A brain computer interface allows signals from the brain to direct external devices like controlling a cursor. There are invasive BCIs that help paralyzed people move prosthetics and non-invasive BCIs that are safer options. BCIs allow controlling video games and transmitting images to blind people. While BCIs help people, the research is still early and ethical issues may limit development.

Brain-computer interfaces (BCIs) aim to detect intentions from the brain and use them to control assistive technology. The most common detection method is electroencephalography (EEG) which measures electrical signals on the scalp. Interpretation of EEG signals has allowed some to control wheelchairs or spell words at rates of 2-36 words per hour. Commercial BCIs are emerging but they remain slow, unreliable, and primarily demonstrated for people with locked-in syndrome. However, progress continues through improved interpretation methods, lower costs, and demonstration of prosthetic and communication applications, suggesting BCIs may soon be suitable options for some users of assistive technology.human computer interface

Social research refers to research conducted by social scientists using either quantitative or qualitative methods. Quantitative methods use statistical analysis to make general claims while qualitative methods emphasize understanding social phenomena through observation and communication to stress contextual accuracy. Research aims to gain new knowledge through a systematic and discovery-based process of moving from the known to unknown. The main purposes of research are to explore phenomena, describe individuals or groups, determine relationships between variables, and test hypotheses. Social research is defined as a scientific method of studying social life to extend, modify or verify knowledge to develop social theories or inform practice. Ethics in social research focus on voluntary participation, avoiding harm, integrity, and protecting privacy, anonymity and confidentiality.

2) The objective of BCI is to develop a fast and reliable connection between the brain of a severely disabled person and a personal computer to allow communication and control through thought alone.
3) BCI research has progressed from animal experiments to human trials, allowing paralyzed patients to control devices and communicate just by thinking. However, widespread adoption is still limited by challenges with sensor accuracy, information transfer rates, and system costs. HUMAN BRAIN INTERFACE

This seminar presentation summarizes the BrainGate system, a brain-computer interface that allows individuals with paralysis to control external devices with their thoughts. The BrainGate system works by implanting an array of electrodes on the motor cortex that detect brain signals, which are then translated by external processors into commands to control a computer cursor or prosthetic devices. Some key advantages are that it allows quadriplegic individuals to control devices like computers, phones, wheelchairs. However, it is also an expensive and risky surgery, and has limitations in speed and wireless capabilities currently. Future developments aim to create smaller, wireless versions with improved control capabilities.Brain computer interface

The Braingate system allows a paralyzed man to control a computer using his thoughts by monitoring his brain activity through a brain implant. Developed in 2003 by Cyberkinetics and Brown University, Braingate consists of a chip implanted on the motor cortex that detects neural signals which are transmitted to an external processor and translated to move a computer cursor. While offering paralyzed individuals control of devices, Braingate is expensive, requires risky brain surgery, and has limited information transfer rates, though it provides hope for independent living.Brain computer interface.pptx

BrainGate is a neuroprosthetic device that uses a sensor implanted in the brain to monitor brain activity and convert those signals into computer commands. It was developed in 2003 to help people who have lost control of limbs, like those with ALS or spinal cord injuries, regain independence. The implant consists of a microelectrode array and connector that detects neural signals in the motor cortex when a user thinks of moving and translates that into mouse cursor movements on a computer screen.Brain¨Ccomputer Interface

The document discusses the history and current state of brain-computer interface (BCI) technology. It describes how early work in the 1970s developed algorithms to reconstruct movements from motor cortex neurons. Researchers then built the first intracortical BCI by implanting electrodes into monkeys. Current BCI approaches can be invasive, partially invasive, or non-invasive. Invasive BCIs have electrodes inserted directly into the brain but provide the highest quality signals. Potential applications of BCI include helping disabled individuals, enhancing games, and developing medical devices like a bionic eye. However, challenges remain in improving signal quality and preventing tissue scarring from invasive electrodes.Human computer interaction

Brain-computer interfaces (BCI) allow direct communication between the brain and external devices by detecting brain activity through electrodes implanted in the brain or placed on the scalp. The goal of BCI research is to provide paralyzed or motor-impaired patients a way to communicate and control devices simply through thought. Early experiments implanted BCI devices in rats and monkeys' brains to allow them to control robotic limbs. The first human testing of a BCI device occurred in 2004, allowing a paralyzed man to control a computer cursor and play simple games using only his thoughts over several months. BCI systems work by capturing brain signals, processing them to recognize patterns, and using those patterns to control assistive technology.Brain Gate
