metadata.conference.dc.description.abstract: Previous studies proved that in addition to spatial characteristics function in extracting roughness information, there are potential roughness dependability across changes in the temporal mechanisms of textured surfaces. In the present study, we created temporal coding mechanism by converting fine spatial structure surface into a temporal drifting pattern. We proposed that regular spatial structure of gratings with variation of temporal mechanism have different influence toward roughness perception. Results showed massive individual differences of roughness perception between subjects, suggesting that a combination of spatial and temporal mechanisms accounts for perceptual judgments of roughness. We suggest that visual roughness judgement was determined by spatial in grating stimulation, and improvement are needed in spatial components before temporal coding of visual roughness can be declared.
