The Augurscope 2 is a portable mixed reality interface for outdoors, consisting of a base unit and a detachable top. Users can move, rotate and tilt the display in order to view a virtual environment as it would appear from that particular vantage point.
The Augurscope 2 has a base unit and a detachable top. The base unit, featuring three wheels, is designed so it can easily be moved around physical terrain. It contains most of the computing, communications and power supply. In particular, the base contains the computing power to render 3D graphics that are then communicated wirelessly as composite video to the top unit. The top unit is mounted in a gimble on the stand. The gimble allows indefinite horizontal as well as vertical rotation.
By removing two pins, the top can be taken off for handheld use. We made use of a sunlight readable display to cope better with bright conditions. This has made additional physical shading unnecessary. The detachable top also contains the necessary tracking technology (such as a GPS receiver and digital compass) for global position and orientation (this information is communicated wirelessly to the base). Whether attached to the base unit or used handheld, the movement and rotation of the top changes the user’s viewpoint within the virtual world.
