Enhancing Human-Computer Interaction via Electrovibration
We present a compact tablet that displays electrostatic haptic feedback to the user. We track user's finger position via an infrared frame and then display haptic feedback through a capacitive touch screen based on her/his position. In order to demonstrate practical utility of the proposed system, the following applications have been developed: (1) Online Shopping application allows users to be able to feel the cord density of two different fabrics. (2) Education application asks user to add two numbers by dragging one number onto another in order to match the sum. After selecting the first number, haptic feedback assists user to select the right pair. (3) Gaming/Entertainment application presents users a bike riding experience on three different road textures -smooth, bumpy, and sandy. (4) User Interface application in which users are asked to drag two visually identical folders. While dragging, users are able to differentiate the amount of data in each folder based on haptic resistance.
