Abstract

A system and method adjusts the viewing angle of a display based on user input and/or automatically based on content and/or detected viewers. The viewing angle changes may be limited to certain portions of the display or the whole display. The system and method may change viewing angles in different direction separately and independently.

Claims

1. A computer implemented method for securely displaying content, the method comprising:

identifying a first portion of an image separate and different from a second portion of the image;

determining a location of first pixels associated with the first portion of the image on a display; and

in response to determining the location of the first pixels, causing the display to adjust a viewing angle from the first pixels associated with the first portion of the image without adjusting the viewing angle from second pixels associated with the second portion of the image, the viewing angle being adjusted by retracting or extending one or more louvers associated with the first pixels.

2. The method of claim 1, wherein identifying the first portion of the image comprises determining that the first portion of the image delineates a data entry field.

3. The method of claim 1, wherein identifying the first portion of the image comprises determining a type of content in the first portion of the image.

4. The method of claim 1, wherein causing the display to adjust the viewing angle comprises:

determining a first viewer associated with a device coupled with the display;

detecting a second viewer; and

determining that the second viewer is an unintended viewer of the content.

5. The method of claim 4, further comprising causing the display to return the viewing angle from the first pixels associated with the first portion of the image to a previous viewing angle when the unintended viewer has been detected as leaving a viewing area of the display.

6. The method of claim 4, wherein the viewing angle renders the content unviewable by the second viewer.

7. The method of claim 4, wherein determining the second viewer is an unintended viewer of the content is based at least on the content, location of the display, and information about the second viewer.

8. The method of claim 4, wherein determining the second viewer is an unintended viewer comprises identifying the second user and determining a relationship between the second viewer and the first viewer.

9. A screen privacy system, comprising:

a non-transitory memory storing executable instructions; and

one or more hardware processors coupled to the non-transitory memory and configured to read the executable instructions to cause the system to perform operations comprising;

receiving a request to adjust a viewing angle of a display device in a first direction; and

in response to the request, causing the display device to adjust the viewing angle of the display device in the first direction by retracting or extending one or more louvers.

10. The system of claim 9, wherein the operations further comprise receiving a request to adjust the viewing angle of the display device in a second direction and causing the display device to adjust the viewing angle of the display device in the second direction in response.

11. A screen privacy system comprising:

a non-transitory memory storing executable instructions; and

one or more hardware processors coupled to the non-transitory memory and configured to read the executable instructions to cause the system to perform operations comprising;

capturing an image of a user using an image sensor;

conducting facial recognition on the image; and

adjusting a viewing angle of a display based on the position of a face recognized in the image by retracting or extending one or more louvers.

12. The system of claim 11, wherein the operations further comprise determining an angle of the face in relation to the image sensor based at least in part on the location of the face in the image.

13. The system of claim 11, wherein the viewing angle is adjusted based on the determined angle.

14. The system of claim 13, wherein the adjusted viewing angle is greater than or equal to the determined angle.

15. The system of claim 11, wherein the operations further comprise determining whether the face recognized in the image matches an identity associated with a user.

16. The system of claim 15, wherein the adjusted viewing angle is more acute when the face recognized in the image does not match an identity associated with the user.

17. The system of claim 15, wherein the adjusted viewing angle is more obtuse when the face recognized in the image does match an identity associated with the user.

18. The system of claim 11, wherein adjusting the viewing angle comprises adjusting one or more micro-louvers.

19. The system of claim 18, wherein adjusting one or more micro-louvers comprises extending or retracting the one or more micro-louvers.
