1. 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 that is separate from the wearable tap detection system, including at least one mechanical sensor, the method comprising:
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, switching the processor from a first power mode to a second power mode, the second power mode using more power than the first power mode;
performing, using the processor in the second power mode, processing of one or more signals from the plurality of sensors to generate processed signal data;
switching the processor from the second power mode to the first power mode, after the processed signal data is generated; and
performing, using the processor in the first power mode, analysis of 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.
