Head-Mounted Display System

Individual full pages of a data set containing many pages are individually accessed and displayed in the field of view of an operator wearing a head- mounted display to which the selected pages are transmitted, solely by head movement of the operator.

The head mounted display incorporates a directional infrared transmitter which sends out a coded command signal identifying the head-mounted display and indicating its state of readiness to receive data to be displayed. A number of wide-band infrared receivers, distributed in spaced-apart relationship over a predetermined work area viewed by the operator, individually respond to receipt of the command signal when line-of-sight communication is established between particular receivers and the directional transmitter on the head-mounted display, to cause the data content of the page of data associated with that transmitter to be broadcast by a wide-angle transmitter common to all the receivers. The broadcast data is received by a wide-angle receiver also incorporated in the head-mounted display, where it is decoded and displayed as an image superimposed on the field of view of the operator. The arrangement is such that, as the operator turns his head, one receiver after another is accessed bringing one page after another into the operator's field of vision. The spacing of the stations is such that the successive pages of the data set are presented to the operator in order, in much the same...
