-|In each of the following methods, the direction of progression will need to be defined (Step 1). Once the direction of progression has been based off some measure, the user will need to determine what "progression" they are looking for. This means that if the subject walked in an arc (blue), does the user want to:\\ \\ - Calculate the average direction the subject traveled (red)\\ - Calculate the median direction the subject traveled (green)\\ - Calculate the difference between the start/stop position (purple)\\ \\ Obviously, it is rare that a subject is walking in a complete circle, but depending on the task, the user should choose the method that will result in the solution they are looking for.  |  {{DirectionofProg_Graph.png}}  |+|In each of the following methods, the direction of progression will need to be defined (Step 1).
