This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0133248, filed on Oct. 24, 2019, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.
The present relates generally to an electronic device including a display and a method for controlling a display operation thereof.
Electronic devices with diverse functions may be implemented as multimedia players having complex functions, such as multimedia players with still or moving image capturing functions, music or video file playback functions, gaming functions, broadcast receiving functions, or call functions. Such an electronic device may include a display to display screen related to functions.
An electronic device may include a proximity sensor in an area of a surface thereof (e.g., on the front surface on which the display is positioned) that is capable of sensing whether or not entities (or objects) approach. An electronic device may allow the user to easily control the operation (e.g., turning on/off) of the display thereof by using the proximity sensor during a telephone call.
The disclosure has been made to address the above-mentioned problems and disadvantages, and to provide at least the advantages described below.
According to an aspect of the disclosure, an electronic device includes a housing including a front plate, a rear plate, and a side member; a display having a first surface visible through the front plate; an inertial sensor; a proximity sensor disposed on a second surface of the display; a processor; and a memory. The memory may store instructions that, when executed, cause the processor to determine a user's posture through the inertial sensor, in response to activation of a specific application using a function of the proximity sensor; determine a movement of the electronic device through the inertial sensor; determine the user's intent to use the display, based on the user's posture and the movement of the electronic device; and determine a configuration value of the proximity sensor, based on the determined intent to use the display.
According to another aspect of the disclosure, a method for operating an electronic device includes determining a user's posture through an inertial sensor, in response to activation of a specific application using a function of a proximity sensor; determining a movement of the electronic device through the inertial sensor; determining the user's intent to use a display, based on the user's posture and the movement of the electronic device; and determining a configuration value of the proximity sensor, based on the determined intent to use the display.
The above and other aspects, features, and advantages of certain embodiments of the present disclosure will be more apparent from the following description taken in conjunction with the accompanying drawings, in which:
An electronic device according to various embodiments may determine the user's intent to use a display and may configure a recognition criterion to be used by a proximity sensor to recognize an approaching object, based on the user's intent to use the display, thereby improving the auto screen off function.
An electronic device according to various embodiments may configure a relatively high criterion for recognizing an approaching object, if it is determined that the user has an intent to use a display while a specific application that uses a function of a proximity sensor is activated, thereby preventing the display screen from turning off in response to a temporary approach of an object (for example, the user's hand).
An electronic device according to various embodiments may configure a relatively low criterion for recognizing an approaching object, if it is determined that the user has no intent to use a display while a specific application that uses a function of a proximity sensor is activated, such that the display screen is quickly turned off even in the case of a temporary approach of the object.
An auto screen off function refers to a function of turning off the screen when the proximity sensor senses an approaching object such that, while a specific application (for example, a telephone call application) is being executed, the user's inadvertent touch input (for example, touch input by his/her ears or cheeks) is not sensed. If the user manipulates a user interface through the display while a specific application (for example, a voice communication application) using a proximity sensor function is activated, a user input occurring near the proximity sensor may turn off the display against the user's intent.

The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.
The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.
The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., PCB). According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 197.
At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).
According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

According to an embodiment, the pre-processing or post-processing may be performed, for example, based at least in part on one or more characteristics of the image data or one or more characteristics of the display 210.
The mapping module 237 may generate a voltage value or a current value corresponding to the image data pre-processed or post-processed by the image processing module 235. According to an embodiment, the generating of the voltage value or current value may be performed, for example, based at least in part on one or more attributes of the pixels (e.g., an array, such as an RGB stripe or a pentile structure, of the pixels, or the size of each subpixel). At least some pixels of the display 210 may be driven, for example, based at least in part on the voltage value or the current value such that visual information (e.g., a text, an image, or an icon) corresponding to the image data may be displayed via the display 210.
