Proposal for Brain Computer Interface.

I enjoy using science, technology and art to inspire and inform my work. I cross numerous disciplines to create my pieces, like ceramics, casting, sculpting, photography, painting, printing, 3d printing, sound design, 3d CAD design, laser cutting and graphic design.

The fablab is an environment for my art process to expand. I would describe myself as part of the maker movement. My passion is researching, designing and creating usable items, instruments, systems that can be used within the art sector but will also cross over as a usable design for clinical innovation.

PROPOSAL:

To create an Interactive Neuro Design, BCI (Brain computer Interface) this is software and hardware that will react and interact in relation to the brain waves.

 A head garment that transmits via brainwaves and frequency patterns, transpose data into visuals or audible sound (voice, or musical instrument, notation) and/ or 3d print, laser cut the brain pattern into 3d sculptures. This work will be clinical innovation, art installation,  sonic art, performance art and sculpture.

EMOTIV are a company that I have been following since 2012 they have designed EPOC which is a BCI (Brain Computer interface) its wireless EEG sensor transmits data. Although after research  I was advised to avoid emotiv. The software is ok, but there’ve been a lot of questions about the design, things like the sensors measuring no where near enough resistance for an effective differential amp circuit (a few khom when you need more like 1M ohm), such that they likely get a lot of their input from scalp muscle contractions and not actual brain activity.

Mind wave mobile by NeuroSky is another source of EEG technology, and can also be used with Arduino. This device only has one EEG electrode on the arm which rests on the forehead.

Open BCI created their first EEG BCI in 2013 they have made improvements to an already great design, it can now read brain, muscle and heart activity. I have pledged via KickStarter and hope to receive the latest version on July 2016. Open Source BCI video  

I have connected the mindwave mobile headset to an app called Visualizer. This app plays your brain pattern. Video of Brain Activity . The headset connects to your ear and forehead.

The brainvisualizer app records the brain activity. Data is collected and converted into:

HIGH GAMMA, HIGH ALPHA, HIGH BETA, DELTA, THETA, LOW GAMMA, LOW ALPHA, LOW BETA

wave form

I intend to use this technique linking mindwave with arduino here

To create your own BCI you will need:

shield ekg/emg £19.95

http://EEG sensors £10 each

Here I have found a opensource that has listed parts, place of purchase, an cost.

Here is a list of software links.

This sketch represents the idea that I use the mindwave mobile and create the interface required for communication via Arduino and Mindwave. For this you will need:

Mindwave headset
Arduino
RF USB dongle
Avago HDSP-4832 10 element LED bar
475 resistors
674 resitors
pcb board
sparkfun level converter
12 v power source.
