Abstract

This helmet mounted display (HMD) was designed for the extravehicular mobility unit (EMIJ) to be used on the Space Station Freedom. The HMD will be able to display text, graphics, and video to the astronaut. The image will be above his/her normal field of view (FOV) at a comfortable distance. It is believed that this device would be extraordinarily useful in performing scheduled and emergency extravehicular activities (EVAs) . This HMD may be voiceactivated for true "hands-free" operation, without invading the prime work envelope. The Technology Innovation Group (TIG)/Lockheed Engineering and Sciences Company (LESC) holographic HMD was developed for the Crew and Thermal Systems Division and NASA-Johnson Space Center. This HMD is unique because it uses holographic optical elements (HOEs) on the pressure helmet and protective visor surfaces to relay an image from a CRT directly to the eyebox. This HMD provides the user with a biocular virtual image in a 25 degree diagonal FOV, maximum combiner transparency, minimal volume dimension, and an unencumbered working field of view.
