CROSS REFERENCE TO RELATED APPLICATIONS

This application is a National Phase Entry of PCT International Application No. PCT/KR2020/002319, which was filed on Feb. 18, 2020, and claims a priority to Korean Patent Application No. 10-2019-0019487, which was filed on Feb. 19, 2019, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

Certain embodiments disclose an apparatus and method that provide feedback for guiding a user input (e.g., fingerprint input) in an electronic device.

BACKGROUND ART

Recently, electronic devices have advanced and developed to encompass a diversity of functions including those of traditional multimedia players, and now include composite functions such as capturing pictures or videos, playing music or video files, playing games, receiving broadcasts, or making calls. These multi-function electronic devices may include one or more displays, for displaying screens related to executing diverse applications and functions.

Because of the diversity of functions executable by these electronic devices, information related to a user's privacy and/or security may be stored in the electronic device. For example, the device may store not only contact information, call history, and/or messages, but also sensitive information such as private user information (e.g., personal information), such as locations (e.g., addresses), memos and notes, photographs, or financial transactions and accounts, etc. Accordingly, the ability of the electronic device to perform various functions in view of composite functionality may also leave it vulnerable to security issues such as exposure and leakage of the user's private information.

Recently, electronic devices have implemented security functions to protect users' private information, including user-specific authentication systems for individual electronic devices. These may include fingerprint recognition authentication. For example, fingerprint recognition authentication may be implemented in a small electronic device and is advantageous with regard to security, and thus has seen widespread implementation.

The display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.

The audio module 170 may convert a sound into an electrical signal and vice versa, and may obtain the sound via the input device 150, or output the sound via the sound output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., over wires) or wirelessly coupled with the electronic device 101.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and generate an electrical signal or data value corresponding to the detected state, and may include a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The battery 189 may supply power to at least one component of the electronic device 101, and may include 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. 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., a LAN or a 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 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 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. Another component (e.g., an 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)).

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.

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, as at least part of a reply to the request. To that end, a cloud, distributed, or client-server computing technology may be used, for example.

The electronic device 101 according to embodiments may be one of various types of electronic devices, such as a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. However, the electronic devices are not limited to those described above.

According to an embodiment, the electronic device 101 may further include a sensor module not shown (e.g., sensor module 176 in FIG. 1), for example, at least one of a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an IR sensor, a biometric sensor, a temperature sensor, or a humidity sensor.

According to certain embodiments, the display 220 of the electronic device 101 may be implemented in a design in which the area occupying the first surface is increased (e.g., bezel-less display), and various components disposed on the first surface (e.g., first sensor module 240 and/or second sensor module 250) may be disposed between the display 220 and the second surface or within the display 220. For example, the proximity sensor and/or the illuminance sensor may be disposed as an under-display sensor structure between the display 220 and the second surface (or, at the lower portion of the display 220 (e.g., under panel)). As another example, the proximity sensor and/or the illuminance sensor may be formed inside the display 220 by being integrally formed with the display 220 in an in-display sensor structure (e.g., on cell touch AMOLED (OCTA) structure).

According to certain embodiments, the electronic device 101 may provide a function of fingerprint recognition on the display 220 (e.g., fingerprint on display (FOD) or in-display fingerprint) (hereinafter, referred to as “display fingerprint recognition”). For example, as illustrated in FIG. 2, the electronic device 101 may include a fingerprint recognition sensor 200 (e.g., display fingerprint recognition sensor) at a portion between the display 220 and the second surface (or, lower portion of the display 220 (e.g., under panel)) (or, space formed by the housing 210). For example, the fingerprint recognition sensor 200 may be disposed, in an under-display sensor structure, at a portion between the display 220 placed on the front surface (e.g., first surface) of the electronic device 101 and the second surface (or, at the lower portion of the display 220 (e.g., under panel)). As another example, the fingerprint recognition sensor 200 may be formed inside the display 220 by being integrally formed with the display 220 in an in-display sensor structure (e.g., OCTA structure).

In a certain embodiment (not shown), the fingerprint recognition sensor 200 may be disposed on a separate button (e.g., physical home button) at the lower end of the display 220 placed on the first surface of the housing 210 and/or on a separate button in some region of the second surface. In a certain embodiment (not shown), the electronic device 101 may be implemented to further include a fingerprint recognition sensor in the form of a button together with the display fingerprint recognition sensor. In a certain embodiment (not shown), the fingerprint recognition sensor 200 may be implemented with a full-area fingerprint recognition sensor configured to have an area corresponding to the entire surface (e.g., full area) of the display 220 (e.g., capable of supporting fingerprint recognition through the entire surface of the display 220).

According to an embodiment, the electronic device 101 may provide display fingerprint recognition based on the fingerprint recognition sensor 200. In an embodiment, the display fingerprint recognition may be implemented such that the fingerprint recognition sensor 200 is disposed under the display 220 (e.g., under panel), so that the fingerprint recognition sensor 200 is not exposed to the outside. For example, the electronic device 101 may embed the fingerprint recognition sensor 200 under the display (e.g., lower part of the display panel), and may recognize a fingerprint in contact with (or, touched on) the front surface of the display (e.g., display surface (or screen)).

