“…Tactual Mode Active conditions of active or passive touch is consistent with earlier reports (Lamb, 1983;Lederman, 1981Lederman, , 1983. Active movement may play a greater role in form perception and spatial cognition, or in more difficult texture discrimination tasks when visual guidance is available (Heller, 1982).5…”

“…An experiment was performed to compare the accuracy of making smoothness judgments and roughness judgments, since many researchers have asked individuals to judge the roughness of surface textures (Jones & O'Neal, 1985;Lederman, 1981;Lederman & Abbott, 1981). In a repeated measures design, sighted observers (N =14) made judgments about the relative smoothness or roughness of abrasive surfaces.…”

Simplified soft tissue models used in surgical simulations cannot perfectly reproduce all material behaviors. In particular, many tissues exhibit the Poynting effect, which results in normal forces during shearing of tissue and is only observed in nonlinear elastic material models. In order to investigate and quantify the role of the Poynting effect on material discrimination, we performed a multidimensional scaling (MDS) study. Participants were presented with several pairs of shear and normal forces generated by a haptic device during interaction with virtual soft objects. Participants were asked to rate the similarity between the forces felt. The selection of the material parameters -and thus the magnitude of the shear and normal forces -was based on a pre-study prior to the MDS experiment. It was observed that for nonlinear elastic tissue models exhibiting the Poynting effect, MDS analysis indicated that both shear and normal forces affect user perception.

This chapter describes the psychophysics of touch—how tactile abilities and perceptions are measured, and what those measurements reveal about the somatosensory system. The ability to discern spatial aspects of tactile stimuli, such as how many are present and where they are on the skin, has been extensively studied: A key finding in this area is that resolution acuity predicts performance on a range of other tasks. Researchers have also examined temporal aspects of touch, especially through the use of vibration. Studies using masking and other paradigms have revealed the existence of vibrotactile channels associated with mechanoreceptor classes. Signals in these channels encode the intensity and frequency of vibratory stimuli, and contribute to the perception of textured surfaces. Many tactile stimuli involve temporal changes in spatial aspects of stimulation; an understanding of how these are perceived requires that a variety of spatio‐temporal distortions be taken into account. The chapter ends with a discussion of haptics (active touch) by which an attentive observer explores an object to discover its properties and identity. Kinesthetic as well as cutaneous signals play a role in this search for information, but how they are combined is a process that is only beginning to be understood.
