Van Egmond, R. (author), Pappas, T.N. (author), De Ridder, H. (author)In a previous study we investigated the roughness of real world textures taken from the CUReT database. We showed that people could systematically judge the subjective roughness of these textures. However, we did not determine which objective factors relate to these perceptual judgments of roughness. In the present study we take the first step...conference paper 2010

Van Egmond, R. (author), Lemmens, P. (author), Pappas, T.N. (author), De Ridder, H. (author)In three experiments the perceived roughness of visual and of auditory materials was investigated. In Experiment 1, the roughness of frequency-modulated tones was determined using a paired-comparison paradigm. It was found that using this paradigm similar results in comparison to literature were found. In Experiment 2, the perceived visual...conference paper 2009