According to an embodiment, the fingerprint recognition sensor 200 may have a configuration corresponding to an optical method, an ultrasonic method, and/or a capacitive method (or semiconductor method). The optical method may be a method of acquiring a fingerprint image (or image) reflected by visible light. The ultrasound method may be a method of acquiring a fingerprint image by using an ultrasound examination principle. The capacitive method may be a method of acquiring a fingerprint image by using a difference in capacitance. For example, the optical method may be a method of illuminating the platen with light and recognizing a reflected fingerprint image according to the shape of a fingertip placed on the platen. For example, the semiconductor method may be a method using electrical conduction characteristics of the skin, which reads the special shape of the fingerprint in contact with the chip surface as an electrical signal when a fingertip is in direct contact with the chip surface, and may be a method using biological characteristics. According to an embodiment, the fingerprint recognition sensor 200 may be configured as a touch sensor type. The touch sensor may arrange electrodes at intervals smaller than the size and interval of valleys and ridges of the fingerprint.

According to an embodiment, the fingerprint recognition sensor 200 may be implemented as a swipe type or a fixed area type. For example, the swipe type is a method of dragging a finger at the location of the fingerprint recognition sensor 200, where the dragged finger (i.e., fingerprint) can be sequentially recognized by one-dimensionally or linearly arranged sensor electrodes and then a two-dimensional fingerprint image can be synthesized through post-processing. For example, the fixed area type may be a method of obtaining a two-dimensional fingerprint image while a finger is being placed on the sensor arranged in two dimensions. According to an embodiment, in the touch sensor for recognizing a fingerprint, electrodes may be disposed in one dimension or two dimensions.

According to certain embodiments of the disclosure, to guide the fingerprint input position (or, position where the fingerprint recognition sensor 200 is disposed) of the fingerprint recognition sensor 200 (e.g., display fingerprint recognition sensor), the display 220 may provide (or display) an indicating object (e.g., fingerprint image object and/or guide text) through a corresponding region in which the fingerprint recognition sensor 200 is disposed on the display 220. For example, in a situation where fingerprint input is requested, the processor 120 may display an indicating object based on a region for guiding fingerprint input to the user (e.g., region in which the fingerprint recognition sensor 200 is disposed). According to an embodiment, when providing the indicating object, the processor 120 may activate a function of receiving a touch input in the region where the fingerprint recognition sensor 200 is disposed and the surrounding region thereof on the display 220, and/or may deactivate the touch input reception function in the remaining region except for the region for activating the touch input function (e.g., region where the fingerprint recognition sensor 200 is disposed and the surrounding region thereof).

FIGS. 3A and 3B are diagrams illustrating examples of a usage scenario of the fingerprint recognition sensor in the electronic device 101 according to certain embodiments of the disclosure.

According to an embodiment, when the user performs user authentication based on fingerprint authentication (e.g., fingerprint mode), as shown by operation 301, an indicating object 300 (e.g., a fingerprint image object and/or guide text object) for prompting (or guiding) input of a fingerprint for authentication and recognition may be provided in a region (e.g., region in which the fingerprint recognition sensor 220 is disposed) on the lock screen 310 being displayed. According to an embodiment, the user may perform fingerprint recognition by touching a finger to the indicating object 300 on the screen 310 (e.g., lock screen) on which the indicating object 300 for fingerprint recognition is displayed, through the display 220 of the electronic device 101. In an embodiment, fingerprint recognition may be performed based on a swipe type or a fixed area type in the fingerprint recognition region corresponding to the indicating object 300. In an embodiment, fingerprint recognition on the display 220 may be performed when a long touch is made on the fingerprint recognition region of the display 220 (e.g., on the region of the indicating object 300).

According to an embodiment, when a touch input is detected (e.g., detection of a measurement value provided from the touch sensor) through the fingerprint recognition region corresponding to the indicating object 300, the electronic device 101 may obtain a fingerprint image through the fingerprint recognition sensor 200 and analyze the obtained fingerprint image.

According to an embodiment, upon determining that the fingerprint image is a complete image (e.g., fingerprint image when the user fully performs fingerprint recognition through the fingerprint recognition sensor 200), and properly authenticated according to a fingerprint image analysis result, as shown by operation 303, the electronic device 101 may process an operation related to unlocking the lock screen through fingerprint recognition. For example, the electronic device 101 may perform authentication based on the fingerprint image obtained through the fingerprint recognition sensor 200, and may display a screen 320 (e.g., home screen or application execution screen) from which the lock screen is released based on the authentication result (e.g., successful authentication) according to fingerprint recognition. According to an embodiment, the indicating object 300 may be displayed, for example, while the fingerprint mode (or, fingerprint recognition function) is activated, and may be not displayed while the fingerprint mode is deactivated.

With reference to FIG. 3B, FIG. 3B may show an example of an operation when the user attempts to perform account authentication (e.g., log-in) at a specific website through fingerprint recognition. FIG. 3B may be a case in which the fingerprint recognition region, that is, the fingerprint recognition sensor 200 is embedded in the display 220.

According to an embodiment, when the user performs account authentication using fingerprint authentication (e.g., fingerprint mode), as shown by operation 311, an indicating object 300 (e.g., fingerprint image object and/or guide text object) for prompting (or guiding) input of a fingerprint for authentication and recognition may be provided in a region (e.g., region in which the fingerprint recognition sensor 220 is disposed) on the website screen 330 being displayed. According to an embodiment, the user may perform fingerprint recognition through the display 220 of the electronic device 101 by touching a finger on the indicating object 300 on the screen 330 (e.g., login screen) on which the indicating object 300 for fingerprint recognition is displayed. In an embodiment, fingerprint recognition may be performed based on a swipe type or a fixed area type in the fingerprint recognition region corresponding to the indicating object 300. In an embodiment, fingerprint recognition on the display 220 may be performed when a long touch is made on the fingerprint recognition region (e.g., on the region of the indicating object 300) of the display 220.

