Abstract
It is an object of the present invention to provide an apparatus and method for emulating touch and gesture events on a capacitive touch sensor array comprising: an electric field detection means for measuring the electric field intensity emitted as a function of time from a plurality of scan electrodes of said capacitive touch sensor array; and an electric field synthesizing means to create time variant electric fields coincident to electric fields emitted from said plurality of scan electrodes; and a capacitive coupling means to couple said synthesized electric fields to said plurality of electrodes inducing voltages which emulate time sequential touch events at said plurality of emulated touch locations animating said emulated gesture movement.
