Method and apparatus for analyzing capacitive EMG and IMU sensor signals for gesture control

摘要

There is disclosed a muscle interface device for use with controllable connected devices. In an embodiment, the muscle interface device comprises a sensor worn on the forearm of a user, and the sensor is adapted to recognize a plurality of gestures made by a user to interact with a controllable connected device. The muscle interface device utilizes a plurality of sensors, including one or more of capacitive EMG sensors and an IMU sensor, to detect gestures made by a user. Other types of sensors including MMG sensors may also be used. The detected user gestures from the sensors are processed into a control signal for allowing the user to interact with content displayed on the controllable connected device.

1. An apparatus to detect and analyze signals for gesture control, comprising:
a band to be worn by a user; a plurality of electromyography (EMG) sensors positioned radially around a circumference of the band, each EMG sensor in the plurality of EMG sensors to detect -electrical signals produced by muscle activity in response to the user performing a gesture; an inertial sensor carried by the band, the inertial sensor to detect motion in response to the user performing the gesture; and a processor carried by the band, the processor communicatively coupled to receive EMG signals from the plurality of EMG sensors and inertial sensor signals from the inertial sensor, and which in use: analyzes the EMG signals and recognizes the gesture performed by the user based on the analysis of the EMG signals, and analyzes the inertial sensor signals and determines a motion aspect of the gesture based on the analysis of the inertial sensor signals.