According to an embodiment, upon determining that the fingerprint image is a complete image (e.g., fingerprint image when the user fully performs fingerprint recognition through the fingerprint recognition sensor 200), and the fingerprint is properly authenticated based on the fingerprint image analysis result, as shown by operation 313, the electronic device 101 may process an operation related to performing account authentication (login) on the website through fingerprint recognition. For example, the electronic device 101 may perform authentication based on the fingerprint image obtained through the fingerprint recognition sensor 200, display a related guide screen 340 based on the authentication result according to fingerprint recognition, and log on to the website when authentication is successful. According to an embodiment, the indicating object 300 may be displayed, for example, while the fingerprint mode (or, fingerprint recognition function) is activated, and may be not displayed while the fingerprint mode is deactivated.

According to certain embodiments, in the following description, a fingerprint mode or a fingerprint recognition mode may be used as a term including a fingerprint registration mode and a fingerprint input mode. According to an embodiment, the fingerprint registration mode may be a mode in which a fingerprint is initially registered in the electronic device 101. According to an embodiment, the fingerprint input mode is a mode in which a fingerprint is input to perform a specific function (e.g., unlock function or fingerprint-based user authentication) in a state where a fingerprint has been registered, and the electronic device 101 may compare the input fingerprint with the registered fingerprint and perform a corresponding function according to whether there is a match.

FIGS. 4 and 5 are diagrams for explaining an example of a finger touch for fingerprint recognition in the electronic device 101 according to certain embodiments of the disclosure.

With reference to FIGS. 4 and 5, FIG. 4 shows an example of scanning a fingerprint with a fingertip, and FIG. 5 shows an example of scanning a fingerprint with an entire finger.

According to an embodiment, for fingerprint recognition, the user may perform a fingerprint input using a touch method as shown in FIG. 4 or FIG. 5. According to an embodiment, when scanning a finger to recognize a user's fingerprint, the electronic device 101 may perform a scan based on a fingertip 410 (e.g., finger edge portion) (e.g., touch input with a relatively small area) according to a user input (or touch input) as illustrated in FIG. 4, or may perform a scan with a finger area 420 (e.g., touch input with a relatively large area) according to a user input (or touch input) as illustrated in FIG. 5. According to an embodiment, the user may perform fingerprint input in a swipe type by entering a finger into the region where the fingerprint recognition sensor 200 is located from a certain direction (e.g., entering from a lower portion of the electronic device 101, or entering from a side of the electronic device 101) and swiping the region where the fingerprint recognition sensor 200 is located, or perform fingerprint input in a fixed area type by placing a finger on the region where the fingerprint recognition sensor 200 is located for a preset period of time.

In certain embodiments, while waiting for fingerprint recognition based on the fingerprint recognition sensor 200, the electronic device 101 may not operate with respect to a touch input by the touch sensor. For example, while performing fingerprint sensing in response to a touch input entered by the user on the region where the fingerprint recognition sensor 200 is located, the electronic device 101 may not perform an operation (or function) related to a touch input.

The fingerprint recognition sensor 200 may be mounted inside the display 220 to recognize a fingerprint input from the user. According to an embodiment, the fingerprint recognition sensor 200 may obtain image information (or fingerprint information) of a finger fingerprint indicating a difference in characteristics unique to the user. In an embodiment, the fingerprint recognition sensor 200 may obtain a fingerprint image in various ways, such as an optical method, a semiconductor element method that detects capacitance or electrical conduction, an ultrasonic method, a heat detection method, a non-contact method, or a combination thereof.

According to an embodiment, the processor 120 may detect an occurrence of an event related to fingerprint recognition, and may control (e.g., activation/deactivation control, function control) at least one of the display 220, the touch sensor 610, and/or the fingerprint recognition sensor 200 in response to an event occurrence. For example, in a mode related to fingerprint recognition (e.g., fingerprint recognition mode), the processor 120 may detect a touch input related to the fingerprint recognition region in which the fingerprint recognition sensor 200 is located from the touch sensor 610 and activate the fingerprint recognition sensor 200 based on the touch input.

According to certain embodiments, when detecting an occurrence of an event, the processor 120 may control the display 220 to display a screen related to the event occurrence. For example, the screen related to an event occurrence may include various screens including an indicator (or, indicating object 300) or information related to the event. According to an embodiment, the display 220 may activate the input reception function for receiving a touch input or a proximity input while displaying a screen related to an event occurrence.

According to an embodiment, the processor 120 may control an operation related to providing the function of fingerprint recognition on the display 220 (e.g., fingerprint on display (FOD) or in-display fingerprint) (hereinafter referred to as “display fingerprint recognition”).

According to certain embodiments, when performing the display fingerprint recognition function, the processor 120 may provide a graphical object for a graphical effect based on the region from which the touch region according to a user input is excluded, or may provide a graphical object included in the touch region by moving it. A description will be given of operations of the processor 120 according to certain embodiments with reference to the drawings described later.

According to an embodiment, the processor 120 may include a fingerprint processing module 620 and a function processing module 630.

For example, when performing the display fingerprint recognition function, the function processing module 630 may provide a graphical object for a graphical effect based on the region from which the touch region according to a user input is excluded, or may provide a graphical object included in the touch region by moving it.

In certain embodiments, a fingerprint mode or a fingerprint recognition mode may be used as a term including a fingerprint registration mode and a fingerprint input mode. According to an embodiment, the fingerprint registration mode may be a mode in which a fingerprint is initially registered in the electronic device 101.

