions correspond to virtual regions. In other words, since lines partitioning the regions or identification numbers respectively denoting the divided regions are virtual, they are not displayed on the display unit 151 in actuality. When the display unit 151 is deactivated, information related to the plurality of regions may not be output, while virtual lines partitioning the virtual regions, numbers respectively denoting the virtual regions, and a circular figure guiding a touch input may be displayed on the drawings for the purposes of description.
Meanwhile, in an embodiment of the present invention, a password is set up by four digits, and accordingly, the entire region of the display unit 151 is not limited to the dividing of the entire region into four virtual regions. Namely, the controller 180 can divided the display unit into a plurality of regions. For example, the controller 180 can bisect the display unit 151 into upper and lower regions or may trisect the display unit 151 into upper, middle, and lower regions according to a set password, and various operation patterns may be set accordingly.
Subsequently, the controller 180 can set sequentially applying first to fourth touch inputs to the third virtual region, the first virtual region, the fourth virtual region, and the second virtual region, as an operation pattern.
Hereinafter, a pattern previously set to release a locked state of the mobile terminal will be referred to as a “knock code.” When a knock code is set up, the controller can execute a locked state and activate or deactivate the display unit 151.
Here, a “deactivated state of the display unit 151” may refer to a state in which lighting provided inside the display unit 151 to illuminate the display unit 151 is in an OFF state. For example, as illustrated in
In contrast, an “activated state of the display unit 151” refers to a state in which lighting provided inside the display unit 151 to illustrate the display unit 151 is in an ON state. When the display unit 151 is activated, different pieces of screen information are displayed on the display unit under the control of the controller 180. In order to activate the display unit 151 in the locked state, the controller 180 can display a locked screen related to input of password information in order to receive password information for releasing the locked state from the user.
Meanwhile, when the display unit 151 is deactivated, a plurality of touch inputs applied to the display unit 151 may be sensed. In this instance, the controller 180 analyzes an operation pattern formed by sequentially connecting the touch points of the sensed touch inputs. When the analyzed operation pattern is identical to a pre-set pattern, the controller 180 executes an unlocking function. The unlocking function refers to a function of releasing the locked state, switching the deactivated state of the display unit to an activated state, and displaying pre-set screen information on the activated display unit 151.
Namely, when the sensed touch inputs on the display unit in the deactivated state are matched to a pre-set pattern (or a “knock code”), the controller 180 releases the locked state and switches the deactivated state of the display unit to an activate state.
Here, the “sensed touch inputs” refers to a plurality of touch inputs sensed on the display unit 151 in the deactivated state. In more detail, the sensed touch inputs refer to a plurality of touch inputs sequentially applied to at least one of the virtual regions of the display unit 151 divided into the virtual regions.
Meanwhile, when the sensed touch inputs include a plurality of touch inputs sequentially applied to at least one of the virtual regions according to a pre-set pattern, the controller 180 determines that the sensed touch inputs are matched to the pre-set pattern. Alternatively, when a configuration formed by sequentially connecting the sensed touch inputs according to applied order is identical to a configuration formed by the pre-set pattern, the controller 180 may determine that the sensed touch inputs are matched to the pre-set pattern. In other words, the controller 180 determines that a knock code has been received.
For example, as illustrated in
In such a case, as illustrated in
Meanwhile, when the mobile terminal is switched to a released state, a first output screen may not necessarily be a home screen. For example, the last screen information output to the display unit 151 before the locked state was executed may be displayed as pre-set screen information.
Further, at least one of positions and sizes of the virtual regions formed on the display unit may be varied based on touch points of the display unit at which a plurality of touch inputs are sensed. In other words, a plurality of touch inputs matched to the pre-set pattern may form knock codes with different sizes. For example, the sensed touch inputs may be matched to the pre-set pattern to form a knock code corresponding to a first size or may be matched to the pre-set pattern to form a knock code corresponding to a second size different from the first size.
According to the driving scheme as described above, when the display unit 151 is deactivated, the user can input a knock code for unlocking to a different position and/or with a different size. For example, the user, with the mobile terminal held in his or her right hand, can apply a knock code with the thumb of his or her right hand. In this instance, a touch input may be applied within a range that the thumb of the user reaches (for example, a right lower end region of the display unit), and only when a pattern having a shape identical to that of a pre-set pattern is formed by the same number of touch inputs, the controller 180 can release the locked state.
Accordingly, the mobile terminal according to an embodiment of the present invention may provide a more intuitional, simpler user interface environment to the user. Also, in the related art, in order to release a locked state, the user has to activate the display unit 151 using a button, or the like, and input a password using a virtual keypad, but in the foregoing embodiment, such shortcomings are solved. Thus, even when the display unit is deactivated, the user can control the mobile terminal according to a novel method of the present invention.
Further, in the mobile terminal according to an embodiment of the present invention, when a locked state is released by a knock code, the controller 180 can execute different functions based on characteristics of touch inputs applied to the display unit 151 in a deactivated state. Accordingly, different execution screens may be displayed on the display unit 151 when the locked state is released.
When the sensed touch inputs are matched to a pre-set pattern and have first characteristics, the controller 180 can release the locked state and display a first execution screen on the display unit 151, and when the sensed touch inputs are matched to the pre-set pattern and have second characteristics different from the first characteristics, the controller 180 releases the locked state and displays a second execution screen different from the first execution screen on the display unit 151.
Namely, the user can release the locked state and simultaneously control the terminal to display different execution screens by using a single knock code. For example, when the user applies a knock code using a finger, a home screen may be displayed, and when the user applies a knock code using a touch pen, a memo function may be executed to display a corresponding execution screen.
The characteristics of the knock code displaying different execution screens may be previously set in the memory 160 or may be added, deleted, and edited by the user. Namely, certain characteristics of the knock code and an execution screen corresponding to the certain characteristics are stored in the memory 160. When a knock code is received by the display unit 151 in a deactivated state, the controller 180 can release a locked state based on the information stored in the memory 160 and display an execution screen corresponding to the characteristics of the received knock code on the display unit 151.
