Description

Method for providing three-dimensional images and electronic devices supporting the same

[0001] The present disclosure relates to a method for providing a three-dimensional image and an electronic device supporting the same.

[0002] Electronic devices can provide three-dimensional images (e.g., three-dimensional stereoscopic images). For example, the electronic devices can provide three-dimensional images using glasses (e.g., shutter glasses, polarized glasses) or using a glasses-free method.

[0003] The glasses-free method may be a method of implementing a three-dimensional image by using a lenticular lens or parallax barrier placed in front of the display to allow the user's left and right eyes to see different image information.

[0004] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0005] An electronic device including a 3D display utilizing a glasses-free method can obtain the positions of a user's eyes (e.g., the user's left and right eyes) using a sensor (e.g., a sensor for eye tracking). The electronic device can display a 3D image corresponding to the positions of the user's eyes through the 3D display, thereby providing the user with an appropriate 3D image (e.g., a 3D image provided without crosstalk).

[0006] If a user moves while an electronic device is displaying 3D images, the user may leave the area where the 3D images can be displayed (e.g., the viewing zone, described below). In such cases, the user may not receive appropriate 3D images from the electronic device without being aware that he or she has left the area where the 3D images can be displayed. Accordingly, the electronic device needs to provide information on whether the user is in a state where 3D images can be displayed.

[0007] In addition, while an electronic device provides a 3D image through a display, multiple users may be present in an area where the 3D image can be provided through the display. In this case, the electronic device may determine a target user (e.g., a user to whom a 3D image will be provided without crosstalk) among the multiple users and provide a 3D image corresponding to the determined target user. In this case, the electronic device needs to provide information about the target user to the multiple users (e.g., information about which user among the multiple users has been determined to be the target user, and the location of the user determined to be the target user). In addition, after determining the target user, if the target user leaves the area where the 3D image can be provided through the display, the electronic device may determine a new target user from among the remaining users, excluding the user who was determined to be the target user. In this case, the electronic device needs to provide information about the newly determined target user to the remaining users.

[0008] Various embodiments of the present disclosure relate to a method for providing a three-dimensional image and an electronic device supporting the same, which can provide a guide indicating whether a user is in a state in which a 3D image (e.g., an appropriate 3D image) can be provided based on a location of a user (e.g., a target user) obtained using a sensor for eye tracking and an area in which a 3D image can be provided through a display.

[0009] The technical problems to be solved by the present disclosure are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0010] An electronic device according to one embodiment may include a display capable of displaying a 3D image using a glasses-free method, a sensor for eye tracking, at least one processor including a processing circuit, and a memory storing instructions. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to acquire a location of a user based on sensed data acquired through the sensor. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to provide a first guide indicating that the user is in a state in which the 3D image can be provided based on the acquired location of the user being included in a first area in which the 3D image is to be provided when the 3D image is displayed through the display. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to display a 3D image to be provided to the user through the display without crosstalk based on the acquired location, based on the acquired location being included in the first area. The above instructions, when executed individually or collectively by the at least one processor, may cause the electronic device to provide a second guide indicating that the user is in a state in which the 3D image cannot be provided through the display based on the acquired user's location not being included in the first area.

[0011] According to one embodiment, a method for providing a 3D image in an electronic device may include an operation of acquiring a user's location based on sensing data acquired through a sensor for eye tracking. The method may include an operation of providing a first guide indicating that the user is in a state in which the 3D image can be provided based on whether the acquired user's location is included in a first area in which the 3D image is to be provided when the 3D image is displayed using a glasses-free method through a display of the electronic device. The method may include an operation of displaying a 3D image to be provided to the user without crosstalk through the display based on whether the acquired user's location is included in the first area. The method may include an operation of providing a second guide indicating that the user is in a state in which the 3D image cannot be provided through the display based on whether the acquired user's location is not included in the first area.

[0012] In one embodiment, a non-transitory computer-readable storage medium having recorded thereon computer-executable instructions, wherein the computer-executable instructions, when individually or collectively executed by at least one processor, may cause an electronic device to acquire a location of a user based on sensed data acquired through a sensor for eye tracking. The computer-executable instructions, when individually or collectively executed by at least one processor, may cause the electronic device to provide a first guide indicating that the user is in a state in which the 3D image can be provided based on the acquired location of the user being included in a first area in which the 3D image is to be provided when the 3D image is displayed using a glasses-free manner through a display of the electronic device. The computer-executable instructions, when individually or collectively executed by at least one processor, may cause the electronic device to display a 3D image to be provided to the user through the display without crosstalk based on the acquired location, based on the acquired location being included in the first area. The computer-executable instructions, when executed individually or collectively by at least one processor, may cause the electronic device to provide a second guide indicating that the user is in a state in which the 3D image cannot be provided through the display based on the acquired user's location not being included in the first area.

[0037] FIG. 1 is a block diagram of an electronic device (101) within a network environment (100), according to one embodiment.

[0038] Referring to FIG. 1, in a network environment (100), an electronic device (101) may communicate with an electronic device (102) via a first network (198) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (104) or a server (108) via a second network (199) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (101) may communicate with the electronic device (104) via the server (108). According to one embodiment, the electronic device (101) may include a processor (120), a memory (130), an input module (150), an audio output module (155), a display module (160), an audio module (170), a sensor module (176), an interface (177), a connection terminal (178), a haptic module (179), a camera module (180), a power management module (188), a battery (189), a communication module (190), a subscriber identification module (196), or an antenna module (197). In some embodiments, the electronic device (101) may omit at least one of these components (e.g., the connection terminal (178)), or may have one or more other components added. In some embodiments, some of these components (e.g., the sensor module (176), the camera module (180), or the antenna module (197)) may be integrated into one component (e.g., the display module (160)).

[0039] The processor (120) may, for example, execute software (e.g., a program (140)) to control at least one other component (e.g., a hardware or software component) of the electronic device (101) connected to the processor (120) and perform various data processing or calculations. According to one embodiment, as at least a part of the data processing or calculations, the processor (120) may store commands or data received from other components (e.g., a sensor module (176) or a communication module (190)) in a volatile memory (132), process the commands or data stored in the volatile memory (132), and store result data in a non-volatile memory (134).

For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0040] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0046] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0047] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0048] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)). In one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0053] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0054] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one 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 module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0055] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0056] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0057] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0058] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0059] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device.

