For my ICM final, I modified the ‘following a light’ sketch idea to displacing a projected abstract pattern: As a figure moves, the ground shifts. When an individual walks onto the floor, the surrounding sketch alters like this (use your mouse; from openprocessing):
The perspective shifting, illusory nature, and synthesis and articulation of planes of Op Art are influences in creating the projected pattern.
Without activation, the projection is still. Displacement will scrunch or widen shifting lines. While most the paintings are square or tiled, our projection will focus on the outline/line rather than the center (the grid as opposed to the squares).
Questions for ICM class feedback:
- How would I make the movement within the sketch realistic? For the simple sketch that allows the mouse to change the surrounding lines, translate, popMatrix, and pushMatrix are used.
On the Pcomp side, Joshua Clayton and I are using the physical computing/interactive aspect as our final in that class. We tested materials and methods to create a working sensor. Currently, we have a sensor made from wire mesh, and separated with 1/8 foam.
The next sensor will use wider foam strips so the area for closing the circuit will be smaller, as right now it’s very sensitive, and we’re likely to get false positives. Additionally, the plexiglass we’re considering using as the floor material is hard, and distributes its weight evenly across the sensor area. As a result, you have to apply quite a bit of pressure once the sensor is under a tile.
Questions for class feedback:
- These tiles and underlying sensors have to be set up somehow with hidden wiring and Arduino. We’re considering a wooden box with cross bars for support. Thoughts or suggestions?
- Floor material. The floor is simultaneously the projection screen, the media controller, and the actual floor a person would stand on. Since we’re doing a scale model, we’re using our hands as our feet. Plexi looks great, but we’re finding it to require a good deal of pressure to give an ‘on’. Should we be considering softer materials?
