We describe the design of an interactive concrete floor display for public spaces and discuss its implementation and areas of application. The primary purpose of our system is to provide new forms of collaborative interaction in long-term installations in both indoor and outdoor spaces. Our design is an expandable system of interconnected tiles, which control an array of RGB Light-Emitting Diodes (LEDs) based on user input. The LEDs are built into the tiles and arranged in a manner that simulates pixels on a computer screen, providing a natural visualization mechanism. Each tile acts as an independent node in a network, where motion sensors trigger specific actions and provide interactivity to the surface. A series of applications are illustrated, including promotional advertising and interactive games. The system was installed and evaluated on a university campus for four weeks where hundreds of visitors successfully interacted with the floor.