[0066] FIG. 2 is a block diagram of an electronic device (201) according to one embodiment.

[0067] Referring to FIG. 2, in one embodiment, an electronic device (201) may be included in the electronic device (101) of FIG. 1.

[0068] In one embodiment, the electronic device (201) may include communication circuitry (210), a display (220), a sensor (230), memory (240), and / or a processor (250).

[0069] In one embodiment, the communication circuit (210) may be included in the communication module (190) of FIG. 1.

[0070] In one embodiment, the display (220) may be included in the display module (160) of FIG. 1.

[0071] In one embodiment, the display (220) may be a display capable of displaying three-dimensional (3D) images using a glasses-free method.

[0072] In one embodiment, the display (220) may be a display capable of displaying a two-dimensional (hereinafter also referred to as “2D”) and / or three-dimensional (hereinafter also referred to as “3D”) screen using a glasses-free method.

[0073] In one embodiment, the display (220) may be a light field display. For example, the display (220) may display a 3D screen by generating a light field expressed as a vector distribution of light (e.g., intensity and direction of light) in space by a flat display and optical elements.

[0074] In one embodiment, the display (220) may be a display that includes a lenticular lens (also referred to as a “lenticular screen” or “lenticular sheet”) or a parallax barrier.

[0075] In one embodiment, the display (220) may be configured to display a 3D screen using a lenticular lens disposed on the display (220) (e.g., disposed on or attached to the front of the display panel). For example, the display (220) may separate left and right binocular screens (e.g., left and right binocular images) using the lenticular lens. The left and right screens separated by the lenticular lens may be incident on the left and right eyes of the user, respectively, to provide a 3D screen.

[0076] In one embodiment, the display (220) may be configured to display a 3D image using a parallax barrier disposed on the display (220). For example, the display (220) may display a 3D image using an optical configuration (e.g., an optical plate) in which barriers and apertures are disposed at regular intervals.

[0077] However, the display (220) may display a three-dimensional screen using a glasses-free method, but is not limited to the examples described above. For example, the display (220) may be implemented using a volumetric display method that creates a three-dimensional image in a physical three-dimensional space using voxels (Voxels: Volumetric pixels), which are pixels in space.

[0078] In one embodiment, the display (220) may be a display capable of simultaneously displaying a 2D screen and a 3D screen. For example, the display (220) may be a display capable of displaying a portion of the screen in 2D and another portion of the screen in 3D. For example, the display may be capable of simultaneously displaying a 2D screen and a 3D screen such that at least a portion of the 2D screen and at least a portion of the 3D screen overlap.

[0079] In one embodiment, the sensor (230) may be included in the sensor module (176) of FIG. 1.

[0080] In one embodiment, the sensor (230) may include a sensor for eye tracking (hereinafter also referred to as an “ET sensor”).

[0081] In one embodiment, the ET sensor may include an infrared depth sensor (or infrared camera) and an infrared (or visible light) eye tracking camera. However, the ET sensor is not limited to the examples described above and may include any sensor capable of tracking the position of the user's eyes. For example, the ET sensor may include an RGB camera.

[0082] In one embodiment, the ET sensor may be an under display camera (UDC) camera positioned under the display.

[0083] In one embodiment, the ET sensor may be configured to obtain (e.g., calculate) (or track) the positions of the user's eyes (e.g., the positions of the user's eyes relative to the position of the electronic device (201)) using sensing data (e.g., depth information or images) obtained through the ET sensor. For example, the ET sensor may be configured to obtain the distance between the user's eyes and the electronic device (201) (e.g., the display (220)) and the direction between the electronic device (201) and the user using information or images obtained through the ET sensor.

[0084] In one embodiment, the ET sensor may include multiple ET sensors. For example, the electronic device may include multiple ET sensors to acquire the user's location within a wider range (e.g., a wider field of view).

[0085] In one embodiment, the sensor (230) may include a sensor (or camera) (hereinafter also referred to as a “gesture sensor”) for recognizing a user’s gesture (e.g., a hand gesture).

[0086] In one embodiment, the memory (240) may be included in the memory (130) of FIG. 1.

[0087] In one embodiment, the memory (240) may store information necessary to perform an operation to provide a 3D image.

[0088] In one embodiment, the memory (240) may store instructions that, when executed individually or collectively by at least one processor (250) included in the electronic device (201), cause the electronic device (201) to provide a 3D image.

[0089] In one embodiment, the processor (250) may perform the overall operation of providing a 3D image. In one embodiment, the processor (250) may include one or more processors for providing a 3D image. Hereinafter, with reference to the drawings, the operation of the processor (250) for providing a 3D image will be described.

[0090] In FIG. 2, the electronic device (201) is illustrated as including a communication circuit (210), a display (220), a sensor (230), a memory (240), and a processor (250), but is not limited thereto. For example, the electronic device (201) may further include at least one of the components included in the electronic device (101) of FIG. 1. For example, the electronic device (201) may not include some components (e.g., the communication circuit (210)) among the communication circuit (210), the display (220), the sensor (230), the memory (240), and the processor (250).

[0091] FIG. 3 is a drawing for explaining binocular disparity according to one embodiment.

[0092] Referring to FIG. 3, in one embodiment, when a left-eye image and a right-eye image are simultaneously output on a screen (e.g., display (220)), binocular parallax may occur due to the distance between the left-eye image and the right-eye image, the position of the left-eye image, and the position of the right-eye image.

[0093] In one embodiment, reference numeral 301 may represent zero parallax. As illustrated in reference numeral 301, in zero parallax, left and right eye images (312, 313) are output at substantially the same points within the screen (311), such that the left eye (332) and right eye (333) of the user (331) may perceive (see) 3D images corresponding to the left and right eye images (312, 313) as being displayed within the screen (311) (e.g., at a depth equal to the depth of the screen (311)).

[0094] In one embodiment, reference numeral 302 may represent positive parallax. As illustrated in reference numeral 302, in positive parallax, by outputting the left eye image (312) on the screen (311) at a left position relative to the right eye image (313), the 3D image (321) may be perceived as being displayed behind the screen (311) (e.g., behind or below the display (220)).

[0095] In one embodiment, reference numeral 303 may represent negative parallax. As illustrated in reference numeral 303, in negative parallax, by outputting the left-eye image (312) to the right relative to the right-eye image (313) on the screen (311), the 3D image (321) may be perceived as being displayed in front of the screen (311) (e.g., in front of the display (220)) (e.g., as protruding in front of the screen (311).

