Abstract

A method, apparatus, user interface and computer program product include the ability to determine a brightness characteristic of a display, use the brightness characteristic to determine a minimum and optimum font size for information displayed on the display, and automatically adjust the displayed information such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller that the optimum font size.

Claims

1. A method comprising:

determining a brightness characteristic of a display;

determining a minimum and optimum font size for information displayed on the display from the brightness characteristic from a table; and

automatically adjusting the displayed information on the display using a module such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller that the optimum font size.

2. The method of claim 1, further comprising determining a brightness characteristic of the display from contrast settings from a display driver.

3. The method of claim 1, further comprising using a controller to determine the brightness characteristic of the display from a content of the display.

4. The method of claim 1, further comprising determining a brightness characteristic of the display using a sensor.

5. The method of claim 1, further comprising scaling other fonts in the information in relation to the minimum and optimum font sizes using the module.

6. The method of claim 1, further comprising using the brightness characteristic to determine the minimum and optimum font size according to a user selected minimum and optimum font size stored in a table.

7. The method of claim 1, further comprising using the brightness characteristic to determine the minimum and optimum font size according to a user'"'"'s vision characteristics stored in a table.

8. The method of claim 1, further comprising using the brightness characteristic to determine the minimum selected minimum and optimum font size according to a user'"'"'s age stored in a table.

9. The method of claim 1, further comprising using a manual control for manually adjusting font sizes of the displayed information after the automatic adjustment.

10. A computer program product comprising a computer readable storage medium configured to execute the method according to claim 1.

12. The apparatus of claim 10, wherein the device comprises a display driver configured to provide contrast settings of the display for determining the brightness characteristic.

13. The apparatus of claim 10, wherein the device comprises a display driver configured to provide the brightness characteristic from a content of the display.

14. The apparatus of claim 10, wherein the device comprises a sensor for sensing the brightness characteristic.

15. The apparatus of claim 10, wherein the module is further configured for scaling other fonts in the information in relation to the minimum and optimum font sizes.

16. The apparatus of claim 10, further comprising a user configuration settings table for additionally determining the minimum and optimum font size according to a user selected minimum and optimum font size.

17. The apparatus of claim 10, further comprising a user configuration settings table for additionally determining the minimum and optimum font size according to a user'"'"'s vision characteristics.

18. The apparatus of claim 10, further comprising a user configuration settings table determine the minimum selected minimum and optimum font size according to a user'"'"'s age.

19. The apparatus of claim 10, further comprising an input device configured for manually adjusting font sizes of the displayed information after the automatic adjustment.

11. An apparatus comprising:

a device configured for determining a brightness characteristic of a display;

a module configured for determining a minimum and optimum font size for information displayed on the display using the brightness characteristic; and

the module further configured for adjusting the displayed information such that a size of a smallest font of the information is not smaller than the minimum font size and that a size of a main font of the information is not smaller that the optimum font size.

20. A user interface comprising:

a display having a brightness characteristic;

a module configured for determining a minimum and optimum font size for information for presentation on the display using the brightness characteristic, and for adjusting the information such that a smallest font size of the information is not smaller than the minimum font size and a main font size of the information is not smaller that the optimum font size.