Hereinafter, a method of setting a knock code will be described with reference to
First, a method of setting a knock code as a function of releasing a locked state by applying a plurality of touch inputs to a display unit in a deactivated state will be described. Here, as discussed above, a knock code refers to a pre-set pattern for releasing a locked state. Such a knock code may be stored in the memory 160 when the terminal is released, or may be added, deleted, or edited by a terminal user.
In the mobile terminal according to an embodiment of the present invention, as illustrated in
In addition, a method of releasing a locked state may include a slide scheme based on a touch continuously moving from a first point to a second point, a face recognition scheme, a pattern scheme based on a movement path of a touch, a PIN scheme based on numbers, a scheme of inputting a password including numbers, and the like.
Meanwhile, when a knock code is selected as a method of releasing a locked state as illustrated in
Thereafter, as illustrated in
The controller 180 senses a plurality of touch inputs sequentially applied to at least one region of the virtual regions 510, and sets a knock code based on touch order and at least one touched region. For example, as illustrated in
As illustrated in
Meanwhile, the controller 180 can display at least one of execution screens on the activated display unit 151 based on the characteristics of the knock code. Namely, although one knock code has been set for an unlocking operation, the user may control the mobile terminal to display various execution screens using the single knock code.
Hereinafter, certain characteristics of the knock code and a method of setting an execution screen corresponding to the certain characteristics in the mobile terminal according to an embodiment of the present invention will be described in detail.
In the mobile terminal according to an embodiment of the present invention, a function executed when a locked state is released by a knock code (hereinafter, the function executed when a locked state is released will be referred to as a “shortcut function”) may be set in the mobile terminal. In more detail, the user can select certain characteristics among a plurality of characteristics of the pre-set knock code, and select a shortcut function corresponding to the selected circuit characteristics.
Thus, different control functions can be executed according to characteristics of the knock code, and an execution screen corresponding to an executed control function is displayed. Namely, as a plurality of touch inputs are sensed, a locked state is released and at least one execution screen corresponding to the characteristics of the sensed touch inputs is displayed. The shortcut function may also be referred to as “immediate execution of App with knock code.”
Next,
The user can set characteristics of a knock code (or characteristics of touch inputs) for executing a shortcut function and a function corresponding to the characteristics. In this instance, the characteristics of the knock code may relate to at least one of a position of an area to which a plurality of touch inputs have been applied, a size of the area to which the plurality of touch inputs have been applied, a type of object used to apply the plurality of touch inputs, and the number of touches included a final touch input among the plurality of touch inputs.
First, as illustrated in (a) of
Next, the user can set a function corresponding to the selected characteristics. For example, as illustrated in (c) of
Thereafter, the controller 180 can select at least one selected function as a shortcut function. For example, as illustrated in (d) of
Also, in the mobile terminal according to an embodiment of the present invention, the controller 180 can designate a region to which a knock code is to be input, and set a shortcut function corresponding to the designated region. In more detail, the controller 180 can specify characteristics of a knock code based on at least one of a position and size of the region to which touch inputs are to be applied, and set a shortcut function corresponding to the at least one of the position and the size of the region.
First, the controller 180 specifies a region for setting a shortcut function in the entire region of the display unit 151. For example, the entire region of the display unit 151 may be divided into two or four execution regions as illustrated in (a) of
In addition, at least one execution region for setting a shortcut function may be directly received from the user. For example, when a figure is formed by a touch trace, a region surrounded by the touch trace (or the interior of the figure) may be specified as a region for setting a shortcut function.
In another example, when a region setting mode for setting a shortcut function is executed, the controller 180 can set a plurality of grid cells and the display unit 151 may display the set grid cells. For example, the display unit 151 may display 20 grid cells (4 (width)×5 (length)=20) each having the same size as an initial setting. However, the size and number of the grid cells displayed on the screen are not limited thereto and may be variously modified.
Although a region setting mode is executed and grid cells are set, the display unit 151 may not display the grid cells. Namely, the grid cells may be merely internally set by the controller 180, without being displayed on the screen.
When displaying the grid cells, the display unit 151 may display a plurality of lines demarcating grid cells and display a plurality of nodes at intersections of the lines. The lines and the nodes may be moved based on a touch input, for example, a drag, applied to the display unit 151. Accordingly, a layout of the grid cells may be changed in the region setting mode.
The controller 180 can select at least one of the cells based on a user input to set a shortcut function. A region corresponding to the at least one selected cell may be specified as a region for setting a shortcut function.
Thereafter, the controller 180 sets a function corresponding to the specified region as a shortcut function. For example, as illustrated in (c) of
Accordingly, as illustrated in (d) of
Also, in the mobile terminal according to an embodiment of the present invention, the controller 180 can determine by which object a touch input sensed by the touch sensor has been applied. In more detail, the controller 180 determines a type of object (or a touch tool) which has applied a touch input based on strength of applied touch input, an area of the applied touch input, an amount of change in electric charge, and the like.
Based on the determined object, the controller 180 can set a shortcut function according to the type of object used to apply the knock code. For example, as illustrated in
Further, certain characteristics of the knock code and the function corresponding to the certain characteristics are not limited to the foregoing embodiments and can be variously configured such that one or more embodiments are combined, or the like.
As described above, the shortcut function may be set by the user or may be automatically set when a knock code is set. In more detail, when a knock code is set, the controller 180 can set a shortcut function according to a pre-set scheme in order to provide an optimal user interface. For example, the controller 180 can set a shortcut function such that a memo function is executed when a knock code is applied by a touch pen. According to this driving scheme, a shortcut function appropriate for certain characteristics of the knock code may be automatically set, implementing a novel user interface. Also, since the user may edit the automatically set shortcut function, a user-friendly interface is provided.
Hereinafter, a control method using a plurality of touch inputs applied to a deactivated display unit in the mobile terminal according to an embodiment of the present invention will be described in detail with reference to
First, referring to
Meanwhile, the sensing unit 140 senses a tap applied to the terminal body regardless of whether the display unit 151 is activated. Here, a tap or a tap gesture may denote a gesture hitting the body 100 of the mobile terminal or an object. More specifically, a tap may be understood as an operation of slightly hitting the mobile terminal body 100 or object with a tap subject such as a finger and the like or an operation of allowing a tap subject to be slightly brought into contact with the mobile terminal body 100 or object. For example, when the sensing unit 140 is a touch sensor, the touch sensor may sense a tap by sensing a touch input generated by a tap.
