User Interface Control of Responsive Devices

Abstract

A system and method for detecting and interpreting tissue electrical signals from a user. The system comprises a user interface device configured to be worn at a wrist of a user, the user interface device comprising biopotential sensors configured to detect tissue electrical signals from the user, the biopotential sensors providing at least two channels of tissue electrical signals. The system includes a processor and is configured to receive the tissue electrical signals from the at least two channels, analyze the tissue electrical signals, and detect that a signal from at least one channel exceeds a threshold. Based on detecting that the signal exceeds the threshold, the system determines that a gesture has been performed by the user and generates an output corresponding to the determined gesture for a responsive device. The method includes receiving tissue electrical signals from the biopotential sensors, analyzing the signals, detecting threshold exceedance, determining that a gesture has been performed, and generating an output for a responsive device. The threshold is adjusted based on a calibration routine performed by the user, the calibration routine including having the user perform one or more actions multiple times.
