Interaction with a display panel - An evaluation of surface-transmitted haptic feedback

This paper addresses the role of tactile feedback in touch-based interaction. The focus was on touch interaction on a surface as a natural interaction method and on surface-transmitted tactile feedback. The paper is an extension of previous research involving pin-array based tactile displays. For tactile impulses or vibrations, both a piezoactuator and a solenoid were utilized. A user can perceive discernable tactile impulses through the proposed actuators in a manner that differs from existing vibration motors. Psychophysical results also reveal that low-frequency vibrations or impulses can be used to create roughness on a smooth and nearly frictionless touch surface. A LDV (Laser Doppler Vibrometer), Ometron VH300, was utilized to measure the frequency responses of the surface vibrations and impulses. The rise time of the proposed system was less than 1 ms.
