Portable multi touch tabletop: A composite approach for industrial applications

Digital tabletops are gaining increasing interest within commercial sectors both for home and office applications. These devices, with their multi-touch surfaces, can support collaborative activities while maintaining natural face-to-face communication. However, still one of the major problems is related to their portability and the space they require. We have conducted a study to explore how to design a novel architecture for surfaces that could operate in any environment without space limitations based on multiple tabletops. This paper presents an architecture based on the relative position of the tablets is proposed including an efficient data transmission system in order to obtain real time synchronisation and positioning of multiple tablets using a star topology.
