Haptics is a term relating to touch, and active touch in its widest context, and how we are able to gain information about objects by manipulating them. Haptic perception involves the sensing of the movement and position of joints, limbs, and fingers, and also the sensing of information through the skin. The word ‘haptics’ is derived from the Greek term haptikos, from haptesthai, meaning ‘to grasp, touch, or perceive’, which is equivalent to hap(tein) to grasp, sense, or perceive.
