By facilitating
the placement of properly registered 3D models into a real-time
video feed, the Augmented Reality Gaming Table
opens up new possibilities for tangible, physical interfaces
to mixed reality games.
Technology:
The Augmented Reality Gaming Table is based on software called
ARToolKit,
which was developed at the University of Washington by Mark
Billinghurst and his team.
Rig:
Our rig is composed of off-the-shelf parts, including a webcam,
a projector (though any display would suffice), and a high-end
comsumer-level computer. The camera is placed at a three-quarters
angle to the playing surface so that the video feed contains
the maximum ammount of dimensionality. The feed from the camera
is processed by ARToolKit, along with our own custom game
code, and projected on the display surface with the additional
virtual elements included. Our rig includes 5.1 surround speakers
for 3D audio capability.
We prototyped
two games, the Augmented Wizard Duel and Cannon Fodder, and
designed two other games, AR Pong and Spheres of Influence
(created by Jesse Schell). Click on the titles below to learn
more about each design.
