Navigating Accessibility Testing (TalkBack/VoiceOver)

Today, I want to dive into something super important yet often overlooked in the tech industry: accessibility testing. Specifically, I’ll be talking about using TalkBack on Android and VoiceOver on iOS, and why this is crucial for creating inclusive apps. As someone who doesn't typically use accessibility tools but needs to understand them for work, I’ve found TalkBack easier to navigate, and I’m excited to share my journey with you.

Why accessibility matters

Accessibility in tech is about making sure everyone, including people with disabilities, can use digital products. It’s not just a nice-to-have feature; it’s essential. Think about it: if a person with vision impairment or low vision can’t use your app, you're excluding a whole group of people. We should strive to create products that everyone can enjoy, no matter their abilities.

The tools: TalkBack and VoiceOver

TalkBack and VoiceOver are screen readers that help users navigate their devices by reading out loud the content on the screen. Here’s a quick rundown:

TalkBack (Android): Provides spoken feedback, gestures, and vibration to help users interact with their devices. It reads the text on the screen and describes actions, like clicking a button.
VoiceOver (iOS): Similar to TalkBack, VoiceOver offers spoken feedback and lets users control their iPhones, iPads, and other Apple devices. It also supports braille displays for those who prefer it.

My personal take: why TalkBack stands out

Even though I don't use these tools regularly, work has made me dive into both. Surprisingly, I found TalkBack a bit more user-friendly. Here’s why:

Gesture-Based Navigation: TalkBack’s gestures feel more intuitive and easier to pick up. Simple swipes and taps make it straightforward to move through content.
Customisation: It’s highly customisable. You can tweak the settings to fit your needs, whether you’re a casual user or someone who relies on it daily.
Vibration Feedback: This feature adds another layer of interaction, helping users feel more connected to their devices.

But hey, don’t get me wrong - VoiceOver has its own set of strengths. Often, the choice between the two boils down to whether you're team Android or team iOS.

Why We Should All Care About Accessibility Testing

So, why should we prioritise accessibility testing? Here are a few reasons:

Legal Stuff: Many places have laws requiring digital accessibility. Ignoring this can lead to lawsuits and fines.
Reach More People: Accessible apps mean more users. You’re not just ticking a box; you’re opening your product to a wider audience.
Better User Experience: Accessibility features often improve the overall user experience. Captions, for example, aren’t just for people with hearing disabilities - they’re useful for everyone in noisy environments.
Doing the Right Thing: It’s about being responsible and ethical. Creating inclusive products is the right thing to do, period.

Practical examples of accessibility in apps

When it comes to making apps accessible, the devil is in the details. Here are some practical examples:

Buttons: Ensure buttons are large enough to be easily tapped. Use descriptive labels for screen readers, so instead of a button just saying "Click here," it should describe what it does, like "Submit form" or "Play video."
Text: Use high contrast between text and background to make it readable for users with low vision. Allow text to be resized without breaking the layout of the app.
Navigation: Provide a logical and consistent navigation structure. Screen reader users rely on a predictable flow to move through content. Use landmarks and headings to help them understand the structure of the page.
Forms: Label form fields clearly. Each field should have an associated label that screen readers can detect, ensuring users know what information is required.
Images: Include alt text for images. This text should describe the image’s content or its purpose, providing context for users who can’t see it.
Multimedia: Provide captions and transcripts for videos and audio content. This not only helps those with hearing impairments but also makes content accessible to users in noisy environments or those who prefer reading over listening or non-native speakers.

My Journey with TalkBack and VoiceOver

Navigating these tools has been eye-opening. It's given me a deeper appreciation for the challenges people with disabilities face and the importance of designing with them in mind. Here’s a bit about my experience:

Learning Curve: At first, it was a bit tricky to get the hang of the gestures and commands. But once you get used to it, it becomes second nature.
Real-World Testing: Testing our apps with TalkBack and VoiceOver has highlighted areas where we need to improve. It’s one thing to think your app is accessible and another to see it in action.
Empathy and Understanding: Using these tools has made me more empathetic towards users who rely on them. It’s not just about ticking boxes; it’s about genuinely understanding their needs.

A Call to Action

By integrating accessibility testing into our development process, we’re not just meeting legal standards - we’re setting new benchmarks for quality and user satisfaction. Imagine your app getting a five-star review not just for its cool features, but because it’s usable by everyone, regardless of their abilities. Picture your team creating software that’s not just cutting-edge but also inclusive. That’s the real win. Let’s make accessibility our competitive edge.