According to an embodiment, the display device 160 may further include the touch circuitry 250. The touch circuitry 250 may include a touch sensor 251 and a touch sensor IC 253 to control the touch sensor 251. The touch sensor IC 253 may control the touch sensor 251 to sense a touch input or a hovering input with respect to a certain position on the display 210. To achieve this, for example, the touch sensor 251 may detect (e.g., measure) a change in a signal (e.g., a voltage, a quantity of light, a resistance, or a quantity of one or more electric charges) corresponding to the certain position on the display 210. The touch circuitry 250 may provide input information (e.g., a position, an area, a pressure, or a time) indicative of the touch input or the hovering input detected via the touch sensor 251 to the processor 120. According to an embodiment, at least part (e.g., the touch sensor IC 253) of the touch circuitry 250 may be formed as part of the display 210 or the DDI 230, or as part of another component (e.g., the auxiliary processor 123) disposed outside the display device 160.
According to an embodiment, the display device 160 may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module 176 or a control circuit for the at least one sensor. In such a case, the at least one sensor or the control circuit for the at least one sensor may be embedded in one portion of a component (e.g., the display 210, the DDI 230, or the touch circuitry 150)) of the display device 160. For example, when the sensor module 176 embedded in the display device 160 includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) corresponding to a touch input received via a portion of the display 210. As another example, when the sensor module 176 embedded in the display device 160 includes a pressure sensor, the pressure sensor may obtain pressure information corresponding to a touch input received via a partial or whole area of the display 210. According to an embodiment, the touch sensor 251 or the sensor module 176 may be disposed between pixels in a pixel layer of the display 210, or over or under the pixel layer.

The electronic device 101 according to various embodiments may have a housing (not illustrated) (for example, housing 350 in
The processor 310 is configured to be able to perform control of respective components of the electronic device 101 and/or communication-related computation or data processing, and may include at least some of the components and/or functions of the processor 120 in
The memory 340 may store instructions regarding the processor 310 described above.
The display 320 may display various screens under the control of the processor 310. The display 320 may be implemented as a touch sensor panel (TSP) capable of recognizing the touch or approach (e.g., hovering) of various external objects (e.g., a user's hands). The touch sensor panel may have various structures (G2, G1F, GFF, GFd, GF2, GF1, GF, etc.) and types, and contents regarding various embodiments disclosed in this document are all applicable regardless of the structure and type of the touch sensor panel. The display 320 may implemented in various forms including a liquid crystal display (LCD) and an organic light-emitting diode (OLED).
One surface of the display 320 may be seen through the front plate of the housing.
The sensor module 330 is configured to sense the operating state of the electronic device 101 or the environment state of the outside and to produce an electric signal or a data value corresponding to the sensed state, and may include at least some of the components and/or functions of the sensor module 176 in
The sensor module 330 may include at least one of a proximity sensor 331 or an inertial sensor 333.
The proximity sensor 331 may be configured to sense an approach of a peripheral object without physical contact. The proximity sensor 331 may include, for example, an optical proximity sensor, a radio frequency (RF) proximity sensor, a capacitive proximity sensor, or an ultrasonic proximity sensor.
The optical proximity sensor may include a light emitter configured to emit light and a light receiver configured to light reflected by an external object. The optical proximity sensor may measure the amount of light which is emitted by the light emitter, for example, which is reflected by an external object, and which is directed to the light receiver, thereby determining whether or not an object exists or measuring the distance from the object (moving towards or away from the same). The optical proximity sensor may use, for example, infrared rays or visible rays.
The RF proximity sensor according to various embodiments may transmit an RF signal through at least one antenna and may receive the RF signal reflected by an external object, thereby measuring the distance from the external object. The RF proximity sensor may sense whether or not an object approaches by using multiple RF signals, which are connected to a frequency control signal, and which have different frequencies.
The capacitive proximity sensor may be configured to sense whether or not an external object approaches by using a change in the capacitance thereof. The capacitive proximity sensor may recognize the user's approach by using a hovering function of the touch sensor panel, for example. The ultrasonic proximity sensor may be configured to sense the approach of an object, based on ultrasonic waves, by using a speaker and a microphone.
The proximity sensor 331 may be disposed below the display 320 (or on the lower portion (e.g., under panel) of the display 320). When the front surface of the display 320 is seen through the front plate of the housing of the electronic device 101, the proximity sensor 331 may be disposed on the rear surface of the display 320. The proximity sensor 331 may be disposed between the display 320 and the rear plate of the housing.
