MotionStar®

Full Body Motion Capture for under at $25,000! Affordable, tethered tracker for capturing human motions and emotions. MotionStar is the most cost-effective means of tracking full-body motions in the world today.Developed with animators world-wide, MotionStar is a "turn-key" motion-capture solution when purchased with appropriate animation software. It comes in a fully-integrated enclosure with a fast Ethernet interface to your computer.

The rack-mounted chassis houses all electronics and a high speed interface to your host computer. Each sensor is connected to the chassis by a 35-foot cable.
