Abstract

See full text

An combination interpolating force sensitive resistor (IFSR) array touch sensor and capacitive touch sensor, or a modified IFSR sensor, is configured to detect touches resistively and capacitvely. By comparing resistive and capacitive signals, touches may be accurately characterized. The IFSR array may also be used in conjunction with an active stylus to determine a position of the active stylus relative to the IFSR array.
