  • Patent number: 5323174
    Abstract: A device used for measuring the orientation of a human head about one or two axes and converting that information into an electrical signal in the analog or digital domain includes a headset and includes one or two electromechanical orientation sensors which provide an electrical signal that corresponds to the orientation of the head without any reference to an off-of-the body reference. The orientation sensor includes a signal generating device, such as a variable resistor, coupled to the torso of the user via a mechanical linkage. As the head moves, the linkage moves and changes the resistance of the variable resistor. The change in resistance corresponds to the orientation of the head. One orientation sensor is used to measure the horizontal, or lateral angle, of the head with respect to the torso, or shoulder blades. Two orientation sensors mounted on each side of the head measure both the lateral and vertical angles of the head with respect to the torso, or shoulder blades.
