A -- DEVELOPMENT OF A RESEARCH HEAD-MOUNTED DISPLAY VIRTUAL REALITY SYSTEM SOL N00203-00-Q-3042 DUE 012100 POC Wanda Lee (850) 505-6017 (ph) (850) 505-6340 (fax) Development of a Research Head-Mounted Display Virtual Reality System General Description: a head-mounted display virtual reality (HMD-VR) system will be developed, consisting of digitized satellite imagery of the Northern Italy (Dolomite Mountain) area. The area size will be approximately 75 x 75 Nautical Miles, centered around the Aviano Airbase. Exact latitudes and longitudes will be provided in the final specifications. System willbe programmed using an F-18 aircraft model. Included with the cost of this system will be user access to the programming source code, and all CPU hardware, with the exception of HMD, eye-tracking, and head tracking hardware. VR data base characteristics: Pixel resolutions: no less than 480x640 (with color) for HMD applications and at least 800x600 (with color)for fixed monitor display. Display fidelity and resolution must be equal to or greater than the HMD-VR system now in use at NAMRL'S HMD lab (20 meters per pixel). Must be compatible with Protec-high resolution HMDsystem. 3D rending of at least 20 geographical/man made areas. To include: 1. Two airfields with buildings, 2. One cable suspended similar to what might be found with a mountain cable car system (exact co-ordinates to be provided by NAMRL), 3. Five bridges, 4. Five threat sites, RADAR sites with missiles, 5. Five power line sets, for navigation, 6. Two power plants. Cloud and Fog options, with capability of selecting either sudden or gradual IMC conditions. Formation flight option, with capability to select either a preprogrammed lead aircraft, or an actively linked aircraft being flown on a "mirror" system. Head down display option: must run on a separate screen, similar to NAMRL's current VR mission preview system. Head UP Display (HUD): modificable HUD must have the following selectable modes. Mode A: HUD slaved to forward aircraft position (requires head tracker input for HMD positioning). Mode B: HUD fixed to head position (i.e., HUD position remains fixed on HMD screen). Mode C: with monitor use the HUD remains centered. Mode D: HUD toggled off with either HMD or monitor use. Follow-me-lines: system must have user changeable following me navigation lines similar to what is now in use with NAMRL's mission preview system. Lines toggle selectable to on or off mode. Interface charateristics: the proposed HMD-VR system must have the following interface capabilities: Polhemus Fastrack head tracker system (head tracking must have two modes: (1) head tracker driven VR screen presentation for HMD use, and (2) with fixed monitor use, head tracker info recorded, but not used for driving screen presentation. Biolog two channel system, Iscan eye tracking system, Thrustmaster stick and throttle control (with ability to trim aircraft and fire missiles from stick switches). Data Storage File: must be capable of storing the following variables at selectable rates of 2,5,10,or 20Hz. Time, Polhemus Fastrack Head position data in degree (yaw, roll, pitch), aircraft attitude id degree (yaw, roll, pitch), Aircraft altitudein feet (both AGL & MSL), Aircraft speed in knots, Aircraft position information in lat & long, Aircraft heading information in degrees, Cloud on, off, or incremental positioning, Stick inputs, Throttle inputs, ISCAN data, Biolog data, Missile firing data (i.e., when is a missile fired), Lead aircraft relative position information in feet (relative distance and elevation for own ship position), follow-me-lines, on or off, Event marker, reads digit toggle input on through nine.
