Humans are endowed with a highly developed vision system, and nowadays the technical aids for creating imagery are available too. Hypermedia systems represent the technology by means of which it is possible to produce easily and naturally concrete and abstract projections of human mental images by computer. The delivery system and visual interface of visual media, capable of supporting interactivity while facilitating at the same time interconnectivity of images and symbols, has a potential to become an extremely powerful virtual board presentation tool. The paper describes an interactive display system on the screen as a virtual board visual interface. The sophisticated design enables the viewer's good orientation in the screen (virtual board) with a full personal interactivity for every member of the group auditorium. Describe a system which improves the interaction between many subjects in front of the visual interface. It is open to the use of collaborative scientific and educational visualization.
