A New Approach for Realistic Vibrotactile Friction Feedback for Midair Writing Systems.

抄録

Realistic haptic feedback can greatly improve user satisfaction in midair interaction systems. In this paper authors propose a new approach for more realistic vibrotactile friction feedback during midair handwriting. Experimental study to analyze the modulation of normal force of finger during writing on a real screen revealed the dependence of finger direction and velocity during the writing of different characters. A new vibrotactile friction rendering model was developed to recreate the normal force modulation in midair writing using cues from finger motion. An experimental evaluation of the developed rendering system on 4 subjects showed promising results.
