A tap close to the center of the screen will not move the phone much, will reach both microphones at the same time, and will sound roughly the same to all the microphones. However, a tap at the bottom left edge of the screen will rotate the phone left and down; it will reach the left microphone faster; and it will sound louder to microphones near the bottom of the screen and quieter to microphones elsewhere on the device.

The route taken by a driver, for instance, can be simplified into a series of turns, each in a certain direction and with a certain angle. And the accelerometer showed whether a user was stopped, or moving. By measuring a sequence of turns, and stringing them together as a person travels, we could make a map of their movements.
In our work, we knew which city we were tracking people through, but a similar approach could be used to figure out what city a person was in. Matching the route of a smartphone with a trip through Boston. Google Maps , CC BY-ND ] Imagine we observe a person in Boston heading southwest , turning degrees to the right, making a sharp U-turn to the left to head southeast, turning slightly to the right, continuing straight, then following a shallow curve to the left, a quick jog to the right, bumping up and down more than usual on a road, turning 55 degrees right, and turning 97 degrees left and then making a slight curve right before stopping.
We developed an algorithm to match those movements up against a digitized map of the streets of the city the user was in, and determined which were the most likely routes a person might take. We were even able to refine our algorithm to incorporate information about curves in roads and speed limits to help narrow options.
We produced our results as a list of possible paths ranked by how likely the algorithm thought they were to match the actual route.
