in order to understand the effects of degrees of impact on flat planes and inclined/declined planes through walking, running and skipping, a mapping was created. by painting my feet different colors and walking, running and then skipping over a strip of fabric, i was able to understand not only the level of impact of each activity through the opacity of the footprint, but also the patterning of prints and their relationships. the walking prints were less opaque than the running prints because i create a higher impact while running than walking. it was interesting to throw the skip in. it occurred along with the running prints, but of course it included an extra upper foot pad print representing the extra small jump of a skip. this mapping was then translated into a coding system of impact and also physical exertion the body understands with each activity. because exertion is a more internal perception of how much work is being done, it was a more intuitive abstract mapping that coincided with the impact part.
