4 Department of Electrical and Computer Engineering PDR Recap NavFocus Mapping and Routing Control Unit Camera Road Tracking Overlay Renderer GPS Module User Interface Video Output User

5 Department of Electrical and Computer Engineering Mapping and Routing  Status Able to set destination via Town: Street input from the command line Send metrics to Overlay Rendering on position updates Distance from the next node Direction of the upcoming turn Speed at which the vehicle is traveling NavFocus Mapping and Routing Control Unit Camera Road Tracking Overlay Renderer GPS Module User Interface Video Output User

6 Department of Electrical and Computer Engineering Mapping and Routing  Navit Makes use of Multi-Threaded Plugins GPS Interrupts and fires a Callback which notifies the execute a navigation update. Example Plugins Navigation Speech Tracking NavFocus Mapping and Routing Control Unit Camera Road Tracking Overlay Renderer GPS Module User Interface Video Output User

7 Department of Electrical and Computer Engineering Mapping and Routing  Navit - Modifications Added a plugin to serve as a listener for user input string input of there desired destination Added a navigation callback which will be fired upon receiving GPS updates.
