Abstract
A head mounted display system includes a frame that can be worn on a user's head wherein the frame supports a display and an optical system that projects an enlarged image of video information depicted on the display at a distance from the user. Also mounted on the frame so as to form an integral part of the head mounted display system is a barcode sensor for detecting one or more barcodes in the field of view thereof. A processor of the head mounted display system decodes barcodes detected by the sensor and determines the location of detected barcodes within the sensor's field of view. The processor utilizes the decoded barcode values and locations to control the video information depicted on the display for head tracking purposes or the like. The head mounted display system of the present invention has applications in both augmented field of view and virtual reality applications.
