Individuals who are visually impaired and want to access a computer or a smartphone need to have an alternative to the video screen that translates the screen information in speech or in braille. These alternatives are called ‘screenreaders. Here are some videos about the in-built screenreaders available in the most used operating systems in present-day computers and smartphones.  

These screenreaders are also coupled with keyboard shortcuts, gestures for touchscreen devices and voice commands to take inputs from the user. For example, Voiceover and Talkback are gesture-based screenreaders for iPhone and Android phone respectively.

Persons with vision impairment use them along with the in-built voice commands to navigate the mobile phone interface.
