Virtual Imaging Peripheral for Enhanced Reality Aaron Garrett, Ryan Hannah, Justin Huffaker, Brendon McCool

Abstract Our project, code named Virtual Imaging Peripheral for Enhanced Reality or VIPER, is an augmented/virtual reality system. It will track a user’s head location and perspective and use this information to find the location of a camera position in a virtual environment. With a pair of video glasses the user would then see the virtual environment at the cameras location. As the user moves around a table top sized environment their actual and virtual perspective changes, allowing them different viewing angles of the virtual space.

Project-Specific Success Criteria 1. The ability to communicate time stamp data using RF between the base unit and head unit. 2. The ability to display images to the video glasses. 3. The ability to calculate estimate of angle and position of head unit using accelerometer, gyroscope, and compass. 4. An ability to find angle displacement of head relative to IR beacon origin using glasses mounted camera. 5. An ability to find distance from base to head unit using ultrasonic emitter and receiver.
