Certain embodiments of the disclosure relate to a method for changing settings of a virtual and augmented reality display and an electronic device.
With the development of digital technology, various types of electronic devices such as mobile communication terminals, personal digital assistants (PDAs), electronic organizers, smartphones, tablet personal computers (PCs), and wearable devices have become widely used. Development continues to support and increase the function of these electronic devices, resulting in improvements to hardware and/or the software.
For example, an electronic device may facilitate virtual reality (VR) services, allowing a user to have a realistic experience in a virtual world generated by a computer. In addition, the electronic device may provide augmented reality (AR) services, in which virtual information (or object) is added to a real-world view. Furthermore, some devices provide a mixed reality (MR) service in which a VR and AR are mixed into a single experience. The electronic device may include a heads-up display (HUD) to provide such VR and AR services.
An electronic device such as a HUD may be worn on the user's head, and include a first panel corresponding to the left eye, and a second panel corresponding to the right eye. A display module may be included in the device frame (e.g., housing). The display module may include the first panel and second panel. The electronic device may display a screen through the first panel and the second panel with some matching elements (e.g., to provide a stereoscopic effect). When the electronic device outputs a screen through the first panel and the second panel, a large amount of power is consumed, the potential usage time of the electronic device may be reduced, and the temperature of the electronic device may increase due to the resultant generated heat.
Certain embodiments of the disclosure may provide device and a method that distinguishes between the dominant eye and the non-dominant eye of the user, and change settings of the display panel corresponding to the non-dominant eye to reduce power consumption.
An electronic device according to certain embodiments may include: a first camera configured to capture a frontal external environment of the electronic device, a second camera oriented opposite to the first camera and configured to capture gaze directions of a user's left eye and right eye, a first display panel corresponding to the left eye, a second display panel corresponding to the right eye, a memory, and a processor operably connected to the first camera, the second camera, the first display panel, the second display panel, and the memory, wherein the processor is configured to: identify, using the second camera, a dominant eye and a non-dominant eye among the left eye and right eye, identify a dominant display panel from among the first and second display panels corresponding to the dominant eye, and a non-dominant display panel from among the first and second display panels corresponding to the non-dominant eye, and change settings of the dominant display panel to be different from settings of the non-dominant display panel.
A method according to certain embodiments may include: identifying, using one or more of a first camera configured to capture a frontal external environment of the electronic device, or a second camera oriented opposite to the first camera and configured to capture gaze directions of user's left and right eyes, a dominant eye and a non-dominant eye from among the user's left eye and right eye, identifying, using at least one processor, a dominant display panel from among first and second display panels corresponding to the dominant eye, and a non-dominant display panel from among the first and second display panels corresponding to the non-dominant eye, and changing settings of the dominant display panel to be different from settings of the non-dominant display panel.
Certain embodiments of the disclosure may identify the dominant eye and/or the non-dominant eye from among the eyes of the user, and change at least some of settings of a display panel corresponding to the non-dominant eye, which may reduce current consumption of the electronic device.
According to certain embodiments, the electronic device may determine a dominant eye and a non-dominant eye of a user, and change settings of a display panel corresponding to the non-dominant eye to be at least partially different from the settings of the display panel corresponding to the dominant eye. The electronic device may change at least some of the settings of the display panel corresponding to the non-dominant eye so as to lower the quality of this display panel.
According to certain embodiments of the disclosure, with the change in settings to the display panel(s), current consumption of the electronic device may be reduced, the potential usage time of the device may increase, and heat generation may be reduced.
In addition, various effects directly or indirectly identified through this document may be provided.

According to an embodiment, the processor 120 may be configured to measure the distance to an object using the first camera 315, identify the gaze direction of the user's left and right eyes by using the second camera 313 based on detecting that the measured distance exceeds a threshold value, and change at some of the settings of the non-dominant display panel corresponding to the non-dominant eye based on determining that the measured distance exceeds a threshold value.
According to an embodiment, the electronic device 101 may further include an illuminance sensor (e.g., illuminance sensor 322 in
According to an embodiment, the processor 120 may be configured to identify the movement of an object to which a gaze of the user is directed based on a direction of the gaze, identify whether the movement of the object exceeds a preset reference value, and reduce the frame rate of the non-dominant display panel corresponding to the non-dominant eye based on determining the movement exceeds the reference value.
