These investigations begin to break down the vast array of materials available to designers and too arrange these materials according to their proximal or potential relationships with the "RAW". The first organizes the materials by category and then breaks down the many sub-materials within each category. The second diagram begins to get at the sensory or haptic relationships these materials embody. Each of the materials was given a number characterizing its raw sensory stimuli. The diagrams show which materials might be used and in what ways they might be implemented.
