The PrimeSense sensor, better known for its Microsoft implementation named Kinect (for XBox360) has raised a huge interest in among Computer Vision scientists.

This sensor has been primarily devised for hand gesture recognition (e.g. wave, swipe, push, circle, etc.), or the body pose; the very low price (approx. 150€) and the very reliable body/hand analysis have triggered a real success of the product.

Beyond body/hand analysis, the potential applications are many and are basically limited only by creativity. I have personally developed an application product that, through the use of the PrimeSense sensor provides a virtual “touch” sensitivity (similar to a touch screen) to any surface, such as a window shop, a back-projector screen, a painted wall, or even the surface of a liquid; obviously this can be used to make “touch sensitive” even a regular 42″ LCD/LED.
