Screen Readers, an Essential Tool
Welcome back to our series exploring assistive technology for individuals who are blind or visually impaired! In our previous post, "Assistive Technology for the Blind and Visually Impaired: An Overview," we explored a wide range of tools and devices that enhance independence and accessibility. Today, we will dive into the realm of screen readers, the indispensable software that bridges the gap between the visual and digital worlds.
Converting Visual into Audio
Screen readers are amazing programs that translate on-screen content on computers, smart phones, and other devices (including some TVs - check out Audio Guidance on an LG TV), into synthesized speech or braille output. They act as virtual narrators, guiding users through web pages, documents, and applications, providing auditory or tactile descriptions of layouts, content, and interactive features. Imagine reading a book from left to right and top to bottom - screen readers follow a similar pattern, presenting information in a logical and organized sequence.

Popular Screen Reader Options
Several prominent screen readers have established themselves as powerful tools for digital accessibility:
JAWS (Job Access with Speech): A comprehensive and highly customizable screen reader for Windows. It has many built-in settings and features that work well specifically with the Microsoft suite of tools, including Microsoft Edge, Word, Excel, etc. JAWS offers both one-time purchase and subscription-based licensing models.
NVDA (Non-Visual Desktop Access): A free and open-source screen reader for Windows, providing a user-friendly and inclusive experience. NVDA's active community drives its ongoing development and enhancement.
Windows Narrator: Built-in to the Windows environment. This uses similar keyboard shortcuts and modifier keys as JAWS. In years past, this was a last resort or only used if JAWS or NVDA were not working properly. But as of late, with Microsoft’s accessibility push, they have made Narrator significantly better, with parity starting to match that of the other screen readers available for Windows.
VoiceOver: Apple's seamlessly integrated screen reader for iOS and macOS devices, built into iPhones, iPads, and Mac computers. VoiceOver delivers a smooth and intuitive way to navigate Apple's ecosystem. To explore the full range of Apple's accessibility features, visit their dedicated webpage: Apple Accessibility - Vision.
TalkBack: Android's counterpart to VoiceOver, pre-installed on Android smartphones and tablets. TalkBack offers Android users a familiar and accessible interface.
Mastering Keyboard Navigation
While screen readers provide auditory or tactile feedback, effective navigation and interaction often rely on keyboard commands and shortcuts. Users must familiarize themselves with the keyboard layout and learn specific key combinations to interact with various elements on the screen. These shortcuts allow users to quickly move through content, activate links, open menus, and perform various actions without relying on a mouse. Learning and memorizing these shortcuts is essential for efficient screen reader use.
Each screen reader has its own set of commands and modifier keys. For example with JAWS, many keyboard shortcuts include the JAWS Key, which is either mapped to the Caps Lock Key or the Insert Key (the zero on the number pad). For VoiceOver on iOS or MacOS, they have what’s called the VoiceOver key, which is mapped to pressing Ctrl and Option at the same time or the Caps Lock key.
Screen Readers in Action
Screen readers open doors to a wide range of digital activities, including:
Browsing the web: Accessing online information, news articles, and social media platforms.
Using productivity software: Creating and editing documents, spreadsheets, and presentations.
Enjoying multimedia content: Listening to music, podcasts, audiobooks, and other digital media.
Engaging in online communication: Sending emails, instant messages, and participating in virtual meetings.
Fostering Independence
Beyond their technological capabilities, screen readers are powerful tools for fostering independence, education, and employment. By ensuring equal access to the digital world, they empower individuals with visual impairments to participate fully in society and pursue their dreams.
Embracing Digital Inclusion
If you or someone you know could benefit from a screen reader, don't hesitate to explore the options available and discover the transformative power of these incredible tools! Remember, accessibility is a fundamental human right, not a privilege. Let's continue working towards a digital world that is truly inclusive and accessible for everyone.
