HAPTIC REACHING: CONTINUOUS VS. PULSED PARADIGM

Abstract

Haptic augmented feedback was found to enhance motor learning in healthy as well as impaired subjects. This pilot study describes experiments of haptic reaching, namely movements aimed at a target in the absence of vision, via haptic interaction. We provided healthy subjects with two types of force feedback, continuous in time vs. intermittent, directed towards 7 different target locations on a plane through a manipulandum. In particular, we sought for differences in force direction perception in the two force conditions and between the right and left arm. The results suggest that the new intermittent paradigm is at least as informative as the continuous one and that human force perception at the arm differs along different directions.