[0096] Hereinafter, by positive parallax, the space formed behind the screen (311) (e.g., the depth of the screen (311)) based on the plane of the screen (e.g., the display (220)) may also be referred to as "positive parallax space." In addition, by negative parallax, the space formed in front of the screen based on the plane of the screen may also be referred to as "negative parallax space."

[0097] Hereinafter, an operation of an electronic device (201) outputting a 3D image (3D image data) through a display (220) so that the 3D image (e.g., a 3D object) (or a 2D image) is perceived or shown to the user as being located in a 3D space may be referred to as an operation of displaying a 3D image through the display (220).

[0098] FIG. 4 is a flowchart (400) for explaining a method of providing a 3D image according to one embodiment.

[0099] Referring to FIG. 4, in operation 401, in one embodiment, the processor (250) may obtain the user's location based on sensing data obtained through the sensor (230).

[0100] In one embodiment, the operation of the processor (250) to obtain the user's location may include the operation of the processor (250) to obtain the locations of the user's eyes (e.g., the user's left and right eyes). Hereinafter, for convenience of explanation, the terms "user's location" and "user's eye location" may be used interchangeably.

[0101] In one embodiment, the processor (250) can obtain sensing data through the ET sensor. The processor (250) can obtain depth information (e.g., a depth map or image) for the field of view area of ​​the ET sensor based on the obtained sensing data. The processor (250) can determine whether a user (e.g., a user's face) is detected within the field of view area of ​​the ET sensor based on the depth information. Based on detection of the user's face within the depth information, the processor (250) can obtain (e.g., calculate) the positions of the user's eyes (e.g., the left eye and the right eye) (e.g., the positions of the user's eyes relative to the position of the ET sensor) using the depth information (e.g., a portion corresponding to the user's face within the depth information).

[0102] In one embodiment, the operation of obtaining the position of the user's eyes may include obtaining the distance between the electronic device (201) (e.g., ET sensor) and the user's eyes, and the direction from the position of the electronic device (201) (e.g., ET sensor) to the position of the user's eyes.

[0103] In one embodiment, the processor (250) may perform an operation of acquiring a user's location based on sensed images acquired through the sensor (230) while a 2D image and / or a 3D image is displayed through the display (220). For example, the processor (250) may perform an operation of acquiring a user's location based on sensed data acquired through the sensor (230) while a 3D image is displayed through the display (220).

[0104] In one embodiment, the above-described examples illustrate, but are not limited to, obtaining the user's location by an ET sensor included in the electronic device (201). For example, the user's location may be obtained through a camera included in an external electronic device wirelessly connected to the electronic device (201). The processor (250) may obtain the user's location by receiving the user's location obtained from the external electronic device from the external electronic device through the communication circuit (210).

[0105] In operation 403, in one embodiment, the processor (250) may provide a first guide indicating that the user is in a state in which the 3D image can be provided, based on whether the user's location is included in an area (hereinafter referred to as a "first area") in which the 3D image can be provided when the 3D image is displayed through the display (220).

[0106] In one embodiment, the processor (250) may determine whether the user's location (e.g., the location of the user's eyes obtained in operation 401) is included in a first area that can be a 3D image through the display (220).

[0107] In one embodiment, the first area (also referred to as a “viewing zone” or “first space”) may be an area (e.g., a space) in which left-eye images and right-eye images of the entire 3D image displayed through the display (220) can be provided separately (without overlapping) to the user’s left and right eyes. The first area will be described below with reference to FIGS. 5A, 5B, 6A, and 6B.

[0108] FIG. 5 is a drawing for explaining a first area according to one embodiment.

[0109] FIG. 5b is a drawing for explaining a first region according to one embodiment.

[0110] FIG. 6A is a drawing for explaining a first area according to one embodiment.

[0111] FIG. 5b is a drawing for explaining a first region according to one embodiment.

[0112] Referring to FIGS. 5A, 5B, 6A, and 6B, in one embodiment, at reference numerals 501 and 502 of FIG. 5, the X-axis may represent a direction corresponding to the width of the display (220) (the display (220) including a lenticular lens or a parallax barrier), the Y-axis may represent a direction corresponding to the height of the display (220), and the Z-axis may represent a direction perpendicular to the display (220) (e.g., a direction corresponding to a distance from the display (220).

[0113] In one embodiment, reference numeral 501 may be a drawing for explaining a first region (A) that can be formed when one 3D pixel data (e.g., data of one left-eye pixel and data of one right-eye pixel) is output through the display (220).

[0114] In one embodiment, at reference numeral 501, a first region (A) may be formed based on a viewing angle (θ1) of the display (220) (e.g., a viewing angle formed from a single aperture formed between unit lenses or barriers of a lenticular lens) and a maximum distance at which a 3D image can be provided. The viewing angle (θ1) of the display (220) may be determined based on characteristics of the display (220).

[0115] In one embodiment, in reference numeral 501, lines (511-1, 511-2) may represent a range in which left-eye pixel data or right-eye pixel data can be provided to a user through a unit lens (a unit lens of a lenticular lens) positioned at a point (511) of the display (220). A viewing angle (θ1) of the display (220) may be an angle between lines (511-1, 511-2).

[0116] In one embodiment, at reference numeral 501 (and reference numeral 502), the distance (d1) may represent a maximum distance from the display (220) at which the left-eye image and the right-eye image of the 3D image can be provided separately (e.g., without the left-eye image and the right-eye image overlapping). For example, when a user (e.g., an eye of the user) is positioned at a distance less than the distance (d1) from the display (220), one pixel data (e.g., the left-eye pixel data or the right-eye pixel data) output from a location on the display (220) can be provided to either the left or the right eye of the user. When the user is positioned at a distance greater than the distance (d1) from the display (220), one pixel data (e.g., the left-eye pixel data or the right-eye pixel data) output from a location on the display (220) can be provided to both the left and right eyes of the user (and can be provided overlappingly to the left and right eyes of the user).

[0117] In one embodiment, at reference numeral 501, line (515) may represent positions that are spaced apart by a distance (d1) from line (514), which represents positions extending from the position of the display (220).

