Exploration de formes géométriques par le toucher

ABSTRACT

We propose a new technique to help people to explore geometric shapes without vision. This technique is based on a guidance using directional cues with a pin array. This is an alternative to the usual technique that consists of raising the pins corresponding to dark pixels around the cursor. In this paper we compare the exploration of geometric shapes with our new technique in unimanual and bimanual conditions. According to our results, the users made few errors in both conditions. Moreover the results show an equivalence for both techniques in answer time and users' confidence in their answer.
