Glove touch detection

Abstract:

An electronic device including a touch screen or touch sensor panel can operate in a bare finger touch detection mode or a glove touch detection mode. While operating in the bare finger touch detection mode, in response to detecting a signal density slope corresponding to a gloved object touching the panel and lifting off without re-approaching the panel within a predetermined time or in response to detecting a signal density slope corresponding to a gloved object touching the panel continuously for a predetermined period of time, the electronic device can transition from the bare finger mode to the glove touch mode, for example. While in the glove touch detection mode, the electronic device can transition to the bare finger touch detection mode in response to detecting a touch signal density that exceeds a predetermined threshold or in response to detecting a touch signal that exceeds a predetermined threshold.
