2A2-A12 Thickness-Dependent Friction Effect : Measurement and Consideration of Force at the Surface of Swiping Finger(Tactile and Force Sensing (2))

Abstract

This paper reports a haptic effect that feeling of friction to swipe a screen of smartphones changes depending on their thickness and weight, even if the screens are covered with the same surface materials. The reason of the effect should be related to holding position and required force to hold it. Therefore, in order to clarify the effect, we measured the force generated between the object and finger, and orientation of the finger is also observed.
