Performance Capture

There are many different ways to capture a performer's motion. Here is a list of the current methodologies:

  • Optical: multiple cameras triangulate the position of spherical markers on the body
  • Inertial: sensors (accelerometer, gyroscope) on the body transmit wirelessly to PC
  • Mechanical: performer wears an exo-skeleton and measures motion with mechanical parts
  • Magnetic: position and orientation of performer derived by the relative magnetic flux
  • Computer Vision Based: captures motion in a volume without sensors.
  • Electroculography: captures eye movement with electrodes, and sensors placed around the eyes.

  • Mova Contour System: cameras capture movement by evaluating patterns in phosphor makeup on the actors face.
