Haptic perception (Greek: haptόs "palpable", haptikόs "suitable for touch") means literally the ability "to grasp something", and is also known as stereognosis. Perception in this case is achieved through the active exploration of surfaces and objects by a moving subject, as opposed to passive contact by a static subject during tactile perception. [1]
Touch or haptics, from the ancient Greek word haptikos, is vital for survival. [3] Touch is the first sense to develop in the fetus. [4] The development of an infant's haptic senses and how it relates to the development of the other senses, such as vision, has been the target of much research.
Fine touch (or discriminative touch) is a sensory modality that allows a subject to sense and localize touch. The form of touch where localization is not possible is known as crude touch. The dorsal column–medial lemniscus pathway is the pathway responsible for the sending of fine touch information to the cerebral cortex of the brain.
Haptic technology (also kinaesthetic communication or 3D touch) [1] [2] is technology that can create an experience of touch by applying forces, vibrations, or motions to the user. [3] These technologies can be used to create virtual objects in a computer simulation , to control virtual objects, and to enhance remote control of machines and ...
The environment acts as an external stimulus, and tactile perception is the act of passively exploring the world to simply sense it. To make sense of the stimuli, an organism will undergo active exploration, or haptic perception, by moving their hands or other areas with environment-skin contact. [16]
The discriminative touch system deals with everything from the toes to the neck through the spinal cord. The sensation experienced enters the periphery by axons. More specifically, the sensory axons. This signal passes through axon to axon from the distal to proximal process. The proximal end of the specific axon leads into the spinal cord on ...
Haptic memory represents SM for the tactile sense of touch. Sensory receptors all over the body detect sensations such as pressure, itching, and pain. Information from receptors travel through afferent neurons in the spinal cord to the postcentral gyrus of the parietal lobe in the brain. This pathway comprises the somatosensory system.
Haptic perception relies on the forces experienced during touch. [24] Professor Gibson defined the haptic system as "the sensibility of the individual to the world adjacent to his body by use of his body." [25] Gibson and others emphasized the close link between body movement and haptic perception, where the latter is active exploration.
