An Introduction to Screen Readers: A Way to Use a Computer without Sight
Back in the dim and distant past when I became blind, using a computer was a very different process from what it is now. Back then I had to use a special computer that barely resembled the computers my friends were using, and the amount I could do with it was limited.
Nowadays I, and many other blind people, use a standard laptop or desktop together with a software application called a screen reader. With a screen reader we’re able to accomplish almost anything that a sighted person can. Which means that we should be able to fulfil the requirements of most of the many jobs requiring the use of a computer.
Essentially, a screen reader is a programme that allows us to interact with a computer using audio. We have the option to either type or dictate to create documents, e-mails, spreadsheets or other text-based programmes. We can access menus, online content and documents created by others using the audio functionality. And there are ways we can access the content in images, graphs and diagrams.
So why then do so many people have difficulty in believing that a blind person could be successful in a job?
Maybe they believe that the software to allow a blind person to use a computer is expensive. And, certainly some of the screen readers do have a cost associated with them – as do many other software programmes used in business. But there are many different types of screen readers available nowadays, at a range of price points.
In fact, screen readers are in-built into several operating systems at no extra cost – IOS/Mac, Android, Microsoft are a few that spring to mind. That’s not to mention the many other applications that are out there – JAWS, Supernova, NVDA to name but a few.
And sure, each of these differ in what they offer and what they cost. But, for the purposes of this article, that’s detail and would depend on the preferences of the individual, the needs of the organisation, and the tasks required.
My point remains the same – with so many jobs being accessible to someone who is blind, why aren’t there more blind people being employed?
If you want to learn more about how I use a computer in my work life, please feel free to contact me through my website: www.loisstrachan.com and let’s chat about what I can and cannot do using a computer… I’m almost willing to bet you’d be amazed!
In my next article in this series I’m going to be talking about an app that helps the blind community to access print material and other physical objects more easily – or, maybe I should say one of the ways, since there are a few that I’ll be talking about in this series.
