Introduction
Brain-computer interface (BCI) is a fast-growing emergent technology, in which researchers aim to build a direct channel between the human brain and the computer.
A Brain Computer Interface (BCI) is a collaboration in which a brain accepts and controls a mechanical device as a natural part of its representation of the body.
Computer-brain interfaces are designed to transmit sensory information from the brain, or stimulate the brain through artificially generated electrical signals.
GENERAL PRINCIPLE BEHIND BCI
COMPONENTS OF A BRAIN COMPUTER INTERFACE
The BCI consists of several components:
The implant device, or chronic multi-electrode array.
The signal recording and processing section.
An external device the subject uses to produce and control motion &
A feedback section to the subject.
COMPONENT OF A BCI (continued)
BCI APPROACHES
EEG BASED BRAIN COMPUTER INTERFACE
TRAINING OF BCI SYSTEM
TWO TYPES OF APPROACH
In the first approach the subject concentrates on a few mental tasks.
In the second approach the user has to learn to self-regulate his or her EEG response.
SOME EXAMPLES
APPLICATIONS
Provide disabled people with communication, environment
control, and movement restoration.
Provide enhanced control of devices such as wheelchairs,
vehicles, or assistance robots for people with disabilities.
Monitor attention in long-distance drivers or aircraft pilots, send
out alert and warning for aircraft pilots.
Confidentiality
DRAWBACKS
The brain is incredibly complex.
The signal is weak and prone to interference.
The equipment is less than portable.
CONCLUSION
A potential therapeutic tool.
BCI is an advancing technology promising paradigm shift in areas like Machine Control, Human Enhancement, Virtual reality and etc. So, it’s potentially high impact technology.
Several potential applications of BCI hold promise for rehabilitation and improving performance, such as treating emotional disorders (for example, depression or anxiety), easing chronic pain, and overcoming movement
disabilities due to stroke.
Will enable us to achieve singularity very soon.
Intense R&D in future to attain intuitive efficiency.
