The company that worked with Nintendo on the MotionPlus controller add-on, has now released a video that demonstrates the capabilities of the new hardware using 3D tools called LiveMove2. Turns out that the 1:1 tracking is really 1:1. Also the response time is pretty instant.

Before you know it they’re playing with lightsabers and fighting off Seeker Drones, then tossing around a 3D dummy with the lightsaber. All in all a lot of fun. The end result is that this technology can map incredibly complex motions to even more specific commands then before. It’s pretty damn impressive.

Looks like Wii Sports Resort, which is basically Wii Sports: The Next Generation, will come bundled with the MotionPlus accessory, when it becomes available next spring. The MotionPlus attachment gives you 1:1 motion mirroring on your Wiimote.

No word yet on the price of the MotionPlus by itself, but the thinking is that people will buy Wii Sports Resort just to get the accessory just like with Wii Play.

Nintendo today issued a press release to introduce an unexpected accessory to the Wii Remote controller, called Wii Motionplus. The new attachment is designed to give even more accurate responses to a players hand and arm motions and we hope will lead to a lightsaber game in the very near future. According to Nintendo, the new controller add-on connects to the bottom end of the Wii Remote and will do a better job of “reflecting motions in a 3-D space”.

The attachment works in conjunction with the existing accelerometer in the remote and the Wii Sensor bar to track the players hand and arm motions and give what Nintendo is calling a true 1:1 response, which is sure to be a welcome feature for those interested in first person shooter games or anything requiring a little more precision beyond shaking or waving the remote wildly. The Wii remote currently with the game console does a great job of sensing more general motions, twisting and waving but sometimes can be a little shaky with the direct pointing. The Wii MotionPlus is sure to be an improvement and open up the Wii to less frustrating times at games requiring more precision.
