Tactile perception of the roughness of 3D-printed textures.
Surface roughness is one of the most important qualities in haptic perception. Roughness is a major identifier for judgments of material composition, comfort, and friction and is tied closely to manual dexterity. Some attention has been given to the study of roughness perception in the past, but it has typically focused on noncontrollable natural materials or on a narrow range of artificial mat...
متن کاملTemporal cues contribute to tactile perception of roughness.
Optimal perception of surface roughness requires lateral movement between skin and surface, suggesting the importance of temporal cues. The roughness of periodic gratings is affected by changing either inter-element spacing (groove width, G) or element width (ridge width, R). Peripheral neural responses to gratings depend quantitatively on a spatial variable, G, and a temporal variable, grating...
متن کاملSelective effects of auditory stimuli on tactile roughness perception.
We report two psychophysical experiments designed to investigate the effects of non touch-produced sounds on the tactile perception of roughness and length. Previous studies have demonstrated that the tactile roughness perception of object surfaces is modified by sounds elicited by rubbing the surfaces. In this study, we examined the crossmodal effects of non touch-produced sounds such as white...
متن کاملTactile Perception of Roughness and Hardness to Discriminate Materials by Friction-Induced Vibration
The human fingertip is an exquisitely powerful bio-tactile sensor in perceiving different materials based on various highly-sensitive mechanoreceptors distributed all over the skin. The tactile perception of surface roughness and material hardness can be estimated by skin vibrations generated during a fingertip stroking of a surface instead of being maintained in a static position. Moreover, re...
متن کاملEffects of Physical Bandwidth on Perception of Virtual Gratings
When exploring a virtual environment using a point interaction type force feedback interface, users are forced to adopt a method of ‘temporal encoding’ in order to classify textured surfaces, due to the lack of spatially distributed cues on the fingerpad. Dynamic modelling of haptic interfaces suggests that high spatial frequency information may be attenuated, such that discrimination of stimul...
