Abstract
An interactive system may include (1) a facial coupling subsystem configured to conduct a biopotential 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 a compliant 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 a characteristic of the biopotential signal and (b) use the characteristic of the biopotential signal to determine a gaze direction of an eye of the user and/or a facial gesture of the user. In some examples, the facial coupling subsystem may include a plurality of compliant electrodes that each are configured to comply in a direction normal to a surface of the user's face. Various other apparatus, systems, and methods are also disclosed.
