Connectibition is an interactive surface that can be used for exhibitions. RFID technology is used to identify objects and create visualizations of the relationships between the selected exhibits on the surface.

Curators are faced with the task to arrange the exhibits in the existing premises and provide the relevant information. A particular challenge is to convey the various connections between the exhibits.

The project “Connectibition” allows visitors to playfully discover these relationships and understand the relevant information. Exhibits or their replicas can be placed on an interactive surface, whereupon the information for that object is visualized, using images, text or animations. If there are several objects on the surface, the features they have in common are highlighted and linked to each other.

RFID technology is used for object detection. RFID chips are hidden inside the objects; they interact with RFID readers, which are integrated in the table. If an object is moved to the immediate vicinity of a reader, the tag is sending signals to the reader which passes them forwards to a microcontroller, where the intermediate processing is handled. Afterwards the preprocessed signals are sent to a PC, which calculates the visualization that is projected to the surface by a projector. The more readers are installed, the more exhibits can be connected with each other and the more visitors can interact with the installation simultaneously.

The technology can be adapted to the scope and depth of information. The concept is transferable to the various subject areas, as long as exhibits or matching replicas for the visitor can be made tangible.