The processor 310 may drive the proximity sensor 331 in response to activation of a specific application using a function of the proximity sensor 331 (e.g., a telephone speech application or a voice message application).
The inertial sensor 333 may be configured to detect the inertia of a movement, thereby measuring the acceleration, speed, direction, or distance of the electronic device 101 during a movement thereof. The inertial sensor 333 may include at least one of an accelerometer, a gyroscope, or a geomagnetic sensor.
The acceleration sensor according to various embodiments may be configured to measure an acceleration acting along x/y/z axes. The acceleration sensor may measure the intensity of acceleration or impact of an object. The acceleration sensor may measure a dynamic force of an acceleration, a vibration, an impact, etc., thereby producing an acceleration signal. If there is no movement of the electronic device 101 including the acceleration sensor, a gravitational acceleration vale may be measured. If the electronic device 101 including the acceleration sensor moves, a vibration in the direction of movement may be measured as the amount of change in acceleration.
The gyroscope according to various embodiments may be configured to measure an angular velocity acting along x/y/z axes. The gyroscope may measure the amount of rotation of the electronic device 101 with regard to each axis by using angular velocity information measured for each axis, for example.
The geomagnetic sensor may be configured to measure the azimuth of the electronic device 101, based on a geomagnetic field, by using the magnitude and direction of a geomagnetic field vector measured along x/y/z axes.
The processor 310 may recognize a posture (or motion) of the electronic device 101 and/or the user by using the inertial sensor 333. When the user makes a phone call by using the electronic device 101, the processor 310 may determine various postures of the user by using the inertial sensor 333.
The processor 310 may track a change in posture of the user by through the inertial sensor 333, and may determine the user's posture on the basis of the tracking result. The processor 310 may extract sensor data (e.g., an acceleration value and/or a gravity value) provided by the acceleration sensor of the inertial sensor 333, may track the user based on the extracted sensor data, and may determine the user's posture based on the result of tracking the user.
The processor 310 may measure the angle of the electronic device 101 by using the inertial sensor 333, for example. The processor 310 may calculate the angle of the electronic device 101 with regard to each axis by using the acceleration value of the inertial sensor 333 with regard to each axis and the vector sum (e.g., a square root of an acceleration value with regard to each axis) of the acceleration sensor.
The processor 310 may determine the user's posture by using the angle of the electronic device 101 calculated with regard to each axis. It will be assumed, for example, that the tilt angle of the acceleration sensor (e.g., angle with reference to y-axis) is 0° when the display 320 of the electronic device 101 faces upwards, and the tilt angle of the acceleration sensor is 90° when the electronic device 101 stands upright. The processor 310 may determine that the user is viewing the display 320 of the electronic device 101 in an upright position if the tilt angle of the acceleration angle is equal to/larger than 0° and less than 60°. The processor 310 may determine that the user is viewing the display 320 of the electronic device 101 in a lying position if the tilt angle of the acceleration angle is equal to/larger than 120° and less than 160°. The processor 310 may determine that the user is viewing the display 320 of the electronic device 101 in a sideways lying position if the angle of the acceleration angle with regard to y-axis is 0°, and if the angle thereof with regard to x-axis is equal to/larger than −30° and less than 30°.
The posture in which the user uses the electronic device 101 during a phone call may be variously classified, as in the example given in Table 1 below, in each state (or situation) in which the user uses the electronic device 101:
The processor 310 may determine the user's posture by using the inertial sensor 333, and may determine whether or not the user's receiving a phone call or staring at (or viewing) the display 320 in that posture.
The processor 310 may determine the movement of the electronic device 101 by using the inertial sensor 333. The processor 310 may extract sensor data (for example, acceleration value and/or gravity value) provided by the acceleration sensor of the inertial sensor 333, and may determine the movement of the electronic device 101, based on the extracted sensor data. The processor 310 may extract sensor data (e.g., angular velocity value) provided by the gyroscope of the inertial sensor 333, and may determine the movement of the electronic device 101, based on the extracted sensor data.
