In this video the user interacts with a navigation system by tapping the pen on a printed road map. The pen recognizes the tapped position and sends this information in real-time via Bluetooth to the navigation system (in this case represented by the laptop running our own Google Maps implementation). Since each sheet has a unique pattern printed on it the destination is recognized precisely. A navigation route is created and an acoustical freedback is given to the user providing the name of the destination (Text-To-Speech) or giving further instructions.
