Patent ID: 11797086

Abstract:
A method of controlling a wearable tap detection system having a processor and a plurality of sensors for detecting contact by one or more fingers against a surface, including at least one mechanical sensor, includes detecting, as a tap event, a signal from the at least one mechanical sensor that exceeds a predetermined threshold. When the tap event is detected, the processor is switched from a first power mode to a second power mode, the second power mode using more power than the first power mode. Then, using the processor in the second power mode, processing of one or more signals from the plurality of sensors is performed to generate processed signal data. After the processed signal data is generated, the processor is switched from the second power mode to the first power mode. Then, while in the first power mode that uses less power, the processor analyzes the processed signal data to determine one of a character or a command that corresponds to the fingers that contacted the surface at the time of the tap event.
