/tmp/bci (aka Neurohack)
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
Jackson : Hub for brainwaves redirected to music, lights, sounds, Internet,...
The 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.
For more about Jackson : /tmp/bci/jackson.
Brainwave sounds
OpenEEG systems with Pure Data software.
TCPOSC
Rebol has no OSC implementation so I wrote a tcp to OSC relay in python.
WHAT WE DO
SCIENCE
- Neurosciences : dedicated software for brain functionnal imaging : near infra red spectroscopy and EEG with machine learning.
- Neurosciences : ability to design experiences with a built in paradigm manager with speech synthesis.
- For more information on machine learning see the subproject page: /tmp/bci/machine-learning.
- Large sets of brain generated data available in CSV file format. (40 hours).
Current steps are : designing experimental tests and results statistic analysis to stronger assess hardware reliability.
For more references (bibliography) : see the /tmp/bci/starterkit.
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 !
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.
- Continue bootstrapping people that need some experience in our knowledge area.
The repository for tmpbci software is tmpbci on github
