Abstract:
A method for calibrating an Acoustic Pulse Recognition (APR) touchscreen comprises touching an APR touchscreen at N comparison touch points. N audio profiles are acquired, and each of the N audio profiles are associated with one of the N comparison touch points. A predetermined calibration file is selected based on the N audio profiles. The predetermined calibration file comprises audio profiles associated with coordinate locations on the touchscreen.
