Haptic and visual perception of roughness
WebNov 22, 2024 · Surface roughness is one of the most important qualities in haptic perception. Roughness is a major identifier for judgments of material composition, … WebTo that end, our work proposes a method where the visual perception of roughness is integrated into the rendering algorithm of mid-air haptic texture feedback. We develop a machine learning model trained on crowd-sourced visual roughness ratings of texture images from the Penn Haptic Texture Toolkit (HaTT).

WebDuring the last two decades several haptic rendering approaches have been developed in order to acquit the visual feedback and allow users to fully exploit the coupling of these two sensory channels. Some skilful results have been archived. In this paper we present a survey on the use of the haptic modality in large data sets exploration. WebMay 1, 2013 · The influence of sensory modality and familiarity on roughness perception of dot pattern textures was investigated in a series of five experiments. Participants estimated the roughness of textures varying in mean center-to-center dot spacing in experimental conditions providing visual, haptic and visual–haptic combined information.
WebJan 1, 2001 · This paper describes experiments relating to the perception of the roughness of simulated surfaces via the haptic and visual senses. Subjects used a magnitude estimation technique to judge the roughness of “virtual gratings” presented via a PHANToM haptic interface device, and a standard visual display unit. WebIn fact, since the visual and tactile modalities seemingly provide independent information concerning roughness across a wide range of perceptual/discriminatory tasks, …
WebNov 22, 2024 · 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 …
