Motion Maps????

  Motion maps was the hot topic in Battaglia's 1A class. We are still in the process of figuring out what the dots really represent.

Do the dots mean......
Position/distance
Direction
Duration/time

My thoughts- the dots mean.....
Duration/time
Direction
Speed

In the next class period I will be able to inform the bloggers reading this post what the class' concensus  on what the dots represent.
My only knowledge of motion maps is shown below.
