Project Outline Orientation Sensing Unit Gather information from orientation sensors Data Processing Unit Process data from the sensors, compute relative location of POIs, render perspective, send video feed to HUD Head-Up Display Label surrounding area

Specifications Able to label building +/- 3º off center from a min distance of 150m Be able to measure pitch and roll accurately within +/-2º. OSU must be head mountable. Batteries must be able to power OSU for 4 hours continuous use. System must have means of calibration/reset.

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

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

Team Wolf 2009 HUD Design

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

Calibration Implementation

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
