Accessibility means designing products and environments that are helpful to people with disabilities (disabled). For example, wheelchairs, entryway ramps, hearing aids, and braille signs.
In the IT world, accessibility means designing hardware and software to help people who are experiencing a disability.
Accessibility hardware is considered to have been designed for a specific purpose for a selected number of people so that they can help it operate the computer.
For example, accessibility accessories such as keyboards on which keys are written in capital letters, large-sized mouse and trackable, puppy switches are activated with very little pressure. With the use of all these devices, any disabled person can run the computer easily, which was not possible before.
In today’s modern operating systems, there are many standard accessibility options already included which help the user to use them, and they do not need any external specialized hardware.
For example, in both Windows and macOS OS , Display Modification options, such as Magnification and Investing Colors, are already included, which can help the user with eye problems. Speech can also be triggered from text, so that mehjud text can be easily heard on the screen. Dictation can also be used to perform common tasks with the help of vocal commands .
You can easily access the accessibility option from the steps mentioned below in your operating system:
Windows : Settings → Ease of Access
macOS : System Preferences → Accessibility
