Abstract: A system for determining a direction of gaze of a user, comprising a set of electrodes arranged on earpieces, each electrode comprising a patch of compressible and electrically conducting foam material. The system further includes circuitry connected to the electrodes and configured to receive a set of voltage signals from a set of electrodes arranged on an audio endpoint worn by a user, multiplex said voltage signals into an input signal, remove a predicted central voltage from said input signal, to provide a detrended signal, and determine said gaze direction based on said detrended signal. Such conducting foam materials provide satisfactory bio-sensing performance for a wide range of compression levels and over time. In the case of on-ear headphones, the foam electrodes may be integrated in the cuffs with little or no effect on the comfort level.

Abstract: A system for determining muscle activation comprises a set of electrode adherable to a skin of a subject, and a processor in communication with the electrodes. The processor has a circuit configured for receiving locations of the electrodes and electrical signals detected by the electrodes, analyzing the signals to identify a section of an active muscle, identifying locations of at least a segment of active muscles and activation patterns of the active muscles based on the identified section, and constructing a displayable map of the locations and the activation patterns, wherein patterns corresponding to different active muscles are distinguishable on the map.
