Multimodal motion guidance

The ability to guide human motion through automaticallygenerated feedback has significant potential for applicationsin areas, such as motor learning, human-computer interaction, telepresence, and augmented reality.This paper focuses on the design and development of suchsystems from a human cognition and perception perspective. We analyze the dimensions of the design space for motion guidance systems, spanned by technologies and human information processing, and identify opportunities for new feedback techniques.We present a novel motion guidance system, that was implemented based on these insights to enable feedback for position, direction and continuous velocities. It uses motion capture to track a user in space and guides using visual, vibrotactile and pneumatic actuation. Our system also introduces motion retargeting through time warping, motion dynamics and prediction, to allow more flexibility and adapt-ability to user performance
