/tmp/bci (aka Neurohack)

(Wiki updates in progress)
Project involving hardware and software in 3 different major fields : Science / Computer Interface / Art Currently 3 hardware and 2 software main directions are followed.

HARDWARE

Commercial ready-to-use BCI-kits

Real brainwaves centered current affordable commercial offers are either too simple (Mindset : ONE dry sensor) or required complex setup (Emotiv: several WET sensors).

NeuroSky Mindset

Single EEG dry sensor headset with audio
Ability to sample at 512Hz and access the raw signal or filtered FFT transform every second (waves: alpha, beta, delta, ...)
BSD license Python SDK that works under linux with serial access mapped to the bluetooth device: https://github.com/groner/pythinkgear
Software for OSX and windows also available by headset manufacturer : Neurosky

Emotiv

TODO: describe me!

DIY EEG headset

2 OpenEEG sets were built (2 wet electrodes each)
Continuous raw data feed only that must be filtered and analyzed.

DIY Near Infra Red Spectroscopy headset

Designing a new acquisition device (efficient, easy to wear, affordable) using Near Infra Red Spectroscopy
Prelimanary tests were done with a light fiber and spectrometer
Joint developement with Editions Volumique

SOFTWARE

Bainwaves to music, lights, sounds,...

The current allinone homebrewed software is made in Rebol and called "Jackson". Several versions have been created for dedicated purposes, like jprocessing or jLIVE, a sequencer style live tool available from 1 to zillion brains, for art performance, cooperative "construction" (graphics, sound, DMX light control, command,...). The Rebol option was chosen for dead simple portability and to interface seamlessly local and Internet connexions.
Currently supported hardware is the Mindset.

Brainwave sounds

Made in Pure Data

WHAT NEXT ?

Improve OpenEEG solution by signal analysis
Improve control by implementing Machine Learning
Develop artistic collaboration especially in Music composition and wide public use

SCIENCE

Neurosciences : dedicated software for brain functionnal imaging : MRI, near IR, EEG with machine learning
Large sets of brain generated data available in CSV file format. (40 hours)
For more information on machine learning see the subproject page: /tmp/bci/machine-learning

Current steps are : designing experimental tests and results statistic analysis to stronger assess hardware reliability.

ART

Neurohack, as Digital arts - music / video live rendering, human performance of the brain activity - has been done in different venues :

DialogueS, EEG project on December 17 2010.
Fete01 on May 7 2011 for Labomedia Orleans.
MindProcessing for Macval (Museum of contemporary art de Vitry/seine) on May 22 2011.
Workshops at Macval on July 3 2011.

BRAIN COMPUTER INTERFACE APPLICATIONS

Computer, robots,... command.
Help disable people.
BYOU : Bring Your Own Use : the geekier, the better !
