Haptic discrimination of paper
This chapter describes a study on the haptic discrimination of different types of plain paper. The experiment is designed to replicate features of a ‘banknote’ scenario in which it may be possible to identify a counterfeit on the basis of only a few seconds contact. Multidimensional scaling (MDS) techniques are used to investigate the perceptual dimensions involved in the discrimination task. A related study of tactile perceptual space is summarised in Appendix 1.
