Scientific study of perception and manipulation of objects through touch and proprioception, usually for control purposes. As it relates to musical instruments, haptics considers the sensory and mechanical interaction between performers and acoustic, digital, or virtual instruments. Skilled instrumentalists demonstrate significantly greater tactile sensitivity and faster response time than members of the general population. Vibrations, acoustic response, and feedback forces inform players about an instrument’s state, speeding learning and improving control. Researchers try to measure feedback forces and determine which can be perceived and which are important to a player’s sense of control and expressivity. Haptics considers the complete circuit from the moment a player engages an activating component of an instrument until the interaction ceases. This consideration extends to a sequence of such events as the instrument’s mechanisms and player repeatedly respond to each other. These interactions can be termed ‘gestures’ and the input device (such as a keyboard) the ‘gesture controller.’...