According to an embodiment, FIG. 7 may illustrate an example in which the electronic device 101 processes fingerprint recognition through the display fingerprint recognition sensor 200 and provides feedback to the user based on a graphical effect while processing fingerprint recognition.

With reference to FIG. 7, at operation 701, the processor 120 of the electronic device 101 may detect an occurrence of an event. In an embodiment, the event occurrence may include a situation requiring fingerprint authentication, such as, for example, an event entering a fingerprint recognition mode (or, fingerprint mode) operated based on the fingerprint recognition sensor 200. According to an embodiment, the “fingerprint recognition mode” may be used as a term including a fingerprint registration mode and a fingerprint input mode.

According to an embodiment, the fingerprint registration mode may be a mode in which a fingerprint is initially registered in the electronic device 101. According to an embodiment, the fingerprint input mode is a mode in which a fingerprint is input to perform a specific function (e.g., unlock function or fingerprint-based user authentication) in a state where a fingerprint has been registered, and the electronic device 101 may compare the input fingerprint with the registered fingerprint and perform a corresponding function according to whether there is a match. According to an embodiment, for guiding the user to the fingerprint input position (or, position in which the fingerprint recognition sensor 200 is disposed) of the fingerprint recognition sensor 200, the processor 120 may provide an indicating object (e.g., fingerprint image object and/or guide text) through the fingerprint recognition region (or, region of the indicating object 300) in which the fingerprint recognition sensor 200 is disposed on the display 220.

At operation 703, the processor 120 may execute the fingerprint recognition. According to an embodiment, the processor 120 may operate a fingerprint recognition mode. Subsequently, for example, the processor 120 may detect a user's input (e.g., touch input) in the region where the fingerprint recognition sensor 200 is disposed on the display 220, thereby providing a fingerprint as input.

According to an embodiment, when the user touches a finger on the surface of the display 220, that is, on the region where the fingerprint recognition sensor 200 is disposed on the display 220 (e.g., region where the indicating object 300 is provided) to perform fingerprint recognition, the processor 120 may activate the fingerprint recognition mode. According to an embodiment, the user may input a touch on the fingerprint recognition region (or, region of the indicating object 300) (e.g., display 220 in which the fingerprint recognition sensor 200 is embedded). When a user input (e.g., touch input) is detected through the fingerprint recognition region in a state where the fingerprint recognition mode is activated, the processor 120 may identify this as a fingerprint recognition execution request.

At operation 705, the processor 120 may perform image processing on the received fingerprint, in response to receiving the user input on the fingerprint recognition region. According to an embodiment, the processor 120 may detect a user input (e.g., touch) on the fingerprint recognition region through the fingerprint recognition sensor 200, and scan (or, sense) a user's fingerprint through the fingerprint recognition sensor 200 in response to the user input. In an embodiment, the processor 120 may generate a fingerprint image in response to the progress of fingerprint scan.

At operation 707, the processor 120 may provide (e.g., display) a graphical effect while performing image processing. According to an embodiment, the processor 120 may provide a graphical effect in the touch region (e.g., fingerprint recognition region to which the finger contacts the screen) according to the user input during image processing. For example, the graphical effect may be displayed while sensing the user's fingerprint through the fingerprint recognition sensor 200. According to an embodiment, when providing the fingerprint recognition function, the processor 120 may provide a graphical effect for fingerprint recognition to the user while performing image processing by sensing the fingerprint at the time of detecting a user input (or, while recognizing the user's fingerprint). According to an embodiment, the processor 120 may provide interactive feedback on the user's fingerprint input.

In an embodiment, when providing a graphical effect, the processor 120 may exclude the touch region touched according to the user input (e.g., region hidden from the user's view due to a user's finger touch) and provide a graphical effect based on the remaining non-touch region. For example, the processor 120 may provide a graphical object for a graphical effect based on the non-touch region from which the touch region according to a user input is excluded, or may provide a graphical object included in the touch region by moving it.

According to an embodiment, graphical effects may be handled in various ways according to the characteristic (or type) thereof. For example, graphical effects may be provided in various ways based on the characteristics thereof, such as assigning different designated times for individual characteristics of graphical effects, differently operating dynamic images and static images, moving graphical objects, or dividing and moving graphical objects. Certain embodiments are described with reference to the drawings below in connection with providing graphical effects.

At operation 709, the processor 120 may execute a function corresponding to the authentication of the fingerprint. According to an embodiment, the processor 120 may compare the input fingerprint with a registered fingerprint, and determine whether a match exists. If a match exists, the fingerprint is authenticated and a corresponding function may be executed. For example, the processor 120 may process an operation, such as unlocking the lock screen, executing a locked (or secured) application or content, or automatically entering authentication information related to user authentication (e.g., logging in). According to an embodiment, the processor 120 may execute a related function based on the image processing result, or when authentication based on the input fingerprint has failed, it may display a related screen and terminate (e.g., not display, or restore (e.g., restore the moved graphical object to its original position)) the graphical effect.

FIG. 8 is a diagram illustrating an example of a user interface that provides a graphical effect in the electronic device 101 according to certain embodiments.

With reference to FIG. 8, as in illustrative screen 801, the electronic device 101 may provide a screen through the display 220 in a situation requiring fingerprint input, such as, for example, a fingerprint recognition mode (or, fingerprint mode) operating based on the fingerprint recognition sensor 200. For example, as shown by illustrative screen 801, the electronic device 101 may provide a lock screen on the display 220. According to an embodiment, in the electronic device 101, the fingerprint recognition sensor 200 (e.g., display fingerprint recognition sensor) may be disposed under a designated region of the display 220 (e.g., under panel).

