For the EU project SOFIA (Smart Objects For Intelligent Applications), Bram van der Vlist and Gerrit Niezen created a demonstrator for one of the use cases: semantic connections. “The demonstrator consists of a set of devices; surround sound-set, mobile mp3 players, an ambient lighting system and interaction device(s). The interaction device is a tile-like interactive object that allows for both exploration of the Smart Space in terms of connections and manipulation of these connections and information/data streams. Coloured LED lighting and light dynamics visualize the connections and connection possibilities between the various devices. By means of putting devices close to one of the four sides of the tile, a user can check if there is a connection and if not if a connection is possible. By simply picking up the tile, and shaking it a user can make or break the connection between the devices present at the interaction tile.”