[0118] In one embodiment, at reference numeral 501, the first area (A) may be determined by point (511) and points (512, 513) where line (515) intersects lines (511-1, 511-2).

[0119] In one embodiment, reference numeral 502 may be a drawing for explaining a first area (B) formed in which a 3D image is output throughout the entire area of ​​the display (220).

[0120] In one embodiment, at reference numeral 502, a first region (B) may be formed based on a viewing angle (θ2) of a unit lens (e.g., a unit lens of a lenticular lens) disposed at the far left of the display (220), a viewing angle (θ2) of a unit lens disposed at the far right of the display (220), and a maximum distance at which a 3D image can be provided. The viewing angle (θ2) may be substantially equal to the viewing angle (θ1).

[0121] In one embodiment, in reference numeral 502, lines (521-1, 521-2) may represent a range in which left-eye pixel data or right-eye pixel data can be provided through a unit lens (a unit lens of a lenticular lens) positioned at the leftmost point (521) of the display (220). Lines (522-1, 522-2) may represent a range in which left-eye pixel data or right-eye pixel data can be provided through a unit lens positioned at the rightmost point (522) of the display (220).

[0122] In one embodiment, at reference numeral 502, the first region (B) may be formed by points (531, 532, 533, 534) where lines (521-1, 521-2) and lines (522-1, 522-2) intersect.

[0123] In one embodiment, the distance (d2) may be the minimum distance at which a 3D image can be provided. For example, the distance (d2) may be the distance from the display (220) to the point (532) closest to the display (220) within the first region (B) (e.g., the distance between the line (514) and the line (516) passing through the point (532) and parallel to the width of the display (220).

[0124] In one embodiment, FIG. 5B may be a drawing for explaining a first area (C) formed in which a 3D image is output throughout the entire area of ​​the display (220).

[0125] In one embodiment, in FIG. 5B, a first region (C) may be formed based on a viewing angle (θ3) of a unit lens (e.g., a unit lens of a lenticular lens) disposed at the leftmost side of the display (220), a viewing angle (θ3) of a unit lens disposed at the rightmost side of the display (220), and a maximum distance (d3) at which a 3D image can be provided. In one embodiment, the viewing angle (θ3) may be determined based on the characteristics of the display (220). In one embodiment, the angle between each of the directions in which the viewing angles of the unit lenses (e.g., the unit lenses of the lenticular lens) of the display (220) face (e.g., the directions in which the center line of the viewing angle (θ3) faces) and the direction in which the display (220) faces may vary depending on the characteristics of the display (220).

[0126] In one embodiment, in FIG. 5B, lines (541-1, 541-2) may represent a range in which left-eye pixel data or right-eye pixel data can be provided through a unit lens (a unit lens of a lenticular lens) positioned at the leftmost point (541) of the display (220). Lines (542-1, 542-2) may represent a range in which left-eye pixel data or right-eye pixel data can be provided through a unit lens positioned at the rightmost point (542) of the display (220).

[0127] In one embodiment, in FIG. 5b, the first region (C) may be formed by points (581, 582, 583) where lines (541-2), (542-1), and (553) (e.g., a line representing the maximum distance at which a 3D image can be provided) intersect.

[0128] In one embodiment, the distance (d4) may be the minimum distance at which a 3D image can be provided. For example, the distance (d4) may be the distance from the display (220) to the point (581) closest to the display (220) within the first region (C) (e.g., the distance between lines (551) and (552).

[0129] In one embodiment, in FIG. 5B, reference numeral 571 may represent a user located within the first area (C).

[0130] As described above, the first region (viewing zone) (e.g., region (A), region (B), region (C)) may be a region in which the left-eye image and the right-eye image of the entire 3D image displayed through the display (220) can be provided separately (without overlapping) to the left and right eyes of the user. For example, the first region may be a region in which each of the entire pixels of the display (220) displaying the 3D image can provide left-eye pixel data or right-eye pixel data to the user without crosstalk. For example, when a user (e.g., the user's eyes) is positioned within the first region, the first region may be a region (e.g., a space) in which a 3D image can be provided without crosstalk by an operation for processing a 3D image (e.g., an operation for processing a 3D image in software) performed in the electronic device (201) based on the user's position.

[0131] In one embodiment, the area outside the first area may be an area where a proper 3D image cannot be provided. For example, the area outside the first area may be an area where a 3D image cannot be provided without crosstalk even if the electronic device (201) performs a 3D image processing operation based on the user's location.

[0132] In one embodiment, the first region may be formed differently depending on the positions of pixels of the display (220) that outputs the 3D image. For example, the processor (250) may display a 3D image through one area within the display (220) and display a 2D image through the remaining area within the display (220) excluding the one area. In this case, the position (e.g., space) at which the first region is formed may vary depending on the area within the display (220) that displays the 3D image (e.g., positions of pixels in the area that displays the 3D image).

[0133] In one embodiment, the processor (250) may set a second region (hereinafter referred to as a “second region” or “safe region”) and a third region (hereinafter referred to as a “third region” or “danger region”) within the first region.

[0134] In one embodiment, the third region may be a region that includes a boundary (e.g., a boundary surface) of the first region (e.g., shares a boundary surface of the first region).

[0135] For example, in reference numeral 601 of FIG. 6A, the processor (250) can set a second area (A1) and a third area (A2) within the first area (A). The third area (A2) may be an area that includes a boundary of the first area (A) (e.g., a line connecting the point (511) and the point (512), a line connecting the point (511) and the point (513), and a line connecting the point (512) and the point (513)). For example, in reference numeral 602 of FIG. 6A, the processor (250) can set a second area (B1) and a third area (B2) within the first area (B). The third area (B2) may be an area including a boundary of the first area (B) (e.g., a line connecting point (531) and point (532), a line connecting point (532) and point (533), a line connecting point (533) and point (534), and a line connecting point (534) and point (531)).

[0136] For example, in FIG. 6B, the processor (250) can set a second area (C1) and a third area (C2) within the first area (C). The third area (C2) may be an area that includes a boundary of the first area (C) (e.g., a line connecting point (581) and point (582), a line connecting point (582) and point (583), and a line connecting point (583) and point (581).

[0137] In one embodiment, the third region may be an area closer to the outside of the first region than the second region. When the user is located in the third region, the user may be more likely to leave the first region due to movement than when the user is located in the second region.

