US Patent 10216274 Systems, articles, and methods for wearable human-electronics interface devices

Systems, articles, and methods for wearable human-electronics interfaces are described. A wearable human-electronics interface device includes a band that in use is worn on an appendage (e.g., a wrist, arm, finger, or thumb) of a user. The band carries multiple sensors that are responsive to vibrations. The sensors are physically spaced apart from one another on or within the band. The band also carries an on-board processor. The sensors detect vibrations at the appendage of the user when the user performs different finger tapping gestures (i.e., tapping gestures involving different individual fingers or different combinations of fingers) and provide corresponding vibration signals to the processor. The processor classifies the finger tapping gesture(s) based on the vibration signals and an on-board transmitter sends a corresponding signal to control, operate, or interact with a receiving electronic device. The sensors include inertial sensors, digital MEMS microphones, or a combination thereof.
