GaussBricks is a novel building-block system for tangible interaction design that enables real-time constructive tangible interactions on portable displays. The simple mechanical design of the magnetic building blocks facilitates the construction of configurable forms. The forms constructed from the magnetic building blocks, which are connected by magnetic joints, allow users to stably manipulate them with various elastic force-feedback mechanisms. With an analog Hall-sensor grid mounted to its back, a portable display determines the geometrical configuration and detects various user interactions in real time. This work also introduces several methods to enable actuated shape changing, multi-touch input, and display capabilities in the constructed form. The proposed building-block system enriches how individuals physically interact with portable displays.
