3d navigation and facedetection

Inspired by Johnny Chung Lee’s wii-headtracking experiments we decided to do everything a little bit more “elegant”. In our setup the user doesn’t have to wear IR-leds to be detected. Technically the installation has a built in facedetection, so it’s possible to track in realtime all users in front of the setup quite accurate. According to distance and positions the virtual 3d space is adjusted. Always the closest user “wins” the focus.

If you like this kind of navigation it’s worth to checkout “Buddha in a Box” by Finn Rudolph which is based on a similar approach.

3d model interaction and markertracking

A simple example for a 3d markertracking done with ARtoolkit. User can interact with three different markers: one represents the node structure, the other two enable the user to manipulate (attract and distract) the node structure.

3d navigation and potentiometer + distance sensor

User can navigate a simple 3d structure with a potentiometer and IR-distance sensor. Potentiometer is an usual in trade powermate, IR-distance sensor is controlled by an arduino board.

3d navigation and wii controller

User can rotate and zoom the same 3d structure like above. The two IR-leds acting as pointing device, the position of the two pointers is detected with by a standard wii-controller.
