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
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,..
- ...
Real brainwaves centered current affordable commercial offers are either too simple (Mindset : ONE dry sensor) or required complex setup (Emotiv: several WET sensors).
Commercial ready-to-use BCI-kits
Single EEG sensor headset: NeuroSky Mindset
- http://store-eu.neurosky.com/products/mindset (149 euro)
- BSD license Python SDK that works under linux with bluetooth access: https://github.com/groner/pythinkgear
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.
- 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.
ART
- DialogueS, EEG project
- Mind controlled...
