12. DPU Design Angstrom OS installed on Beagle Board (DPU)
C++ compiler installed
Interfaces with Texas Instruments DLP Pico Projector
Capable of running OpenGL ES (embedded systems)

13. Virtual World Design OpenGL virtual world
Buildings labeled with appropriate names
Movements in real world paralleled in virtual world

14. BAE System HUD Display FOV: 20ºx20º Resolution: 800x600 pixels
Input: DVI-D

15. Team Wolf 2009 HUD Design

16. Calibration Feature
Each user has unique facial configuration and unique viewing mode through glasses
Gyroscope does not provide absolute data and might need to be recalibrated
Future data will be displayed relative to calibration data, increasing accuracy for various user types
Two push-buttons connected to DPU that will increment or decrement pitch/yaw/roll offsets

17. Calibration Implementation

18. Work in Progress
Improving positioning and field of view accuracy in virtual world to better represent real world situation
Combining compass and gyroscope data to improve directional accuracy of system
BAE agreed to lend military grade HUD
Building alternative display using Texas Instruments DLP Pico Projector
