Deaf users Deaf users are able to access Internet in much same way as able-bodied people with one key exception – audio content. If it is a key function of your website for people to be able to hear a message, then be sure to provide written transcripts.
Keyboard/voice only users Some of your site users do not have access to a mouse when browsing Internet. Try putting yourself in their position by navigating your website using only tab, shift-tab, and return keys.
Other users Other people who may access your website that have disadvantages include: 1 Epileptic users who must always be careful to avoid seeing flickering between 2 and 55 Hz 2 Web users from outside your industry who may not understand industry jargon or acronyms 3 Web users whose first language is not English and who may not be able to comprehend complicated language
