@Maurice Avery -- an interesting idea (using the WiiMote as a camera to track IR Drumsticks), however it might not work particularly well. A thing about IRED's (and LEDs in general) is they don't have even light diffusion (many IRED's have 45 degree viewing angle before the power is halved, there's a rating on the packaging usually). So a drumstick with IR LED's would be nearly invisible on an upstroke, or any time the IRED wasn't pointed in the general direction of the WiiMote (it could be detected weakly, depending on how sensitive the IR CCD in the WiiMote is). Going off your idea, however (if the Wiimote is sensitive enough), it would be possibly with two wiimotes to almost entirely map out where the IRED's were in 3-d space (with depth perception, basically) so you could have it so that seperate drums were spaced accordingly. There's all sorts of possibilities really, but I suspect that interfacing to the Video circuitry would have a noticeably larger lag to it (lots more data to handle). I like this, and look forward to the two-mote version.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
