Basic Analysis of Stickiness Sensation for Tactile Displays

This paper analyzes fingertip behavior on sticky surfaces for synthesizing stickiness sensation. Changes of fingertip contact area were monitored during contacts to sticky surfaces, which were then analyzed with respect to contact force. The analysis revealed that stickiness surfaces cause large hysteresis on the relationship between contact force and area. Based on the analysis, the sticky sensation was simply synthesized by using vacuum pressure. The synthesized sensation elicited a similar feeling as sticky sensation caused by adhesive glue, although the sensation was weaker than the intended one.