[0138] In one embodiment, the second region may be an area within the first region excluding the third region. For example, as illustrated in reference numeral 601, the second region (A1) may be set as an area within the first region (A) excluding the third region (A2). For example, as illustrated in reference numeral 602, the second region (B1) may be set as an area within the first region (B) excluding the third region (B2). As illustrated in reference numeral 6b, the second region (C1) may be set as an area within the first region (C) excluding the third region (C2).

[0139] Referring back to FIG. 4, in one embodiment, the processor (250) may provide a first guide indicating that the user is in a state where a 3D image can be provided based on whether the user's location (e.g., the location of the user's eyes) is included in the first area.

[0140] In one embodiment, the processor (250) may display a 3D image to be crosstalk-provided to the user through the display (220) based on the user's location.

[0141] In operation 405, in one embodiment, the processor (250) may provide a second guide indicating that the user is in a state where the 3D image cannot be provided, based on the user's location (e.g., the location of the user's eyes) not being included in the first area.

[0142] Hereinafter, with reference to FIGS. 7 to 11, an operation of providing a first guide or a second guide and an operation of displaying a 3D image to be provided as crosstalk to a user through a display (220) based on the user's location will be described.

[0143] FIG. 7 is a drawing for explaining a method of providing a first guide or a second guide according to one embodiment.

[0144] FIG. 8 is a drawing for explaining a method of providing a first guide or a second guide according to one embodiment.

[0145] Referring to FIGS. 7 and 8, in one embodiment, the processor (250) may provide a guide including different colors, shapes, and / or texts depending on the user's location.

[0146] In one embodiment, the first guide may include a third guide (hereinafter referred to as the “third guide”) and a fourth guide (hereinafter referred to as the “fourth guide”).

[0147] In one embodiment, the third guide may be a guide that indicates a state in which the user is located in the second area (safe area) and can receive a 3D image through the display (220) when the user's location is included in the second area (safe area).

[0148] In one embodiment, the fourth guide may be a guide indicating that the user is located in the third area (danger area) and can receive a 3D image through the display (220) when the user's location is included in the third area (danger area).

[0149] In one embodiment, at reference numeral 701 of FIG. 7, the processor (250) can determine that the location of the user (711) (e.g., the location of the user (711) acquired through a sensor for eye tracking) is included in the second area (safe area) while a screen (710) including a 3D image (712) is displayed through the display (220). In one embodiment, at reference numeral 702, the processor (250) can generate a third guide (720) including an icon (721) representing the user (711), an object (723) displayed around the icon (721), and an indicator (722) indicating that the user (711) is located in the second area and can be provided with the 3D image (712), based on determining that the location of the user (711) is included in the second area. The processor (250) can display the third guide (720) through the display (220).

[0150] In one embodiment, the processor (250) may provide an indicator (722) (and object (723)) having a first color (e.g., green) to indicate to the third guide (720) that the user (711) is located in the second area and is in a state where a 3D image (712) can be provided.

[0151] In one embodiment, the processor (250), at reference numeral 703 of FIG. 7, can determine that the location of the user (711) is included in the third area (danger area) while a screen (730) including a 3D image (732) is displayed through the display (220).

[0152] In one embodiment, at reference numeral 704, the processor (250) may generate a fourth guide (740) including an icon (741) representing the user (711), an object (744) displayed around the icon (741), an indicator (722) indicating that the user (711) is located in the third area and is in a state where a 3D image (732) can be provided, and text (743) guiding the user (711) to move to the second area (safe area) based on determining that the location of the user (711) is included in the third area. The processor (250) may display the fourth guide (740) through the display (220).

[0175] In one embodiment, at reference numeral 903, a target user (e.g., user (911)) may be located in a third area (danger area). At reference numeral 904, the processor (250) may control the external electronic device (910) to output an indicator (921) indicating that the target user (e.g., user (911)) is located in the third area and is in a state where a 3D image can be provided, as a fourth guide, through light-emitting units (e.g., LED light-emitting units) arranged around ET sensors (910-1, 910-2) included in the external electronic device (910), based on confirmation that the location of the target user (e.g., user (911)) is included in the third area.

[0176] In one embodiment, at reference numeral 904, the processor (250) may control the external electronic device (910) to output an indicator (941) having a second color (e.g., orange) so that the indicator (941) indicates that a target user (e.g., user (911)) is located in a third area and is in a state where a 3D image can be provided.

[0177] In one embodiment, at reference numeral 905, a target user (e.g., user (911)) may be located outside a first area (e.g., outside a first area within a field of view of ET sensors (910-1, 910-2) of the external electronic device (910). At reference numeral 905, the processor (250) may control the external electronic device (910) to output an indicator (961) indicating that the target user (e.g., user (911)) is located outside the first area and cannot receive a 3D image, as a second guide, through a light-emitting unit (e.g., LED light-emitting unit) disposed around the ET sensors (910-1, 910-2) included in the external electronic device (910), based on determining that the target user (e.g., user (911)) is located outside the first area.

[0179] In one embodiment, at reference numeral 1001 of FIG. 10, the processor (250) may control the external electronic device (910) to display a third guide including a first object (1010) representing a first area (e.g., area (A) of FIG. 5A) and a second object (1021) positioned within the first object (1010) and representing a location of the target user (e.g., user (911)) within the first area through a display of the external electronic device (910) (e.g., a display positioned between ET sensors (910-1, 910-2) within the external electronic device (910)) based on the location of the target user (e.g., user (911)) being included in the second area (safe area).

[0180] In one embodiment, in reference numeral 1001, a first object (1010) representing a first region may include objects (1011, 1012, 1013, 1014) representing the first region and corresponding to distances from the display (220) (or a 3D image displayed within the display (220). For example, among the distances represented by the objects (1011, 1012, 1013, 1014), the object (1011) may represent a closest distance from the display (220), and the object (1014) may represent a farthest distance from the display (220). The lengths of the objects (1011, 1012, 1013, 1014) may each represent a width of the first region on an X-axis (e.g., the X-axis in FIG. 5A).

[0181] In one embodiment, as illustrated at reference numeral 1001, the third guide may further include an object (1022) indicating the location of a user (e.g., user (912)) that has not been determined as a target user, in addition to a second object (1021) indicating the location of a target user (e.g., user (911)).

[0182] In one embodiment, the processor (250) may generate the first object (1010) such that the shape of the first object (1010) representing the first area corresponds to the shape of the first area (e.g., the shape of the first object (1010) representing the first area is identical to the shape of the first area).