According to an embodiment, the processor 120 may be configured to reduce one or more of a resolution and a frame rate of the non-dominant display panel corresponding to the non-dominant eye, based on a preset time interval.
According to an embodiment, the processor 120 may be configured to detect eye the movement of the left eye and the right eye, determine whether the detected eye movement exceeds a preset reference value, and reduce the display area of the non-dominant display panel corresponding to the non-dominant eye based on determining that the eye movement exceeds the reference value.
According to an embodiment, the processor 120 may be configured to display a virtual object on the first display panel and the second display panel, and identify the gaze direction of the left eye and the gaze direction of the right eye, as the user gazes at an object through the displayed virtual object using the second camera, and wherein the non-dominant eye is identified from among the left eye and the right eye based on the identified left eye and right eye gaze directions.
According to an embodiment, the electronic device 101 may further include a third camera (e.g., gesture camera 311 in
According to an embodiment, the processor 120 may be configured to determine whether the dominant eye is changed based on detection of the gaze direction of the left eye and the gaze direction of the right eye, and based on determining that the dominant eye has been changed from the right eye to the left eye, change at least some of the settings of the display panel corresponding to the right eye, or revert the settings of the display panel corresponding to the left eye to initial settings.
According to an embodiment, the example electronic device (e.g., electronic device 101 in
According to an embodiment, the processor (e.g., processor 120 in
According to an embodiment, the electronic device 101 may include an eye tracking camera (e.g., eye tracking camera 313 in
The first eye tracking camera may track the gaze direction of the left eye, and the second eye tracking camera may track the gaze direction of the right eye. In general, when the user gazes at a specific object, one eye that accurately gazes at the object may be referred to as a dominant eye, and the other eye other than the dominant eye may be referred to as a non-dominant eye. According to an embodiment, the electronic device 101 may identify the gaze directions of the left and right eyes by using the eye tracking camera 313, and may distinguish the dominant eye from the non-dominant eye among both of the user's eyes based on the identified gaze directions.
At operation 401, the processor (e.g., processor 120 in
At operation 403, the processor 120 may identify the dominant eye and/or the non-dominant eye from among the left eye and/or right eye of the user, based on the identified gaze directions. For example, the dominant eye may be mainly used when the user gazes at the object, and the non-dominant eye may refer to an eye that is supplementally used to gaze at the object. The dominant eye and non-dominant eye of the user may be identified through examination or testing, and the user may be notified of their dominant eye and non-dominant eye. According to an embodiment, when the user perceives real space (e.g., the external environment), perception may be based on the field of view of the dominant eye.
At operation 405, the processor 120 may change at least some of the settings of the display panel corresponding to the non-dominant eye. For example, when gazing at a specific object, the gaze primarily uses the dominant eye, and so the display performance of the dominant-eye display panel (e.g., corresponding to the dominant eye) may affect the user's perceptive ability. On the other hand, the display performance of the non-dominant-eye display panel (e.g., corresponding to the non-dominant eye) may have relatively less influence on the user's perceptive ability. According to an embodiment, the processor 120 may change at least some of the settings of the non-dominant display panel corresponding to the user's non-dominant eye, which in turn may reduce the amount of power consumed by the non-dominant display panel corresponding to the user's non-dominant eye. According to an embodiment, the processor 120 may change the settings of the display panel corresponding to the non-dominant eye at a level that is imperceptible to the user. For example, the processor 120 may lower the resolution of the display panel corresponding to the non-dominant eye and/or lower the frame rate displayed through the display panel. As another example, the processor 120 may reduce the size of the display area of the display panel corresponding to the non-dominant eye. According to an embodiment, the processor 120 may change the settings of the display panel corresponding to the non-dominant eye to be at least partially different from the settings of the display panel corresponding to the dominant eye. According to an embodiment, the processor 120 may change the settings of the display panel based on hardware or may change the settings of the display panel based on software (e.g., application program).
At operation 501, the processor 120 may identify the dominant eye and non-dominant eye of the user. Operation 501 may include substantially the same process as operation 403 in
According to an embodiment, the processor 120 may obtain context information by using the sensor module (e.g., sensor module 176 in
At operation 505, the processor 120 may reduce the display resolution of the non-dominant display panel corresponding to the non-dominant eye. For example, the processor 120 may reduce the resolution of the display panel to a degree that the reduction cannot readily be perceived by the user. The processor 120 may lower the resolution of the display panel corresponding to the user's non-dominant eye, thereby reducing power consumption according to the driving of the display panel. For example, the change (or modification) of the display panel corresponding to the non-dominant eye may be set to a level that is imperceptible to the user.