The processor 310 may measure a change in angle resulting from the movement of the electronic device 101 through the inertial sensor 333. The processor 310 may calculate the vector sum and variance of the acceleration sensor of the inertial sensor 333, thereby calculating a change in angle of the electronic device 101. The processor 310 may integrate the rate of rotation of the electronic device 101 measured through the gyroscope of the inertial sensor 333, thereby measuring a change in angle of the electronic device 101.
The processor 310 may identify whether or not the determined movement of the electronic device 101 is included in a preconfigured threshold range. The processor 310 may identify whether or not the absolute value of the amount of change in the angle of the electronic device 101 is equal to/less than 10°. The processor 310 may determine that the movement of the electronic device 101 has slowed down if the movement of the electronic device 101 is included in the preconfigured threshold range and, in this case, may determine that the user is using the electronic device 101 while staring at the display 320 of the electronic device 101.
The processor 310 may determine the user's intent to use the display 320, based on the determined posture of the user and the determined movement of the electronic device 101.
The processor 310 may determine that the user has an intent to use the display 320, if the user is staring at the display 320 of the electronic device 101, and if the movement of the electronic device 101 is occurring within the preconfigured threshold range, for example.
The processor 310 may determine that the user has no intent to use the display 320, if the user is not staring at the display 320 (for example, if the user is receiving a phone call). The processor 310 may determine that the user has no intent to use the display 320, if the movement of the electronic device 101 exceeds the preconfigured threshold range (e.g., if the absolute value of the amount of change in the angle of the electronic device 101 exceeds 10°).
The processor 310 may determine a configuration value of the proximity sensor 331 for determining whether or not an object approaches, based on the determined user's intent to user the display 320. The processor 310 may configure a reference value to be used by the proximity sensor 331 to recognize an approaching object, based on the determined user's intent to user the display 320. The configuration value may include a configuration value regarding a recognition time during which an object is recognized, in order to determine whether or not an object approaches. The configuration value may include a configuration value regarding the number of sampled to be recognized to determine whether or not an object approaches.
The processor 310 may determine at least one of the recognition time or the number of sampled to be recognized, which is to be used by the proximity sensor 331 to determine whether or not an object approaches, based on the determined user's intent.
The recognition time of the proximity sensor 331 may refer to a time during which the proximity sensor 331 can acquire a result value after an external object has approached. If a long recognition time is configured, it is impossible to quickly determine whether or not an external object approaches, and no response is made to a temporary approach (for example, a gesture of lowering the status bar), thereby filtering out temporary approaches. In such a case, in which a temporary approach is not recognized by the proximity sensor 331, the display 320 may not be turned off through an auto screen off function. If a short recognition time is configured, a quick determination regarding whether or not an approach occurs may be made, thereby turning off the display 320 through the auto screen off function before the user makes an inadvertent touch input (for example, a touch input by his/her ears or cheeks).
The number of samples to be recognized by the proximity sensor 331 may refer to the number of sampled to be identified to determine whether or not an external object approaches. If a large number of samples to be recognized is configured, a long time (that is, a recognition time) is necessary to determine whether or not an external object approaches, and thus it is impossible to quickly determine whether or not an external object approaches, but no response is made to a temporary approach (e.g., a gesture of lowering the status bar), thereby filtering out temporary approaches. If a small number of samples to be recognized by the proximity sensor 331 is configured, a quick determination regarding whether or not an approach occurs may be made, thereby instantly turning off the display 320 in response to an approaching external object.
Table 2, below, gives an example of configuring the recognition time or the number of samples to be recognized by the proximity sensor 331 according to the user's intent to use the display 320. Values enumerated in Table 2 below are exemplary, and may be variously configured.
If it is determined that the user has an intent to use the display 320, the processor 310 may configure a relatively long recognition time (e.g., 500 ms) in order to filter out the user's temporary approaches. If it is determined that the user has an intent to use the display 320, the processor 310 may configure a relatively large number of samples (e.g., 50 samples) to be recognized.