According to an embodiment, the display 220 may display an indicating object 300, which is indicates the location of the fingerprint recognition sensor 220 (or, fingerprint recognition region) and thus provides guidance for the input of the user's fingerprint, on a region (e.g., fingerprint recognition region) corresponding to a location of the fingerprint recognition sensor 200. The indicating object 300 may be displayed through a designated region on the display 220 (e.g., function active state) when performing an operation related to user authentication in a state where it is not displayed on the display 220 (e.g., function inactive state).

As in illustrative screen 803, the electronic device 101 may detect a user's touch. According to an embodiment, the user may enter a finger touch based on the fingerprint recognition region indicated by the indicating object 300.

According to an embodiment, the electronic device 101 may provide the visual effect 800 in a specific range (or radius) with respect to the region (e.g., touch region) where a touch is detected in the fingerprint recognition region. In a certain embodiment (not shown), the electronic device 101 may provide the visual effect 800 with respect to at least a portion of the entire area of the display 220 and/or the edge area of the display 220.

According to an embodiment, for example, the visual effect 800 may use various graphical objects (e.g., digital motion graphics and/or composite objects) (e.g., dynamic objects and/or static objects). For example, the electronic device 101 may provide a vivid visual effect 800 based on animated objects (or, video objects or motion objects).

For example, the electronic device 101 may provide a visual effect (e.g., water wave effect, radial effect) such as a moving wave (or, wave occurring on the water surface) with respect to the region where a touch is detected. For instance, when providing a visual effect such as a water wave effect, the electronic device 101 may provide an effect of spreading without a size change (e.g., displayed within a specified range (or boundary)). As another example, the electronic device 101 may provide a shining light effect based on at least a region of the display 220. As another example, the electronic device 101 may provide a dynamic visual effect by repeatedly outputting a static object. As another example, the electronic device 101 may provide a dynamic visual effect by applying a color and/or a highlight to a static object.

As in illustrative screen 807, the electronic device 101 may control function execution based on the completion of fingerprint recognition. According to an embodiment, the electronic device 101 may compare the obtained fingerprint image with the preregistered fingerprint image, execute a corresponding function according to whether there is a match, and display a related screen on the display 220. For example, the electronic device 101 may display a screen after release of the lock screen. As another example, the electronic device 101 may process an operation such as execution of a locked (or secure) application or content, or automatic input (e.g., log-in) of authentication information related to user authentication.

According to an embodiment, when executing a related function based on the result of image processing, as shown by illustrative screen 807, the electronic device 101 may terminate providing (or, may not display) the visual effect 800 (or, graphical effect). According to an embodiment, on a screen not in the fingerprint recognition mode, the electronic device 101 may not display the indicating object 300 in the fingerprint recognition region of the display 220 as shown by illustrative screen 807.

For example, the processor 120 may perform fingerprint recognition in the background.

At operation 903, the processor 120 may identify a region in which a touch is detected (e.g., as a touch region). According to an embodiment, the processor 120 may identify (or calculate) a portion and/or area thereof contacted by a user's finger in the fingerprint recognition region. In an embodiment, a description will be given of an example of identifying a region in which a touch is sensed with reference to the following drawings.

At operation 905, the processor 120 may exclude a region in which a touch is sensed from a designated effect region. According to an embodiment, the processor 120 may exclude the region in which a touch is sensed (e.g., region hidden from the user's view due to user's finger touch) from the designated effect region for displaying graphical effects, and set the remaining non-touch region (e.g., region not hidden from the user's view) as a region for graphical effects.

At operation 907, the processor 120 may display a graphical object based on the non-touch region in the designated effect region, excluding display of the graphical object from the touch region in the designated effect region. According to an embodiment, the processor 120 may display a graphical object and/or a visual effect (or, graphical effect) in the non-touch region, excluding the touch region in which the touch input is detected. Thus, the graphical object is not displayed within an entirety of the designated effect region on the display 220.

As in illustrative screen 1003, the electronic device 101 may detect a user's touch. According to an embodiment, the user may enter a finger touch based on the fingerprint recognition region indicated by the indicating object 300. In an embodiment, the electronic device 101 may detect a user input (e.g., touch) on the fingerprint recognition region based on the touch sensor 610.

According to an embodiment, the electronic device 101 may process fingerprint recognition and touch region calculation in parallel in the background. In a certain embodiment, the electronic device 101 may process the operation of calculating the touch region. For example, the electronic device 101 may be operated to process a function for providing a graphical effect and a fingerprint recognition function in parallel, and/or process a function for providing a graphical effect first and then process the fingerprint recognition function.

According to certain embodiments, the electronic device 101 may exclude the touch region 1050 from the designated effect region 1010 for displaying graphical effects. According to an embodiment, the electronic device 101 may exclude the region 1050 in which a touch is sensed (e.g., region hidden from the user's view due to user's finger touch) from the designated effect region 1010 for displaying graphical effects, and display graphical effects in the remaining region 1020 (e.g., region not hidden from the user's view, or the non-touch region).

As in illustrative screen 1007, the electronic device 101 may provide a visual effect 1000 (or, graphical effect) while scanning a fingerprint (or, performing fingerprint recognition). In an embodiment, the electronic device 101 may provide a visual effect using the graphical object 1000 based on the remaining region 1020 obtained by excluding the region 1050 in which a touch is sensed (e.g., touch region) from the designated effect region 1010 for visual effects.

