Development and Experimental Validation of a Haptic Compass Based on Asymmetric Torque Stimuli
By Jean-Philippe Choiniere and Clement Gosselin
This paper presents the design, control, and experimental validation of a haptic compass, designed as a guiding device for all environments. The proposed device uses the principle of asymmetric torques. Its design is based on a direct drive motor and a pre-calibrated open-loop control, which allows the generation of stimuli in a wide range of frequencies. User studies are presented and show optimum effectiveness in the frequency range 5-15 Hz and for torques over 40 mNm. The use of a haptic feedback proportional to the angle error is then shown to significantly improve the results. An experimental validation by a group of‘ subjects with the portable device using these stimuli is reported. The results show that all subjects met all route objectives with small lateral deviations (avg. 0.39 m).
