Patent attributes
An interactive system (e.g., a head-mounted-display device) may include (1) a facial coupling subsystem having electrodes configured to conduct at least one biopotential signal (e.g., an EOG or EMG signal) generated by a user's body, (2) a receiving subsystem electrically connected to the facial coupling subsystem and configured to receive, from the user's body via at least one electrode of the facial coupling subsystem, the biopotential signal, and (3) a detection subsystem electrically connected to the receiving subsystem and configured to (a) determine at least one characteristic of the biopotential signal and (b) use the at least one characteristic of the biopotential signal to determine a gaze direction of an eye of the user and/or a facial gesture of the user. Various other apparatus, systems, and methods are also disclosed.
