Abstract: A headset for operably disposing speakers and a visual display on the head of a wearer. The headset includes a beam extending over the vertex of the head for contacting the brow at one end and cooperating with a nape strap on the posterior end for adjusting the fit. Rigid arms extend from the posterior end adjacent the head to terminate in the vicinity of the ears. The arms include compressible compensators to substantially accommodate any size head therein. A visor is pivotally connected to the support beam adjacent the brow piece. The attachment of the visor to the support beam permits the visor to be disposed in a donning position away from the face or an operable position adjacent the face, without requiring a weight bearing surface on the face.

Abstract: A low cost head tracker for a virtual reality head set for determining the orientation of the head set relative to the earth's magnetic field includes a magnetic sensor responsive to the earth's magnetic field, and disposed on the head set and arranged with respect to a vertical axis of rotation of the head set to produce a displacement signal relative to the angular displacement of the head set with respect to a calibration orientation relative to the earth's magnetic field, and a signal processor connected to the magnetic sensor, and responsive to the electrical displacement signal for producing an output signal proportional to the orientation of the head set relative to the calibration orientation.
