Abstract
Official abstract text for this publication.
The present invention provides a touch sensor system which is capable of removing a hand-placing signal while mounting normal application software on a host device. A touch sensor system ( 1 ) includes a hand-placing removing process section ( 2 ) which detects a hand-placing region on a basis of strengths of capacitance signals, each strength being indicative of a change in capacitance and which replaces values of capacitance signals corresponding to respective capacitors provided in the detected hand-placing region with a nil value indicative of a state where not touch input is made.
First claim
Opening claim text (preview).
The invention claimed is: 1. A touch sensor system, comprising: detection means for detecting a hand-placing region which is a region of a touch panel including a plurality of capacitors provided in a matrix manner and on which region a hand is placed in order to make an input with a stylus, said detecting being based on strengths of capacitance signals, each strength being indicative of a change in the corresponding capacitor; replacing means for replacing values of capacitance…
