Examples of output devices:
Designing products in a way so that they can be used by disabled users. Since computers have become such a vital part of our modern lives, computers have become more accessible.
Examples of accessible input devices:
|Device||Users||Function||Braille keyboard||Visual problems||The buttons have engravings, which blind users can feel and read. This enables users to know what they are typing.|
|Foot-Mouse||Mobility problems||This special type of mouse can be operated with a foot. It helps users to navigate interfaces.|
|Speech-to-text||Mobility problems||Users speak into a microphone, and this software converts what they said into text.|
Examples of accessible output devices:
|Device||Users||Function||High contract monitors||Visual problems||These monitors display everything with high contrast. This makes things clearer, and easier to see.|
|Braille printer||Visual problems||They emboss braille onto thick paper, meaning users can use touch rather than sight to read what is being displayed on their screen.|
|Text-to-speech||Visual problems||Text that is being displayed on screen can be read out loud with this special type of software.|
