Abstract

See full text

A system for delineating a location of a virtual button by haptic feedback includes a cover layer, a touch-input sub-system, a haptic transducer, and a haptic controller. The touch-input sub-system includes force-measuring and touch-sensing integrated circuits (FMTSICs), each coupled to the inner surface of the cover layer corresponding to one of the virtual buttons. The touch-input sub-system is configured to determine: (1) supplemental haptic feedback commands if “PMUT Triggered” Boolean data is True for at least one of the FMTSICs (Touched FMTSICs) and light-force conditions are satisfied for all of the Touched FMTSICs, and (2) primary touch inputs if “PMUT Triggered” Boolean data is True for at least one of the FMTSICs (Touched FMTSICs) and light-force conditions are not satisfied for at least one of the Touched FMTSICs. The haptic controller is configured to drive the haptic transducer to generate haptic feedback in accordance with the supplemental haptic feedback commands.
