Dual sensor touchscreen system and method of operating one

摘要

A touchscreen system, comprising at least one force sensor (401-404) coupled to a touchscreen of said touchscreen system, said force sensor (401-404) monitoring a force component associated with a touch of said touchscreen; a projective-capacitive sensor system (503...) coupled to said touchscreen (405); and a processor (701) coupled to said at least one force sensor (401-404) and said projective-capacitive sensor system (503...), wherein said processor (701) calculates a set of position coordinates associated with said touch when said force component is greater than a force threshold, said set of position coordinates determined by said projective-capacitive sensor system (503...). The invention also provides a method of operating a touchscreen.