According to an embodiment, the processor 120 may obtain an illuminance sensing value from the sensor module 176, and may lower both the resolution of the display panel corresponding to the dominant eye and the resolution of the display panel corresponding to the non-dominant eye if the illuminance sensing value is less than or equal to a first threshold value. The processor 120 may adjust the resolution of the display panel corresponding to the non-dominant eye to be lower than the resolution of the display panel corresponding to the dominant eye. For example, it may adjust the resolution of the display panel corresponding to the dominant eye based on the illuminance sensing value, and may adjust the resolution of the display panel corresponding to the non-dominant eye to be lower than the resolution of the display panel corresponding to the dominant eye.
According to an embodiment, the electronic device 101 may lower the resolution of the display panel to a level that the user may not recognize, and may reduce power consumption due to the display panel. The usage time of the electronic device 101 may increase, and heat generation due to the driving of the display panel may be reduced.
With reference to Table [a] and Table [b], the electronic device 101 may change the resolution of the display panel corresponding to the dominant eye or the display panel corresponding to the non-dominant eye based on a preset time interval (e.g., 1 second (s)). With reference to Table [a], the processor (e.g., processor 120 in
According to certain embodiments, the degree of change in time interval and resolution may have a plurality of settings. For example, the processor 120 may divide the resolution of the display panel corresponding to the dominant eye and the display panel corresponding to the non-dominant eye into multiple levels, and change it at multiple levels. As another example, the processor 120 may set different time intervals (e.g., period (time interval), time to change from FHD to HD and/or time to change from HD to FHD) for changing the resolution of the display panel corresponding to the non-dominant eye.
According to an embodiment, the electronic device 101 may reduce power consumption due to the display panel by setting the resolution of the display panel corresponding to the non-dominant eye to be low. The electronic device 101 may adjust the resolution to be lower at a level that the user may not recognize.
At operation 701, the processor 120 may identify the user's dominant eye and non-dominant eye. Operation 701 may include substantially the same process as operation 403 in
At operation 703, the processor 120 may detect a movement of an object that the user is gazing at, using at least one camera. For example, the object the user is gazing at may include a virtual object displayed on the display module (e.g., display module 160 in
At operation 705, the processor 120 may adjust the frame rate of the display panel corresponding to the non-dominant eye. For example, when the movement of the object the user is gazing at among at least one object being displayed on the display is below a preset threshold, the processor 120 may reduce the frame rate of the display panel. The reduction in frame rate may be set to a level that is imperceptible to the user. The processor 120 may decrease the frame rate of the display panel corresponding to the user's non-dominant eye, thereby reducing power consumption due to the driving of the display panel. For example, the change in display performance of the display panel corresponding to the non-dominant eye may be set to a level that is imperceptible to the user.
According to an embodiment, when the movement of the object the user is gazing at among the at least one object being displayed on the display is less than or equal to a first threshold value, the processor 120 may lower both the frame rate of the display panel corresponding to the dominant eye and the frame rate of the display panel corresponding to the non-dominant eye. The processor 120 may adjust the frame rate of the display panel corresponding to the non-dominant eye to be lower than the frame rate of the display panel corresponding to the dominant eye. According to another embodiment, when the movement of the object the user is gazing at among the at least one object being displayed on the display is greater than the first threshold value and less than or equal to a second threshold value, the processor 120 may set the frame rate of the display panel corresponding to the non-dominant eye to be lower than the frame rate of the display panel corresponding to the dominant eye.
According to an embodiment, the electronic device 101 may lower the frame rate of at least some of the display panels at a level that is imperceptible to the user, and reduce power consumption due to the display panel. The usage time of the electronic device 101 may increase, and heat generation due to the driving of the display panel may be reduced.
