ABSTRACT:
The present invention concerns a device for detecting and representing movements. The device includes a position sensor for detecting the current position of a reference point of the device, a data processor for processing the position data detected by the position sensor and a projector for projecting on a surface an image projection of the detected and processed position data. The data processor takes into account a modification in the current position of the reference point such that the projection image on the surface remains substantially stable concerning location and position.
