The Need For Accessibility Testing

Accessibility Testing

According to the World Health Organization (WHO), 15% of the population have a disability, which is the reason Accessibility Testing has become important.

Some of these technologies include, screen magnification software, screen readers, speech recognition software, special keyboards to work and for communication, and more.

However, there are various innovative products, applications and websites that are not user-friendly and accessible to everybody. Accessibility Test is geared towards normal users as well as users with different types of disabilities. Accessibility Test not only focuses on verifying usability, but it makes sure that an application can be used by people with many disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

How to Perform Accessibility Testing?
