Imagine navigating the world with ease, regardless of your physical abilities. This is the promise of extended reality (XR), but only if we make it accessible to everyone.
When discussing accessibility in the digital world, most of us think of websites and mobile apps. But a new frontier needs our attention: extended reality (XR). XR is a combined term that includes virtual reality (VR), augmented reality (AR), and mixed reality (MR).
Let’s break down what they are:
Virtual Reality (VR) creates fully immersive digital environments. Think of Meta Quest or PlayStation VR2 from Sony, where you’re completely surrounded by a virtual world.
Augmented Reality (AR) overlays digital elements onto the real world. Examples include Google Maps in walking mode, where digital directions appear on the real-world path, or the IKEA app, which lets you place virtual furniture in your actual living space.
Mixed Reality (MR) blends real and virtual environments, allowing them to interact. Microsoft’s HoloLens or Apple’s Vision Pro (to some extent) are prime examples, merging the physical and digital worlds seamlessly.
These technologies are revolutionising the way we interact with the digital world, and it’s time we make sure everyone can join in.
I’ve seen firsthand how the industry often overlooks accessibility. In the rush to innovate, we sometimes forget that technology should be for everyone, not just those without disabilities. Making XR accessible isn’t just the right thing to do; it’s also good for business.
Imagine a world where a visually impaired person can navigate a virtual environment just as easily as someone with perfect vision. Or where someone with limited mobility can experience augmented reality without frustration. These aren’t just dreams—they’re possibilities we can achieve with thoughtful design.
Why Accessibility in XR Matters
Let’s break it down. XR is more immersive than traditional interfaces, creating entirely new environments and experiences. This immersion can be both a blessing and a curse for those with disabilities. Without proper accessibility, these technologies can create barriers instead of breaking them down.
Take, for example, Microsoft’s HoloLens. For years, the device has allowed users to control it not just with voice commands but also with eye tracking, opening up possibilities for users with limited mobility.
The HoloLens has been used as a training device, significantly reducing training time by up to 75% at an average savings of $30 per labour hour. It increases training efficiency by 60%, reduces the time to information by 97%, and significantly improves accuracy and performance post-training.
The HoloLens is also being used to support professionals in the field, such as engineers, surgeons, technicians, HR specialists, and many more, providing real-time information and guidance. This device addresses situational disabilities, where professionals may need additional support due to the complexity or intensity of their tasks.
Innovative Aspects of XR Accessibility
Innovation in XR accessibility is key to making these immersive experiences inclusive. The potential for XR to transform lives is enormous, but it requires a commitment to accessibility from the outset. Here are a few innovative approaches and examples:
Eye-Tracking Technology: Eye-tracking allows users to interact with VR environments without the need for physical controllers. This can be a game-changer for individuals with limited mobility, providing them with a more intuitive and accessible way to engage with virtual worlds.
Voice Commands and AI Integration: Integrating AI with voice commands can enhance the user experience by allowing more natural interactions. For instance, Google’s Project Euphonia aims to improve speech recognition for people with speech impairments, making voice-controlled interfaces more accessible.
Haptic Feedback: Using haptic feedback to simulate touch can help users with visual impairments navigate virtual environments. By feeling vibrations and other tactile sensations, users can gain a better understanding of their surroundings.
Context-Aware Assistance: Implementing context-aware assistance can provide users with real-time help based on their specific needs and current environment. This can be particularly useful for people with cognitive disabilities, offering guidance and prompts tailored to their unique requirements.
Adaptive User Interfaces: Creating adaptive user interfaces that can automatically adjust to the user’s preferences and abilities ensures a more personalized and accessible experience. This includes dynamic adjustments of text size, contrast, and input methods based on the user’s interaction patterns.
Shift-Left Approach to Accessibility
One critical strategy in making XR accessible is adopting a shift-left approach. This means integrating accessibility considerations early in the design and development process rather than addressing them as an afterthought. By doing so, we ensure that accessibility is a core component of the XR experience, leading to more inclusive and user-friendly outcomes.
Practical Steps to Improve Accessibility
So, how do we make XR accessible? Here are a few pointers from my practice:
- Early User Research: Conduct early user research with people with disabilities and include accessibility considerations throughout the design process. This ensures that accessibility is integrated from the beginning and helps identify potential issues before they become ingrained in the product.
- Design for All Senses: Think beyond sight and sound. Incorporate haptic feedback for those with hearing impairments and voice commands for those with limited mobility. The goal is to create a multi-sensory experience that everyone can enjoy.
- Customizable Interfaces: Allow users to adjust settings according to their needs. This includes everything from text size and contrast to control sensitivity and interaction methods. Flexibility is key.
- Testing with Diverse Users: Don’t just test your products with a narrow user base. Include people with various disabilities in your testing process early on, embracing the shift-left approach. Their feedback is invaluable and will highlight issues you might never have considered.
- Inclusive Development Teams: Hire and involve people with disabilities in your development process. Their perspectives can lead to more innovative and inclusive solutions.
I once consulted on an MR application, where we made several changes to enhance accessibility. One significant improvement was the introduction of subtitles. The app was often used in noisy environments, where audio instructions were easily lost. Subtitles not only assisted users with hearing impairments but also proved helpful for everyone using the app in loud settings. This experience reinforced the idea that designing for accessibility can improve the overall user experience for all users.
The Human Impact
When we design for accessibility, we’re not just ticking a box—we’re changing lives. I remember working on a project where we created an AR app for a museum. Initially, it was a struggle to make it accessible for visitors with disabilities. But when we finally got it right, the feedback was overwhelming. People who had never been able to fully experience the exhibits were moved to tears. It wasn’t just about the technology; it was about the human connection it fostered.
As Robert Ingersoll once said, “We rise by lifting others.”
By making XR accessible, we’re helping to lift everyone. We’re making technology stronger, more inclusive, and ultimately more human.
Let’s not wait for a mandate or a lawsuit to make these changes. Let’s be proactive, empathetic, and innovative. Reach out to your team today, start a conversation about accessibility, and explore how you can incorporate these principles into your next project. The future is immersive, and it should be for everyone.
Remember, accessibility isn’t just a feature—it’s a necessity.