If it is determined that the user has no intent to use the display 320, the processor 310 may configure a relatively short recognition time (e.g., 10 ms) in order to instantly turn off the display 320 in response to the user's approach. If it is determined that the user has no intent to use the display 320, the processor 310 may configure a relatively small number of samples (e.g., 10 samples) to be recognized.
If the proximity sensor 331 is an optical proximity sensor 331, the amount of light to be used by the proximity sensor 331 to recognize an approach may be determined based on the user's intent to use the display 320. If it is determined that the user has an intent to use the display 320, the processor 310 may configure a high threshold value regarding the amount of light to be used by the proximity sensor 331 to recognize an approach, thereby processing confirmed approaches only, and filtering out temporary approaches. If it is determined that the user has no intent to use the display 320, the processor 310 may configure a low threshold value regarding the amount of light to be used by the proximity sensor 331 to recognize an approach, thereby improving the response rate for determining whether or not an approach occurs.
The processor 310 may determine, based on the user's intent to use the display 320, whether to use all recognized samples or to select and use only some of the samples. If it is determined that the user has no intent to use the display 320, the processor 310 may increase the approach recognition rate in order to identify all samples to be recognized. If it is determined that the user has an intent to use the display 320, the processor 310 may select and identify only specific samples, thereby filtering out temporary approaches.
The electronic device 101 may include a housing 350, a display 320, and a proximity sensor 331 or an inertial sensor.
The housing 350 may refer to an external part surrounding the electronic device 101. The housing 350 may include a front plate 410 facing in a first direction, a rear plate facing in a second direction opposite to the first direction, and a side member surrounding a space between the front plate 410 and the rear plate.
The display 320 may be disposed on at least a part of the front plate 410 of the housing 350, and the display 320 may be disposed on at least a part of the front plate 410 to be visible to the outside. Inputs by various external objects (for example, the user's hands) on the display 320 may be received.
In line with an increasing number of electronic devices 101 designed such that the display 320 occupies a large area on the front plate 410 (for example, bezel-less display 320), the region on the front plate 410, in which various components are to be disposed, decreases. As a result of the decreasing area of the region in which components are to be disposed, components increasingly tend to be disposed between the display 320 and the rear plate. The proximity sensor 331 may be disposed between the display 320 and the rear plate. The proximity sensor 331 may include a light emitter 331a and a light receiver 331b. In general, the proximity sensor 331 may not be recognized by human eyes in an environment in which the display operates. When the proximity sensor 331 is driven, light emitted through the light emitter 331a may be displayed.
The processor 310 may control operations of the display 320 by using the proximity sensor 331 while a specific application (e.g., a telephone call application or a voice message application) is executed. The processor 310 may turn off the display 320 if an approaching external object is sensed through the proximity sensor 331 (for example, if the electronic device 101 is next to the user's ears or cheeks) while a telephone call application is executed. The processor 310 may also turn on the display 320 if no approaching external object is sensed through the proximity sensor 331 (e.g., if the electronic device 101 moves away from the user) while the telephone call application is executed. The display 320 auto screen off function may prevent the occurrence of erroneous operations due to touch inputs by the user's face or ears while a specific application is executed.
If the proximity sensor 331 is disposed below the display 320 (e.g., disposed on the rear surface of the display) in order to expand the display 320 region, the display 320 screen may be turned off by the user's hand approaching the proximity sensor 331 for a touch input on the screen, not by the user's ears or cheeks approaching the proximity sensor 331 according to the user's posture during a phone call.
Referring to
In such a case, the user may not make a touch input as desired, due to the display 320 auto screen off function.
Referring to
The user may not touch the keypad as desired, because the screen of the display 320 is turned off.
The processor 310 of the electronic device 101 may determine the user's intent to use the display 320, and may determine a configuration value of the proximity sensor 331 based on the determined user's intent to use the display 320. The processor 310 may configure each reference value to be used by the proximity sensor 331 to recognize an object, based on the determined user's intent to use the display 320.
Referring to the flowchart 600, a processor 310 of an electronic device 101 identifies whether or not a specific application that uses a function of a proximity sensor 331 has been activated, in step 610. The specific application that uses a function of the proximity sensor 331 may include, for example, a telephone speech application or a voice message application.
