  > quantize the angle Round the angle quite severely. E.g. if using 10 degree steps you'd round anything below 5 degrees to 0 degrees, and anything above to 10 degrees. Anything above 15 would get rounded to 20, and so on. > look at the event stream Look at the last two directions the above procedure generated. > and take the sign of the pairwise difference If the new angle is higher it's a counterclockwise motion. If the new angle is lower it's a clockwise motion. Do some special handling if the angle wraps around from 350 to 0 degrees or vice versa.
