Abstract

We present the Force Attraction Pen, a haptic stylus that encourages the users to move in a particular direction by providing variable attraction force feedback based on their actions. The tip of the stylus is augmented with an electromagnet that can repel or attract the stylus to a metallic surface. By altering the polarity and voltage, we change the amount and direction of the force produced. The tactile expressions of the stylus may enable a higher grain of control during tasks such as tracing an image, performing selection, and other high precision tasks. In this paper we present the design and implementation of such a system, along with a formative study as a preliminary investigation into the haptic feedback generated by our system.
