Abstract

Certain embodiments relate to systems and methods for presenting a stereoscopic, 3-dimensional image to a user. The system may comprise a mobile device having a camera and a pixel-selective mask overlaying a display. The system may perform facial and object recognition techniques to determine the location of the user's eyes. Subsequently, the system may adjust the mask so as to maintain an optimal stereoscopic effect for the user, regardless of the user's position.

First claim

What is claimed is:

1. A computer-implemented method for rendering a stereoscopic effect for a user, the method comprising:
receiving an image, the image containing a portion of the user's face;
determining a width between the user's eyes based on the image;
determining a relative distance from the user's eyes to a 3D display based on the determined width; and
moving a stereoscopic focus position from a first position to a second position by adjusting a distance of a mask to the 3D display based on (i) the determined relative distance, (ii) the determined width, and (iii) at least one of gyroscopic and acceleration information indicative of variations in a relative position of the 3D display with respect to the user, the relative position of the 3D display with respect to the user being different from the determined relative distance, wherein adjusting the distance of the mask to the 3D display comprises adjusting the mask such that movement of the mask is a scaled percentage of movement of the user's face, the user's eyes, or both.

2. The method of claim 1 , wherein the second position corresponds to a location of the user's eyes.

3. The method of claim 1 , wherein the first position is further from the 3D display than the second position and adjusting the distance of the mask will comprises moving the mask closer to the 3D display.

4. The method of claim 1 , wherein adjusting the distance of the mask further comprises modifying a distance between separations within the mask.

5. The method of claim 1 , wherein determining the relative distance is based on the image.

6. The method of claim 1 , wherein determining the relative distance comprises retrieving location information from a memory.

7. A device for rendering a stereoscopic effect for a user, the device comprising:
a camera;
a display configured to display a stereoscopic image pair;
a mask over the display; and
a control module configured to
receive an image from the camera, the image containing a portion of the user's face;
determine a width between the user's eyes based on the image;
determine a relative distance from the user's eyes to the display based on the determined width; and
move a stereoscopic focus position from a first position to a second position by adjusting a distance of the mask to the display based on (i) the determined relative distance, (ii) the determined width, and (iii) at least one of gyroscopic and acceleration information indicative of variations in a relative position of the display with respect to the user, the relative position of the display with respect to the user being different from the determined relative distance, wherein adjusting the distance of the mask to the display comprises adjusting the mask such that movement of the mask is a scaled percentage of movement of the user's face, the user's eyes, or both.

8. The device of claim 7 , wherein the second position corresponds to a location of the user's eyes.

9. The device of claim 7 , wherein the first position is further from the display than the second position and adjusting the distance of the mask comprises moving the mask closer to the display.

10. The device of claim 7 , wherein adjusting the mask further comprises modifying a distance between separations within the mask.

11. The device of claim 7 , wherein determining the relative distance is based on the image.

12. The device of claim 7 , further comprising a memory, and wherein determining the relative distance comprises retrieving location information from the memory.

13. A non-transitory computer-readable medium having stored thereon instructions that, when executed, cause a processor of a device to:
receive an image, the image containing a portion of the user's face;
determine a width between the user's eyes based on the image;
determine a relative distance from the user's eyes to a 3D display based on the determined width; and
move a stereoscopic focus position from a first position to a second position by adjusting a distance of a mask to the 3D display based on (i) the determined relative distance, (ii) the determined width, and (iii) at least one of gyroscopic and acceleration information indicative of variations in a relative position of the 3D display with respect to the user, the relative position of the 3D display with respect to the user being different from the determined relative distance, wherein adjusting the distance of the mask to the 3D display comprises adjusting the mask such that movement of the mask is a scaled percentage of movement of the user's face, the user's eyes, or both.

14. The non-transitory computer-readable medium of claim 13 , wherein the second position corresponds to a location of the user's eyes.

15. The non-transitory computer-readable medium of claim 13 , wherein the first position is further from the 3D display than the second position and adjusting the distance of the mask comprises moving the mask closer to the 3D display.

16. The non-transitory computer-readable medium of claim 13 , wherein the adjusting of the mask further comprises modifying a distance between separations within the mask.

17. The non-transitory computer-readable medium of claim 13 , wherein the determining of the relative distance from the user's eyes to the 3D display is based on the image.

18. The non-transitory computer-readable medium of claim 13 , wherein the determining of the relative distance from the user's eyes to the 3D display comprises retrieving location information from a memory.

19. A device for rendering a stereoscopic effect for a user, the device comprising:
a camera;
means for displaying a stereoscopic image pair;
means for masking the means for displaying; and
means for receiving an image from the camera, the image containing a portion of the user's face;
means for determining a width between the user's eyes based on the image;
means for determining a relative distance from the user's eyes to the means for displaying based on the determined width; and
means for moving a stereoscopic focus position from a first position to a second position by adjusting a distance of the masking means to the means for displaying based on (i) the determined relative distance, (ii) the determined width, and (iii) at least one of gyroscopic and acceleration information indicative of variations in a relative position of the means for displaying with respect to the user, the relative position of the 3D display with respect to the user being different from the determined relative distance, wherein adjusting the distance of the masking means to the means for displaying comprises adjusting the masking means such that movement of the masking means is a scaled percentage of movement of the user's face, the user's eyes, or both.

20. The device of claim 19 , wherein the means for displaying comprises a display, the means for masking comprises a mask, the means for receiving comprises a software module, the means for determining the relative distance from the user's eyes to the means for displaying comprises a software module, the means for determining the width between the user's eyes comprises a software module, and the means for moving comprises a software module configured to operate an actuator.

21. The device of claim 19 , wherein the second position corresponds to a location of the user's eyes.

22. The device of claim 19 , wherein the first position is further from the means for displaying than the second position and adjusting the distance of
