Selective 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 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 کاملTactile 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 کاملTwo phase effects in roughness perception.
The respective influences of spectral and temporal aspects of sound in roughness perception are examined by way of phase manipulations. In a first experiment, the phase of the central component of three-component signals is shown to modify perceived roughness, for a given amplitude spectrum, regardless of whether it modifies the waveform envelope. A second experiment shows that the shape of the...
متن کاملThe Application of Tactile Experience in Urban Perception
Urban perception is the result of mutual transaction between human and environment and the process of perception is developed through the three continuous steps of “sensation”, “perception” and “cognition”. In the first step (sensorial perception), the environmental signals are received via sensorial sensors and each different sense based on its own essence, performance and ability has its own ...
