Abstract

We propose a method using vacuum suction force to provide a force feedback sensations to fingers moving across a touch panel. The device consists of a vacuum suction pressure generating device using a pneumatic cylinder and a perforated sheet that can attach to a fingertip. When the finger moves across a touch panel, control the frictional force by generating a vacuum suction force between the perforated sheet attached to the fingertip and the touch panel, and provide the force feedback sensation to the fingertip. The device using the method can provide a rich force feedback on any size touch panel without changing the configuration of the device.
