The research paper Computer Science Seminar Topics Brain Computer Interface begins by describing the size of human brain which is of the size of a deflated volley ball and weighs around 3 pounds. The research paper suggests that a Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer. The 100 billion neurons communicate via minute electrochemical impulses, shifting patterns sparking like fireflies on a summer evening, that produce movement, expression, words.
Approach: The research paper describes how the process is achieved. It says that the Invasive BCIs are implanted directly into the grey matter of the brain during neurosurgery. As they rest in the grey matter, invasive devices produce the highest quality signals of BCI devices but are prone to scar-tissue build-up, causing the signal to become weaker or even lost as the body reacts to a foreign object in the brain. The paper says that the easiest and least invasive method is a set of electrodes — a device known as an electroencephalograph (EEG) — attached to the scalp. The electrodes can read brain signals.
Potential Users of BCI Systems
The research paper segregates the potential users of BCI systems as
1. Individuals who are truly unlocked.
2. Individuals who have a very limited capacity for control, e.g., useful eye movement.
3. Individuals who retain substantial neuromuscular control.
The research Paper posits the recent breakthrough in BCI saying that Advanced Telecommunications Research Institute International (ATR) and Honda Research Institute Japan Co., Ltd. have jointly developed base technology for a new BMI (brain machine interface) to operate robots based on the human brain’s activity patterns.
Scope of BCIs: The paper suggests that 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.
The research article concludes by quoting various possible advantages of Brain Computer Interface (BCI). It says that there are many useful applications of brain computer interface. It can be very helpful for people with moving disabilities as human – machine interface. But it can be also used for control of human body muscles. There are also many possibilities of BCIs in the military domain.
