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 experiencing a disability.
Accessibility hardware is understood to be designed for a specific number of people who are designed for a specific purpose to help them 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 all these devices, any disabled person can run the computer easily, which was not possible before.
There are many standard accessibility options already included in today’s modern operating systems that help the user use them, and they do not need any specialized external 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 the text so that 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
iOS: Settings → General → Accessibility
Android: Settings → Accessibility
