For HackPrinceton 2013, I made DDR Gloves!
This was a fun one. I wanted to make a mat-less version of DDR. Originally we were planning on using Wiimotes, but that didn’t work out; so instead we made a pattycake version using an Arduino Uno, a bunch of tinfoil, and some gloves. The tinfoil acts as a touch sensor. One player wears the gloves, the other player just uses their hands. And then we used StepMania to play DDR! It’s a bit like pattycake.
It was a good time. My teammates for this hack were Vincent Castenada, Kanika Pasricha, and Jan Cash.
