Using an innovative system of ordinary objects combined with a series of magnets under each object, the Geckos system created at the Media Interaction Lab at the Upper Austria University of Applied Sciences demonstrates how to create flexible interactive objects our of ordinary shapes. It works by comparing pressure values at each point where a magnet is present in order to know where a person is pressing on the object. Projected images onto the top of the objects lets them react in real time to provide feedback and dynamic information.
