BRAIN COMPUTER INTERFACE
The ability to interact directly with the human brain came about due to advances in cognitive neuroscience and brain imaging technologies. This is all made possible with the use of sensors that can monitor some of the physical processes which take place within the brain and correspond with certain forms of thought. Once such technology which have arisen due to these advances is the brain computer interface (BCI). This is also referred to as brainwave computing, thought controlled computing, mind controlled computing or thought interpreting computer software and programming, (Shah, 2014).
It functions as communication systems which do not depend on the normal outputs pathway of the brain which consists of peripheral nerves and muscles. However, the user manipulates their brain activities without using any form of motor movements to produce signals. These signals are used to control the computers or communication devices. The development of BCI was driven by a societal recognition to provide resources for needs of individuals with physical disabilities, (Tan & Nijholt, 2010). This technology bypasses any form of touch or voice where the programmes or computers are instructed by thoughts from the user.
There are two different categories of brain imaging technologies: invasive technologies where sensors are implanted directly on or in the brain and the non-invasive technologies which measure the activity of the brain using sensors. The invasive method provide a high temporal and spatial resolution, they only cover very small sections of the brain. This method requires a surgical procedure to be carried out, which could lead to medical complications as the body adapts to or does not adapt to the implants. Once...

The Human Body as a Computer Interface Essays

- Interfaces take places into our lives in the form of the various devices, analog or digital, with whom we normally establish some kind of interaction. This means that the interfaces are "tools" extenders for our bodies, such as computers, cell phones, elevators, etc. The concept of interface is applicable to any situation or process where the exchange or transfer of information takes place. Some of the ways of thinking to the interface might be like “the area or place of interaction between two different systems not necessarily a technological system”....   [tags: Medical Research]

Interactions with a Post WIMP Interface Essay

- Many people have iPads, smart phones, and PDAs. The challenge to create an effective interface can be quite difficult. These small devices contain powerful technologies that make the lives of the user easy by allowing instant access to the Internet. With this access, almost any sort of information is available. However, without the use of the keyboard or computer mouse, the WIMP interface (Windows, Icons, Menus, and Pointers) becomes useless. Fortunately, the technological world has adapted to these changes by creating new interfaces....   [tags: Technology ]
