Haptic Perception of Material Properties and Implications for Applications
- PsychologyProceedings of the IEEE
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.
Haptic perception of friction—correlating friction measurements of skin against polymer surfaces with subjective evaluations of the surfaces' grip
A Quantitative Perceptual Model for Tactile Roughness
- Computer ScienceACM Trans. Graph.
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
- Materials ScienceIEEE Transactions on Haptics
It is concluded that tactile textures are composed of three prominent psychophysical dimensions that are perceived as roughness/smoothness, hardness/softness, and coldness/warmness.
Material recognition based on thermal cues: Mechanisms and applications
This review focuses on the mechanisms underlying material recognition based on thermal cues and provides an overview of the physical, perceptual, and cognitive processes involved in material recognition.

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
- BiologyIEEE Transactions on Haptics
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
- BiologyPerception & psychophysics
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
- PsychologyIEEE Transactions on Haptics
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
- PsychologyPerception & psychophysics
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.
Haptic discrimination of softness in teleoperation: the role of the contact area spread rate
- Computer ScienceIEEE Trans. Robotics Autom.
The possibility of surrogating detailed tactile information for softness discrimination, with information on the rate of spread of the contact area between the finger and the specimen as the contact force increases, is investigated.
Context effects in haptic perception of roughness
- PsychologyExperimental Brain Research
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.
Material identification using real and simulated thermal cues
- EngineeringThe 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society
Findings suggest that thermal feedback in a haptic display can facilitate object recognition when visual cues are limited, and this display was designed based on a semiinfinite body model.
The coding of roughness.
- BiologyCanadian journal of experimental psychology = Revue canadienne de psychologie experimentale
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…
