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 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.
The information stored in SM is modality specific. This means, for example, that echoic memory is for the exclusive storage of auditory information, and haptic memory is for the exclusive storage of tactile information. Each SM store represents an immense amount of detail resulting in very high resolution of information.
The stimulus modality for vision is light; the human eye is able to access only a limited section of the electromagnetic spectrum, between 380 and 760 nanometres. [3] Specific inhibitory responses that take place in the visual cortex help create a visual focus on a specific point rather than the entire surrounding.
The process of recognizing objects through touch is known as haptic perception. It involves a combination of somatosensory perception of patterns on the skin surface (e.g., edges, curvature, and texture) and proprioception of hand position and conformation. People can rapidly and accurately identify three-dimensional objects by touch. [22]
Sensory substitution is a change of the characteristics of one sensory modality into stimuli of another sensory modality.. A sensory substitution system consists of three parts: a sensor, a coupling system, and a stimulator.
In addition to the interplay of haptic communication and nonverbal communication, haptic cues as primers have been looked at as a means of decreasing reaction time for identifying a visual stimulus. [20] Subjects were placed in a chair fitted with a back which provided haptic cues indicating where the stimulus would appear on a screen.
Multisensory integration, also known as multimodal integration, is the study of how information from the different sensory modalities (such as sight, sound, touch, smell, self-motion, and taste) may be integrated by the nervous system. [1]
