BCI: Brain Computer Interface
What is BCI?
A computer based system that acquires, analyzes
& translates brain signals into output commands
in real time
The Electric Brain
BCI works due to the way the brain functions.
Neurons in our brains send electric signals when
we think, move, feel, etc. These signals are generated
by differences in electric potential carried by ions.
BCI Input & Output
Using electrodes on the skull, signals can be
acquired and amplified.
The acquired signal will then be interpreted
by a computer program and turned into a command
Definition: the brain is able to adapt in amazing ways
to new circumstances.
Brain would be able to adapt to the new use
of neurons and could treat the new connections
as part of the brain.
BCI is able to understand the users intent,
this leads to less errors.
Reduced lag, this is due to BCI being able to pick
up signals before the user is aware of the decision.
Amazing potential for those who suffer motor
Could provide a more natural
feeling artificial limb.
Allow user to control their environment such
as their television or lights in their home.
Allow user to control BCI wheelchairs with only their mind.
Train the brain to relearn how to control
BCI could provide feedback to the teacher about
whether the students understood the lesson.
BCI could help combat depression and
help control stress.
New games are being developed using
BCI as the main controller
BrainBall is a good example
Biometric signals are unique to the person.
Difficult to detect or pickup signals by third party observers
Since Signals are unique, eliminates the possibility for
Problems it can solve
Loss of limb control
Difficulties controlling computer
Help heal diseases like ALS, Cerebral Palsy
