Active click: tactile feedback for touch panels

ABSTRACT

"Active Click" is a new interface mechanism for addling tactile feedback to touch panels. A small actuator is attached to a body of PDA or the backside of a touch panel. The tactile feedback, created by driving the actuator with a short pulse, is perceived by the grasping hand or tapping finger-tip when the panel is tapped. Active Click is effective in improving the input speed of touch panel operation especially in noisy situations. Active click is also useful for large touch panel devices such as public information terminals or ATMs.
