Enhanced touch technology for hand writing: finger, palm and stylus discrimination

摘要

Stantum's unique Interpolated Voltage Sensing Matrix~1 (or iVSM) technology enables 10 simultaneous touches combined to handwriting input. Unlike other technologies, fingers and passive stylus input can be achieved simultaneously to provide pen-and-paper experience. However, performing the discrimination between finger, palm and stylus was still an insuperable technology step. This paper is focused on recent progresses in the touch sensor structure which allows natural and transparent handwriting input on a display
