Leggings

Keyboard control using custom wearable flex sensor (in the leggings).

This project was originally made to control the slides of this presentation:

What?

The system uses:

• a stretch sensor connected to a WiFi-MCU board
• a program that analyses the received data to emulate key controls accordingly.

Sensor

The full wearable sensor is documented here:

You can also create a simpler custom sensor circuit using suggestions documented here:

Board

The WiFi-MCU board used here is an X-OSC:

Connecting to this board in WiFi can be tricky for some, check at their documentation.

How?

To use this program, you need processing, it can be downloaded here:

http://processing.org

...and once you're connected to the X-OSC board, run the code in this file:

Alternative

If a wireless control breaks, it's always good to have a connected version. The teensy code in the following folder does exactly that:
