Classic paper-based maps provide high-resolution, large-scale information and are ubiquitous in larger cities and even out- doors. In this paper we present a combination of their ad- vantages with a mobile camera projector unit to create a new mobile and intuitive buddy finder interface. Current friend or buddy finder systems on mobile phones such as Google Latitude suffer from the small screen estate and dis- play size of mobile devices. To overcome this problem we use a lightweight mobile camera projector unit to augment the paper map with a projected overlay of the buddies` positions. By using digital and geo-referenced representations of public maps no extra preperation for the tracking is needed. The idea is presented by enhancing Google Latitude, which al- lows users to browse the positions of their friends, to project the positions directly on the paper map without the cum- bersome panning and zooming of a digital map on a small display.
