Emotiv helmet to web. Visualize your Brain waves and share your emotions with the world

About the project

At a weekend long Hackathon @Google Campus, Tel Aviv (http://brainihack.org/) we decided to create a machine that reads brainwaves of users using an Emotiv device, and output those users’ feeling into the web.

A project by @galbracha @bArmageddon @Jishai @daniik @yitzikc

We "accidently" created a by-product that exposes the Emotiv data to the web in a JSON format.

By doing so we allow JavaScript developers to write on top of what we did and create a unique real-time experience.

Demo

The demo is live http://neurobrush.com - the data doesn't get updated, but it gives you the idea and feeling of the project.

Project Structure

Local - data_publisher (Java Code)

Run this one locally. Reads data from Emotiv helmet or Emotiv emulator, sanitize it, encode it, and send it to the server.

Server - neurobrush_web (Django)

Django app that acts as the server endpoint. It exposes 2 methods: collect() and getlatestdata() collect() will receive data from your local computer getlatestdata() will output the latest data in a JSON format. The base.html also contains a live socket that updates when getlatestdata updates.

How to make it run?

Configuration

Locally:

1.Connect a Emotiv helmet, or use EmoCompser (the emulator)

2.Update EmoStateLog.java. set targetURL

Server:

1.Setup a server (We've used Heroku) that runs the django neurobrush_web.

2.Under neurobrush_web->site->templates->collect.py set REDIS_URL

3.Under neurobrush_web->site->templates->getlatestdata.py set REDIS_URL
