Roughness is a major identifier for judgments of material composition, comfort, and friction, and it is tied closely to manual dexterity. The advent of high-resolution 3D printing technology provides the ability to fabricate arbitrary 3D textures with surface geometry that confers haptic properties. In this work, we address the problem of mapping object geometry to tactile roughness. We fabricate a set of carefully designed stimuli and use them in experiments with human subjects to build a perceptual space for roughness. We then match 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. We demonstrate how this model can be applied to predict and alter surface roughness, and we show several applications in the context of fabrication.<\/jats:p>","DOI":"10.1145\/3186267","type":"journal-article","created":{"date-parts":[[2018,10,23]],"date-time":"2018-10-23T12:16:16Z","timestamp":1540296976000},"page":"1-14","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":22,"title":["A Quantitative Perceptual Model for Tactile Roughness"],"prefix":"10.1145","volume":"37","author":[{"given":"Chelsea","family":"Tymms","sequence":"first","affiliation":[{"name":"New York University, New York, NY, USA"}]},{"given":"Esther P.","family":"Gardner","sequence":"additional","affiliation":[{"name":"New York University School of Medicine, New York, NY USA"}]},{"given":"Denis","family":"Zorin","sequence":"additional","affiliation":[{"name":"New York University, New York, NY USA"}]}],"member":"320","published-online":{"date-parts":[[2018,10,23]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00406415"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2185520.2185585"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2461912.2461994"},{"key":"e_1_2_2_4_1","first-page":"67","article-title":"Exploring relationships between touch perception and surface physical properties","volume":"3","author":"Chen Xiaojuan","year":"2009","journal-title":"International Journal of Design"},{"key":"e_1_2_2_5_1","unstructured":"OpenStax CNX. 2017.