Meanwhile, the tap subject applying such a tap may be a thing capable of applying an external force to the mobile terminal body 100 or object, for example, finger (part with a fingerprint), stylus pen, pen, pointer, first (finger joint) and the like. Further, the tap subject may not be necessarily limited to a thing capable of applying a touch input to a mobile terminal according to the present invention, and the type thereof may be different if it is a thing capable of applying an external force to the mobile terminal body 100 or object.
Further, the tap object applying such a tap may be a thing capable of applying an external force to the mobile terminal body 100 or object, for example, finger (part with a fingerprint), stylus pen, pen, pointer, first (finger joint) and the like. Further, the tap object may not be necessarily limited to a thing capable of applying a touch input to a mobile terminal according to the present invention, and the type thereof may change if it is a thing capable of applying an external force to the mobile terminal body 100 or object.
Meanwhile, an object to which a tap is applied may include at least one of the terminal body and a position out of the body. In other words, the input region of the mobile terminal may be extended to an outside of the terminal body. Accordingly, the position capable of sensing the tap at a position out of the terminal body becomes a virtual input region.
The virtual input region may vary in the area according to a location or object on which the terminal is placed or the strength of a tap. For example, when the terminal is placed on a table, the movement of the terminal may be generated if the user hits the table, thereby sensing the tap therethrough. As a result, the virtual input region is increased as increasing the strength of the hitting. In another example, when the user holds the terminal body, the virtual input region may disappear.
Meanwhile, during the process of sensing a tap, it may be determined that “knock knock” for the purpose of controlling the mobile terminal is sensed only when at least two or more taps are applied within a limited period of time. For example, when a tap is applied once to the 151 by a touch object capable of applying a touch to the display unit 151, the controller 180 can recognize the one tap as a touch input. Namely, in the locked state, inputting a control command by a user is limited, and thus, when a user input is recognized as a touch input, rather than a tap, the controller 180 can disregard the user input.
Thus, when two or more taps (or a plurality of taps) are continuously applied within a limited period of time, the controller 180 can determine that touch inputs for unlocking have been applied.
Hereinafter, consecutively sensing at least two or more taps within a limited period of time may be referred to as “knock knock.” For example, when a second tap is sensed within a limited period of time from a time point at which a first tap is sensed, it may be determined that “knock knock” is sensed. Accordingly, hereinafter, sensing “knock knock” may denote that hitting an object on the terminal body or at a position out of the body is substantially sensed a plural number of times.
Meanwhile, when the sensing unit 140 is a touch sensor, the sensing unit may sense “knock knock” in a different manner according to whether the display unit 151 is activated. For example, when the display unit 151 is activated, it may need to immediately react with a user input, and thus, the touch sensor may execute an active mode in which the touch sensor is maintained in an activate state (including when the touch sensor is switched between an activated state and a deactivated state at a fast cycle over which the touch sensor is regarded as being substantially activated).
In addition, when the display unit 151 is deactivated, in order to reduce battery consumption, the touch sensor may execute a doze or sleep mode in which the touch sensor is switched between an activated state and a deactivated state on a pre-set cycle. Namely, when the display unit 151 is deactivated, the touch sensor may execute the doze or sleep mode and may be activated on every pre-set cycle.
Further, in an embodiment of the present invention, as a cycle on which the touch sensor is activated is shorter, a speed at which “knock knock” applied to the display unit 151 is sensed is increased but power consumed by the touch sensor is increased. Conversely, as the cycle on which the touch sensor is activated is longer, power consumed by the sensing unit 140 is reduced but a speed at which a touch applied to the display unit 151 is decreased.
Thus, the pre-set cycle may be set such that sensing a touch applied to the display unit 151 is so fast that that the user cannot recognize it, while efficiency of power consumption is high. For example, the pre-set cycle may be set such that the touch sensor is activated 30 times (30 Hz) per second. This may be a lowest current level at which a touch may be recognized in a state in which the display unit 151 is deactivated.
Meanwhile, the touch sensor can execute the doze or sleep mode when the display unit 151 is deactivated, and when a first tap is applied to the display unit 151, the touch sensor may execute the active mode. Namely, when it is determined that a tap is applied when the display unit 151 is deactivated, the touch sensor can execute an active mode in order to accurately sense a tap to be applied thereafter. For example, the touch sensor may be set to be activated 120 times per second when the active mode is executed.
Further, when a second tap is not sensed within a predetermined period of time from a point at which the first tap has been applied, the controller 180 can switch the touch sensor from the active mode to the doze or sleep mode. This is to prevent malfunction of the mobile terminal because a tap not intended by the user has been generated.
In addition, the sensing unit 140 may further include at least one of an accelerometer for sensing a tap using a movement of the terminal body, a sound sensor for sensing a tap using a sound generated around the terminal body, a proximity sensor for sensing a tap based on the presence and absence of an object positioned around the terminal body, and a pressure sensor for sensing a tap using pressure applied to the terminal body.
Like the touch sensor, the other sensors included in the sensing unit 140 may be deactivated when the display unit 151 is in a deactivated state, or may be activated at every pre-set period. This is to reduce power consumption caused by the sensors.
Namely, when a first tap is sensed when the display unit 151 is deactivated, the controller 180 can activate one or more sensors included in the sensing unit 140 in order to more accurately sense a second tap to be applied thereafter. The one or more sensors may include a touch sensor, a microphone sensor, a proximity sensor, an RGB sensor, a pressure sensor, and the like, and may be used to distinguish the characteristics of taps (for example, strength of a tap, a position of a tap, a time interval between a first tap and a second tap, an object of a tap, an area of a tap, and the like).
For example, the touch sensor may be disposed in the terminal body to sense a tap using a touch generated on the terminal body. Also, the touch sensor may calculate a position to which a tap is applied, and may identify an object (for example, a finger, a finger nail, a palm, and the like) of a tap using an area touched by a tap.
