Abstract: A wearable device and a method of indicating a hygiene status on a wearable device. The method may include obtaining a first gesture signal using an inertial sensor in the wearable device and matching the first gesture signal to one of a plurality of gesture signal patterns stored in the wearable device and associated with a multi-stage gesture. It may further include obtaining another gesture signal and matching it to another of the plurality of gesture signal patterns. It may then include determining, based on detecting at least two of the gestures in the multi-stage gesture that the multi-stage gesture has been completed and, as a result, setting the hygiene status to a clean state. The device may output a sensory signal using an output device indicating the clean state.
