The Augurscope is a portable mixed reality interface for outdoors. A tripod-mounted display is wheeled to different locations and rotated and tilted to view a virtual environment that is aligned with the physical background. Video from an onboard camera is embedded into this virtual environment. Our design encompasses physical form, interaction and the combination of a GPS receiver, electronic compass, accelerometer and rotary encoder for tracking.
