Cohort Studios: Move is “so much more accurate” than Wiimote

The Wiimote's ability to detect depth is based on distance between detected light sources, and it is far less accurate than analyzing a camera image with a clear marker of known size (like a glowing sphere) would be.

Otherwise, I agree, the Wiimote+WMP should be nearly the same as the Move. Spatially, however, the Move's accuracy margins would be measured in millimeters, whereas the Wiimote's accuracy margins would be in terms of centimeters.

The Move's ability to detect depth is based on a fixed camera getting the size of a moving light source.  The Wiimote's ability to detect depth is based on a moving camera getting the distance and angle relating to TEN fixed light sources (possibly even using the TV too). The size of these light sources are also taken into consideration. Just go back a few posts in this thread where I posted the sensor bar pic, look at the cluster of 5 LEDs (same setup at the other end of the bar) and have a look at the second patent link. It demonstrates that to detect a difference in size between 3-5 LEDs in a row would require an adequate level of precision, which the Wiimote appears to have had from the beginning.
