You're completely ... ( 5 months ago by fashnek)
You're completely mistaken. The Wiimote, which is an IR-sensitive camera that tracks 0-4 light sources, is a FAR stretch from what's going on here. This uses multiple sensitive sensors and rapid patterns to locate points. The projector provides a stimulus for location AND display, whereas with a Wiimote method, a display would be completely separate from the [Wiimote] camera and the [IR] light source(s).
As I was saying, ... ( 5 months ago by fashnek)
As I was saying, this method can be a LOT more precise, since different locating patterns can be used for each vertex, and precision is mostly based on projector resolution, which can be very high. You get to move sensors around, each being able to be precisely and independently located. With a Wiimote, on the other hand, you're stuck moving light sources, which (a) must be the (1-4) brightest IR sources in view; and (b) cannot be independently tracked without major assumptions by the software.
