Abstract

Systems and methods to provide automatic adjustment of font on a visual display are described. In an example system, a vision properties module accesses data stored in a vision record describing one or more vision states of a user of a mobile device. A distance module determines a distance between the user and the mobile device. A display modification module modifies a visual display of the user interface based on a current vision state of the one or more vision states of the user and the distance.

Claims

1. A system comprising:

a vision properties module to access data stored in a vision record describing one or more vision states of a user of a mobile device;

a distance module to determine a distance between the user and the mobile device; and

a display modification module to, using one or more processors, modify a visual display of the user interface based on a current vision state of the one or more vision states of the user and the distance.

2. The system of claim 1, wherein the vision state of the user is based on an eyeglass prescription prescribed to the user.

3. The system of claim 1, wherein the current vision state of the user is affected by presbyopia.

4. The system of claim 1, wherein the current vision state of the user is affected by myopia.

5. The system of claim 1, wherein the vision properties module is further to determine the current vision state.

6. The system of claim 1, wherein the vision properties module is further to augment the vision record based on the user'"'"'s viewing habits or preferences.

7. The system of claim 1, wherein the vision properties module is further to provide an alert interface to receive a selection of the current vision state.

8. The system of claim 1, wherein the vision properties module is further to determine the current vision state by identifying glasses worn by the user.

9. The system of claim 1, wherein the vision properties module is further to determine the current vision state based on habits of the user.

10. The system of claim 1, wherein the distance module is to determine the distance using an infrared sensor of the mobile device.

11. The system of claim 1, wherein the distance module is to determine the distance based on a relative size of a facial feature from an image captured by a camera of the mobile device.

12. The system of claim 1, further comprising a motion module to measure movement of the mobile device relative to a previous position using an internal accelerometer.

13. The system of claim 1, wherein the display modification module is to modify the visual display of the user interface by increasing a font size to a predetermined level.

14. The system of claim 13, wherein the predetermined level is based in part on movement of the mobile device.

15. The system of claim 1, wherein the display modification module is to modify the visual display of the user interface by exhibiting the properties of a lens.

16. The system of claim 1, wherein the lens is concave.

17. The system of claim 1, wherein the lens is convex.

18. The system of claim 1, wherein the display modification module is to modify the visual display of the user interface based on color-blindness of the user.

19. A method comprising:

accessing data stored in a vision record describing one or more vision states of a user of a mobile device;

determining a distance between the user and the mobile device; and

using one or more processors, modifying a visual display of the user interface based on a current vision state of the one or more vision states of the user and the distance.

20. A non-transitory computer-readable medium having instructions embodied thereon, the instructions executable by one or more processors to perform a method comprising:

accessing data stored in a vision record describing one or more vision states of a user of a mobile device;

determining a distance between the user and the mobile device; and

modifying a visual display of the user interface based on a current vision state of the one or more vision states of the user and the distance.
