I just watched the wiimote finger tracking vid and the whiteboard vid. I was thinking, what if you could combine the two together. you have some gloves with IR led's on the back of you fingers and on the front are switches. When you press down on one of the switches, a consecutive IR led will light up, No. if you had a projection/screen on a table, you could just press down on the finger and it will act as if you are actually pressing into the screen. Id you don't understand me, just tell me and i'll try to be more clear.

no, pressure sensitivity can be for later, but right now, you just have a glove with any type of switch, you could even make your own one if you reall wanted to, and an led on the finger. THen you just use the wii whiteboard basicall but instead of pressing the button on the pen, your pressin a button on your finger

using the Wii remote instead of a webcam with a disabled IR filter would probably be more powerfull because of it's higher resolution and hardware identification of IR blobs.
I am concerned about the 4 point limitation though. Just wondering if the multitouch library used in the DIY projects (there are lots out there) might overcome this issue instead of the Wiimote tracking driver used now.

I made this one night just to show my wife how cool the technology was. But yeah, light on the back, switch on the front.  Works perfectly. Ignore the picture I drew, the "Fiinger" actually draws really well and is surprisingly accurate.  I'm working on a "glove" right now (with multiple finger lights/switches).  I'm just waiting for some Mac-compatible multi-touch programs to pop up now.
