Wii Controller for Virtual Reality
Uploaded by: spelunkerucd
Video Description:
Movie showing how to hack a Wii controller to track its absolute position and orientation in space using a custom-made IR beacon.
Shows several examples of 3D graphics applications used with a Wii controller, and a virtual light saber.

The lag in this video is due to my poor low-pass filtering; I introduce lag to reduce jitter. Games that are to a large degree based on accelerometer pattern matching get lag because the pattern logic has to uniquely identify the beginning of a stored pattern before it can apply the pattern's action to the game. So depending on how complex the patterns are, you get more or less lag.
I guess that doesn't answer your question, though...
looks at it blankly.
yea i better stay in school
Why can't Nintendo, or ANY 3rd-party-developer, use the Wii remote as it was intended?!
why would a company such as ea go out of their way to develop something ground breaking that uses something similar to this video in a wii game for their big name franchaises when a vast majority of the current audience is content with whats currently there
if only there were more publishers dedicating time, effort and resources into the wii like high voltage the people behind conduit
Developers could make games that do this! Now! No Wii Motion Plus needed!!
The beacon/software I'm showing here can tell exactly where the Wiimote is in relation to the beacon.
Look at the lightsaber section, where the blade (drawn on the computer screen) more or less exactly follows the real Wiimote I'm holding in front of it. MotionPlus can't do that -- whether that's important for games is another question, though. :)
it would be interesting if you could track a larger area bu making different shapes with LEDs that the application could detect. that would be a great step to try, i dont know how well it would work though.
And spelunkerucd, there is no reason why a full 6-DOF IMU, as the Wiimote will be with the Wiimotion Plus, can't do three-axis dead-reckoning spacial tracking. And it will be referenceless so, assuming bias compensation and proper calibration, no more sensor bar.
