HAPTIC ASSESSMENT OF VOLITIONAL EFFORT

Dalia De Santis, Jacopo Zenzeri, Pietro Morasso

Abstract

This study describes pilot experiments of haptic reaching, namely movements aimed at a target in the absence of vision, via haptic interaction. A manipulandum generates a convergent force field which transmits the direction of the target to the subject. The field has a very low intensity, close to the perceptual threshold, and it is pulsed in time, with a smooth profile (0.2 s duration) and a repetition rate of 2 pulses/s. In particular, we developed and tested a novel method for evaluating the degree of active participation to this haptic interaction which may find application in robot therapy of stroke patients and in the design of efficient haptic interfaces.
