Sandpaper texture with improved gradient
from smooth to rough
Pipe-cleaners with larger surface area and more
colors to enhance surprise effect
Sanded balsa with staircase texture to match sound
Sponge with increased surface area
Soft synthetic wool with increased surface area
After talking with Angela about my design it came to my attention that there were a few areas that needed developing. The way the user interacts with each surface is crucial in the designs success. In order for the sound to be triggered the user must apply enough pressure to each surface. I solved this by extruding each surface away from the keys of the controller. This created more torque so less pressure needed to be applied to the surface to push down each key. Secondly the surfaces required the user to run their hands along the surface rather than just touch to achieve the full experience. We talked about making the surfaces sloped, the the user would be forced to run there hands along the surface. However in testing the user had to use an uncomfortable wrist/hand position to achieve this. I decided to instead make the surfaces longer. This had a positive effect as most users instinctively wanted to run their hands along the long surface rather than just touch.
