Full Body Motion Capture starting at $25,000! Affordable, tethered tracker for capturing human motions. 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 and workstation. 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 and can be bundled together for unhindered performance.


Tracks multiple characters simultaneously
  • Allows multiple characters to interact with one another.
DC magnetic technology
  • No data loss.

  • Less susceptible to metallic distortion than AC electromagnetic trackers.

  • Five times less susceptible to distortion caused by nearby metal than AC technology.
Real-time motion capture
  • Optimize productivity in motion capture sessions.

  • Choreograph movements instantly.

  • Instantaneous playback of motions.
Highly portable
  • Fast set-up, easy to use.
  • Quick return on your investment.
Works with all major animation software
  • Easily integrates into your current animation program.

Distortion and Noise Interference:

Ferrous metal in floors, walls and ceilings as well as noise sources in the motion-capture area can adversely affect measurements. To avoid problems, be sure to do the following:

  • Read, "What You Need to Do Before Your MoCap System Arrives." It provides important tips to minimize distortion and find and optimal location for your system.
  • You can purchase an Environmental Analyzer to sweep your capture area before installing the system. It will show you where to install the system to minimize metal effects and the best measurement rate to avoid 60/50Hz noise sources that can cause jitter.