In another example, the microphone sensor may sense a tap using a sound generated around the terminal body. Also, since a sound has unique frequency characteristics, an object (for example, a finger, a finger nail, a palm, a pen, or the like) of a tap, a pattern of a tap, or the like, may be identified using frequency characteristics of received voice information.
In another example, even when “knock knock” is sensed by the touch sensor, if an object adjacent to a front side of the terminal body is detected by the proximity sensor, the controller 180 can reject the “knock knock.” This is because the mobile terminal 100 held in a bag may be malfunction due to the bag moving.
In another example, the RGB sensor may sense a color of a tap object, and identify a type of the object using the sensed color. Namely, a finger and a touch pen may be distinguished by the RGB sensor. In still another example, the pressure sensor may sense a tap using pressure applied to the terminal body, and calculate strength of the pressure generated by the tap.
In another example, a piezo sensor (or an impact sensor) using a nature that electricity is generated from a surface of a crystal when pressure is applied thereto in a particular direction, may sense a tap. Compared to an accelerometer that senses a movement corresponding to hundreds of hertz (Hz), the piezo sensor may sense a movement corresponding to thousands of hertz (kHz), and thus, the piezo sensor may sense a movement (or an impact) of the mobile terminal more accurately.
In addition, the controller 180 can recognize characteristics of the foregoing tap using the piezo sensor. In more detail, since different physical patterns are generated according to the characteristics of taps generating impact on an object, the piezo sensor may recognize characteristics of a tap using an experimentally obtained physical pattern. The experimentally obtained physical pattern may be set when mobile terminals are released, and stored in the memory 160. The physical pattern may be periodically updated or changed by the user.
Further, in the mobile terminal according to an embodiment of the present invention, in order to sense a tap applied to the body of the mobile terminal, either the accelerometer or the touch sensor may be used, the accelerometer and the touch sensor may be sequentially used, or both the accelerometer and the touch sensor may be used simultaneously.
Meanwhile, the mode in which only the accelerometer is used may be referred to as a first mode, a mode in which only the touch sensor is used may be referred to as a second mode, and a mode in which both the accelerometer and the touch sensor are utilized (simultaneously or sequentially) may be referred to as a third mode or a hybrid mode. In addition, the controller 180 can determine whether “knock knock” is sensed in consideration of sensing signals generated by the forgoing sensors collectively. By doing that, the controller 18 can more accurately recognize the characteristics of a tap, such as a position where a tap is sensed, or the like.
Next, the controller 180 determines whether the sensed touch inputs are matched to a pre-set pattern in step S730. When “knock knock” applied to the display unit a plurality of times is sensed, the controller 180 can analyze an operation pattern of the user formed by sequentially connecting touch points of the sensed touch inputs.
The operation pattern may variously applied according to the number of sensed touch inputs, an absolute or relative position to which the touch inputs were applied, an input speed (or a beat) of the touch inputs, order in which the touch inputs have been applied, the number of touches included in a single touch input (for example, a touch input by one finger or a touch input by two fingers), an area to which the touch inputs have been applied, strength of the touch inputs, whether the touch inputs are maintained to be in contact with the terminal body) (tap and hold), and the like.
In an embodiment, the controller 180 can determine whether the sensed touch inputs have been sequentially applied to at least one region according to a pre-set pattern among virtual regions of the display unit divided into the virtual regions based on pre-set order. For example, the virtual regions may include first, second, third, and fourth virtual regions, and the first, second, third, and fourth virtual regions may correspond to different numbers, respectively, and the different numbers may be given in order from the left to the right or from top to bottom based on the positions of the first, second, third, and fourth regions.
In this instance, when the sensed touch inputs have been sequentially applied to at least one of the first, second, third, and fourth regions according to a pre-set pattern based on pre-set order, the controller 180 can determine that the touch inputs are matched to the pre-set pattern.
In another embodiment, the controller 180 can calculate position coordinates to which a touch input has been applied. Position coordinates may be expressed as coordinates (x,y) based on a horizontal axis (x axis) and a vertical axis (y axis) of the display unit. The controller 180 can analyze an operation pattern of the user formed by sequentially connecting touch points based on the calculated position coordinates. The controller 180 can differentiate between an operation pattern for unlocking and an operation pattern unrelated to unlocking.
The controller 180 can analyze an operation pattern based on relative positions of touch points. In this instance, an nth touch input needs to be applied to a position satisfying a pre-set condition from a point to which an (n−1)th touch input has been applied. For example, when a second touch input does not satisfy a pre-set condition in relation to the first touch input, the controller 180 disregards the first touch input.
Further, when the second touch satisfy the pre-set condition in relation to the first touch input, the controller 180 determines whether a third touch input satisfies the pre-set condition in relation to the second touch input. When all of the touch inputs constituting the operation pattern satisfy the pre-set condition, the controller 180 can determine that the pre-set pattern has been sensed. The pre-set condition may relate to a distance between two touch points, a direction of the two touch points, and an angle between a virtual reference axis based on a vertical axis of the terminal body and straight lines linking two points.
Referring again to
The controller 180 analyzes the operation pattern based on the sensed touch inputs and determines whether the analyzed operation pattern (or a pre-set pattern) is matched to an operation pattern (or a pre-set pattern0 defined as a release command. The controller 180 can digitize a matching rate, and when the digitized matching rate is greater than a reference value, the controller 180 can determine that the operation pattern is matched to the pre-set pattern.
Thereafter, the controller determines whether characteristics of the sensed touch inputs are identical to any one of pre-set characteristics in step S770. In more detail, the controller 180 can compare the characteristics of the sensed touch input with characteristics set as a shortcut function to determine whether they are identical.
The sensed touch inputs may be sensed to have various sizes at various positions corresponding to at least one region of the display region of the display unit. The sensed touch inputs may be input by various objects such as a finger, a finger in a glove, a touch pen, or the like. Namely, the sensed touch inputs may be matched to the pre-set pattern and may have various characteristics.
In more detail, the characteristics of the sensed touch inputs may be varied according to at least one of a position of a region to which the sensed touch inputs have been applied, a size of the region to which the sensed touch inputs have been applied, a type of object which has applied the sensed touch inputs, and the number of touches included in a final touch input among the sensed touch inputs.
