Designation (palpable) for the active sensing of weight, size, contours and surface texture of an object through integration of all senses of the skin and depth sensitivity. In particular, a distinction is made between the effects of touch, pressure, pain, temperature and vibration. The totality of haptic perceptions allows the brain to locate and evaluate the stimuli. To a certain extent, this is rated as pain or danger. A subarea are those perceived via the eponymous facial nerve trigeminal or tactile sensations in the odor and taste involved. Haptic and tactile are parts of the sense of touch (Latin tactus). The passive perception of mechanical impressions is also referred to as "tactile perception"; "haptic perception" is understood as active recognition. See also the other senses below gustatory (tasting), as well olfactory (Smelling).
