Project: AR Maze
Concept
The idea of this AR game lies in our all childhood: I guess many children had a version of this wooden labyrinth with some holes, where you had to steer a steel marble through the level without dropping the ball into a pit. To move to marble you had two buttons to turn which would affect the whole maze to get tilted a little bit.
The yet easy concept of this is game is perfect to test a 100% direct input device for this augmented reality application: you hold a (quite big) marker in your hands and by tilting this pattern you get the same effect you had with the buttons. But now the effect will be triggered on the virtual labyrinth appearing on your hands. It turns out to be the most intuitive input device.
These days Nintendo Wii and others adopt this idea, of course, but so far it was not seen this way in a mixed reality context.