For example, when the sensed touch inputs are matched to the pre-set pattern and have first characteristics, the controller 180 can release a locked state and display a first execution screen on the display unit, and when the sensed touch inputs are matched to the pre-set pattern and have second characteristics different from the first characteristics, the controller 180 can release the locked state and display a second execution screen different from the first execution screen on the display unit.
The sensed touch inputs may be matched to the pre-set pattern. Here, however, when there are no pre-set characteristics or when the sensed touch inputs are not identical to the pre-set characteristics (No in S770), the controller 180 displays a home screen or the last execution screen when unlocking in step S790. The home screen may include at least one object, and the object may be an icon or a widget of an application installed in the mobile terminal.
Further, when the sensed touch inputs are matched to the pre-set pattern and identical to any one of pre-set characteristics (Yes in S770), an execution screen corresponding to the any one pre-set characteristics is displayed in step S792. The memory unit 160 stores the pre-set characteristics and information regarding an execution screen corresponding to the pre-set characteristics, and thus, the controller 180 can display an execution screen corresponding to the characteristics of the sensed touch inputs on the display unit.
In this instance, the controller 180 executes one or more control functions related to the execution screen such that the execution screen is displayed on the display unit 151. Here, the control functions may refer to any type of function that can be executed or driven in the mobile terminal 100. For example, one of the control functions may be an application installed in the mobile terminal 100. For example, “execution of a certain function” may refer to “execution or driving of a certain application.”
In another example, a function executable in the mobile terminal 100 may be a function generating an event. Here, the generated event may be a message origination event, a call origination event, or the like. Meanwhile, the event may be an event generated from an application installed in the mobile terminal.
In another example, a function executable in the mobile terminal 100 may be a function required for basic driving of the mobile terminal 100. For example, the function required for basic driving may be a function of turning on or off Wi-Fi, a function of setting a communication network, a function of changing configuration information of the mobile terminal 100, or the like.
Namely, by applying a plurality of touch inputs to the display unit 151 in a deactivated state, the user may release a locked state and simultaneously execute a function desired to be executed. Meanwhile, when the display unit is deactivated, guide information for receiving a touch corresponding to the pre-set pattern is not output.
The pre-set characteristics will be described in detail. When sensed touch inputs are matched to the pre-set pattern, the controller 180 selectively displays at least one execution screen based on at least one of a position and a size of a region to which the sensed touch inputs have been applied, among the plurality of pre-set execution screens. For example, when a plurality of touch inputs matched to the pre-set pattern are sensed in a first pre-set region of the display region of the display unit, the controller 180 can release the locked state, simultaneously execute a function corresponding to the positional characteristics of the first region, and display an execution screen according to the execution on the display unit 151. Further, when a plurality of touch inputs matched to the pre-set pattern are sensed in a region different from the first region, the controller 180 can display a home screen or an execution screen of the last executed application.
The controller 180 can divide the display unit 151 into a plurality of regions, and set the plurality of regions to correspond to different execution screens, respectively. For example, when an entire region of the display unit is divided into an upper region and a lower region, the controller 180 can set a first execution screen in the upper region and a second execution screen in the lower region. To conclude, when a plurality of touch inputs matched to the pre-set pattern are input to the upper region, a locked state of the mobile terminal is released and the first execution screen is displayed.
The plurality of regions as described above may be formed to have various shapes according to a user setting. As described above, the display unit 151 may be divided into upper and lower execution regions or may be divided into first to fourth execution regions. Also, execution screens corresponding to the regions may be variously modified according to a user setting.
In addition, the pre-set characteristics may relate to the number of touches included in a final touch input among the sensed touch inputs. For example, when a touch input is applied by one finger, the number of touches included in a final touch input is one, and when a touch input is applied by two fingers, the number of touches included in the final touch input is two. The controller 180 can display different execution screens according to the number of touches included in the final touch input.
Also, the pre-set characteristics may relate to a type of object which has applied the sensed touch inputs. The controller 180 can identify a type of an object which has applied a touch input using a touched area, a sound generated when a touch is applied, or the like. For example, the controller 180 can determine whether the sensed touch inputs have been applied by a finger, a touch pen, or a gloved hand. Based on a type of the object, the controller 180 can select an execution screen to be displayed on the display unit from among a plurality of pre-set execution screens when a locked state is released.
Meanwhile, the mobile terminal according to an embodiment of the present invention may provide a multi-user function. Here, the multi-user function refers to a function allowing multiple users to log into a single mobile terminal through different accounts and use different settings for each account. Home screen settings, sound settings, executable app settings, folder settings, and the like, may be differently set in each account. Namely, different home screens may be set for multiple users.
Here, when the sensed touch inputs are matched to a pre-set pattern, the controller 180 can release a locked state, log in for any one of the multiple users based on characteristics of the sensed touch inputs, and display a home screen corresponding to the any one user. For example, when the sensed touch inputs have first characteristics, the controller 180 can display a first home screen corresponding to a first user, and when the sensed touch inputs have second characteristics, the controller 180 can display a second home screen corresponding to a second user.
Further, when the sensed touch inputs are matched to the pre-set pattern, a final touch input among the touch inputs constituting the sensed touch inputs may not be released but maintained in a contact state. When the final touch input is maintained, rather than being released for a pre-set period of time, the controller 180 can display graphic objects corresponding to different functions around the position where the final touch input has been sensed. Thereafter, when a drag input, starting from a touch corresponding to the final touch input, to reach any one of the graphic objects is sensed, the controller 180 can processes a function corresponding to the any one graphic object.
Types of graphic objects displayed around the position where the final touch input has been sensed may vary according to characteristics of the sensed touch inputs. In more detail, types of the graphic objects may be varied by at least one of a position of a region to which the sensed touch inputs have been applied, a size of the region to which the sensed touch inputs have been applied, a type of an object used to apply the sensed touch inputs, and the number of touches included in a final touch input among the sensed touch inputs.
For example, the sensed touch inputs may be matched to a pre-set pattern, the number of touches included in the final touch input among the sensed touch inputs may be one, and the final touch input may be maintained for a pre-set period of time, rather than being released. In such a case, the controller 180 can display icons fixed at the same positions around the final touch input, although a page is shifted in the home screen composed of a plurality of pages. In this instance, the icons are formed to execute different applications.
