BRAIN-COMPUTER
INTERFACE (BCI)
Public - January 2015

2. BCI or …
 MMI – Mind-Machine Interface
 DNI – Direct Neural Interface
 BMI – Brain-Machine Interface
 STI – Synthetic Telepathy Interface
… is anything that can make a
brain communicate DIRECTLY with an
external device/computer

3. How the Brain Communicates
 Human Brain =10 B interconnected neurons

4. ‘Brain-waves’
 Different emotional states => Different Waves

5. EEG/EMG
 Electro-Encephalo-Graphy – Brain
 Electro-Myo-Graphy – Muscles
 Built on the same principles
 Catches noise
 Needs conductive gel

6. 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

 Standard battery cell + Bluetooth= Wirefree

7. NeuroSky MindWave

8. 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
