Abstract

Methods and apparatuses are provided for configuring a screen of an electronic device. A first object, corresponding to a left eye of a user of the electronic device, and a second object, corresponding to a right eye of the user, are displayed on the screen. A threshold distance is obtained, which is one of a minimum distance and a maximum distance between the first object and the second object at which an image, corresponding to the first object and the second object, is properly viewed by the user. An interpupillary distance (IPD) is determined between the first eye and the second eye based on the threshold distance.

Claims

1. A method for configuring a screen of an electronic device, the method comprising:

displaying, on the screen, a first object, corresponding to a left eye of a user of the electronic device, and a second object, corresponding to a right eye of the user;

obtaining a threshold distance, which is one of a minimum distance and a maximum distance between the first object and the second object for forming an image corresponding to the first object and the second object; and

determining an interpupillary distance (IPD) between the first eye and the second eye based on the threshold distance.

2. The method of claim 1, further comprising obtaining a distance adjustment command enabling adjustment of the distance between the first object and the second object.

3. The method of claim 2, further comprising adjusting and displaying the distance between the first object and the second object based on the distance adjustment command.

4. The method of claim 3, further comprising setting a size of each of the first object and the second object to a readjusted size based on a virtual reality (VR) application, and displaying the first object and the second object with the readjusted size.

5. The method of claim 1, wherein determining the IPD comprises:

obtaining a standard IPD and a standard threshold distance; and

determining the IPD based on the standard IPD, the standard threshold distance, and the threshold distance.

6. The method of claim 1, further comprising displaying a VR object based on the determined IPD.

7. The method of claim 1, further comprising updating an IPD value of a VR application based on the determined IPD.

8. The method of claim 1, further comprising displaying a grid-shaped reference object proximate to the image.

9. The method of claim 1, further comprising displaying two cross-shaped (+) objects respectively corresponding to the left eye and the right eye.

10. The method of claim 1, further comprising storing user identification information and the IPD in association with each other.

11. An electronic device, comprising:

a display configured to display a first object, corresponding to a left eye of a user of the electronic device, and a second object, corresponding to a right eye of the user; and

a controller configured to obtain a threshold distance, which is one of a minimum distance and a maximum distance between the first object and the second object for forming an image corresponding to the first object and the second object, and determine an interpupillary distance (IPD) between the first eye and second eye based on the threshold distance.

12. The electronic device of claim 11, whether the controller is further configured to obtain a distance adjustment command enabling adjustment of the distance between the first object and the second object.

13. The electronic device of claim 12, wherein the controller is further configured to control the display to adjust and display the distance between the first object and the second object based on the distance adjustment command.

14. The electronic device of claim 13, wherein the controller is further configured to control the display to set a size of each of the first object and the second object to a readjusted size based on a virtual reality (VR) application, and to display the first object and the second object with the readjusted size.

15. The electronic device of claim 11, wherein the controller is further configured to obtain a standard IPD and a standard threshold distance, and determine the IPD based on the standard IPD, the standard threshold distance, and the threshold distance.

16. The electronic device of claim 11, wherein the controller is further configured to control the display to display a VR object based on the determined IPD.

17. The electronic device of claim 11, wherein the controller is further configured to update an IPD value of a VR application based on the determined IPD.

18. The electronic device of claim 11, wherein the display is further configured to display a grid-shaped reference object proximate to the image.

19. The electronic device of claim 11, wherein the display is further configured to display two cross-shaped (+) objects respectively corresponding to the left eye and the right eye.

20. A computer-readable storage medium storing a virtual reality (VR) application including a first interpupillary distance (IPD), the VR application:

displaying, on a screen of an electronic device, a first object, corresponding to a left eye of a user of the electronic device, and a second object, corresponding to a right eye of a user of the electronic device;

obtaining a threshold distance, which is one of a minimum distance and a maximum distance between the first object and the second object for forming an image corresponding to the first object and the second object;

determining a second IPD between the first eye and the second eye based on the threshold distance;

updating the first IPD to the second IPD; and

displaying a VR object based on the second IPD.
