Perceptual deadband is a region which captures perceptual limitations of human perception. Thus gathered object or subject properties are size, weight, contour, surface and material characteristics, consistency and temperature.Īlong with the development of tactile sensors, some work has been dedicated to training robots exploratory procedures. The following exploratory procedures have been identified so far: They do so through the use of exploratory procedures, such as moving the fingers over the outer surface of the object or holding the entire object in the hand. People can rapidly and accurately identify three-dimensional objects by touch. This research allows the creation of 'virtual', illusory haptic shapes with different perceived qualities, which has clear application in haptic technology.

Haptic perception relies on the forces experienced during touch. The concept of haptic perception is related to the concept of extended physiological proprioception, according to which when a tool such as a stick is used, perceptual experience is transparently transferred to the end of the tool. Gibson and others further emphasized what Weber had realized in 1851: the close līetween haptic perception and body movement, and that haptic perception is active exploration. Gibson (1966) defined the haptic system as 'he sensibility of the individual to the world adjacent to his body by use of his body'. The term haptik was coined by the German Psychologist Max Dessoir in 1892, when suggesting a name for academic research into the sense of touch in the style of that in 'acoustics' and 'optics'. 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. Haptic perception ( Greek: haptόs 'palpable', haptikόs 'suitable for touch') means literally the ability 'to grasp something'.