[0183] In one embodiment, similar to the operation of generating (and displaying) the first object (811) and the second object (851) through FIG. 8, the processor (250) may display the first object (1010) and objects representing users (e.g., the second object (1021) and an object representing a user not determined as a target user (1022)) through the display (220) based on the location of the first area (e.g., the actual location of the first area relative to the location of the display (220)) and the location of the user (e.g., the actual location of the user relative to the location of the display (220).

[0184] In one embodiment, at reference numeral 1002 of FIG. 10, the processor (250) may control the external electronic device (910) to display a fourth guide through the display (220) of the external electronic device (910), the fourth guide including a first object (1010) representing a first area and a second object (1021) positioned within the first object (1010) and representing a location of the target user (e.g., user (911)) within the first area (and an object (1022) representing a location of a user (e.g., user (912)) who is not determined as a target user), based on the location of the target user (e.g., user (911)) being included in a third area (danger area).

[0185] In one embodiment, at reference numeral 1003 of FIG. 10, the processor (250) may control the external electronic device (910) to display a second guide through the display (220) of the external electronic device (910), the second guide including a first object (1010) representing the first area and a second object (1021) representing the location of the target user (e.g., the user (911)) located outside the first area and positioned outside the first object (1010) (and an object (1022) representing the location of a user (e.g., the user (912)) who is not determined as the target user), based on the target user (e.g., the user (911)) being located outside the first area.

[0186] In one embodiment, at reference numerals 1001, 1002, and 1003, the processor (250) may cause an object representing a target user (e.g., user (911)) to be displayed in a different color and / or shape depending on the area to which the target user (e.g., user (911)) belongs. For example, at reference numeral 1001, when the target user is located in a second area, the second object (1021) may have a first color (e.g., green). At reference numeral 1002, when the target user is located in a third area, the second object (1021) may have a second color (e.g., green). At reference numeral 1003, when the target user is located outside the first area, the border of the second object (1021) may be a dotted line.

[0187] FIG. 11 is a drawing for explaining a method of displaying a screen based on a user's location according to one embodiment.

[0188] Referring to FIG. 11, in one embodiment, the processor (250) may display a 3D image through the display (220) so that the 3D image is provided to the user without crosstalk based on whether the location of the user (e.g., a user determined as a target user) is included in the first area. For example, the processor (250) may determine the locations of pixels of the display (220) at which the left-eye image and the right-eye image of the 3D image are to be displayed so that the left-eye image and the right-eye image of the 3D image are provided separately based on the location of the user (e.g., the user's viewpoint) based on whether the user is located within the first area. The processor (250) may display the left-eye image and the right-eye image of the 3D image at the locations of the determined pixels.

[0189] In one embodiment, as shown in reference numeral 1101 of FIG. 11, a user may be positioned in a second area (safe area) within a first area. The processor (250) may display a screen including a 3D image through the display (220) so that the user may view the 3D image without crosstalk at the user's position within the second area.

[0190] In one embodiment, at reference numeral 1102 of FIG. 11, a user (1141) may be located in a third area (a risk area) within a first area. The processor (250) may display a screen including a 3D image through the display (220) so that the user (1141) may view the 3D image without crosstalk at the user's (1141's) location within the third area.

[0191] In one embodiment, at reference numeral 1102, the processor (250) may display information (1122) through the display (220) that guides the user (1141) to move to a safe area (second area) based on the user (1141) being located in the third area.

[0192] In one embodiment, at reference numeral 1103 of FIG. 11, the user (1141) may be located outside the first area. The processor (250) may display a screen including a 2D image through the display (220) based on the user (1141) being located outside the first area.

[0193] In one embodiment, at reference numeral 1103, the processor (250) may display, through the display (220), information indicating that the user (1141) has left the first area and information (1131) indicating that the mode of the electronic device (201) will be switched from a mode of displaying a 3D image to a mode of displaying a 2D image, based on the user (1141) being located outside the first area.

[0194] In the examples described above, the 2D image is displayed based on the user (1141) being located outside the first area, but this is not limited thereto. For example, the processor (250) may display an image through the display (220) so that the 3D image is provided without crosstalk at a designated location (e.g., an optimal location set based on the characteristics of the display (220)).

[0195] Although not illustrated in FIG. 4, at least some of the operations included in FIG. 4 (e.g., obtaining the user's location based on sensing data acquired through the ET sensor) may be performed periodically or based on the occurrence of a specified event.

[0196] FIG. 12 is a flowchart (1200) illustrating a method for determining a target user according to one embodiment.

[0197] Referring to FIG. 12, in operation 1201, in one embodiment, the processor (250) may obtain the locations of one or more users via a sensor (230) (e.g., an ET sensor).

[0198] In one embodiment, the processor (250) may obtain depth information (e.g., a depth map or image) for a field of view of the sensor (230) based on sensing data obtained through the sensor (230). The processor (250) may detect faces of one or more users located within the field of view of the sensor (230) within the depth information. The processor (250) may obtain (e.g., calculate) the positions of eyes of one or more users based on the faces of one or more users detected within the depth information.

[0199] In one embodiment, the act of obtaining the position of each of the eyes of one or more users may include obtaining a distance between the electronic device (201) (e.g., ET sensor) and each of the eyes of the one or more users, and a direction from a position of the electronic device (201) (e.g., ET sensor) to a position of each of the eyes of the one or more users.

[0200] In operation 1203, in one embodiment, the processor (250) can identify at least one user located in the first area based on the locations of one or more users acquired in operation 1201.

[0201] In operation 1205, in one embodiment, the processor (250) may determine a target user from among at least one user (hereinafter also referred to as “at least one user”) located in the first area.

[0202] In one embodiment, the processor (250) may set priorities based on criteria (or conditions) specified for at least one user. The processor (250) may determine, among the at least one user, the user with the highest priority as the target user.

[0203] In one embodiment, the processor (250) may determine, as a target user, at least one user, a user located closest to a designated location, a user who made a gesture corresponding to a designated gesture, a user determined based on an input received from a controller (e.g., a remote control) capable of controlling the electronic device (201), or a user who uttered a designated voice.

[0204] In one embodiment, the processor (250) may determine, based on the 3D advertising content being displayed through the display (220), a user among at least one user having personal information corresponding to the 3D advertising content as the target user.

