Brain-Computer and Brain-Machine Interfaces Applied to the...

Over the years, brain-computer interfaces (BCIs), or brain-machine interfaces (BMIs), have advanced into a technology that can be regularly be applied to the medical field. BCIs have been used for rehabilitative purposes, such as patients suffering from loss of speech and motor functions. Every year, approximately 795,000 people suffer a stroke. Out of these people, 600,000 of these are first attacks and 185,000 are recurrent attacks [9]. Stroke patients often suffer from paralysis and loss of speech. The use of BCIs can be highly beneficial to these patients, as well as to patients suffering from other diseases and traumatic injuries that result in loss of speech and motor function. Besides this, BCIs can also be useful in other areas of the medical field besides rehabilitative purposes. This technology, which was once only seen science-fiction books and movies, is now becoming a realistic approach to treating patients. A BCI allows control of computers with the regulation of the pa tient’s brain activity alone. There are invasive BCIs that are primarily used in animal models where electrodes are implanted into the brain tissue, and noninvasive BCIs that use EEG recordings in humans. Much research has been done on using BCIs for stroke patients who suffer from paralysis and loss of motor function. The goal is to use BCIs to help these patients recover communication and motor function again. Over the years, much research has been conducted on patients who cannot communicateShow MoreRelatedSmart Hci Helping People With Disabilities Essay3711 Words   |  15 Pagesin the human computer interaction era. The central nervous system in the human body that controls the bodily movements and allows us to interact with the computers is referred to as the motor system. However, even with these technological advancements the world is experiencing, the human body is far from safe. Every day, thousands of people are suffering from paralysis; which takes away their abi lity to move and communicate. This paper aims to discuss a new branch in human computer interaction knownRead MoreSensing And Manipulation Through Touch2835 Words   |  12 PagesAbstract: Haptics refers to sensing and manipulation through touch. Haptic Interface helps in exploring part of the environment and achieving tactile identification of objects, positions and orientations. Haptic device gives people a sense of touch with computer generated environments, so that when real/virtual objects are touched, they seem real and tangible. Now days we focused on the involvement of haptics in solving challenging problems in the streams of mechanical design, actuators and realRead MoreBusiness And Organizational Aspects Of Hci1205 Words   |  5 Pages Business and organizational aspects of HCI My research on the business and organizational aspects of Human Computer-Interaction has been incredibly interesting. As an Information Technology professional, I had no idea how many large scale Human Computer-Interaction initiatives were in place. I was really surprised to learn about the different areas HCI researchers were working to improve. We currently live in a monster data generating era. The amount of data that each individual on earth isRead MoreUltrasound Imaging : An Ultrasound Machine1291 Words   |  6 PagesThe photo on the right shows a medical technician using an ultrasound machine to diagnose appendicitis to a patient, without the use of x-rays. The ultrasound imaging technique involves using high frequency sound waves and their echoes. The machine transmits high-frequency sound pulses into the patient’s body using a probe. In the image, the technician presses and moves the probe along the patient’s body. This photo was taken in the St. Louis Ch ildren’s Hospital. A wave is a traveling disturbanceRead MoreARTIFICIAL INTELLIGENCE6331 Words   |  26 Pagesperform a little arithmetic mechanically. Babbage’s analytical engine was the first significant success in the modern era of computing. Computers of the first generation, which were realized following this revolutionary success, were made of thermo-ionic valves. They could perform the so-called ‘number crunching’ operations. The second-generation computers came up shortly after the invention of transistors and were more miniaturized in size. They were mainly used for commercial data processingRead MoreBionic: Artificial Pacemaker and Electronic Noses8677 Words   |  35 PagesBionics is a field, which combines both electronics and biology. In simple terms, when we think about bionics, it is generally more about prosthetic arms or leg enhancement worn outside the body and, to some extend, even implanted sensor devices inside the body, which are essentially enhanced to carry out certain routine tasks. These are essentially life systems that are powered by motors/actuators and sensory arrays. These send neural signals from affected part of the body to the brain, by which individualRead MoreBenefits that Robots Bring to Society2172 Words   |  9 Pages but must also be aware of the numerous difficulties and possible ramifications this new age may bring us. A robot is defined as â€Å"A machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer.† 1 When the average person hears the word â€Å"robot† they often think of a bi-pedal, autonomous, and human-like machine. Although prototypes for these types of robots are already being made, the word robot covers a much larger scope. We are already beginningRead MoreThe Bionic Man And The Morality Of Bioengineering2199 Words   |  9 Pagesâ€Å"the pre-school children were not pretending when they engaged socially and morally with AIBO† (Kahn 122). While the children knew AIBO was not a true, live dog, they still cared for AIBO and feared it like they would a live dog (Kahn 121). As the field of bioengineering develops, new ontological classification of beings have emerged, raising important ethical questions. Soon the difference between â€Å"inanimate† and â€Å"animate† will become indistinguis hable, as illustrated with the case of AIBO. As societyRead MoreComputers in Different Spheres of Lives5456 Words   |  22 PagesComputers in different spheres of lives A computer is an electronic device, which executes software programs. It consists of 2 parts-hardware and software. The computer processes data through input devices like mouse and keyboard. The computer displays output through output devices like color monitor and printer. The size of a computer varies considerably from very small to very big. The speed of computers also has a very large range. Computers have become indispensable in today’s world.
