Another Kinect Hack has been created. This time it's called the Keyboard Anywhere and basically allows a keyboard to be virtually created on any surface.
The system uses the OpenKinect library as well as Python code and with all that, it can create a virtual piano on a desk, floor, wall or any other surface.
To get it to work you first need to create a space and point the Kinect at that space. Once done, you define the area where the piano is, move a virtual piano on to that space and once done, you get a virtual piano. When used on a floor, it can stretch the width of a room.
The video below shows the Kinect hack in action...
