I produced four working tiles for the final presentation of my Dance Floor MPC project on December 10. Because I set up the sensors as analog inputs, I was able to detect varying pressure and program the device to support accents in the sequencer. Stepping on the tiles with greater force provides feedback with a different LED color:
During the actual presentation, I taped the tiles to the foam tile base to keep them in place. By this point, I had not yet fabricated the floor console I had designed, so I kept the microcontroller and breadboard in a cardboard box next to the tiles and simply placed the transport LED strip in front of them.
Here's a screen recording of the sequencer web interface which I showed during the presentation (not the exact performance from my demo, but it reflects the state of the code at the time):
I received some good interaction design feedback during the presentation critique which pushed me towards making the device feel more like a game (akin to DDR) rather than framing it as a groove dancing experience; I was forced to face the fact that it's pretty hard to get a groove going on the "Dance Floor MPC" and produce a nice rhythm at the same time (rather, you can dance to the beat you made after using the sequencing features).
