iFloor, developed by Interactive Spaces, University of Aarhus (Denmark), is an interactive floor aiming at encouraging users to communicate with each other. They can ask and answer questions through SMS or email and have them shown in a public space.

The messages are registered by a server and displayed on the floor. Each question is marked with an ID reference number that is used when responding to the specific question. If someone answers a question the answer is both displayed on the floor and sent to the person who asked the question.

A remote server handles the questions and answers and a projector mounted on the ceiling connected to a local computer displays the messages on the floor. The floor works on the basis of a video tracking system observing the rim of the interface by means of a web cam mounted on the ceiling. The recordings of people’s position and movement are translated into magnetic forces attracting the cursor.
