Wearable Remote Control (1)

Idea
A wearable remote control. Basic simple functions, like rewind, fast-forward, volume up and down, and play/pause.
The concept plays with the idea that we’re always losing our remote controls, then the best place to have them would be in our bodies.
Project developed for the Dynamic Interfaces Class, in collaboration with Apon Palanuwech and Ayodamola Okunseinde.

Hardware Development
a) 1st Prototype
The project started with a different product in mind. We wanted to build a keyboard embedded in our pants. Maybe using Engelbart’s Chorded Keyboard to reduce the number of keys needed.
We began by experimenting with conductive ink and paper.

That didn’t work out. Maybe because the ink is not that conductive, maybe because it was a complete mess.
But we also started to rethink the concept from an user’s perspective. What device would make sense as a wearable-remote? A five-finger keyboard probably wouldn’t. That’s how we got to the remote control.

b) 2nd Prototype
We started to experiment with a prototype that Ayo has previously developed. It uses aluminum foil and conductive fabric to create a sort of resistive sensor.

We made some tests using conductive fabric too, but it all seemed too unstable and low-conductive.

c) 3rd Prototype
We changed the material to conductive plastic and it worked better. This prototype uses the Arduino Capacitive Sensing Library, and the circuit is mounted pretty much like in the library’s tutorial. However, we put two wires, one in each side of the stripe. By doing so, we could measure an approximate distance from the finger to the wires.04 05

c) 4th Prototype
With the basic functionality solved, we added two more wires to get readings from the two axys (x and y). We also tried to solve some isolation and conductivity problems by using cardboard, cooper tape, conductive plastic and alligator clips.06

Next steps
Software development: serial communication, filter the data.
