History – Discovering the Basics
1924: Hans Berger discovers the EEG
Analyses the interrelation of EEG and brain diseases
1970: First developments to use brain waves as input
ARPA has vision of enhanced human
First step in the right direction
Reading the brain…
Direct Neural Contact
Most accurate method
Highly invasive
Not possible with current technologies
Perhaps possible in future with e.g. nanobots
Electroencephalogy
(EEG)
Measures electical activity in brain
Non-invasive
Susceptible to noise
Easy to use + low cost + portable
Most commonly used device in BCIs
