Dual sensor touchscreen with projective capacitive sensors and force sensors

摘要

A method of operating a touchscreen system, comprising the steps of: detecting (1103) a force applied to a touchscreen of said touchscreen system with at least one force sensor, wherein said detected force corresponds to a touch of said touchscreen; confirming (1105) said touch of said touchscreen detected by said at least one force sensor with a projective-capacitive sensor; determining (1113) if said touchscreen system is operating in a drag mode; generating (1115) a set of position coordinates corresponding to said touch by said projective-capacitive sensor if said touchscreen system is operating in said drag mode; and transmitting said set of position coordinates to a touchscreen operating system. The invention also provides a dual sensor touchscreen system for carrying out the method.
