A chassis houses a marking engine, a scanner, and various input and output ports allowing devices to connect to the hub for data transfer, sharing, and collaboration. The preferred configuration includes two towers with a display and a work surface supported therebeteween. The display can have another display on its rear face, and both can have cameras and microphones mounted thereon, as well as speakers. The scanner is preferably embedded in the work surface. The towers house various components of the hub. A base can be included that supports both towers and any users using the hub. Preferably, the base includes pressure sensors to let the hub know when users are present.
