Force Feedback Slider: An interactive device for learning dynamic system behavior

Paper in proceeding, 2005

Physics education often relies on visualization of theoretical laws. While Java animations are widespread, they mostly lack user interaction. We propose a haptic device inviting users to interact with the law of physics. Based on an in-house design — a generic force feedback slider (FFS) — we have realized a software application simulating a catapult. As users interact, they receive both tactile and visual feedback. By calling upon two perceptual channels at a time, here tactile and visual, we assume users may construct their mental model more easily. This paper presents our application, the underlying FFS technology, a user study, future uses, and a discussion.
