This can detect an explicit lane change, but can't tell where you turned; if you make a right turn, it can't tell which lane you turned into. It would probably work on expressways with moderate traffic, where lane changes are usually made explicitly, one lane at a time.

You can do car navigation entirely from gyros, accelerometers, and wheel rotation counts, without GPS, if you have even moderately accurate map data. Etak had that working in 1985. I still have one of their original gyros.

Our purpose is to make a library that could be used by any driver without additional equipment, therefore we work only with the sensors available in a phone. Accelerometer and gyroscope installed in it are not precise enough to track position of car. Wheel rotation can't be measured of course by a phone.
