As the power of modern computer grows alongside our understanding of the human brain, we move even closer to making some pretty spectacular science fiction into reality. Imagine transmitting signals directly to someone's brain that would allow them to see, hear or feel specific sensory inputs (in short we can make any blind person watch, deaf person hear). Consider the potential to manipulate computers or machinery with nothing more than a thought. It isn't about convenience for severely disabled people; development of a brain-computer interface (BCI) could be the most important technological breakthrough in decades. In this seminar and presentation, we'll learn all about how BCIs work, their limitations and where they could be headed in the future. One of the most exciting areas of BCI research is the development of devices that can be controlled by thoughts. Some of the applications of this technology may seem frivolous, such as the ability to control a video game by thought. If you think a remote control is convenient, imagine changing channels with your mind. However, there's a bigger picture, devices that would allow severely disabled people to function independently. For a quadriplegic, something as basic as controlling a computer cursor via mental commands would represent a revolutionary improvement in quality of life.

There are other means of reading brain activity than direct neural contact via pins. The first and most common is electroencephalography (EEG) where electrodes are placed against the scalp are used to pick up brain signals. However, this approach is not nearly as accurate as direct neural contact and can only pickup blurry, weak readings. The other, much newer, and much more accurate non-invasive technology is magnetoencephalography (MEG) but is also more equipment intensive. Using MEG requires a room filled with super-conducting magnets and giant super-cooling helium tanks surrounded by shielded walls. This technology, while providing the speed and accuracy needed for a successful non-invasive BMI, will require significant improvement of technology in order to be realistic for everday use.

brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface (BMI), is a direct communication pathway between the brain and an external device . BCIs usually connect the brain (or nervous system) with a computer system
there is are some more practical explanation you can read from this pages

brain Computer Interface


.pptx   Brain Computer Interface.pptx (Size: 2.09 MB / Downloads: 125)


INTRODUCTION


Human brain, the most valuable creation of
God. The man is called intelligent because of the brain. But we loss the knowledge of a brain when the body is destroyed after the death .

“BLUE BRAIN”- The name of the world’s first virtual brain. That means a machine that
can function as human brain.

Is it really possible to create a human brain?



WHAT IS VIRTUAL BRAIN


A machine that can function as brain
It can take decision.
It can think.
It can response.
It can keep things in memory.



WHY WE NEED VIRTUAL BRAIN


To upload contents of the natural brain into it .

To keep the intelligence , knowledge and skill of any person for ever .

To remember things without any effort .



Sensory Input :-

Receiving input such as sound ,image, etc
through sensory cell .

Interpretation:-

Interpretation of the received input by the brain by
defining states of neurons in the brain.

Motor Output:-

Receiving of electric responses from the brain to
perform any action .

brain Computer Interface

Introduction
Research on BCIs began in the 1970s at the University of California Los Angeles.
A Direct Brain-Computer Interface would add a new dimension to Man-Machine interaction.
BCI is a Direct Communication Pathway between a Human/animal brain and an External device.
BCI
Brain Computer interface (BCI) is a communication system that recognize User's command from brainwaves and reacts according to them.
BCI refers to the direct interaction between a healthy brain and a computer. It doesn’t depend on peripheral nerves and muscles.
EEG
Electroencephalography (EEG) is the recording of electrical activity along the scalp.
EEG measures voltage fluctuations resulting from ionic current flows within the neurons of
the brain.

BCI TYPES

1. Invasive
a. Involves attaching electrodes directly to the brain tissue.
b. The patient’s brain gradually adapts its signals to be sent through the electrodes.
2. Non-Invasive
a. Involves putting electrodes on the scalp of the patient, and taking readings.

BCI ELEMENTS

The input, measuring the activity from the human brain.
The signal pre-processing, the first step of acquiring usable signals by amplification, applying filters and reducing noise and artifacts of the input signals.
The translation Algorithm, this step compromises feature extraction which extracts the most valuable signals from the processed input.
The output, from the future extraction is used as a control signal for various applications.

BCI APPLICATIONS
Some of the BCI applications are…..
1. Error and conflict perception.
2. Working memory encoding.
3. Rapid visual recognition

FUTURE WORKS
Brain Computer Interfaces
◦ Allow with muscle controls to communicate and physical devices.
◦ High Precision (can be used reliably_).
◦ Requires somewhat invasive sensors.
◦ Requires extensive training (poor generalization).

CONCLUSION
BCI is a method of communication based on voluntary neural activity generated by the brain.
BCI can be recorded using Invasive or Noninvasive techniques.

WHAT IS BCI?


BCIs read electrical signals or other manifestations of brain activity and translate them into a digital form that computers can understand, process, and convert into actions of some kind, such as moving a cursor or turning on a TV.

BCI can help people with inabilities to control computers, wheelchairs, televisions, or other devices with brain activity.


MAJOR COMPONENTS OF BCI


Ways of measuring neural signals from the human brain

Methods and algorithms for decoding brain states/intentions from these signals
Methodology and algorithms for mapping the decoded brain activity to intended behavior or action


TYPES OF BCIs


Invasive techniques, which implant electrodes directly onto a patient’s brain
Electrode implants
Chip implants

Noninvasive techniques, in which medical scanning devices or sensors mounted on caps or headbands read brain signals
Output: EEG, MEG, fMRI


WHY BCI?


BCI is a new neuroscience paradigm that might help us better understand how the human brain works

BCI research allows us to develop a new class of bioengineering control devices and robots

BCI hold promise for rehabilitation and improving performance
BCI can expand possibilities for advanced human computer interfaces (HCIs)


WHAT IS AN EEG?


An electroencephalogram is a measure of the brain's voltage fluctuations as detected from scalp electrodes.

It is an approximation of the cumulative electrical activity of neurons.

EEG measures the electrical activity of the brain with multiple electrodes placed on the scalp

It is portable and relative inexpensive that is why most noninvasive BCIs are presently based on EEG.
