Holy shit, that is amazing. How did this not hit the front page?Very Cool!i immediately started to think about how to implement this into my home, and i thought about using an EEE PC, but unfortunately they don’t have bluetooth to handle the wiimote …See also the finger touch hack.coolinsane wiimote hackWTF. This is phat.Freaking awesome!Using a wiimote as a SMART BoardWow, I didn’t expect such precision from the remote’s CCD!Ah, I didn’t know about the blob detection. That makes it much more suited, then. Anyone know how it detects when you touch the pen to the surface so it knows when to click?I think he has to press the button to turn the light on when he touches the surface. The mapping from blob position in the sensor to position on screen is a strictly 2d transformation that assumes the LED is in the plane of the touch surface.Well, I got home from work and built one of those IR pens. It works but the IR LED I used (the only one they had at Radio Shack) does not have a very wide spread. It only gets recognized by the remote within about a 15 degree angle, which means the LED has to be pretty much pointed at the remote the whole time.Would be a cool idea for projector manufacturers to include.Like the comment above said - No, a webcam would not be anywhere near as good. The wiimote does blob detection and returns blob positions to your OS rather than image data that you have to process yourself.