With reference to Table [a] and Table [b], the electronic device 101 may change the frame rate of each display panel based on a preset time interval (e.g., 1 second (s)). With reference to Table [a], the processor (e.g., processor 120 in
According to certain embodiments, the change in time interval and frame rate may have a plurality of settings. For example, the processor 120 may divide the frame rate of the display panel corresponding to the dominant eye and the display panel corresponding to the non-dominant eye into three or more levels such as 60 Hz, 120 Hz and 144 Hz, and change it at those levels. As another example, the processor 120 may set different time intervals (e.g., time to change from 60 Hz to 120 Hz and/or time to change from 120 Hz to 60 Hz) for changing the frame rate of the display panel corresponding to the non-dominant eye. According to an embodiment, the frame rate of the display panel corresponding to the non-dominant eye may be changed by selecting one of plural frame rate settings based on the speed of movement of the object the user is gazing at among at least one object being displayed on the display.
According to an embodiment, the electronic device 101 may reduce power consumption due to the display panel by setting the frame rate of the display panel corresponding to the non-dominant eye to be low. The electronic device 101 may adjust the frame rate to be lower at a level that the user may not recognize.
At operation 901, the processor 120 may identify the user's dominant eye and non-dominant eye. Operation 901 may include substantially the same process as operation 403 in
At operation 903, the processor 120 may detect a movement of the user's pupils (e.g., left eye and right eye) by using at least one camera (e.g., eye tracking camera 313). For example, the processor 120 may identify the level of movement of the user's eyes by comparing the pupil movement with preset pupil movement related information. The processor 120 may determine whether the pupil moves more or less than a set movement level. For example, when the movement of the pupil is below a preset threshold, the movement of the region where the user gazes may also be small, and even if the size of the display area of the display panel corresponding to the non-dominant eye is adjusted to be small, it may be imperceptible to a user. According to an embodiment, the electronic device 101 may reduce the size of the display area of the display panel corresponding to the non-dominant eye within a level that is imperceptible to the user. According to an embodiment, the processor 120 may perform operation 905 if the movement of the user's pupil (e.g., left eye and/or right eye) detected using at least one camera (e.g., eye tracking camera 313) is below a specified level or threshold, and may perform operation 901 according to a period or an event occurrence (e.g., a change in at least one object displayed on the display) if the movement of the user's pupil (e.g., left eye and/or right eye) is higher than or equal to the specified level or threshold.
At operation 905, the processor 120 may reduce the size of the display area of the display panel corresponding to the non-dominant eye. For example, the processor 120 may reduce the display area of the display panel by a degree that is imperceptible to the user. The processor 120 may thus reduce the amount of power consumed due to the driving of the display panel, by reducing the size of the display area of the display panel corresponding to the user's non-dominant eye. For example, the reduction of the size of the display area of the display panel corresponding to the non-dominant eye may be set to a level that is imperceptible by the user. According to an embodiment, when the movement of the user's pupil detected using at least one camera (e.g., eye tracking camera 313) is less than or equal to a first threshold value, the processor 120 may reduce both the display area of the display panel corresponding to the dominant eye and the display area of the display panel corresponding to the non-dominant eye. According to another embodiment, when the movement of the user's pupil is greater than or equal to a second threshold value greater than the first threshold value, the processor 120 may set the display area of the display panel corresponding to the dominant eye to be the same as the display area of the display panel corresponding to the non-dominant eye. According to another embodiment, when the movement of the user's pupil is greater than the first threshold value and less than the second threshold value, the processor 120 may set the display area of the display panel corresponding to the non-dominant eye to be smaller than the display area of the display panel corresponding to the dominant eye.
According to an embodiment, the electronic device 101 may reduce the display area of the display panel at a level that is imperceptible to the user, and reduce power consumption due to the display panel. The usage time of the electronic device 101 may increase, and heat generation due to the driving of the display panel may be reduced.
According to an embodiment, when the user's pupil (or gaze) deviates from the display area of the display panel corresponding to the non-dominant eye being set smaller than the display area of the display panel corresponding to the dominant eye, the electronic device 101 may set the display area of the display panel corresponding to the non-dominant eye to be the same as the display area of the display panel corresponding to the dominant eye. For example, the electronic device 101 may check whether the user's pupil (or gaze) deviates from the display area of the display panel corresponding to the non-dominant eye by using at least one camera (e.g., eye tracking camera 313).
