Magrid Surface: An Interactive Display That Varies the Information by an Attached Magnetic Object

This paper presents a vertical interactive surface that can put out both analog and digital information and that can be used as a digital signage and community board in public spaces. Our proposed system uses a magnetic object to not only attach the analog information but also control the digital information. In this system, by attaching the object to the system surface directly, digital information appears. In addition, the system can selectively display the digital information by changing the level of importance. Our system uses multiple wavelengths of infrared light to achieve this function.
