Generic Properties of Curvature Sensing through Vision and Touch

Figure 3

A photograph of the veridical real-world counterparts of the virtual curves, with identical 𝐻 and 𝑊 (in centimetres), used in the tactile experiment. As in the visual experiment, curves were presented in random order and curve orientation (curve placed into the two hands of an observer with upward and downward orientation) also varied randomly. Only upward orientation is shown here in this photograph.