The processor 310 determines the user's posture through an inertial sensor 333, in response to activation of the specific application that uses a function of the proximity sensor 331, in step 620. For example, the processor 310 may determine whether the user is in a posture of receiving a telephone call or staring at (or viewing) a display 320 of the electronic device 101.
The processor 310 determine a movement of the electronic device 101 through the inertial sensor 333 in step 630. For example, the processor 310 may determine whether or not the movement of the electronic device 101 occurs within a preconfigured threshold range.
The processor 310 determines the user's intent to use the display 320, based on the determined user's posture and the determined movement of the electronic device 101, in step 640.
The processor 310 determines a configuration value to be used by the proximity sensor 331 to determine whether or not an object approaches, based on the determined use's intent to use the display 320, in step 650. The processor 310 may determine at least one of a recognition time during which the proximity sensor 331 is to determine whether or not an object approaches, or the number of samples to be recognized thereby, based on the determined use's intent.
Referring to the flowchart 700, a processor 310 identifies whether or not a specification application that uses a function of a proximity sensor 331 has been activated, in step 701.
The processor 310 determines the user's posture through an inertial sensor 333, in response to activation of the specification application that uses a function of the proximity sensor 331, in step 703.
The processor 310 determines whether or not the determined user's posture corresponds to a preconfigured posture, in step 705. The preconfigured posture may be a posture in which the user is staring at a display 320. The posture in which the user is staring at the display 320 may include a posture in which the user views the display 320 of the electronic device 101 in an upright position, a posture in which the use views the same in a lying position, or a position in which the user views the same in a sideways lying position.
If it is determined in step 705 that the user's posture corresponds to the preconfigured posture, the processor 310 proceeds to step 707 and determines the movement of the electronic device 101 through the inertial sensor 333. The processor 310 may measure a change in the angle of the electronic device 101 through the inertial sensor 333.
If it is determined in step 705 that the user's posture does not correspond to the preconfigured posture, the processor 310 proceeds to step 715 and determines that the user has no intent to use the display 320 of the electronic device 101.
The processor 310 identifies whether or not the movement of the electronic device 101 has occurred within a preconfigured threshold range in step 709. The processor 310 may identify whether or not the angle of the electronic device 101 has been changed within a preconfigured threshold angle range.
If it is determined in step 709 that the movement of the electronic device 101 has occurred within the preconfigured threshold range, the processor 310 proceeds to step 711 and determines that the user has an intent to use the display 320 of the electronic device 101. The processor 310 determines, in step 713, that the recognition time of the proximity sensor 331 is a first time, or that the number of samples to be recognized by the proximity sensor 331 is a first number. If a second time shorter than the first time has been configured as a default value of the recognition time of the proximity sensor 331, the processor 310 may change/configure the recognition time of the proximity sensor 331 from the second time to the determined first time.
If it is determined in step 709 that the movement of the electronic device 101 has occurred outside the preconfigured threshold range, the processor 310 proceeds to step 715 and determines that the user has no intent to use the display 320 of the electronic device 101. The processor 310 determines, in step 717, that the recognition time of the proximity sensor 331 is a second time, or that the number of samples to be recognized by the proximity sensor 331 is a second number. The second time may be shorter than the first time, and the second number may be smaller than the first number.
If it is determined that the user has an intent to use the display 320 of the electronic device 101, the processor 310 of the electronic device 101 may determine that the recognition time of a proximity sensor 331 is a first time, which is relatively long, or that the number of samples to be recognized is a first number, which is relatively large. The proximity sensor 331 may filter out temporary approaches of the user such that they are not sensed.
While a telephone call application that uses a function of the proximity sensor 331 is executed, the user may perform an operation of lowering a status bar 820 through a drag input 810 that moves from up to down. A temporary approach occurs as a result of the drag input 810, and the proximity sensor 331, which has a first time configured as the recognition time, may thus fail to sense the drag input 810. In this case, no approach resulting from the drag input 810 is sensed, and the display 320 may accordingly not be turned off. The user may perform an operation following the drag input without turning off the display 320. For example, the user may drag the status bar 820 downwards without turning off the display 320.
