GPS track of a child on the schoolyard and inside the school building. Legend: Example of a child arriving at school in the morning, and entering and leaving the school building for school recess. Some of the activity recorded in the school building (blue) is projected as being on the schoolyard due to GPS inaccuracy indoors. The (yellow) pre-school segment ended when the child entered the school building (1). Likewise, the start (2) and ending (3) of the school recess segment were determined. The school recess segment is depicted as the red-colored track.
