Tactual perception of liquid material properties

Haptic Perception of Material Properties and Implications for Applications

This work reviews major material properties accessible through haptic interaction, along with theoretical accounts of the underlying perceptual processes, including roughness, friction, compliance, and thermal properties.

Psychophysical Dimensions of Material Perception and Methods to Specify Textural Space

This chapter explains the five types of perceptual dimensions in tactile perception of materials: namely, coarse and fine roughness, softness (hardness), warmness (coldness), and friction percepts, and the perceptual mechanisms of each dimension are outlined.

A Quantitative Perceptual Model for Tactile Roughness

This work fabricates a set of carefully designed stimuli and uses them in experiments with human subjects to build a perceptual space for roughness, and matches this space to a quantitative model obtained from strain fields derived from elasticity simulations of the human skin contacting the texture geometry, drawing from past research in neuroscience and psychophysics.

Psychophysical Dimensions of Tactile Perception of Textures

It is concluded that tactile textures are composed of three prominent psychophysical dimensions that are perceived as roughness/smoothness, hardness/softness, and coldness/warmness.

The perception of surface roughness by active and passive touch

Subjects made magnitude estimates of the roughness of metal gratings by both active and passive touch (with object movement). The perceived magnitude of surface roughness and the consistency of such

Cues for Haptic Perception of Compliance

The relative roles of force/displacement and surface deformation cues are investigated and measured discrimination thresholds with silicone rubber stimuli of differing thickness and compliance found that differences in object thickness are correctly taken into account.

The role of vibration in the tactual perception of roughness

Although prior (selective) adaptation of the fingertip strongly affects the perceived magnitude of supraliminal vibrotactile signals, it fails to alter the perceived roughness of metal gratings, and the results thus favor the Taylor and Lederman position.

Rendering Softness: Integration of Kinesthetic and Cutaneous Information in a Haptic Device

The ambiguities that arise in unimodal touch are discussed, and a simple intuitive explanation in terms of basic contact mechanics is provided in order to investigate the effectiveness of the integrated haptic display and compare the subjective perception of softness with that obtained by direct touch on physical objects.

Manual exploration and the perception of slipperiness

There was a dissociation between haptic perception and motor output, and the issue of how humans are able to generate the appropriate forces in response to friction during grasping was raised.

Context effects in haptic perception of roughness

The influence of temporal and spatial context during haptic roughness perception was investigated in two experiments and showed that adaptation to a rough surface decreased the perceived roughness of a surface subsequently scanned with the adapted finger, whereasAdaptation to a smooth surface increased the perceivedroughness.

This review examines the way information about textures is captured, encoded, and processed by the somatosensory system to produce sensations of roughness/smoothness. Textures with spatial periods

Tactual discrimination of softness.

The ability of humans to tactually discriminate the softness of objects, using novel elastic objects with deformable and rigid surfaces, is investigated, and all the human subjects showed excellent softness discriminability in ranking the rubber specimens by active touch, and the subjective perception of softness correlated one-to-one with the objectively measured compliance.
