  2. 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.

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