While many HMD designs exhibit see-through capability and a relatively narrow field of view (FOV), the HMD design presented int his paper is purposely immersive since it seeks operational roles requiring anthropomorphic telepresence, which seeks to procure its operator the impression of being at a remote location. This technology is applicable in situations where it is deemed too expensive and/or hazardous to send an operator on site. The HMD developed for this purpose exhibits SVGA resolution, and achieves a FOV of approximately 84 degrees through compact 6-element eyepieces. It is color and stereo capable, and the usual degradation in effective resolution due to RGB triads from conventional composite color display devices is circumvented by the use of a sequential color technique, which yields a very acceptable image quality with acceptable pixelation, in spite of the high FOV. Several add-ons to this HMD, greatly enhancing its capabilities, have also been developed and will be described briefly; they include translucentgraphical overlays, an embryo of real-time video CODEC technology that could enable fully digitized visual telepresence at acceptable bandwidths, the associated robotics complementing the HMD and enabling actual telemanipulations, and finally, a time delay (in static environments) and motion compensation algorithm.