With reference to
With reference to
The display areas of the first display panel and the second display panel are shown as a circle in the examples of
At operation 1103, the processor 120 may determine whether the user's right eye is the dominant eye. For example, the processor 120 may distinguish the user's dominant eye and the non-dominant eye, and may adjust the performance of the display panel corresponding to the non-dominant eye. According to an embodiment, if the right eye is the dominant eye among both eyes of the user, the left eye may be determined as the non-dominant eye. If the left eye is the dominant eye among both eyes of the user, the right eye may be determined to be the non-dominant eye.
If the right eye is determined to be the dominant eye at operation 1103, at operation 1105, the processor 120 may change at least some of the settings of the display panel corresponding to the left eye (e.g., the non-dominant eye). For example, the processor 120 may change at least some of the settings of the display panel corresponding to the non-dominant eye so that the quality of the above display panel is lowered. According to an embodiment, the processor 120 may change at least some of the settings of the display panel corresponding to the non-dominant eye when a specified condition is satisfied. For example, the processor 120 may lower the resolution of the display panel corresponding to the non-dominant eye if the illuminance sensing value is less than or equal to a threshold value, may reduce the frame rate if the movement of the content displayed on the display panel corresponding to the non-dominant eye is small, or may reduce the size of the display area of the display panel corresponding to the non-dominant eye if the movement of the user's pupil is small.
At operation 1107, the processor 120 may check whether the existing dominant eye (and/or non-dominant eye) has been changed. For example, the processor 120 may detect the movement of the user's pupils (e.g., left eye and right eye) by using at least one camera (e.g., eye tracking camera, such as 313 in
If the dominant eye has been changed, at operation 1109, the processor 120 may adjust the performance of the display panel corresponding to the right eye (e.g., which now corresponds to the non-dominant eye).
In certain embodiments, the meaning that the electronic device 101 detects that the user's dominant eye and non-dominant eye have been changed may include detecting that when the user gazes at a specific object, the eye that mainly gazes at the object among both eyes has been changed. For example, while the user is gazing at an object with the dominant eye, when the user looks at the object through the non-dominant eye as the object is out of the field of view of the dominant eye, the electronic device 101 may determine that the user's dominant eye and non-dominant eye have been changed.
According to an embodiment, the electronic device 101 may periodically identify the user's dominant eye or non-dominant eye, and if the dominant eye (or non-dominant eye) has been changed, at least some of the settings of the display panel corresponding to the dominant eye (or non-dominant eye) may be changed. The electronic device 101 may identify the display panel corresponding to the changed non-dominant eye, and may change at least some of the settings of the corresponding display panel. According to an embodiment, the settings can be changed so that the quality of the display panel corresponding to the non-dominant eye is lower than the quality of the display panel corresponding to the dominant eye.
According to certain embodiments, the settings of a display panel may include a resolution setting of the display panel, a frame rate setting of the display panel, and/or a size setting of the display area of the display panel. The electronic device 101 may change at least one of a resolution setting of the display panel, a frame rate setting of the display panel, and/or a size setting of the display area of the display panel.
According to an embodiment, the electronic device 101 may change at least some of the settings of the display panel corresponding to the changed non-dominant eye at a level that the user cannot recognize. The electronic device 101 may reduce the amount of power consumed by the display panel, the usage time may be lengthened correspondingly, and heat generation of the electronic device 101 may be reduced.
According to certain embodiments, the electronic device 101 may check a condition for adjusting the quality for the dominant eye and/or the non-dominant eye periodically or when a specified event occurs (e.g., movement of the electronic device 101 or change of a displayed virtual object). For example, the condition for adjusting the quality for the dominant eye and/or non-dominant eye may include a change in the illuminance sensing value, a change in the movement of content displayed on the display panel, a change in the movement of the user's pupil, or a change between the dominant eye and the non-dominant eye. According to certain embodiments, upon identifying a condition for adjusting the quality for the dominant eye and/or non-dominant eye, the electronic device 101 may make at least one of a resolution change, a frame rate change, or a size change of the display area of the display panel, for the dominant eye and/or the non-dominant eye. For example, based on at least one of a case in which the illuminance sensing value is less than or equal to a threshold value, a case in which a change in the movement of content displayed on the display panel is small, or a case in which a change in the movement of the user's pupil is small, the electronic device 101 may perform at least one of an operation of lowering the resolution of the display panel corresponding to the non-dominant eye, an operation of lowering the frame rate, or an operation of reducing the size of the display area of the display panel.
