Motion Capture CS 294 -7 Jacqueline Takeshita Mindy Lue

What is motion capture? Technique that digitally records movements using markers at joints l Software records positions, angles, velocities, accelerations, and impulses l Also known as motion tracking l

Where is it used? Education – how the body moves l Training – suggest ways to improve performance l Sports - simulations l Computer Animation l Video Games l

How it Works Mechanical – performer wears sensors l Optical – performer wears reflective dots followed by several cameras l Electromagnetic – performer wears an array of magnetic receivers which track location with respect to transmitter l

Advantages Saves time l Creates natural realistic movements l Actor can play multiple roles in a single film l Allows for rotating effects and multiple angles l Characters can be blended to digital environments l

Disadvantages Limited to movements that are anatomically possible l Specific hardware and programs needed to obtain and process data l Technology upgraded quickly – versions become obsolete every few years l Real life performance may not translate onto the computer model l
