Assistive Technology for Computers

The phrase Assistive Technology is used to describe a number of different kinds of devices that make life easier for those who are mobility challenged. These devices are designed to not only increase an individuals freedom and independence, but also help them preform tasks that they might not otherwise be able to do.

There are a number of well known devices, such as canes and wheelchairs, that fall under the category of Assistive Technology, however as the popularity of computers and the internet increases, more and more companies are developing software to allow an individual to more easily interact with their computer.

Often, devices like wheelchairs are the first thing someone thinks of when Assistive Technology is mentioned, but Assistive Technology for computers fulfills a very important role in the medical industry. Everyday, more and more computer aided devices are designed and implemented to improve the lives of those who have trouble seeing, moving, or hearing.

Assistive Technology Computer Programs are designed to make it easier to use a computer and thereby interact with others. This allows people to stay connected with their family, learn, complete studies, and in general lead a better life.

Voice recognition software is one of the most popular types of Assistive Technology, which is designed to allow a computer to successfully interpret someones spoken commands. This means an individual is able to tell their computer what to do or dictate a letter without ever touching the keyboard.

Speech Recognition software can be a great aid for those who have trouble seeing, but is even more crucial for those who are unable to physically use a traditional keyboard and mouse.

The Brain Computer Interface is another very popular and exciting type of assistive technology. A Brain Computer Interface, which is commonly called a BCI, is designed to allow an individual to control their computer by using their brain.

In many ways, Brain Computer Interfaces are reminiscent of a science fiction movie, but a number of successful Brain Computer Interfaces have been created. BCI's work by analyzing the electrical signals that are sent throughout a brain and interpreting these signals with special sensors. Over time, an individual will be able to send specific signals, which the BCI in turn interprets and responds to. Often, a BCI will include a special hat that is worn over the head, although there are also Brain Computer Interfaces that are implanted into a person's head.

Eye tracking software is also beginning to become popular and allows an person to control a computer by simply moving their eyes. Most eye tracking systems use several digital cameras on either side of a computer monitor. These cameras are able to determine where an individual is looking and whether their eyes are open or shut. This allows an individual to move a mouse or type using their eyes.

On-Screen Keyboards are another more common type of assistive technology that many people are already experienced with. An On-Screen Keyboard provides a virtual keyboard on the user's computer screen. They can then use their mouse to click on the keyboard and type commands.

Magnifying Programs are also very common and are considered a type of assistive technology. A magnifying program provides a virtual magnifying glass for the user to help make images and text on the screen bigger. It is also possible to invert the colors and create a high contrast color scheme for those who are color blind. Most operating systems include an On-screen Keyboard and Magnifying program.