In an embodiment, the graphical object 1000 may be provided based on a specific range (or, radius) (e.g., range in which the designated effect region 1010 is set). In a certain embodiment (not shown), the electronic device 101 may provide the visual effect 1000 with respect to at least a portion of the entire area of the display 220 and/or the edge area of the display 220. According to an embodiment, for example, the visual effect 1000 may use various graphical objects (e.g., digital motion graphics and/or composite objects) (e.g., dynamic objects and/or static objects). For example, the electronic device 101 may provide a vivid visual effect 1000 based on animated objects (or, video objects or motion objects).

For example, the electronic device 101 may provide a visual effect (e.g., water wave effect, radial effect) such as a moving wave (or, wave occurring on the water surface) with respect to the region where a touch is detected. For instance, when providing a visual effect such as a water wave effect, the electronic device 101 may provide an effect of spreading without a size change (e.g., displayed within a specified range (or boundary) such as an effect region 1010). As another example, the electronic device 101 may provide a shining light effect based on at least a region of the display 220. As another example, the electronic device 101 may provide a dynamic visual effect by repeatedly outputting a static object. As another example, the electronic device 101 may provide a dynamic visual effect by applying a color and/or a highlight to a static object.

FIG. 11 is a diagram illustrating an example of a user interface that provides a graphical effect in the electronic device 101 according to certain embodiments.

With reference to FIG. 11, as in illustrative screen 1101, the electronic device 101 may provide a related screen through the display 220 in a situation requiring fingerprint input, for example, in a fingerprint recognition mode (or, fingerprint mode) operating based on the fingerprint recognition sensor 200. For example, as shown by illustrative screen 1101, the electronic device 101 may provide a lock screen on the display 220. In an embodiment, the display 220 may display an indicating object 300 on a region (e.g., fingerprint recognition region) corresponding to a location of the fingerprint recognition sensor 200. The indicating object 300 may be provided through a designated region on the display 220 (e.g., function active state) when performing an operation related to user authentication in a state where it is not displayed on the display 220 (e.g., function inactive state).

As in illustrative screen 1103, the user may enter a finger touch based on the fingerprint recognition region indicated by the indicating object 300. In an embodiment, the electronic device 101 may detect a user input (e.g., touch) on the fingerprint recognition region based on the touch sensor 610. The electronic device 101 may detect a user input on the fingerprint recognition region through the touch sensor 610, and scan (or, sense) a user's fingerprint through the fingerprint recognition sensor 200 based on the user input. In an embodiment, the electronic device 101 may obtain a fingerprint image according to the progress of fingerprint scanning.

As in illustrative screens 1103 to 1107, the electronic device 101 may provide a visual effect (or, graphical effect) based on a graphical object 1100 while scanning a fingerprint (or, performing fingerprint recognition). According to an embodiment, the electronic device 101 may provide a visual effect in which the graphical object 1100 dynamically changes in size (e.g., expanding in radius) (e.g., within a designated effect region) centered on the region where a touch is detected (e.g., touch region) in the fingerprint recognition region.

According to an embodiment, animated objects (or, video objects, motion objects) may be sequentially displayed by using digital motion graphics and/or composite objects. For example, the electronic device 101 may provide a vivid visual effect (e.g., water wave effect) such as a wave occurring on the water surface, like a first sub-object 1110 of the graphical object 1100 in illustrative screen 1103, a second sub-object 1120 of the graphical object 1100 in illustrative screen 1105, or a third sub-object 1130 of the graphical object 1100 in illustrative screen 1107. In an embodiment, when providing a visual effect such as a water wave effect, the electronic device 101 may provide an effect of spreading without a size change (e.g., displayed within a specified range (or boundary)).

As in illustrative screens 1103 to 1107, the electronic device 101 may detect a region in which a touch is detected (e.g., touch region), and exclude the touched region from display of the designated effect region for visual effects. According to an embodiment, the electronic device 101 may provide a visual effect by using the graphical object 1100 based on the remaining region (e.g., region not hidden from the user's view) obtained by excluding the region in which a touch is sensed (e.g., region hidden from the user's view due to the user's finger touch) from the designated effect region for the graphical effect 1100.

As in illustrative screen 1109, the electronic device 101 may control function execution based on the completion of fingerprint recognition. According to an embodiment, the electronic device 101 may compare the obtained fingerprint image with the preregistered fingerprint image, and once authenticated, execute a corresponding function according to whether there is a match, and display a related screen on the display 220. For example, the electronic device 101 may display a screen from which the lock screen is released. As another example, the electronic device 101 may process an operation such as execution of a locked (or secure) application or content, or automatic input (e.g., log-in) of authentication information related to user authentication. According to an embodiment, when executing a related function based on the result of image processing, as shown by illustrative screen 1109, the electronic device 101 may terminate providing (or, may not display) the visual effect (or, graphical object 1100). According to an embodiment, on a screen not in the fingerprint recognition mode, the electronic device 101 may not display the indicating object 300 in the fingerprint recognition region of the display 220 as shown by illustrative screen 1109.

According to certain embodiments of the disclosure, when fingerprint recognition (or user authentication) is performed by using the display fingerprint recognition sensor 200, a touch input interaction is detected in the area touched by the user's finger, and a graphical element (e.g., graphical object) does not appear in the touched portion (e.g., touch region) and may be displayed in the remaining region except for the touched portion.

