The first reference implementation of Digital Graffiti is a new location-based information- and communication system at the campus of the University of Linz. Students as well as lectors and administrative staff should be able to perceive location-based information on the university campus and to place information for other users. Lecture rooms should be marked by smart Digital Graffiti always displaying the current lecture type and times for these rooms. The event management should be able to announce upcoming activities or presentations to the users of this system. Teachers should be able to ad-hoc exchange documents with students just because of their geographical attendance in a lecture room. This reference implementation is called Smart Information Campus and enhances personal networking within the university campus.
