3. Project Overview Our project, code named Virtual Imaging Peripheral for Enhanced Reality or VIPER, is an augmented/virtual reality system. It will track a handheld unit’s location and perspective and use this information to find the location of a camera position in a virtual environment. Through a LCD screen on the handheld unit the user will see the virtual environment at the cameras location as if the handheld unit was a window into the virtual world. As the user moves the handheld unit around a table top sized environment the handheld unit’s actual and virtual perspective changes, allowing for different viewing angles of the virtual space.
