Project OverviewProject Overview

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