HelloArrow - A Navigation System for Smooth Rendezvous using Compass Interface

In the days before cellphones, we have to wait at a fixed point for the partner till he or she comes. But now it does not matter where we spend a time till he or she comes, thanks for cellphones. Moreover we can leave a friend who is late, because cellphones helps their catching us up. Therefore it saves our frustration for waiting the partner and decreases a messy search for landmarks. But a new problem comes up. It is bothersome that looking for the partner, who is in unknown position, using only by cellphone. In this research, we propose and prototype a dynamic navigation system which leads directly from a movable user’s point to another movable user’s point using HelloArrow, the intuitive compass interface for comfortable smooth meeting.
