Method for resetting configuration on a touchscreen interface
First Claim
1. A method of resetting calibration on a touchscreen interface system having a processor, the processor programmed to perform the method comprising:
- upon system startup, using stored factory calibration settings for determination of touch locations on the touchscreen;
determining if a screen touch has occurred during system startup initiation;
prompting a user to interact with the touchscreen to reset calibration to the stored factory calibration settings if a screen touch has occurred during system startup initiation;
selecting stored existing user calibration settings if a screen touch has not occurred during system startup initiation; and
selecting the stored factory calibration settings based upon interaction of the user with the touchscreen in response to the prompting.

Abstract
Factory settings of a touchscreen interface may be restored by cycling power off and on to initiate system startup while simultaneously touching the touchscreen. If a screen touch is in progress at system startup, the user is prompted to discontinue the screen touch, and then is prompted to touch the screen again before a timer expires in order to restore factory calibration settings. If there is no screen touch upon startup, or if the user does not touch the screen to restore factory settings within the timer period, existing user calibration is loaded, and the application is allowed to run with the user calibration settings.

6. A method of resetting calibration of a touchscreen interface system having a processor, the processor programmed to perform the method comprising:
-
cycling power off and on to initiate system startup; detecting a first screen touch while system startup is being initiated, using stored factory calibration settings; prompting a user to discontinue the first screen touch; prompting the user to produce a second screen touch to select the factory calibration settings; selecting the factory calibration settings for use in determining screen touch locations if the second screen touch is detected; and selecting stored user calibration settings for use in determining screen touch locations if either the first screen touch or the second screen touch is not detected. - View Dependent Claims (7, 8, 9, 10, 11)
