Support products

Many people with disabilities need to use support products or technology that act as intermediaries between them and ICT. These support methods and tools enable users with special needs to carry out certain tasks that would otherwise be impossible or extremely difficult for them in a number of situations. This means that people with some kind of disability can do the same things as someone with no kind of impairment at all. You can also find the terms technical aids and assistance technology to describe support products, although the latter is more appropriate.

The most common support products can be arranged into three broad groups: screen readers, screen magnifiers and voice recognition.

Screen readers

Screen readers are support products used by people with significant visual disabilities (blind people or people with severely impaired vision). They are software programs that work with various types of equipment (loudspeakers, synthesisers, etc.) to read the text and the images in textual alternatives or other visual elements displayed on the screen and convert them into voice.

All voice readers, no matter the model or operating system they are installed on, work in a similar way: they enable users to navigate their way through the operating system and various applications using voice synthesis tools as an output device (they sometimes use Braille too) and the keyboard for input, as people with visual impairments do not use the mouse.

Screen magnifiers

Software tools that enable the screen to be read in much larger magnification, making it easier for visually impaired people to see screen content. These programs not only magnify what is on the screen, they also adjust contrast and font type and size.

Screen Magnification:
A screen magnifier included in the OS operating system for Apple Mac computers.

The voice synthesis is used as support for reading documents, menus and dialogue boxes. Enables compatibility with other tiflo-technical software such as the 4.51 version of JAWS.

Voice recognition

Voice recognition is used by people who have difficulty handling the keyboard or mouse (motor impairment) as devices for inputting information into the computer. The software converts the user's voice into commands sent to the operating system, using a microphone, which results in mouse movements or key strokes.
