MapBag is a wearable bag with a small microcontroller, a GPS chipset, and a series of 8 vibration motors sewn into the bag. The microcontroller constantly evaluates the wearer’s current heading and the location of magnetic North, or the relative location of a user-defined waypoint (such as home). The microcontroller informs the wearer of compass information through the vibration motors, basically allowing you to read a compass with your body. This allows the user to re-experience the city and bike without distraction, navigating literally by feel rather than using street signs or depending on landmarks to discern their position in the city’s grid.
