How could we pinch the whiteboard with two LED to simulate a mouse scroll? I'm thinking of pinching a Google Maps to zoom in and out; as Google Maps already reacts to the mousewheel it should be easy to implement. I'm also thinking of pinching a picture to zoom in and out, like Microsoft Surface or the iPhone. I'm also thinking of pinching a web page to zoom in and out; as browsers like Internet Explorer and Firefox already react to CTRL+mousewheel it should also be easy to implement.

(For completeness, I also posted this feature request on Uwe Schmidt's Wiimote Whiteboard project at

If you take a look at the fingertracking it can be used in a similar fashion.

I agree that multi-touch interaction with the operating system would be pretty cool. However, I don't think this functionality should be added to my software. I suggest instead to write another program that uses the already available TUIO messages from my software.

Laurence Muller has also released an application called tDesk that brings multi-touch interaction to Windows XP.