Situation [a] illustrates a situation in which the user gazes at a specific object 1205 located in front of the user. According to an embodiment, when the user gazes at the specific object 1205, a difference can be discerned between the dominant eye (e.g., right eye 1201) that is primarily used, and the non-dominant eye (e.g., left eye 1203) that is supplemental. The electronic device 101 (e.g., electronic device 101 in
Situation [b] illustrates a situation in which a specific object 1206 moves to one side with respect to the electronic device 101 and then the user gazes at the specific object 1206. Previously, the user's right eye 1201 was set as the dominant eye, and the left eye 1203 may have been set as the non-dominant eye. According to an embodiment, when the specific object 1206 moves to one side and is out of the field of view of the right eye 1201, the dominant eye may be changed from the right eye 1201 to the left eye 1203. The change of the dominant eye from the right eye 1201 to the left eye 1203 may likewise indicate that the non-dominant eye is changed from the left eye 1203 to the right eye 1201. According to an embodiment, the electronic device 101 may confirm that the dominant eye and the non-dominant eye gazing at the specific object 1206 have been changed, using the first eye tracking camera 1211 and the second eye tracking camera 1213. According to an embodiment, in response to the change of the dominant eye, the electronic device 101 may change at least some of the settings of the display panel included in the second glass 230 (e.g., second glass 230 in
According to an embodiment, the electronic device 101 may periodically check the fields of view of both of the user's eyes (e.g., left eye or right eye). The electronic device 101 may detect whether the object the user is gazing at is out of the field of view of the eye corresponding to the dominant eye, and may determine that the dominant eye has been changed if the object is out of the field of view of the dominant eye.
According to an embodiment, upon confirming a change of the dominant eye (or non-dominant eye), the electronic device 101 may change the display performance of the display panel corresponding to the non-dominant eye. For example, when the non-dominant eye has been shifted from the left eye 1203 to the right eye 1201, the electronic device 101 may lower the display performance of the display panel corresponding to the right eye 1201. Correspondingly, when the dominant eye has been shifted from the right eye 1201 to the left eye 1203, the electronic device 101 may restore the display performance of the display panel corresponding to the left eye 1203 to the initial settings. For example, the display performance of the display panel corresponding to the left eye 1203 may be better than the display performance of the display panel corresponding to the right eye 1201.
With reference to
According to an embodiment, the electronic device 101 may measure the distance to the specific object 1305 by using the distance measuring camera 1315. According to an embodiment, if the measured distance is greater than or equal to a threshold value, the electronic device 101 may identify the gaze directions of both of the user's eyes (e.g., right eye 1301 and/or left eye 1303) by using the first eye tracking camera 1311 and/or the second eye tracking camera 1313. The electronic device 101 may distinguish the dominant eye and the non-dominant eye based on the identified gaze directions. For example, in case of confirming that the gaze direction of the right eye 1301 is the direction gazing at the specific object 1305 while passing through the virtual object 1320 formed on the first glass 220 (e.g., first glass 220 in
According to another embodiment, if the distance to the specific object 1305 measured using the distance measuring camera 1315 is greater than or equal to a set threshold value, the electronic device 101 may display a virtual object on the display panel and identify the user's dominant eye and non-dominant eye. For example, when the distance to the specific object 1305 is less than the set threshold value, the electronic device 101 may not change the display performance of the display panel corresponding to the non-dominant eye.
According to an embodiment, while gazing at the specific object 1305 at a specified distance or more using the distance measuring camera 1315, the electronic device 101 may identify the gaze directions of the left eye and the right eye by using the first eye tracking camera 1311 or the second eye tracking camera 1313, and identify at least one of the dominant eye or the non-dominant eye among the left eye and the right eye based on the identified gaze direction related information. For example, when the distance to the specific object 1305 is less than the set threshold value, the electronic device 101 may not change the display performance of the display panel corresponding to the non-dominant eye.
With reference to
According to certain embodiments, the method of detecting the user's dominant eye and/or non-dominant eye is not limited to the embodiment shown in
According to an embodiment, the electronic device 101 may display a virtual object through the first display panel included in the first glass 220 corresponding to the user's right eye 1301 and/or the second display panel included in the second glass 230 corresponding to the user's left eye 1302. The processor 120 of the electronic device 101 may track the user's gaze direction toward the virtual object through the first eye tracking camera 1311 for tracking the gaze direction of the right eye 1301 and/or the second eye tracking camera 1313 for tracking the gaze direction of the left eye 1303, and may detect the user's dominant eye and/or non-dominant eye based on the gaze direction.
