3rd Party WiiMote with location capable gyroscopes
My love for the WiiMote goes way beyond Raymans Raving Rabbits and other fun games as I embrace the gyroscope filled controller for next generation interfaces and 3d tracking in various forms. 3d tracking with the WiiMote has but one big problem. While it is quite great to get the bank and roll data out of the white brick it is only possible to know where it is using infrared lights. Infrared lights tend to behave like real lights as they can get obscured or not in the right place when you need them. Sure you can try to get the location of the WiiMote by using the accelerometers and gyroscopes but the result - and I have tried that - is quite bad. You get what people call a drift very very badly especially when you move around the room with the thing and attach a camera to it.
Now the Boston USA based company Motus Corporation claim to have developed a WiiMote of their own that can be used without the infrared sensor bar and still get the location right. They developed it in the form of a Samurai sword handle and made it primary for the target group of golfers (their are known for golf training gear) but if any of their claims hold true this is the revolution of the sensor revolution. The gyro package send new data every 30 Milliseconds is called Darwin (probably because the software to read out WiiMote data on the computer is Darwin Remote?) seems semi compatible with the WiiMote (the protocol is the same but there is different data available). The firmware has error correction build in and my uneducated guess is that they slapped another 5 or so accelerometers in there to get a more accurate average reading. Surprisingly the price is "in the range" of not beeing overly gold encrusted (its going to be somewhere between $79 and $99) and if the claims hold up its a bargain because then you can build a real realtime camera tracking solution and with a couple of these also a motion capturing solution that rivals about everything out there in the price range 10k+. Lets hope they find a distributor soon (or figure out that in these days you can self distribute this and still be successful)
