The Move is something a little more the Wiimote. Its read through the camera and fully controls 3D space. The Wii mote was the answer to helping Sony realize how to properly control the third dimension.

before the WiiMote was even in development we are talking about a time line of over a year here, the Move software was already being developed for spatial volume of depth of coordinate mapping. The use of a sphere is not a shocker, and the Wii even with the Motion + adapter is still missing one key element to offset sensor drift , which the Move does indeed contain. The fact that Sony already demonstrated tracking a sphere with the eyetoy in a 3d volume of space and did it well, showed that indeed they were well aware of the direction that they needed to go. Like i said the WiiMote turned side way's and the Move turned side way's shows the direction on how each company viewed Motion control's. On one token even though the Move was more accurate than WiiMotes even with + the Wii Mote could serve as a mini game pad to control games with, something the Move was not designed to do.

The sensor bar provides information for M+ to correct drift. It contains ten infra-red LEDs in two rows of five, with the outer two LEDs in each row pointing outward. The apparent size, distance between, and viewing angle of these LEDs, allows the wiimote camera to capture information about relative position, roll and yaw. Move NEEDS a magnetometer, because a camera cannot possibly report the rotation of an unmarked spherical light source - only its X/Y position in the frame, and Z-axis changes perceived via the apparent size of the glowing ball, much like the sensor bar LEDs (yes, Wiimote can handle the Z-axis).
Don't forget, accelerometer / gyros-based devices are essentially stupid. They make calculations based on comparing new data with what they did last, which is how drift can happen. Move and Wiimote+ simply demonstrate different ways of tackling the same problem.
