This chapter explains the five types of perceptual dimensions in tactile perception of materials: namely, coarse and fine roughness, softness (hardness), warmness (coldness), and friction percepts. How these dimensions are specified is discussed, and the perceptual mechanisms of each dimension are outlined. Furthermore, experimental and analytical methods to specify these perceptual dimensions are introduced. Primarily, two types of analyses, factor analysis and multidimensional scaling, are described with appropriate experiments for data collection.
