PitPat judges walking and running by sensing the natural gait motion of the dog. PitPat judges the difference between walking and running by the intensity/exertion. If a dog is constantly changing from walking, to running, to stopping and changing direction this is characteristic of many dog games and the activity is interpreted as playing. PitPat looks at the different activities over a 5-10 minute period and then classifies the activity as the one which was the most prominent in the period. For walking and running PitPat also looks at the consistency/regularity of the motion in the period of time to make sure it is owner initiated exercise that is counted towards the goal (as opposed to the dog pottering around the house).
