PuyoSheet and PuyoDots: simple techniques for adding "button-push" feeling to touch panels

ABSTRACT

Two simple techniques for touch-panel based portable information devices are proposed. A soft-gel based transparent film named "PuyoSheet" placed over a touch panel provides button-push feeling to the fingertips. Another configuration, soft-gel based small dots, named "PuyoDots", is attached to the backside of a handheld device provides button-edge and button-push feelings to the fingertip(s) that hold the device. Preliminary evaluations indicate that proposed techniques improve "usability" and "preference" without deteriorating input speed or error rate compared with an ordinary touch panel device.
