We developed a custom tangible that uses LED arrays around the edges as a low-resolution display to provide real-time visual feedback on the current state of the system. We developed a guideline for mapping different types of edge feedback to different tangible interactions. We evaluated its effectiveness in an informal user study where users interacted with a tabletop and tangible system with the edge feedback enabled. Results suggest that edge feedback provides a better understanding of the system.
