P4 Ideation

Our P4 process included iterations in two main categories (with only minor software changes) ->

1. The Squeezers themselves. We experimented with a wide-range of squeezables: pieces of cardboard, raisin boxes, water bottles, staplers, sponges, pliers, tennis balls, bubble wrap, tangles of cable, etc. We selected our favorites among these items and more and tested them with Stanford students. The favorite was a specific pair of pliers (pictured above) and we used this as our final squeezable (we also instrumented a little-stapler squeezer and it was less-preferred, without question, to the pliers, by our test users)
2. The aggregate visualization. We discussed the visualization quite a bit, for example, this post describes one idea with fans and fabric and this . One problem that we encountered was the need for more-than-usb power-levels. While we did eventually get this resolved, it was only at the very end of the project, so we used a simple light-based visualizer for our user-testing. The 2nd image above shows both the light-based visualizer and the fan blown pinwheel visualizer.
