BRAIN COMPUTER INTERFACE Tejaswi Palacharla University of Houston ABSTRACT INTRODUCTION What is a Brain Computer Interface? Brain Computer Interface (BCI) is a communication channel between a brain and the computer. The BCI system transforms specific ‘thoughts’, into control signals. These are then converted to a computer readable form where the output is shown on the computer. This computer follows the instructions or thoughts given by the brain when a patient mentally visualizes the cursor reaching the target. The electrode is implanted in the human brain and the brain activity is interpreted by computer software. Then the computer software displays the activity on the monitored screen. This technology is mostly used for people with disabilities. The reason why a BCI works is all because of the way our brain functions. Our brain is filled with neurons. The neurons are at work when we move, think, feel or remember something. The work is completed by small electrical signals that zip from neuron to neuron as fast as 250mph. Now scientists can detect the signals, interpret them and make them to direct a device. Electroencephalography (EEG) is a method used in measuring the electrical activity of the brain. A few examples of Brain Computer Interface for the disabled people are †¢ â€Å"Bionic device is used for the people to restore a sense of vision to people with retinitis pigmentosa and age related macular degeneration.†( Bionic eye Australia,Show MoreRelatedCommunication Technology Research Project : How It Works, And Its Application919 Words   |  4 Pagescouldn’t believe all the different ways it could be used for all different types of people and the lengths it could reach. The technology that I decided to write my paper on is called Brain-Computer Interfaces (BCI). I will discuss what exactly BCI is, how it works, and its application in today’s world. Brain-computer interface is a technology that has been around for a while, however the technology has really taken off in recent years. The thing that makes this technology so dynamic is the fact that itRead MoreNeural Technology : Brain Computer Interface934 Words   |  4 Pagestechnology is a field of engineering that specializes in taking information that is present in the brain and translating it to a medium that can be understood by a wide range of people. One of the ways this is done is with systems that take information directly from the brain and enable control over a computerized system. These are referred to as brain computer interfaces, also known as BCIs.

This amazing technology will not only revamp military applications, but most importantly help the medical community substantially. It brings the possibility of sound to the deaf, sight to the blind and movement to the physically challenged. However, with all great ideas there is a downside, there are many technical and ethical issues that people are not willing to risk.

This knowledge is recognized by several monitors, such as BCI, Brain-Machine Interface (BMI), neuro-brain transmission and Direct Brain Interface (DBI).

As a result affected individuals become â€Å"locked in† and unable to communicate. These patients can benefit greatly from the use of a brain computer interface (BCI)(Birbaumer, 2006; Coyle, Ward, Markham, McDarby, 2004). BCI can help individuals communicate without relying on muscular control, which is critical for clinical populations of neuromuscular disease patients, such ALS (Wolpaw, 2002)Read MoreThe First Task Of Either A Writer Or A Critical Book Reviewer1735 Words   |  7 PagesThe first task of either a writer or a critical book reviewer is to imagine the audience for whom the work is intended. For us at Interface, that is those interested in the impact of the Internet. Some works, however, like the one under review, defy easy classification, perhaps because they fail to target an appropriate audience or to speak consistently to it. This might be a sign of a weak book, not actually suitable for anybody; too much of its content may miss the mark. Both a reader’s time andRead MoreDevelopment Of Brain Interfacing Devices1426 Words   |  6 Pagesdevelopment of brain interfacing devices. Brain interfacing has been used with computers, animals, and other human beings. Harvard and researchers Pais-Vieira and Miguel were both successful in creating a brain interfacing device that could control the movements of lab rates. Scientist have managed to create devices that can manipulate the thoughts and movements of other human beings. Brain interfacing is when scientist use computers to communicate and manipulate other living things. One common brain interfacingRead MoreNeural Prosthetics And Its Effects1741 Words   |  7 Pagesolder we begin to lose a plethora of our abilities; through old age, an injury, or whatever the case may be, we all slowly deteriorate. With modern science we are now able to regain some of what we had lost or have never hard, through neural prosthetics.
