Abstract

Touch screens offer advantages for mobile interaction: large, rich graphical displays and powerful multi-touch input. However, they lack inherent haptic feedback to match this expressiveness. One recent approach to this problem has been to actuate glass plates at high frequency to controllably vary surface friction. This paper extends this work by describing vibration beating, a novel haptic actuation method that increases the range of cues that can be rendered via dynamic variations of surface friction. In order to understand how users perceive the cues it produces a set of 16 stimuli were chosen and two studies that generate and interpret a perceptual map are described. Three distinct clusters of tactile cues are identified, delimited and named. These groupings will form the basis of future work to develop interfaces and interaction techniques based on the vibration beating actuation method.
