Hmm? They use EXACTLY the same method

 

Move - uses a camera (PSeye) to measure the apparent size of an object with known absolute size (the ball)

Wiimote - Uses a camera (the end of the Wiimote) to measure the apparent size of an object with known absolute size (the sensor bar)

 

It's confusing because Nintendo refer to an emittor as a sensor, but now you know - and knowing is half the battle.

 

And no, Wiimote without WM+ is more accurate than to the cm. Ever actually used one?

What are you trying to spin there? An infrared signal sensor and a camera is not the same thing. The Wii bar consist of infrared emitter position at each extremity. On the end of the Wii mote you have a light sensor that detect those infrared signal. Then the console use triangulation to know your position (1). Because of this triangulation process, moving fast with a Wii mote, will leave the device running on his accelerometers by themselves (not precise) (2). Also, the Wiimote needs to be pointed towards the screen (3). When its not pointed towards the screen, it doesnt sense the infrared signal, it becomes dependant of the accelerometers to estimate whats doing on (not precise). Best example of this would be the bowling game, half of your swing cannot use triangulation. Many things that will never happen with PSmove due to the differences in the technology behind it. Im pretty sure there is other differences also. Anyone knows about other factual differences?

 

(1)"The light emitted from each end of the Sensor Bar is focused onto the image sensor which sees the light as two bright dots separated by a distance "mi" on the image sensor. The second distance "m" between the two clusters of light emitters in the Sensor Bar is a fixed distance. From these two distances m and mi, the Wii CPU calculates the distance between the Wii Remote and the Sensor Bar using triangulation.^[42]"

(2)"The Sensor Bar is required when the Wii Remote is controlling up-down, left-right motion of a cursor or reticle on the TV screen to point to menu options or objects such as enemies in first-person shooters. Because the Sensor Bar also allows the Wii Remote to calculate the distance between the Wii Remote and the Sensor Bar,^[44] the Wii Remote can also control slow forward-backward motion of an object in a 3-dimensional game.^[45] Rapid forward-backward motion, such as punching in a boxing game, is controlled by the acceleration sensors. Using these acceleration sensors (acting as tilt sensors), the Wii Remote can also control rotation of a cursor or other objects.^[46]

(3)"It is not necessary to point directly at the Sensor Bar, but pointing significantly away from the bar will disrupt position-sensing ability due to the limited viewing angle of the Wii Remote."

 

I spin nothing but knowledge of the infinite majesty that is physics - infared and light are both electromagnetic fields oscillating at right angles to each other. An infared sensor is just a camera sensitive to a different frequency.

 

The Wiimote uses an electromagnetic wave detector to determine the apparent size of an object based on its electromagnetic emissions, and uses this and knowledge of the actual size of the object to determine distance

Move uses an electromagnetic wave detector to determine the apparent size of an object based on its electromagnetic emissions, and uses this and knowledge of the actual size of the object to determine distance

 

As it says in what you posted "the Sensor Bar also allows the Wii Remote to calculate the distance between the Wii Remote and the Sensor Bar,"

 

Look, I'm not trying to troll or anything, it is exactly the same method, trust me.

 

The fact both technic uses light to evaluate the position of an object doesnt mean they do it the same way nor that they sense the same type of light either. They are both very different tech even if we want the same result. It doesnt seem like you read my post at all. I didnt insinuate you were trolling, but if you feel you need to justify yourself...

Heh both techs are different, but thats mostly because the PS Eye was never meant to just sense IR light.  But while we're bringing up the pros and cons, yes the Wii remote needs to be pointed at the screen from time to time, most games automatically recenter it when you start pointing it at the TV, since there are very few IR lights in a house it usually doesn't become a problem unless too much sunlight is coming in.

Move is reversing things putting the camera on the TV end, one issue is the way it senses from what I've read is the color of the lightball, it detects colors in its view and changes the light on the ball to be a color that isn't in the room, which would be fine but color is much more prevalent than IR light, my room is personally like a rainbow cause I've got colorful crap everywhere.  Other issue being the light ball is only one point of reference, much like their face tracking, it bases it all off size in the 2D image to judge if the object is getting closer or backing away, if you've used this tech or seen it used, its not the most accurate, it is however helped out with the use of the gyros in the move controller.

Honestly there are advantages and disadvantages to both systems, making the types of games you can make for it very different, like I REALLY don't want to play a lightgun/TPS/FPS game on the Move since the movement to point at various points of the screen is more than just a flick of the wrist, I will probably play Socom just because but I don't see it stacking up to the CoD4 Wii controls.  On the other hand it is very likely sword fighting games will be much better on Move, I've already seen what Wii can do with WSR, which is very good (but has yet to be really untilized in a full game) but the sword fighting game on Move looks like it can do that plus not have the issue where you don't point the Wii remote at the screen after so long it becomes a little off, so that'll be nice.
