What is accessibility?
In IB Computer Science, accessibility refers to the design of hardware and software systems that enable people with disabilities or impairments to use technology effectively. It ensures that digital resources, applications, and websites can be accessed and used by as many people as possible, regardless of physical or cognitive limitations.
Why is accessibility important?
Accessibility improves user experience and inclusivity by providing features such as:
Screen readers for visually impaired users
Keyboard navigation for users who cannot use a mouse
Voice recognition for users with mobility impairments
Colour contrast adjustments for users with colour blindness
Accessibility and the Web
In web development, accessibility is guided by standards such as the Web Content Accessibility Guidelines (WCAG), which define best practices for making websites usable for people with disabilities.
