Public - January 2015
BCI or …
MMI – Mind-Machine Interface
DNI – Direct Neural Interface

STI – Synthetic Telepathy Interface
… is anything that can make a
brain communicate DIRECTLY with an

‘Brain-waves’
Different emotional states => Different Waves

EEG/EMG
Electro-Encephalo-Graphy – Brain
Electro-Myo-Graphy – Muscles
Built on the same principles
Catches noise
Needs conductive gel
Enter NeuroSky 2004
Research started 1999. Founded company in
2004
Stanely Yang CEO, Based in San Jose
OEM of sensors and technology
MindWave – 1st low cost consumer EEG
DRY sensors + noise reduction
Standard battery cell + Bluetooth= Wirefree
NeuroSky MindWave
Fundamental Measures
Alpha waves – (8 to 12 Hz) – Meditation
Beta waves – (12 to 30 Hz) – Attention
Meditation and Attention are NOT Opposites*
Wink – has a unique pattern of waves
BCI Moments
1. Mind training
2. Brain-muscle coordination (EEG-EMG)
3. State of mind detection
4. Hands-free, speech-free (medical/general)
5. Gaming/entertainment
1. Mind Training
US Archery Team – Relaxed concentration
Muze by InteraXon
Brain Bot – Rohan Dixit – Own device
Artistic EEG music helmet
2. Brain-Muscle Coordination
