US Patent 10001843 Modular sensing device implementing state machine gesture interpretation

A modular sensing device can include an inertial measurement unit to generate sensor data corresponding to user gestures performed by a user, a mode selector enabling the user to select a mode of the modular sensing device out of a plurality of modes, and one or more output devices to generate output based on the user gestures and the selected mode. The modular sensing device can further include a controller to implement a plurality of state machines. Each state machine can be associated with a corresponding user gesture by a sensor data signature. The state machine can execute a state transition when the sensor data matches the sensor data signature. The executed state transition can cause the controller to generate a corresponding output via the one or more output devices specific to the selected mode and based on the corresponding user gesture.