According to certain embodiments, the visual effect by a graphical object may be provided, for example, for a specified time (e.g., about 1000 ms). According to an embodiment, the specified time may be set to a time corresponding or close to, for example, the time utilized to recognize and process a user's fingerprint through the fingerprint recognition sensor 200. According to certain embodiments, the type of graphical objects may be provided randomly, or at least one designated graphical object may be provided. For example, the electronic device 101 (or, processor 120) may provide a graphical effect by selecting a graphical object in a random manner based on a method set in the electronic device 101, or selecting a specific graphical object designated by the user.

According to certain embodiments, the color of a graphical object may be automatically set based on, for example, the color of a background screen of a currently displayed screen, or may be provided based on a preset color. For example, the color of a graphical object may be provided by tinting one or more (e.g., two colors) selected through color extraction from the background color of the currently displayed screen. For example, the electronic device 101 (or, processor 120) may extract at least one color from the background color of the screen, tint the at least one extracted color, and set it as the color of a graphical object.

FIG. 12 is a flowchart illustrating an operation method of the electronic device 101 according to certain embodiments. FIG. 13 is a diagram illustrating an example of identifying a region in which a touch is sensed in the electronic device 101 according to certain embodiments.

According to an embodiment, FIGS. 12 and 13 may illustrate an example in which the electronic device 101 identifies a region where a touch is detected (e.g., touch region) in the fingerprint recognition region.

With reference to FIGS. 12 and 13, at operation 1201, the processor 120 of the electronic device 101 may detect a touch in the fingerprint recognition region based on the touch sensor 610. For example, as shown by illustrative screen <1301> of FIG. 13, the user may enter a finger touch based on the fingerprint recognition region 1310 indicated by the indicating object 300.

In an embodiment, the processor 120 may detect a touch in the fingerprint recognition region 1310 based on the touch sensor 610, and internally (or, in the background) perform an operation of scanning (or, sensing) the user's fingerprint through the fingerprint recognition sensor 200 in response to detection of the touch. According to an embodiment, as shown by illustrative screen <1301>, the electronic device 101 may detect a touch according to a touch signal provided (or input) from the touch sensor 610 based on a specific region 1320 (e.g., effect region) of a specified range adjacent to the fingerprint recognition sensor 200.

At operation 1203, the processor 120 may convert a touch signal provided from the touch sensor 610 into digital data. In an embodiment, as shown by illustrative screen <1303> of FIG. 13, the processor 120 may convert the touch signal input from the touch sensor 610 into digital data based on the specific region 1320.

At operation 1205, the processor 120 may extract sampling data. According to an embodiment, based on the converted digital data, the processor 120 may extract data (e.g., sampling data) at a level that can be determined as a user's finger contact (e.g., touch) from the specific region 1320. In an embodiment, as shown by illustrative screen <1305> of FIG. 13, the processor 120 may extract digital data having an intensity (or sensitivity) greater than or equal to a specified reference (e.g., threshold) 1350 from among the digital data of the specific region 1320 as sampling data.

At operation 1207, the processor 120 may convert the sampling data. According to an embodiment, the processor 120 may separate a zone corresponding to the sampling data extracted from the specific region 1320 (e.g., first zone) and a remaining zone (e.g., second zone), and convert the data of the first zone and the second zone into different digital values (e.g., binary values ‘0’ and ‘1’). In an embodiment, as shown by illustrative screen <1307> of FIG. 13, information about the finger contact region (e.g., touch region) may be obtained by setting the first zone corresponding to the extracted sampling data to ‘1’, and setting the second zone corresponding to the remaining region is set to ‘0’.

At operation 1209, the processor 120 may identify the touch region. According to an embodiment, the processor 120 may set (or identify) a touch region where a touch is detected based on the region set to have the digital value ‘1’ within the specific region 1320.

According to certain embodiments, the processor 120 may receive measurement values from the touch sensor 610 and perform a function of determining a touch region. According to an embodiment, when a touch event (e.g., key event function) related to the fingerprint recognition region 1310 is received from the touch sensor 610, the processor 120 may perform a function of determining a touch region and a non-touch region in the specific region 1320. In an embodiment, based on digital data related to a touch event, the processor 120 may identify sampling data having a value (e.g., intensity value) of a preset level or higher (e.g., region recognized as actually having finger contact).

According to an embodiment, when sampling data is not recognized, for example, when all digital values of the sampling data are ‘0’, the processor 120 may provide a visual effect by displaying a graphical object based on the whole of the specific region 1320. According to an embodiment, when at least some of the sampling data is recognized, for example, when at least some digital values of the sampling data are ‘1’, the processor 120 may exclude a region whose digital value is set to ‘1’ (e.g., touch region) from the specific region 1320, and provide a visual effect by displaying a graphical object based on the remaining region (e.g., region whose digital value is set to ‘0’ (e.g., non-touch region)) excluding the touch region.

FIG. 14 is a flowchart illustrating an operation method of the electronic device 101 according to certain embodiments.

According to an embodiment, the electronic device 101 of FIG. 14 processes fingerprint recognition through the display fingerprint recognition sensor 200, identifies a region in which a touch is detected (e.g., touch region) and the direction of the touch (or, touch input direction) while processing fingerprint recognition, does not provide (e.g., display) a graphical effect in the region where the touch is sensed, and provides a graphical effect in the remaining region excluding the region where the touch is detected based on the touch direction.

