Meta project involving hardware and software in 3 different major fields : Science / Computer Interface / Art
The current allinone homebrewed software is made in Rebol and called "Jackson". A specific version "Jackson LIVE" is a sequencer style live tool available from 1 to zillion brains, for art performance, cooperative "construction" (graphics, sound, command,...). The Rebol option was chosen for dead simple portability and to interface seamlessly local and Internet connexions.
Currently supported hardware is the Mindset.
What's new ?
- Inputs now accepts 2 iphone apps : ITM midilab and Isensor
- Output now support OSC messaging (OS X only), so can control MIDI, Max/msp, PureData, TouchOSC...
HARDWARE
Commercial ready-to-use BCI-kits
NeuroSky Mindset
- Single EEG dry sensor headset with audio
- Ability to sample at 512Hz and access the raw signal or FFT transform (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 BCI headset
- Designing new acquisition devices (efficient, easy to wear, affordable) : Near Infra Red, EEG, Magnetometers, MRI compatible,...
- Designing signal analyzing electronic boards : FFT, FPGA, statistical analysis using machine learning algorithms...
- ...
Real brainwaves centered current affordable commercial offers are either too simple (Mindset : ONE dry sensor) or required complex setup (Emotiv: several WET sensors).
BRAIN COMPUTER INTERFACE APPLICATIONS
- Computer, robots,... command.
- Help disable people.
- BYOU : Bring Your Own Use : the geekier, the better !
Goals : a reliable ON/OFF "button" and a scale model (1...10) by cognitive task and interfacing with real world (TCP connexion,...).
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
- Digital arts: music / video live rendering of the brain activity
- DialogueS, EEG project
- Mind controlled...
