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]
Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. The word haptic, from the Ancient Greek: ἁπτικός (haptikos), means "tactile, pertaining to the sense of touch". Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels.
Tactile technology is the integration of multi-sensory triggers within physical objects, allowing "real world" interactions with technology. It is similar to haptic technology , as both focus on touch interactions with technology, but whereas haptic is simulated touch, tactile is physical touch.
This photo shows tactile markings identifying stairs for visually impaired people. The somatosensory system , or somatic sensory system is a subset of the sensory nervous system . It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [ 1 ]
Braille is a tactile written language which is read via touch, brushing the fingers over the raised patterns. Braille technology is the attempt to extend Braille to digital media and developing new tools to aid in the reading of web pages and other electronic devices often involves a combination of haptic and auditory cues.
Haptic memory is the form of sensory memory specific to touch stimuli. Haptic memory is used regularly when assessing the necessary forces for gripping and interacting with familiar objects. [ 1 ] It may also influence one's interactions with novel objects of an apparently similar size and density.
Haptic communication is nonverbal communication and interaction via the sense of touch. Touch can come in many different forms, some can promote physical and psychological well-being . A warm, loving touch can lead to positive outcomes while a violent touch can ultimately lead to a negative outcome.
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.
