LiveMove2 from AiLive isn’t a new device; instead, it’s a new middleware package designed to take advantage of Wii MotionPlus. The first version of LiveMove is used in a number of commercial games including We Cheer. Representatives said one of the biggest difficulties in developing the new version of the software was that Nintendo kept changing the firmware interface on them, which meant they had to update their software in turn.

LiveMove2 includes two modes, motion control and gesture recognition. They had demos of both on show. The first put users in control of a light saber, which rotated around in 3D as the user did. Another part of this demo placed a ball at the end of the saber, which could be flung into objects down screen. The software sampled for a short period of time to determine the angle and velocity to throw the ball.

The gesture recognition technology was demoed as a simple game. Numbered bombs fell from the top of the screen and players had to hold a button and draw out the number to eliminate the attack. The game showed which number the system was predicting based on the gestures. The gesture system worked quite well considering that its training set was relatively small; about 40 examples of each number were used.
