CREATION OF VIRTUAL INTERSECTION POINTS ON A TOUCHSCREEN TO PERMIT STATIC, NON SWIPING FINGERPRINT USER AUTHENTICATION

摘要

A method for operating a two-dimensional touch array by providing virtual grid intersections. The techniques may be used to improve the array resolution. It may also be used to detect fingerprint ridge and valley detail even when the finger is not moving, and when the array node spacing is much greater than the ridge and valley spacing.