Referring to
The processor 310 may determine whether or not an approach occurs, based on a determine recognition criterion.
Even if it has been determined that the recognition time of the proximity sensor 331 is the first time, an approach may be recognized beyond the determined first time. When an approaching external object is sensed based on the determined recognition time, the processor 310 may perform an operation of turning off the display 320. Alternatively, instead of instantly turning off the display 320, the processor 310 may display a user interface (UI) 920 for locking a touch input and unlocking the touch input.
When locking a touch input, the processor 310 may be prevented from receiving any touch input from the user, until a separate user input for unlocking the touch input is received. The processor 310 may ignore any user input while the user interface 920 for locking a touch input and unlocking the same is displayed.
If a preconfigured user input for unlocking the touch input is received through the user interface 920 for unlocking the touch input, the processor 310 may unlock the touch input and end the display of the user interface 920.
The preconfigured user input for unlocking the touch input may include a drag input in a specific position inside the user interface 920, or a touch input maintained for a specific time in the specific position. If a drag input is received in a drag region 925 inside the user interface 920 for unlocking the touch input, the processor 310 may unlock the touch input and end the display of the interface. If a specific region is touched for four seconds or longer, the processor 310 may unlock the touch input and end the display of the interface.
If an object (e.g., the user's hand 910) recognized through the proximity sensor 331 is no longer in proximity, the processor 310 may unlock the touch input and end the display of the user interface 920.
The user interface 920 for locking the touch input and unlocking the same may also be displayed when a continuous approach not intended by the user is sensed, in addition to filtering out temporary approaches through the proximity sensor 331, such that any touch input not intended by the user is prevented from occurring. Even if the user interface 920 is displayed after the touch input is locked, the user may easily unlock the touch input through a preconfigured user input.
Referring to flowchart 1000, a processor 310 determines the user's intent to use the display 320, based on the user's posture and the movement of the electronic device 101, in step 1001. For example, the processor 310 may determine the user's posture through an inertial sensor 333, in response to activation of a specific application that uses a function of a proximity sensor 331, and may determine the movement of the electronic device 101 through the inertial sensor 333.
If it is determined in step 1003 that the user has an intent to use the display 320, the processor 310 may proceed to step 1005 and determine that the recognition time of the proximity sensor 331 is a first time, or that the number of samples to be recognized is a first number.
The processor 310 identifies, in step 1009, whether or not an approaching external object is recognized, based on a determined recognition criterion (for example, a recognition time or a number of samples to be recognized). If an approaching external object (for example, the user's hand) is recognized based on the determined recognition criterion, the processor 310 proceeds to step 1011 and locks the touch input. If no approaching external object is recognized based on the determined recognition criterion, the processor 310 proceeds to step 1019 and maintains the display 320 to be turned on.
The processor 310 may display a user interface (for example, user interface 920 in
The processor 310 identifies, in step 1015, whether or not a preconfigured user input for unlocking the touch input is received. The preconfigured user input for unlocking the touch input may include, for example, a drag input in a specific position inside the user interface, or a touch input maintained for a specific time in the specific position.
If the preconfigured user input for unlocking the touch input is received, the processor 310 proceeds to step 1017 and unlocks the touch input, and ends the display of the UI. The processor 310 maintains the display 320 to be turned on in step 1019.
If no preconfigured user input for unlocking the touch input is received, the processor 310 proceeds back to step 1011 and maintains the touch input to be locked.
If it is determined in step 1003 that the user has no intent to use the display 320, the processor 310 proceeds to step 1007 and determines that the recognition time of the proximity sensor 331 is a second time, or that the number of samples to be recognized is a second number.
The processor 310 identifies, in step 1021, whether or not an approaching external object is recognized, based on a determined configuration value (for example, a recognition time or a number of samples to be recognized).
If an approaching external object (for example, the user's hand) is recognized based on the determined configuration value, the processor 310 proceeds to step 1023 and turns off the display 320.
If no approaching external object is recognized based on the determined configuration value, the processor 310 proceeds to step 1019 and maintains the display 320 to be turned on.
