Chojacki said that the Fraunhofer motion tracker could be replaced by a Microsoft Kinect sensor, but that theirs is specially tailored for the project.

Fraunhofer has been working on its motion tracker well before the Kinect premiered, and has shown it at previous IFA shows.

In 2008 it was used in the iPointPresenter project, which allowed users to control a mouse cursor using gestures. At the time it could only track objects on a 2D plane.

In 2009 the team upgraded the system for on the X, Y and Z axes. Chojacki was also involved with iPoint3D.
