Abstract
Abstract A headset for supporting electrical contact means which are operated by the movement of the jaw and/or the eyebrows is electrically connected to a computer, video game console or the like to provide educational and recreational opportunities to persons who can move only the jaw and eyebrows. A flexible chin strap formed with a chin cup supports a horizontally mounted chin bar having an electrode contact on one end. A housing having a plurality of sides, each inner face of which has mounted thereon an electrode connected to a computer interface is mounted around the chin bar electrode to provide a means for the user to establish contact between the chin bar electrode and one or more of the housing electrodes by up, down or sideward movement of the jaw. An adjustable head band formed to fit above the eyebrows of the user is formed with a contact electrode extending outwardly from the center portion of the headband between the eyes. A C-shaped housing having electrodes attached to the upper and lower arms, which electrodes are operationally connected to a computer interface, is mounted around the headband electrode to provide three switching possibilities, i.e., no contact when the eyebrows are relaxed, contact with the upper electrode when the eyebrows are raised and contact with the lower electrode when the eyebrows are lowered, as in a frowning motion. A straight track potentiometer with an outwardly extending control stick is mounted in contact with the second end of the chin bar to permit the operation of the potentiometer by the upward and downward motion of the user's jaw.
