This evening I’ve combined my movable window demo with the multitouch experiment from the other day and this resulted in my first attempt at creating a multitouch application which will allow you to drag around multiple boxes at the same time. I’ve also replaced my logitech webcam with the Philips SPC900 and the performance has increased dramatically.


In the screenshot above - taken directly from flash - you see the dots as rendered in touchlib/TUIO debug mode, which represent my fingers, dragging two windows at the same time.

I also have invested in an NECVT47 projector (rather cheap at 160 pounds from ebay), so I can start projecting real images and change from a multitouch pad, to a multitouch screen. However, it seems a little less straightforward than I assumed initially. Obviously the light from the projector will interfere with capturing the finger presses on the table, which means I’ll probably need to look at an infra-red (FTIR) solution instead, complicating things slightly.

So the story continues…
