Generic Properties of Curvature Sensing through Vision and Touch
Table 1
Mathematical parameters of the eleven curves (stimuli) in terms of width (), sagitta (), expressed in centimetres, and the scale-invariant aspect ratio (), as defined here in the introduction. Parameters of virtual curves presented on a computer screen to one group (visual experiment) and their real-world counterparts used for tactile sensing by another group of blindfolded or congenitally blind observers (tactile experiment) were the same.