In another example, the sensed touch inputs may be matched to a pre-set pattern, the number of touches included in a final touch input among the sensed touch inputs may be two, and the final touch input may be maintained for a pre-set period of time, rather than being released. In such a case, the graphic objects may include icons formed to perform a function of making a call to a particular contact number. The particular contact number may be a contact number set by the user as bookmark or may be a contact number included in the recent call list.
In addition, although a plurality of touch inputs applied to the display unit 151 are sensed when the display unit 151 is deactivated, a pattern formed by the sensed touch inputs may not be matched to a pre-set pattern for unlocking. Namely, touch inputs unrelated to unlocking (or an erroneous operation pattern) may be sensed. In this instance, the controller 180 can not release the locked state and maintain the display unit 151 in the deactivated state. Namely, the controller 180 ignores the sensed touch inputs. In this instance, however, in order to inform the user that tapping has been erroneously applied, the controller 180 can inform the user that there is no executable function (or that a tap pattern has been erroneously input) using a light emitting unit.
Meanwhile, the erroneous operation pattern may be continuously sensed. Namely, taps unrelated to unlocking may be repeatedly sensed by a reference number of times within a reference period of time. In such a case, the controller 180 can maintain the locked state but activate the display unit 151 and display a locked screen formed to receive a password. When the erroneous operation pattern is repeatedly input, it means that the user has a wrong password, and thus, the controller 180 displays a locked screen that may be unlocked on the display unit 151. Thereafter, the user can input a password using a virtual keypad of the locked screen and switch the locked state to a released state.
Next,
Referring to
In more detail, referring to
The display unit 151 is divided into virtual regions, and at least one of a position and a size of the virtual regions is varied based on a touch point where the plurality of touch inputs are sensed in the display unit 151. For example, in the drawings, it is illustrated that virtual regions include first, second, third, and fourth virtual regions, and at least one of the position and size of the virtual regions is varied according to a position where the first, second, third, and fourth touch inputs sequentially applied to the display unit are sensed.
The first, second, third, and fourth regions correspond to different numbers, respectively. For example, the different numbers may be given in order from the left to the right or from the top to the bottom based on the positions of the first, second, third, and fourth regions.
The controller 180 determines whether the sensed touch inputs include a plurality of touch inputs sequentially applied to at least one of the first, second, third, and fourth regions in pre-set order according to a pre-set pattern. For example, as illustrated in
Thereafter, in releasing a locked state, the controller 180 can select an execution screen to be displayed on the display unit 151 switched to an activated state according to characteristics of the sensed touch inputs. In more detail, the display unit 151 may be divided into a plurality of regions respectively corresponding to different execution screens in the deactivated state, and the controller 180 displays an execution screen corresponding to any one of the regions to which the sensed touch inputs have been applied.
For example, the display unit 151 may be divided into an upper region 842 and a lower region 844. The upper region 842 may be set to execute a call origination function and display an execution screen according to execution of the call origination function. The lower region 844 may set to execute a messenger function and display an execution screen of the messenger function. Namely, an execution screen according to execution of a call origination function and an execution screen of a messenger application may be set in advance as a plurality of execution screens to be displayed when a locked state is released.
Subsequently, as illustrated in
Meanwhile, as illustrated in
As described above, the user of the mobile terminal according to an embodiment of the present invention can execute different functions by simply applying a plurality of touch inputs matched to a pre-set pattern to different regions of the display unit. Namely, the mobile terminal according to an embodiment of the present invention provides a more intuitive, relatively simple user interface environment to users.
Further, the mobile terminal according to an embodiment of the present invention can display different execution screens according to the number of touches included in a final touch input among a plurality of touch inputs matched to a pre-set pattern. For example, when the number of touches is one, a first execution screen matched thereto may be displayed, and when the number of touches is two, a second execution screen matched thereto may be displayed.
For example, when the number of touches is one, a home screen may be displayed as illustrated in
For example, as illustrated in
In another example, as illustrated in
Further, the controller 180 can output notification information indicating that the voice recognition function has been activated, using at least one of visual, tactile, and audible schemes. Meanwhile, when visual notification information is output, the controller 180 can activate only a portion of the display unit 151 to output the notification information thereto.
Meanwhile, the mobile terminal according to an embodiment of the present invention may provide a multi-user function. Here, the multi-user function refers to a function allowing users to log in to a single mobile terminal through different accounts and use different settings for each account.
According to the multi-user function, home screen settings, sound settings, executable app settings, folder settings, and the like, may be differently set in each account. Different home screens may be set for each of users registered as multi-users. In more detail, a background of a home screen, a disposition of icons, and the like, may be freely set by users. Accordingly, multiple users may use a single terminal according to a scheme fitting themselves.
Here, when sensed touch inputs are matched to a pre-set pattern, the controller 180 can release a locked state and perform log-in with respect to any one of the multiple users based on characteristics of the sensed touch inputs. In addition, the controller 180 can execute a log-in function with respect to various users according to at least one of a position to which touch inputs have been applied, a size of the touch inputs, the number of touches included in a final touch input, and a type of an object used to apply touch inputs. Thus, the controller 180 can display a home screen corresponding to any one of the user.
For example, as illustrated in
So far, the embodiment in which various execution screens are displayed according to characteristics of sensed touch inputs when a single pattern is set in advance has been described, but a plurality of patterns may also be set in advance. Namely, a plurality of patterns for releasing a locked state may exist in the mobile terminal. The plurality of pre-set patterns may be set to display different execution screens. Hereinafter, a method of controlling a mobile terminal using a plurality of pre-set patterns will be described in detail.
Referring to (a) of
The home screen will be described in detail. The home screen may include at least one object, and the at least one object may be an icon or a widget of an application installed in the mobile terminal. Meanwhile, the home screen may include a plurality of pages according to a user selection or the number of applications installed in the mobile terminal, and at least one of the plurality of pages may be output to the display unit 151 according to a user selection.
