Abstract
There is provided a system and method for database driven action capture. By utilizing low cost, lightweight MEMS devices such as accelerometers, a user friendly, wearable, and cost effective system for motion capture is provided, which relies on a motion database of previously recorded motions to reconstruct the actions of a user. By relying on the motion database, calculation errors such as integration drift are avoided and the need for complex and expensive positional compensation hardware is avoided. The accelerometers may be implemented in an E-textile embodiment using inexpensive off-the-shelf components. In some embodiments, compression techniques may be used to accelerate linear best match searching against the motion database. Adjacent selected motions may also be blended together for improved reconstruction results and visual rendering quality. Various perceivable effects may be triggered in response to the reconstructed motion, such as animating a 3D avatar, playing sounds, or operating a motor.
