when you accerlerate, save the accerleration and then calculate the speed you are walking. Stop calculation of speed whenever the acceleration changes and start over. If you stop, you should receive a negative accerleration, you'd then have to calculate if you just slowed down or stopped completely. But thats simply math :)