In
According to an embodiment, the first region 1411 may be defined as a region in which the user's right eye 1401 and left eye 1402 have substantially equivalent dominance. For example, when the user gazes at an object located in the first region 1411, the electronic device 101 may identify the user's gaze direction by using at least one camera (e.g., eye tracking camera 313 in
According to an embodiment, the second region 1412 may be defined as a region in which the user's left eye 1402 has dominance. For example, when the user looks at an object located in the second region 1412, the user's left eye 1402 may be determined as the dominant eye, and the user's right eye 1401 may be determined as the non-dominant eye.
According to an embodiment, the third region 1413 may be defined as a region in which the user's right eye 1401 has dominance. For example, when the user looks at an object located in the third region 1413, the user's right eye 1401 may be determined as the dominant eye, and the user's left eye 1402 may be determined as the non-dominant eye.
According to an embodiment, the fourth region 1414 may be defined as a region in which dominance of the user's right eye 1401 or left eye 1402 is ignored. For example, when the user looks at an object located in the fourth region 1414, it may be difficult to determine the dominant eye and/or non-dominant eye because the position of the object is too close to the user's face.
The area of the field of view for recognizing things is divided into four regions in
According to certain embodiments, the electronic device 101 may identify the dominant eye and/or non-dominant eye based on the user's left and right eyes, and may, among the first display panel corresponding to the left eye and the second display panel corresponding to the right eye, change the settings of the display panel corresponding to the identified non-dominant eye to be at least partially different from the settings of the display panel corresponding to the identified dominant eye. For example, the electronic device 101 may at least partially change the settings of the display panel corresponding to the non-dominant eye so as to lower the display performance of this display panel.
A method according to certain embodiments may include: identifying, using one or more of a first camera (e.g., distance measuring camera 315 in
According to an embodiment, identifying the dominant eye and non-dominant eye may include: measuring a distance to an object using the first camera; identifying the gaze directions of the left eye and the right eye by using the second camera 313 based on determining that the measured distance exceeds a threshold value; and identifying the dominant eye and non-dominant eye from among the left eye and the right eye based on the captured gaze directions.
According to an embodiment, changing the settings of the dominant display panel may include: determining whether the brightness value measured using an illuminance sensor (e.g., illuminance sensor 322 in
The method according to an embodiment may further include: detecting movement of an object to which the gaze of the user is directed based on the gaze direction; determining whether the movement of the object exceeds a preset reference value; and reducing a frame rate of the non-dominant display panel corresponding to the non-dominant eye based on determining that the movement exceeds the reference value.
The method according to an embodiment may further include: determining whether the dominant eye is changed based on detection of a left-eye gaze direction and a right-eye gaze direction; based on determining that the dominant eye is changed from the right eye to the left eye, changing at least some of the settings of the display panel corresponding to the right eye; and based on determining that the dominant eye is changed from the right eye to the left eye, reverting the settings of the display panel corresponding to the left eye to initial settings.

As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd,” or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with,” “coupled to,” “connected with,” or “connected to” another element (e.g., a second element), it means that the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.
As used in connection with certain embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, “logic,” “logic block,” “part,” or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).
Certain embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101). For example, a processor (e.g., the processor 120) of the machine (e.g., the electronic device 101) may invoke at least one of the one or more instructions stored in the storage medium, and execute it, with or without using one or more other components under the control of the processor. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked. The one or more instructions may include a code generated by a complier or a code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term “non-transitory” simply means that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to an embodiment, a method according to certain embodiments of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., PlayStore™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to certain embodiments, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities, and some of the multiple entities may be separately disposed in different components. According to certain embodiments, one or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In such a case, according to certain embodiments, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. According to certain embodiments, operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
The embodiments of the present disclosure and the accompanying drawings are only examples in order to easily describe the present disclosure and facilitate comprehension of the present disclosure, but are not intended to limit the present disclosure. Therefore, in addition to the embodiments disclosed herein, the present disclosure should be construed to include all modifications or modified forms drawn based on the present disclosure and is defined by the appended claims and their equivalents.
