Abstract

This paper presents an ongoing proposal to enhance traditional multivariate data visualization by adding haptic representation for the data. By combining visual and haptic stimuli one may alleviate the information overload typically found in situations where a large number of variables are mapped to the visual channel alone. In this paper we report the results of a user study in which we compared five haptic effects---magnetism, stiffness, stickiness, viscosity, and vibration---in an attempt to classify them in terms of perceivability. By perceivability we mean the degree of success in correctly detecting differences of stimulus intensity, given a pairwise stimuli of the same haptic effect. The results showed that magnetism and stiffness presented the worse results, while vibration, stickiness, and viscosity, in that order, were best perceived by the participants.
