  14. 14. Shooting the Apple, Harold Edgerton, 1964Milk-Drop Coronet, Harold Edgerton, 1957
  15. 15. 1. Optical Mocap Systems2. Magnetic Mocap Systems3. Mechanical Mocap Systems
  16. 16. 1. Designed for medical application2. Developed with CGI application – Vicon 8 system.3. 4 to 32 cameras controls by computer.4. Subject wears markers (Active & Passive).
  17. 17. 1. Magnetic Trackers.2. Derived from the sensors placed on military aircraft pilots helmet to track the pilot head position and orientation for the helmet-mounted display.3. 12-20 tracking sensors are placed on a captured subject.4. Tracking sensors output their translation and orientations.5. Divide into two groups 1. Direct Currant (DC) 2. Alternating Currant (AC)
  18. 18. 1. Directly Measure joint angels of a capture subject.2. Designed to measure joint angles as the capture moves.3. Device look like an exo-skeleton.4. Mechanical system are real time, relatively inexpensive, free of occlusion, free from magnetic or electrical interference and highly portable.5. Wireless mechanical system.