[0205] In one embodiment, the processor (250) may determine, based on the 3D game being displayed through the display (220), a user who wins the 3D game among at least one user as the target user.

[0206] However, the operation of determining a target user from among at least one user is not limited to the examples described above. Referring to the drawings below, the operation of determining a target user from among at least one user and the operation of displaying a 3D image based on the target user's location (and / or the target user's gesture) will be described in detail.

[0207] In one embodiment, the processor (250) may determine a target user from among at least one user located in the first area or display a 2D image through the display (220) based on whether the target user has moved outside the first area after the target user has been determined. However, the present invention is not limited thereto. For example, the processor (250) may determine whether the target user has moved to an area outside the first area within the field of view of the sensor (230) after the target user has been determined. The processor (250) may maintain the target user (or may not change the target user) based on whether the target user has moved back to the first area within a specified time from the time when the target user has left the first area.

[0208] FIG. 13 is a diagram illustrating a method for determining a target user according to one embodiment.

[0209] FIG. 14 is a diagram illustrating a method for determining a target user according to one embodiment.

[0210] Referring to FIGS. 13 and 14, in one embodiment, reference numeral 1301 of FIG. 13 may represent a situation in which multiple users (1311, 1312, 1313) (hereinafter also referred to as “viewers”) within a home view a screen (e.g., a 3D screen) displayed through a display (220).

[0211] In one embodiment, at reference numeral 1302 of FIG. 13, the processor (250) may perform an operation of recognizing a plurality of users (1311, 1312, 1313) located within a field of view area (1320) of a sensor (230) (e.g., an ET sensor).

[0212] In one embodiment, at reference numeral 1401 of FIG. 14, in one embodiment, the processor (250) may perform an operation of recognizing faces of multiple users (1311, 1312, 1313) through a sensor (230) (e.g., an ET sensor). While performing the operation of recognizing faces of multiple users (1311, 1312, 1313), the processor (250) may display information (1415) indicating that the operation of recognizing faces is being performed through the display (220). The processor (250) can display, through the display (220), a plurality of objects (1411-1, 1412-1, 1413-1) (e.g., icons) corresponding to each of the plurality of users (1311, 1312, 1313), and objects (1411-2, 1412-2, 1413-2) representing (e.g., focusing on) faces in the plurality of objects (1411-1, 1412-1, 1413-1), based on the recognition of faces of the plurality of users (1311, 1312, 1313).

[0213] In one embodiment, although not shown in FIG. 14, the processor (250) can determine that multiple users (1311, 1312, 1313) are located within the first area (viewing zone).

[0214] In one embodiment, the processor (250) may determine, among a plurality of users recognized by the sensor, a user located closest to a designated location as a target user. For example, the processor (250) may determine, among the plurality of users (1311, 1312, 1313), a user (1313) located closest to the location of the electronic device (201) as a target user. However, the present invention is not limited thereto. For example, among the plurality of users (1311, 1312, 1313), the processor (250) may determine, as a target user, a user located closest to an optimal location set based on the characteristics of the display (220).

[0215] In one embodiment, at reference numeral 1402, the processor (250) determines a user (1313) located closest to the location of the electronic device (201) among a plurality of users (1311, 1312, 1313) as a target user, and, based on this, displays the color of the object (1413-2) (and / or the object (1413-1)) through the display (220) so that the object (1413-2) (and / or the object (1413-1)) corresponding to the user (1313) determined as the target user is distinguished from the objects (1411-2, 1412-2) (and / or the objects (1411-1, 1412-1)) corresponding to other users (1311, 1312). 1412-1)) can be displayed in a different color. The processor (250) can display information (1416) asking whether to determine (e.g., designate) the user (1313) as the final target user through the display (220) based on determining the user (1313) located closest to the location of the electronic device (201) among the plurality of users (1311, 1312, 1313) as the target user.

[0216] In one embodiment, at reference numeral 1403, the processor (250) may display, through the display (220), information (1417) indicating that the user (1313) is determined as the final target user, based on determining the user (1313) as the final target user, along with information (1418) indicating that an operation of tracking the position of the user (1313) as the final target user (e.g., the position of the eyes of the user (1313)) will be performed based on determining the user (1313) as the final target user. The processor (250) may perform an operation such that a 3D image is provided to the user (1313) without crosstalk by tracking the position of the user (1313) as the final target user based on determining the user (1313) as the final target user.

[0217] In one embodiment, the processor (250) may determine a user as a target user based on an input received from a controller (e.g., a remote control) capable of controlling the electronic device (201). For example, in FIG. 14, the processor (250) may determine one of a plurality of users (1311, 1312, 1313) as a target user based on a user input using a remote control capable of controlling the electronic device (201).

[0218] In one embodiment, the processor (250) may determine a user based on a user's gesture as a target user. For example, in FIG. 14, the processor (250) may recognize a user's gesture using a gesture sensor. The processor (250) may determine one of a plurality of users (1311, 1312, 1313) as a target user based on the recognized gesture. However, the present invention is not limited thereto. The processor (250) may determine a user who has uttered a specified voice as a target user. For example, the processor (250) may acquire a voice through a microphone. The processor (250) may determine the user who has uttered the voice as a target user based on whether the acquired voice corresponds to a specified voice (e.g., a voice associated with target user settings).

[0219] FIG. 15 is a diagram illustrating a method for determining a target user according to one embodiment.

[0220] FIG. 16 is a diagram illustrating a method for determining a target user according to one embodiment.

[0221] Referring to FIGS. 15 and 16, in one embodiment, reference numeral 1501 of FIG. 15 may represent a situation in which a plurality of users (1511, 1512) in an external public place view a screen (e.g., a 3D screen) displayed through a display (220) of an electronic device (201) (e.g., a kiosk device, an electronic device (201) for displaying guidance information and / or advertisements).

[0222] In one embodiment, at reference numeral 1302 of FIG. 15, the processor (250) may perform an operation of recognizing a plurality of users (1511, 1512) located within a field of view area (1521) of a sensor (230) (e.g., an ET sensor).

