a) 1st Prototype
After building a relatively stable device to measure conductivity along 2 axys (see previous post), we started working on the software. Though our purpose was to build a simple remote control, we started to test with a sort of trackpad — big mistake, maybe?
For this prototype, we used processing and serial communication.
We first tried to assign an absolute position to the ball, based on the finger position on the trackpad. That proved to be impossible, because people’s charge on the pad changed a lot.
So we made the charge give the ball a direction, like in a joystick — the direction from the pad’s center is translated as a new direction to the ball.
b) 2nd Prototype
a) 5th (?) Prototype
Meanwhile, we replicated the hardware circuit in a non-rigid device, to make it wearable. We sewed the conductive plastic on felt…
