TOUCH LOCATION DETERMINATION WITH ERROR CORRECTION FOR SENSOR MOVEMENT

Touch location determination is enhanced by correcting for errors that arise due to touch panel movement. A touch sensitive device includes a capacitive touch sensor configured to generate signals indicative of a location of a capacitively coupled touch on a touch surface. An error correction sensor...

Summary:Touch location determination is enhanced by correcting for errors that arise due to touch panel movement. A touch sensitive device includes a capacitive touch sensor configured to generate signals indicative of a location of a capacitively coupled touch on a touch surface. An error correction sensor generates a signal associated with movement of the capacitive touch sensor. Touch location is determined using the touch location signals and the error signal.
