iPi Biomech Add-on is a convenient tool for in-depth biomechanical analysis of human motions. It includes visualization of tracking data and its export to various formats. It can be used for:

  • Gait analysis and rehabilitation
  • Sports motion analysis
  • Research in 3D human kinematics

Markerless tracking technology does not require clumsy suits, and work in real-life environments like regular office.

With iPi Biomech Add-on you can:

  • Get linear and angular quantities for selected bones, including
    • Linear coordinate, velocity, acceleration
    • Euler angles, angular velocity and angular acceleration
    • Quaternions and rotation matrices
  • Select convenient coordinate systems
    • Linear: Absolute (relative to floor), Relative to parent joint, Relative to center of mass
    • Angular: Absolute (relative to floor), Relative to parent joint
  • Select Euler angles system
  • Plot values of selected quantities for selected bones
  • Export bones motion data to tab-separated text for Excel or MATLAB
  • Export point clouds obtained from depth sensors to PCD or MATLAB

See Product Overview page for publications on research made with iPi Biomech.

Biomech Add-on does not impose additional system requirements. So the system requirements are the same as for iPi Motion Capture edition you are using.

Frequently Asked Questions

  1. What is the accuracy of the tracking?
    – The overall accuracy is comparable with the accuracy of expensive marker mocap systems. We do not yet have precise numbers on accuracy, as this is the question of special research.
  2. What export formats can I export data to?
    – You can export bones motion data to tab-separated text format for Excel, and to MATLAB. Point clouds can be exported to PCD and MATLAB.
  3. Can I export to C3D?
    – Current version does not yet include export to C3D.
