Users with visual disabilities either don’t have vision or have a very low vision, which makes it difficult for them to look at the user interface (like a computer screen or mobile device screen) and hence, they use an assistive technology called Screen Reader which reads the contents & controls of the screen and helps users with visual impairment use computers & other software applications.
Screen Reader is a software which converts the visual information coming from the computer screen to speech or braille using a speech synthesizer. Screen reader reads the following:
Static texts - Headings, paragraphs, line of text, etc.
Alternative texts for images & other graphical elements
Name, role, value, status (as applicable) information for interactive UI elements (like, buttons, input fields, links, checkboxes, etc.)
Programmatically associated text like, labels for form elements, corresponding column headers for table cells, live announcements, error messages etc.
Some of the popular screen readers are as follows:
Screen Reader enables person with visual impairment use computer & other software application, access & collaborate on internet & social media, play computer games, communicate through email & other messaging software, write a program, etc. and perform their job or task independently.
