THAT LITTLE blue dot likes to mock. Glowing bright on a smartphone’s map, it’s usually a reliable marker of the user’s location. Except when it’s not. Anyone who’s tried to use it to navigate out of a mall can attest to the frustration of the blue dot just pretending to know which way she’s facing or where she is (no, not in that river two blocks away!). The consequences of using the wrong exit out of a shopping center are minimal, but when it’s a firefighter trying to make her way out of a burning building, the stakes for tracking her precise location and orientation are high.
