Abstract

Methods and apparatus are provided for an adaptive display lockout system. The apparatus comprises means for monitoring user initiated display changes with a device having a display and one or more inputs, means for comparing the user initiated display changes to a display lockout criteria, and means for temporarily disabling the display if the user initiated display changes meets or exceeds the display lockout criteria.

Claims

1. An adaptive display lockout system, comprising:

means for monitoring user initiated display change requests directed to a device having a display;

means for comparing the user initiated display change requests to a display lockout criteria; and

means for temporarily disabling the display if the user initiated display change requests meets or exceeds the display lockout criteria.

2. The system of claim 1, wherein the display lockout criteria includes one or more software calibrations.

3. The system of claim 2, wherein device further includes one or more inputs and each of the one or more software calibrations correspond to a display lockout level associated with each of the one or more inputs.

4. The system of claim 2, wherein each of the one or more software calibrations include a user event counter, a user event timer and a display lockout time.

5. The system of claim 4, wherein the user event counter ranges from 0 and 64.

6. The system of claim 4, wherein the user event timer ranges from 0 to 25.5 seconds.

7. The system of claim 4, wherein the display lockout time period ranges from 0 to 16 seconds.

8. The system of claim 4, wherein each of the one or more software calibrations further includes means for signaling the end of the display lockout time period.

9. The system of claim 8, wherein means for signaling the end of the display lockout time period is an auditory cue.

10. The system of claim 1, wherein the display is blank when disabled.

11. The system of claim 1, wherein the display includes a warning message when disabled.

12. The system of claim 1, further comprising means for resuming the display.

13. A method of adaptively locking out a display on a vehicle device based on user interaction, comprising:

counting the number of user initiated display changes with an event counter;

timing the number of user initiated display changes with an event timer;

comparing the number of user initiated display changes in the event counter and event timer to a display lockout criteria; and

disabling the display for a display lockout time period if the event counter and event timer information meets or exceeds the display lockout criteria.

14. The method of claim 13, wherein the display lockout criteria includes a number of allowed user initiated display changes in a preset time period

15. The method of claim 13, further comprising signaling the end of the display lockout time period.

16. The method of claim 15, wherein the signaling the end of the display lockout time period is an auditory cue.

17. The method of claim 13, further comprising informing the user that the display is not available during the display lockout time period.

18. A vehicle audio/visual device capable of adaptively locking out a display based on user interaction, comprising:

a user interface on the device for processing user initiated display changes;

an event counter coupled to the user interface and configured to count a number of user initiated display changes originating from the user interface;

an event timer coupled to the event counter and configured to measure a time period for the number of user initiated display changes; and

a processor coupled to the event timer and configured to disable the display for a display lockout time period if the number of user initiated display changes in the time period exceeds an allowed number of user initiated display changes in a preset time period.

19. The device of claim 18, further comprising an audible signal configured to indicate the end of the display lockout time period.

20. The device of claim 18, wherein the display lockout time period ranges from 0 to 16 seconds.
