Wearable Remote Control (2)

Idea
A wearable remote control.
Project developed for the Dynamic Interfaces Class, in collaboration with Apon Palanuwech and Ayodamola Okunseinde.

Software Development
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
After that, we translated the processing sketch to javascript and changed the functions to control a video on the browser.

Hardware Development
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…

…and the on a sock:10

Though it looked great as a super-like thing, the plastic collapsed and became very low conductive:

Hardware Development
b) 6th Prototype

A much simpler and more stable solution was achieved when we simply put the plastic on an E.V.A. wrist band:
