69 -- DATAVISOR HEAD MOUNTED DISPLAY SYSTEM SOL 9BE3303521P DUE 042895 POC STEVE JANNEY, Tel:713-483-8505 Contracting Officer:LISA REA, Tel:713-483-8395 This is a sources sought synopsis sent out for a Virtual Reality Datavisor Head Mounted Display System. The head mounted display system will be used as the stereo graphic display device in the Integrated Extra Vehicular Activity (EVA)/Remote Manipulator System (RMS) Virtual Reality Training System to increase the training efficiency of the simulation for EVA astronaut crewmembers to prepare for critical EVA's on upcomming space shuttle missions. --The head mounted display system must meet the following specifications: 1. Must be compatible with the Silicon Graphics Inc. Onyx Reality Engine computer graphics systems. 2. Support video formats up to and including 1280 X 1024 (pixel resolution) at 30 Hz. 3. Have usable field-of-view of at least 100 deg. Horizontal x 65 deg. Vertical in conjunction with at least 30 deg. of stereo overlap. 4. Exit pupil greater than 12 mm. 5. Brightness greater than 10 foot-Lamberts at the eye. 6. Control of video control electronics (display parameters and diagnostic functions) through a standard RS-232 computer interface. 7. Weigh less than 4.5 pounds. 8. Have mounting points for standard position sensors,headphones, and microphones. 9. Be delivered prior to September 1, 1995. 10. The entire viewing area (field of view) must be free from any extraneous external or internal (to the optics) reflections. The final acceptability of the display will be based entirely upon demonstration to, and acceptace by a panel consisting of at least six (6) astronauts with extravehicular activity (EVA) training experience in the Virtual Reality Simulation. --The head mounted display system will be delivered to the Lyndon B. Johnson Space Center in Houston Texas. (0089)
