Visual impairment is a condition affecting more than two billion people around the world. While the vast majority of visually impaired persons will be able to improve their vision by wearing prescription lenses, others aren’t so fortunate. For them, the world is blurry and dark.
Societies around the world have taken great strides in providing the visually impaired with the tools and resources required to lead happy and productive lives. For instance, most major cities include audio indicators at their crosswalks to make it easier for visually impaired pedestrians to traverse their streets safely.
Another prime example of a product that makes life easier for the visually impaired is what is known as a screen reader app. It’s what it sounds like; an app that reads out what’s on the screen. They’re vital tools for helping the visually impaired use modern technology.
While screen reader apps are incredibly handy and exceptionally useful, they’re far from perfect. There’s a lot that users need to know about screen reader apps in order to make the most of them. With this in mind, let’s take a look at six factors to consider when it comes to screen reader apps:
Operating system compatibility
As of now, there’s no universal screen reader app; each operating system has its own version. For instance, the Talk Back app is Google’s screen reader for Android devices. Meanwhile, iPhone and MacOS users rely on an app known as VoiceOver. While they’re similar, they’re not identical, requiring individuals to understand the differences in terms of functionality and user interface.
File type compatibility
Smartphones, tablets, and traditional desktop computers are frequently used to access various files. For those who rely on screen reader apps, the array of different file types can pose problems. For instance, some screen readers are unable to translate information found in PDF files, while others are hit or miss when it comes to certain image files. Generally speaking, it’s a matter of trial and error when determining whether or not a particular screen reader works with a specific file type.
Different types of screen readers
While most operating systems come with a pre-installed screen reader app, these aren’t the only options available. For example, a variety of standalone screen reader apps can be installed by the user. There’s also web-based screen reader software that can be accessed through a web browser. Each option offers its own set of pros and cons.
Keyboard shortcuts
It goes without saying that visually impaired individuals rely on keyboard shortcuts in lieu of clicks, swipes, and taps. Unfortunately, each screen reader app has its own shortcuts, requiring users to become familiar with a new set every time they use a different option. As a result, most individuals who depend on screen readers tend to stick to one or two options and avoid the others unless absolutely necessary.
Additional features
Each screen reader app has its own series of additional features. Some have magnifying features to help users access details they may otherwise be unable to see, while others provide ways to adjust the text-to-speech voice. It’s important to take these features into consideration before going forward with a particular screen reader.
Support options
Apps and software are difficult to master in general, so when it comes to assistive technology like screen reader apps, support options are critical. Look for screen readers that come with accessible manuals, tutorials, and online support communities. Some may offer straightforward customer support to users. The more support options you have, the easier it will be to learn how to use a particular screen reader app.
Visual impairment is a condition that impacts the lives of billions of people around the world. Thanks to infrastructure improvements and technological advancements, the visually impaired’s day-to-day experiences are made better than in years past. In today’s increasingly digital world, the visually impaired need screen reader apps more than ever. By knowing the limits of these apps as well as the options available, those who need screen readers will have a better time putting them to optimum use.