The home screen may also include at least one of an identification information region 1210 in which identification information with respect to a page output to the display unit 151 is displayed, a state information region 1220 in which state information of the mobile terminal 100 is displayed, and a pre-set region 1230 in which icons or pre-set applications are displayed. Identification information indicating how many pages to a plurality of pages the currently output page is may be output to the identification information region 1210.
Also, at least one of antenna information of the mobile terminal 100, communication mode information of the mobile terminal 100, battery information of the mobile terminal 100, information regarding an event that has occurred, information regarding a pre-set function, and time information may be output to the state information region 1220.
Also, icons and widgets corresponding to particular applications previously set by the controller 180 or according to a user selection may be fixedly displayed in the pre-set region 1230. In more detail, icons displayed in the pre-set region 1230 may be fixedly displayed at the same position even though a page is changed in the home screen including a plurality of pages. The icons displayed in the pre-set region 1230 may be icons previously set by the user or may be icons of applications most frequently executed among the applications installed in the mobile terminal.
Also, a background screen can be displayed on the display unit 151 according to a user selection or a setting by the controller 180, and the controller 180 can control the display unit 151 to display the background screen and the home screen in an overlapping manner. Meanwhile, when a widget is output to the display unit 151, the background screen may not be displayed, and a background screen output to the widget may be set to be different from a background screen of the home screen.
When a locked state is executed, as illustrated in (b) of
Further, when a final touch input, among touch inputs included in the sensed touch inputs, is maintained to be in contact with the mobile terminal (which is called “hold”), rather being released, the controller 180 displays a plurality of graphic objects around a touch point of the final touch input. For example, as illustrated in (b) of
The graphic objects are displayed around a position where the final touch input has been sensed, and include graphic objects respectively corresponding to different functions. Here, the different functions refer to functions that can be executed in the mobile terminal 100. Namely, the different functions may refer to any type of function that can be executed or driven in the mobile terminal 100. For example, the executable function may be an application installed in the mobile terminal 100 or a function required for a system operation of the mobile terminal 100 such as a function of changing configuration information of the mobile terminal 100, a function of outputting a notification panel for displaying an unread event, or the like.
In particular, as illustrated in (c) of
Subsequently, the controller 180 can allow the user to select any one of the graphic objects. In more detail, the controller 180 can select any one graphic object based on a drag input continuously moving from a position corresponding to the final touch input. For example, as illustrated in (c) of
When any one of the graphic objects is selected, the controller 180 executes the selected function. For example, as illustrated in (d) of
Meanwhile, types of graphic objects displayed around the final touch input may vary according to characteristics of sensed touch inputs. For example, as illustrated in
Further, as illustrated in
Here, when a final touch input is released within a reference time from a point in time at which the final touch input was input, the controller 180 executes a selected function and displays an execution screen. Further, when the final touch input is held, the controller 180 displays graphic objects related to the selected function in at least on region of the display unit.
In other words, the controller 180 selects a function corresponding to the characteristics of the sensed touch inputs, as a main function. When the final touch input is held, the controller 180 searches sub-functions that belong to the selected main function. The controller 180 subsequently displays different graphic objects formed to execute the searched sub-functions, around the point to which the final touch input was applied. Namely, when the final touch input is held, the controller 81 displays graphic objects corresponding to the sub-functions, and when the final touch input is not held, the controller 180 executes the main function and displays an execution screen according to the execution of the main function.
For example, with respect to a knock code applied by two fingers, a call function (or an application for making a call) may be set as a shortcut function. In this state, when a knock code is applied by two fingers, the controller 180 can select the call function as a main function. Here, as illustrated in (b) of
Meanwhile, when the final touch input is held, the controller 180 can select functions forming a sub-menu function of the call function, as sub-functions. For example, functions of performing call origination to a contact number set as bookmark or a contact number included in the recent call list may be selected as sub-functions. In this instance, as illustrated in (b) of
Meanwhile, when a drag input continuously moving fro a position corresponding to the final touch input is sensed, as illustrated in (c) of
Besides, when a browser execution function is selected as a main function, sub-functions of the browser execution function may be functions of displaying a page registered as bookmark. Also, when a function of activating a camera is selected as a main function, a function of capturing an image and a function of capturing video may be selected as sub-functions.
The main function and sub-functions may be set in advance by the user or may be automatically selected by the terminal. For example, only the main function immediately executed according to first characteristics of the knock code may be set. Even In this instance, when the final touch input among the touch inputs corresponding to the first characteristics is held, the controller 180 can automatically search sub-functions included in the main function and display graphic objects formed to execute the searched sub-functions, around the final touch input.
Thus, even though one knock code is registered, different execution screens are displayed depending on whether a final touch input is held, a simple user interface may be provided.
Meanwhile, as illustrated in
Next,
When all the touch inputs applied to the upper region and the lower region satisfy a pre-set pattern, the controller 180 can release a locked state, divide the display unit 151 into first and second regions, and display different execution screens in the first and second regions. For example, execution screens of different applications which have been executed lately may be displayed in the first and second regions 1510 and 1520, respectively.
Also, according to an embodiment of the present invention, the controller 180 can sense a touch input having a predetermined area or greater. As illustrated in
According to an embodiment of the present invention, a new interface may be provided such that user privacy may be simply guaranteed through a unique knock code of a terminal use. In more detail, when a knock code formed to identify a user is input to a touch screen, the controller 180 can display a closed home screen allowing only a user to access. Hereinafter, a closed home screen will be referred to as “my room.”
Meanwhile, an identifier 23 indicating that the secret folder has been entered may be displayed on the display unit 151. The identifier 23 may be displayed as an icon in an indicator region 60. Also, the identifier may be displayed in the form of unique text (for example, “My Room” or “Owner Mode”).
The method of indicating that the secret folder has been entered through input of a user signature is not limited to the foregoing example and may be variously modified to be performed. Means for feeding back entry to the secret folder may include a visual effect, an audible effect, vibration generation, and the like. For example, when the secret folder is entered through input of a user signature, the controller 180 can display the indicator region 60 of the secret folder screen such that it is visually differentiated from that before the secret folder was entered. For example, the controller 180 can change a color of the indicator region 60 and display a changed color.
