BRAIN MACHINE INTERFACE
INTRODUCTION
Neural Interface- New means of communication
Control of applications by thoughts only
BMI - - Read electrical signals of brain
activity
- - Translate them into digital form
- - Convert into actions of some
kind
Provide assistance to people with inabilities
DIFFERENT TYPES
Invasive -- Implanted directly into the grey
matter
-- Produce the highest quality signals
Partially Invasive
-- Uses Electrocorticography
-- Implanted inside skull but rests outside
the brain
-- Lower technical difficulty
-- Lower clinical risk
-- Probably superior
long-term stability
Non Invasive
-- Uses Electroencephalography
-- Low set-up cost
-- Ease of use
-- Portability
-- Susceptibility
to noise
TECHNOLOGY
Bioelectrical activity of nerves and muscles
Signals generated on brain surface
-- monitored and analyzed
Imagine doing something
-- Small signals generate
from different areas
of the brain
Control the brain functions
-- artificially producing these signals and
sending them to respective parts
BRAIN WAVES
ELECTRODE PLACEMENTS
The sensors are labelled
by proximity over a region
of the brain
Number for exact
position
-- Odd numbers-Left
-- Even numbers-Right
DESCRIPTION
The main components of BMI:
The implant device, or chronic multi-electrode array
The signal recording and processing section
An external device which the subject uses to produce and control motion
A feedback section to the subject.
ADVANTAGES
Means of communication for people with disabilities
Provides better living, more features, more advancement in technologies etc.
Linking people via chip implants to super intelligent machines
Allow for computer intelligence to be hooked more directly into the brain
Gradual co-evolution with computers.
CHALLENGES
Connecting to the nervous system could lead to permanent brain damage
In the networked brain condition -- Human mind exposed to encroachment
Virus attacks may occur to brain causing ill effects
APPLICATIONS
Auditory and visual prosthesis
Functional-neuromuscular stimulation (FNS)
Prosthetic limb control
In effective construction of unmanned systems, in space missions, defense areas etc
Communication over internet can be modified.
PRESENT SCENARIO
FUTURE SCOPE
Linking people via chip implants to super intelligent machines seems to be a natural progression –creating in effect, super humans.
Human-Machine and Machine-Human communication
Humanoids????
CONCLUSION
BMI -- the ability to give people back their vision and hearing
People with disabilities -- New and normal life
Change the way a person looks at the world
Someday these devices -- more common than cellphones
