We all visit websites for similar reasons regardless of the technology we use to interact with it. A person who is visually impaired will use a bank’s website to pay a bill with the same intent as someone who doesn’t use assistive technology. A person using their mobile device requires the same functionality of someone using their desktop. Just as a good site design will have considered the requirements of different screens, good site design needs to consider a variety of users’ needs and accessibility issues. This is called Web Accessibility.
