On a Wired post criticizing the initial round of PlayStation Move games, commenter memebag pointed out a distinct difference between Move and Wii, which seemingly plays into the latter’s favor.
“Instead of a camera on the TV looking for lights on the remotes, each Wiimote has a camera that looks for the light bar on the TV,” he explains. “Itâ€™s a smarter solution, since the Wii can tell where the Wiimote is pointed, not just where it is in the room.”
There. Now you can feel better about the four year-old motion technology you already own.