[0223] In one embodiment, at reference numeral 1601 of FIG. 16, in one embodiment, the processor (250) may perform an operation of recognizing faces of multiple users (1511, 1512) through a sensor (230) (e.g., an ET sensor). After performing the operation of recognizing faces of multiple users (1511, 1512), the processor (250) may display information (1515) indicating that faces are recognized through the display (220). The processor (250) can display, through the display (220), a plurality of objects (1511-1, 1512-1) corresponding to each of the plurality of users (1511, 1512), and objects (1511-2, 1512-2) representing faces (e.g., focusing on faces) in the plurality of objects (1511-1, 1512-1), based on the recognition of the faces of the plurality of users (1511, 1512).

[0224] In one embodiment, although not shown in FIG. 16, the processor (250) can determine that multiple users (1511, 1512) are located within the first area (viewing zone).

[0225] In one embodiment, at reference numeral 1602, the processor (250) determines a user (1511) located closest to the location of the electronic device (201) among a plurality of users (1511, 1512) as a target user, and, based on this, the object (1511-2) (and / or object (1511-1)) corresponding to the user (1511) determined as the target user can be distinguished from the objects (1512-2) (and / or object (1512-1)) corresponding to other users (1512) by displaying the color of the object (1511-2) (and / or object (1511-1)) differently from the color of the objects (1512-2) (and / or object (1512-1)) through the display (220).

[0226] In one embodiment, at reference numeral 1602, the processor (250) may display, through the display (220), information (1525) indicating that an operation of tracking the location of the user (1511) as the target user (e.g., the location of the eyes of the user (1511)) will be performed, along with information (1526) indicating that the user (1511) is determined to be the target user, based on determining the user (1511) as the target user.

[0227] FIG. 17 is a drawing for explaining a method for providing a 3D image according to one embodiment.

[0228] Referring to FIG. 17, as described above, in one embodiment, the processor (250) may display a 3D image to be crosstalk-provided to the user through the display (220) based on the location of the user (e.g., target user).

[0229] In one embodiment, the processor (250) may control the display (220) to orient the 3D image toward the location of a user (e.g., a target user).

[0230] In one embodiment, the processor (250) may display a 3D image corresponding to the direction of the face of a user (e.g., a target user) (or the direction of the user's gaze) through the display (220).

[0231] In one embodiment, at reference numeral 1701 of FIG. 17, the processor (250) may display a 3D screen (1710) including a 3D image and a first guide (1715) to be crosstalk-provided to the user through the display (220) based on the location of the user (1711) (e.g., target user). The processor (250) may obtain (e.g., calculate) a direction toward which the face of the user (1711) is facing based on an image of the face of the user (1711) obtained through a sensor (230) (e.g., an ET sensor).

[0232] In one embodiment, at reference numeral 1702, the processor (250) may display the screen (1720) so that the screen (1710) appears to be rotated based on a direction corresponding to a direction in which the face of the user (1711) is facing. For example, the processor (250) may display the screen (1720) through the display (220) so that the screen (1720) appears to be facing the front of the face of the user (1711). For example, the processor (250) may display the screen (1720) through the display (220) so that the direction in which the screen (1720) is facing and the direction in which the face of the user (1711) is facing are perpendicular to each other. For example, as illustrated in reference numeral 1702, the processor (250) may control the display (220) such that the left side of the screen (1720) is displayed in negative parallax space and the right side of the screen (1720) is displayed in positive parallax space.

[0233] In one embodiment, when the display (220) displays a 3D image corresponding to the direction of the face (or the direction of the user's gaze) of the user (1711) (e.g., the target user), the user (1711) can perform more precise interactions with the screen (1720). For example, when the screen (1720) is displayed through the display (220) so that the screen (1720) appears to face the front of the user's (1711) face, the user (1711) can input more precise inputs with respect to executable objects (e.g., icons) included in the screen (1720) using the user's finger (or hand gesture (1712)).

[0234] In one embodiment, the processor (250) may perform operations to rotate, zoom in, zoom out, and / or close up a 3D image (or a screen including a 3D image) based on a hand gesture (1712).

[0235] FIG. 18 is a diagram illustrating a method for determining a target user according to one embodiment.

[0236] Referring to FIG. 18, in one embodiment, the processor (250) may determine a target user among a plurality of users based on content displayed through the display (220). For example, the processor (250) may determine a user who wins a 3D game among a plurality of users as a target user based on a screen of a 3D game displayed through the display (220).

[0237] In one embodiment, in FIG. 18, the processor (250) can identify multiple users (1821, 1822) (e.g., identities of the multiple users (1821, 1822)) based on information acquired through the sensor (230) (e.g., ET sensor). For example, the processor (250) can perform face recognition (e.g., facial recognition) on the multiple users (1821, 1822) based on information acquired through the sensor (230) (e.g., ET sensor). The processor (250) can identify (or authenticate) the multiple users (1821, 1822) by comparing features of faces acquired through face recognition with features of faces stored in the memory (240).

[0238] In one embodiment, when a 3D game application is executed, the processor (250) may acquire information on a plurality of users (1821, 1822) playing a 3D game based on user input. While the 3D game application is executed, the processor (250) may display a screen (1810) including a 3D object (1811) through the display (220). The processor (250) may, among the acquired information on the plurality of users (1821, 1822), identify information on a user who won the 3D game among the plurality of users (1821, 1822). The processor (250) may determine a user corresponding to the identified information among the identified plurality of users (1821, 1822) as a target user.

The processor (250) may determine (e.g., predict) the gender and / or age group as personal information of a plurality of users (1921, 1922) by analyzing (e.g., using an artificial intelligence model) information (e.g., images) acquired via the sensor (230). For example, the processor (250) may recognize the faces of the plurality of users (1921, 1922) based on the information acquired via the sensor (230). The processor (250) can determine (e.g., predict) the gender and / or age group as personal information of the plurality of users (1921, 1922) based on the features of the recognized faces (or the items worn by the plurality of users (1921, 1922) and / or the hairstyles of the plurality of users (1921, 1922). The processor (250) can determine, among the plurality of users (1921, 1922), a user (1921) who has personal information corresponding to 3D advertising content as a target user. For example, the processor (250) can determine, among the plurality of users (1921, 1922), a user (1921) who is predicted to have a gender (e.g., female) and an age group (e.g., 30s to 40s) suitable for a perfume advertisement as 3D advertising content as a target user.

[0242] In one embodiment, the processor (250) can display 3D advertising content through the display (220) so that the user (1921) is provided with 3D advertising content without crosstalk after the user (1921) is determined as a target user.
