Assistive Technology Focus: Screen Readers
…the Internet can mean many things to people with a disability: a luxury, a necessity, a way to participate in the information society, a way to gain access to more information than was previously available, or only one of the many ways of accessing information. It is also seen as a technology which may potentially disadvantage them if they cannot access it.

What is a Screen Reader?
Imagine online shopping or editing a Word doc without being able to see the screen. If you have vision that may seem impossible, right? Fortunately, people with visual impairments can accomplish both tasks using a screen reader.
Screen readers are a type of assistive technology that read the text and interactive components on a computer screen aloud. A keyboard controls what is happening on screen (in place of a mouse). Below is a video from University of Wisconsin-Milwaukee Assistant Professor Rakesh Babu on how screen readers work:
A Brief History of Screen Readers
The first screen readers emerged in the late 1980s when an IBM employee developed one for his coworkers with low vision. This invention blossomed into one of the most influential devices enabling folks with visual disabilities to access the internet, computers, and ultimately, information.
Screen readers aren’t only for people with visual impairments. They can also help others, like those with dyslexia, motor disabilities, and cognitive disabilities.
Making Screen Readers Work
Screen readers won’t automatically work as intended. Websites and apps need to be built with the proper markup and structure for screen readers to function correctly. Below is a video that illustrates how coding a web page without adhering to accessibility guidelines can result in confusion and insufficient information for users to understand what is on the screen.
Please note: This video is from 2014. Here is the New York Times’ page on accessibility.

So, we can’t just assume that all websites, applications, and other IT products are compatible with screen reader technology. We need to build these products with accessibility guidelines in focus, or we risk defeating the crucial purpose of these advances. As Prof. Babu noted, “With a little bit of understanding and compassion, designers can build technologies that are more blind-friendly.”
