A REVIEW ON BRAIN COMPUTER INTERFACE

A brain-computer interface (BCI) establishes a link between the human brain and the external devices. BCIs measure the brain activity for fetching the user’s intent and subsequently provide the control signals to the supporting hardware. This technology has varied uses ranging from assistive devices for disabled individuals to advanced simulator control. The main use of BCI is as an assistive technology for individuals suffering from loss of motor control caused by spinal cord injury, amyotrophic lateral sclerosis or any other possible incidence. BCIs take advantage of the brain’s electrochemical signals. There are billions of neurons in human brain with trillions of interconnections known as synapses. These devices also make use of neuroplasticity which is the brain’s ability to change physically and functionally over time. Author has discussed the basics of BCI in this paper and has presented details regarding brain waves, control centers of various organs in brain, invasive and non-invasive sensors. This paper also presents a summary of the research work going on in this area.

A large number of persons approximately the world knowledge the unwell belongings of beating of action, rendering them reliant on others to perform even the most essential errands. In any case, that could change, due to the most recent accomplishments in the Brain-Computer Interface (BCI), which could enable them to recapture a segment of their lost freedom. Indeed, even ordinary people may likewise have the capacity to use Brain Chip Technology to improve their association with the advanced world-if they will get the embed. The term 'Mind Computer Interface' alludes to the immediate connection between a solid cerebrum and a PC. Serious endeavors and research in this BCI field over the previous decade have as of late brought about a human BCI implantation, which is incredible news for every one of us, particularly for the individuals who have been surrendered to spending their lives in wheel seats. This Brain Chip Technology is a stage for the advancement of an extensive variety of other helping gadgets. This paper concentrates on the Brain Chip Technology which encourages quadriplegic individuals to do things like checking email, turning the TV, lights on or off with simply their contemplations. Likewise, the meaning of Brain-Computer Interface, the essential objective of planning Brain entryway, the fundamental components of Brain Gate, the exploration work led on it at various Universities and some inadequacies of Brain Gate were additionally introduced. 1 In simulation and recording, the description and screenshot of each substitute in the model were given.

A Study Of Brain Computer Interface System

2013

Advances in cognitive neuroscience and brain imaging technologies have started to provide us with the ability to interface directly with human brain. Brain Computer Interface (BCI) is a system that acquires and analyzes neural signals with the aim of creating a communication channel directly between the brain and the external device or computer. The major goal of BCI research is to develop a system that allows people severely affected by motor disorders to communicate with other persons and helps to interact with the external environment. Achievement of greater speed and accuracy of the BCI system depends on improvements in signal processing, translation algorithms, and user training. These improvements depend on increased interdisciplinary cooperation between neuroscientists, engineers, computer programmers, psychologists, and rehabilitation specialists. The objective of this paper is to provide insight into the various aspects of BCI which will help the beginner in this field to understand the basics of BCI.

A study on recent trends in the field of Brain Computer Interface (BCI

Since 1969, many scientist has started to know about Brain Computer interface technology as a new platform for those with neuromuscular disorder that confine them from using this common rising methods. It gives a direct communication between the brain and a computer or any external devices. Brain Computer Interface offers a huge scope by strengthening or by decreasing human working capability. It has many applications in various fields such as robotics, gaming, neuroscience etc. A brain-computer interface, also known as a brain-machine interface (BMI).It is a direct communication path between the brain's electrical activity and an external device. It can occur through many stages, firstly the user encodes his or her instructions in the electrophysiological input which is provided to BCI then BCI recognize that command and express it in device control. BCI can do all the task properly when Signal acquisition, translation algorithm and user training are fully updated. This device can help millions of physically disabled people to spend their life as regular person.

A Complete Review of Brain Computer Interface

Zenodo (CERN European Organization for Nuclear Research), 2022

The technology of Brain Computer Interface (BCI) is a rapidly growing research field with vast applications. BCI acts as a bridge between a human brain and the machine-like computer. The main purpose of BCI system is to enable the people with disability to interact with outside world. The electrical signals captured from the brain are processed to remove the noise and artifacts. The features of the processed signal are extracted, classified and later translated into the device commands in order to execute the intent of the user. This paper furnishes the basics of BCI, different ways of signal acquisition, overview of the BCI system, its applications and challenges.

Review Paper on Brain-Computer interface and recent trends

International Journal of Modern Trends in Engineering and Research, 2015

Although the development in computer hardware and software has been enormous in recent decades, but the development in Human-computer interface (HCI) has been very slow but discontinuous. From punch cards, text console, mouse to recently introduced gesture and voice controls the development is enormous, the recent addition to this is Brain computer interface (BCI). BCI makes uses of changes in brain and Electrical activity of brain to certain actions/thought processes and uses algorithms to interpret the intention of the user, and reports the same to computer. This paper focuses to review this area of HCI and demystify the techniques and concepts used and also give a short report on recent development and research on the same .This technique of BCI not only would be helpful for disabled to gain new strength but also would change the way we interact with machine...FOREVER.