When a pinch-out input is received on the display unit 151, the controller 180 can remove the at least one icon and maintain displaying only the background screen 42. The controller 180 can activate and display a region (I, called a “knock pad”) for receiving a knock code on the background screen 42. When a knock code is input to the knock pad I, the controller 180 outputs my room to the display unit 151.
Meanwhile, in
Next,
Referring to
The predetermined drag input may be an input of dragging starting from the indicator region downwardly. The drag input may include a drag input by one finger or a drag input by two fingers of the user. The controller 180 can activate the knock pad to receive a knock code in response to the drag input in step S1710.
Upon receiving the knock code on the knock pad, the controller 180 recognizes an input knock code in step S1720. A method of recognizing a knock code has been described above with reference to
When a touch input of dragging the indicator region 60 downwardly by a multi-touch is received, a status window 61 slid by the touch input, including a region 62 for receiving a knock code, may be displayed. Namely, when the user drags the indicator region 60 with one finger, the controller 180 can provide a status window including state information of the terminal, while when the user drags the indicator region 60 with two fingers, the controller 180 can provide a knock code input region for entering a secret folder.
Referring to (a) & (b) of
Referring to (c) of
Meanwhile, in
In
Referring to
In more detail, after a first input T1 dragging down the indicator region 60 with a first finger F1 of the user is received, the controller 180 can receive a second input T2 of touching a certain point in the vicinity of the dragged point or within a particular distance L1 from a lower end of the display unit 151 by a second finger F2, with the first input T1 maintained. General status information of the mobile terminal 100 may be displayed on the status window 61 slid to be shown by the first input T1. Here, when only the first input T1 is received and the second input T2 does not exist, if the first input 1 is released (the drag input is released), the status window 61 may be returned to the original state (may be dragged up to disappear).
In addition, when the status window 61 is fixed to the second input T2 point according to the second input T2, a third input T3 of dragging up the status window 61 may be received. The third input T3 may be an input dragging up from the point of the second input T2 by a predetermined length (for example, L3). Then, the controller 180 can activate the knock pad I corresponding to the predetermined length L3. The status window 61 is displayed above the knock pad I.
When a user signature is received in the activated knock pad I, the controller 180 can display my room in at least one region of the display unit 151. For example, notification information 91 and 92 related to the secret folder may be displayed in the knock pad I. Meanwhile, the status window 61 displayed on the knock pad I may display general status information 85 and 86 of the mobile terminal 100.
In addition, a rear surface of the mobile terminal 100 according to an embodiment of the present invention may include a rear input module. The rear input module may be positioned to be adjacent to the camera module exposed from the rear surface of the terminal body. The rear input module is manipulated to receive an input for controlling an operation of the mobile terminal 100, and various types of content may be input. For example, a command such as ON/OFF of power, start, end, scroll, or the like, adjustment of a size of a sound output from an audio output module, switch to a touch input mode of the display unit, or the like, may be received.
According to an embodiment of the present invention, a position of the dragged-down status window 61 may be fixed through input applied to the rear input module. Namely, referring to
Referring to
Subsequently, when the touch continues to move from one end to the other end, the controller 180 can change a display region of the status window 61 based on the movement of the touch. For example, when the touch continuously moves down from one point of an upper end of the display unit 151, a display region of the status window 61 may be enlarged from the upper end of the display unit 151 to a position where the touch is terminated. Namely, an animation effect as if the status window 61 goes down from the upper end may be generated.
The status window 61 may include graphic objects for setting function required for basic driving of the mobile terminal. For example, the required functions may include a function of turning on or off Wi-Fi, a function of activating or deactivating Bluetooth, a function of establishing a communication network, a function of changing configuration information of the mobile terminal, and the like.
Meanwhile, when the status window 61 is displayed, a touch may be applied to one end of the display unit 151 from which the status window 61 first started to be displayed. In this instance, in response to the touch sensed on the one end of the display unit 151, the controller 180 can output at least a portion of the knock pad 62 to the display unit 151.
Subsequently, when the touch continues to move from the one end to the other end, the controller 180 can change a display region of the knock pad 62 based on the movement of the touch. Accordingly, an effect as if a plurality of window overlap with each other may be provided.
Meanwhile, when the knock pad 62 is displayed, the controller 180 can sense a plurality of touch inputs. Also, as described above with reference to
According to the embodiment of the present invention described above with reference to
Even without having to enter the secret folder, the user may be conveniently provided with various types of notification information regarding items kept in storage in the secret folder by utilizing the indicator region. Namely, in general, in order to check update information regarding items kept in the secret folder, a user should enter the secret folder through input of a knock code and select an updated application, thus checking updated content.
However, according to an embodiment of the present invention, when a knock code is received through the indicator region of the mobile terminal, notification information related to the secret folder can be easily accessed using the indicator region, without having to perform the plurality of steps as described above.
Next,
In this instance, the user can apply a plurality of touch inputs that touch one region according to a pre-set pattern among the virtual regions of the display unit 151 in a deactivated state in reverse order of the pre-set order. For example, as illustrated in
Namely, when the touch inputs are applied in the pre-set order, the home screen is displayed when the locked state is released, and when the touch inputs are applied in reverse order of the pre-set order, my room is displayed when the locked state is released.
So far, the method of displaying various execution screens using one knock code has been described in detail. However, according to another embodiment of the present invention, the locked state may be released by different patterns and the deactivated display unit 151 may be switched to an activated state. Also, the plurality of patterns may be set to display different execution screens. For example, a first knock code may be set to display a first execution screen, and a second knock code may be set to display a second execution screen. Namely, various execution screens may be displayed by various patterns.
Next,
In the mobile terminal according to an embodiment, even when the display unit 151 is deactivated (or in an OFF state), a speed at which a plurality of touch inputs are applied may be calculated. In more detail, the controller 180 can calculate a speed at which touch inputs are applied using a time difference between a first applied touch input and a finally applied touch input among a plurality of touch inputs matched to a pre-set pattern.
In order to release a locked state, the controller 180 can determine whether to activate the display unit 151 based on the calculated speed. In more detail, when touch inputs are applied at a speed faster than a reference speed, the controller 180 can output context information by voice using the audio output unit 152 (please refer to
