1. An adaptive display lockout system, comprising:
- means for monitoring a number of user initiated display change requests for a preset time interval, wherein the user initiated display change requests are directed to a device having a display, and wherein each user initiated display change request represents a request to change visual information on the display;
means for comparing the number of user initiated display change requests to a display lockout criteria, wherein the display lockout criteria corresponds to an allowable number of user initiated display change requests for the preset time interval; and
means for temporarily disabling the display for a display lockout time if the number of user initiated display change requests meets the display lockout criteria.

Abstract
Methods and apparatus are provided for adaptively locking out a display on a vehicle device based on user interaction. A method begins by counting a number of user initiated display changes with an event counter, and timing the user initiated display changes with an event timer. The method continues by comparing the number of user initiated display changes in the event counter to an allowable number of user initiated display changes corresponding to the time in the event timer, and disabling the display for a display lockout time period if the number of user initiated display changes exceeds the allowable number of user initiated display changes.

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 the event counter, the processor being configured to; compare the number of user initiated display changes in the event counter to an allowed number of user initiated display changes corresponding to the time in the event timer; and disable the display for a display lockout time period if the number of user initiated display changes in the time period exceeds the allowed number of user initiated display changes. - View Dependent Claims (19, 20)
