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 technology facilitates investigation of how the human sense of touch works by allowing the creation of controlled haptic virtual objects. Most researchers distinguish three sensory systems related to sense of touch in humans: cutaneous , kinaesthetic and haptic .
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.
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.
Roberta "Bobby Lou" Klatzky is a Professor of Psychology at Carnegie Mellon University (CMU). She specializes in human perception and cognition, particularly relating to visual and non-visual perception and representation of space and geometric shapes.
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]
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]
Lederman's research has examined, among other topics, the tactile psychophysics of texture perception, [4] [5] and the haptic processing of objects [6] [7] and faces. [8] [9] She led a research project to design and test the addition of a tactile feature to Canadian banknotes, in order to increase their accessibility to blind and visually ...
