13 Electrical and Computer Engineering  OpenGL virtual world Buildings labeled with appropriate names  Movements in real world paralleled in virtual world Virtual World Design

14 Electrical and Computer Engineering BAE System HUD  Display FOV:20ºx20º  Resolution:800x600 pixels  Input:DVI-D

15 Electrical and Computer Engineering Team Wolf 2009 HUD Design

16 Electrical and Computer Engineering 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 Electrical and Computer Engineering Calibration Implementation

18 Electrical and Computer Engineering 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
