I BELIEVE what was demoed at the kickoff (not 110% sure) was the accelerometer. An accelerometer gives back a reading that tells how fast you are accelerating, i.e. changing speed, in a given direction. Using some programming, you can sense when you are moving and take steps to remedy it. A hall-effect sensor uses a magnetic field to detect a metallic presence, and therefore does not return angular headings. I am pretty sure they put out pulses when a metallic presence is detected. It's just an FET, in other words.
