Use of dynamically scaled linear correction to improve finger tracking linearity on touch sensors

摘要

A system and method for correcting non-linear tracking of objects that may change size when moving on a large touch sensor having a relatively large space between electrodes by dynamic compensating on-the-fly by constantly calculating the size of a finger as measured by the touch sensor, and then scaling that measured size so that look-up tables may be used to compensate for any size finger in the X and Y axes.
