title: New technique for acquiring three-dimensional orofacial nonspeech movements.
abstract: A new video-based motion analysis system is described that permits acquisition of kinematic patterns from multiple structures (upper lip, lower lip, and jaw), movement patterns to be captured in three dimensions, and acquisition of non-speech orofacial movement patterns without restricting natural head motion. The importance of acquiring three-dimensional lip and jaw movements during nonspeech (e.g., oral opening-closing and chewing motions) movements is emphasized.