With reference to FIG. 14, at operation 1401, the processor 120 of the electronic device 101 may detect a touch based on a designated fingerprint recognition region. For example, the processor 120 may display an indicating object 300 on a region of the display 220 corresponding to the location of the fingerprint recognition sensor 200 disposed at the lower end of the display 220. In an embodiment, the user may recognize the fingerprint recognition region indicated by the indicating object 300 and enter a finger touch based on the fingerprint recognition region. According to an embodiment, the processor 120 may detect a touch in the fingerprint recognition region based on the touch sensor 610, and internally (or, in the background) perform an operation of scanning (or, sensing) the user's fingerprint through the fingerprint recognition sensor 200 in response to detection of the touch. For example, the processor 120 may perform fingerprint recognition in the background.

At operation 1403, the processor 120 may identify a region where a touch is detected (e.g., touch region) and a touch direction (e.g., touch input direction). According to an embodiment, the processor 120 may identify (e.g., or calculate) a portion and/or an area thereof touched by a user's finger in the fingerprint recognition region. According to an embodiment, the processor 120 may determine the direction of user's finger contact in the fingerprint recognition region. According to an embodiment, the processor 120 may detect a proximity event in which a user's touch approaches (or hovers) and enters based on the touch sensor 610, and determine a first point at which the user's finger enters (or corresponding to an edge of the display 220) based on the region where the proximity event is detected. In an embodiment, the processor 120 may detect a touch event in which the user's finger is touched after the user's finger enters, and determine a second point corresponding to the tip of the user's finger based on the region where the touch event is detected (e.g., edge portion where the user's fingertip is in contact).

According to an embodiment, the processor 120 may identify the touch direction based on the first point and the second point. For example, the processor 120 may draw a virtual line between the first point and the second point (e.g., connect the first point and the second point with an artificially set line), determine the orientation based on the drawn line, and determine the touch direction based on the determined orientation. In an embodiment, the orientation may be calculated by using a method of 360-degree angle with respect to an artificial line between the first point (e.g., start point) and the second point (e.g., target point). For example, a circle may be divided into 360 equal parts, the angle may be measured while rotating in a clockwise direction (or, counterclockwise direction), and the direction may be determined based on the angle.

At operation 1405, the processor 120 may exclude the touch region from the designated effect region. According to an embodiment, the processor 120 may exclude the region in which a touch is detected (e.g., the region hidden from the user's view due to obscuration by the user's finger touch) from the designated effect region for graphical effects, and set the remaining non-touch region (e.g., the region not hidden from the user's view) as a region for displaying graphical effects.

At operation 1407, the processor 120 may display a graphical object in the remaining non-touch region, excluding the touch region where a touch is detected from the designated effect region, based on the touch direction (or, the touch direction and the touch direction). According to an embodiment, the processor 120 may display a graphical object, a visual effect, or a graphic effect based on the touch direction in the non-touch region, excluding the region in which a touch is detected. Thus, the graphical object and/or effect is not displayed in the entire designated effect region on the display 220.

FIG. 15 is a diagram illustrating an example of a user interface that provides a graphical effect in the electronic device 101 according to certain embodiments.

With reference to FIG. 15, as in illustrative screen 1501, the electronic device 101 may provide a screen through the display 220 in a situation requiring fingerprint input, for example, in a fingerprint recognition mode (or, fingerprint mode) operating based on the fingerprint recognition sensor 200. For example, as shown by illustrative screen 1501, the electronic device 101 may provide a lock screen on the display 220. In an embodiment, the display 220 may display an indicating object 300 on a region (e.g., fingerprint recognition region) corresponding to a location of the fingerprint recognition sensor 200.

As in illustrative screens 1503 or 1505, the user may recognize the fingerprint recognition region indicated by the indicating object 300, and enter a finger touch to the fingerprint recognition region. According to an embodiment, the electronic device 101 may detect a touch in the fingerprint recognition region based on the touch sensor 610.

According to certain embodiments, the electronic device 101 may identify a region in which a touch is detected (e.g., touch region 1550 or 1560) and a touch direction (or, touch input direction indicative of a path) 1520 or 1540, and provide a graphical object 1510 or 1530 based on the touch region 1550 or 1560 and the touch direction 1520 or 1540. According to an embodiment, the electronic device 101 may determine the direction 1520 or 1540 of contact between the touch region 1550 or 1560 and the user's finger in the fingerprint recognition region. In an embodiment, the electronic device 101 may identify the touch direction (or, touch input direction) indicating a rough path from a first point 1521 or 1541 to a second point 1523 or 1543 (e.g., direction 1520 entering the display 220 from bottom to top, direction 1540 entering the display 220 from right to left).

According to certain embodiments, the electronic device 101 may exclude the touch region 1550 or 1560 in which a touch is detected (e.g., the region hidden from the user's view due to user's finger touch) from the effect region for graphical effects, and set the remaining non-touch region (e.g., the region not hidden from the user's view) as a region for displaying graphical effects. According to an embodiment, the electronic device 101 may provide a visual effect by using a graphical object 1510 or 1530 in the remaining non-touch region, excluding the touch region 1550 or 1560 from the effect region based on the touch direction 1520 or 1540 (or, touch region 1550 or 1560 and touch direction 1520 or 1540). According to an embodiment, the electronic device 101 may display a graphical object 1510 or 1540 for a visual effect (or, graphical effect) based on the touch direction 1520 or 1540 in the remaining region except for the touch region 1550 or 1560 in which a touch is detected, resulting in display of the graphical object in less than the entire designated effect region on the display 220.
