Motion space reduction in a haptic model of violin and viola bowing

摘要

A haptic model of bowing the violin and viola is presented that focuses on just the geometry of the contact point between the bow hair and the string, giving a simplified description that focuses on aspects which the performer thinks about consciously. The model allows artificial constraints on the bow motion to be provided, giving the player physical feedback if one dimension of the contact point becomes incorrect, while allowing full movement in other dimensions.
