Virtual Reality Accessibility

There's a lot of information out there about designing the web for accessibility. Over the last 10 years, the world has learned a lot about how to accommodate a vast diversity of different needs and abilities.

So, when it comes to designing virtual experiences, we don't need to start from scratch. Here's a few things you should consider from a VR Accessibility point of view.

Seated-first design

Like responsive web design, which accounts for the screen size of the user, VR experiences should be responsive to height and posture. Consider audiences who use wheelchairs, are unable to stand for long, or are short (including children).

  • Don't place buttons or interactive elements in hard to reach positions
  • Ensure that NPC eye-gaze includes height, not just direction
  • Include locomotion options which can be done from a seated position

Audio cues

VR experiences shouldn't rely solely on audio cues to grab a user's attention, or require audio in order to complete a task. Not only does this allow your experience to be accessible by hearing impaired people, it also let's users play on mute if they want to.

  • Provide a subtitles option for speech
  • Provide visual indicators where positional audio is used
  • Provide visual cues for success or failure events (e.g. failure to start an engine should be visible as well as audible)

Readability

Current hardware resolutions make it difficult enough to discern text as it is. But as the resolution of VR headsets increases, don't be tempted to reduce font sizes to match resolution. Consider users with a vision impairment that may not be able to make out small text.

  • Recommended font size is 3.45°, or a height of 6.04cm from the distance of one meter
  • The text should be faced perpendicularly to the observer, and rotate around the observer's view
  • Use a line length of 20—40 symbols per line. With bigger fonts, lines should be shorter.

More information on fonts in VR can be found in Volodymyr Kurbatov's article.

Colour

Color blindness or color vision deficiency (CVD) affects around 1 in 12 men and 1 in 200 women worldwide. This means that for every 100 users that visit your website or app, up to 8 people could actually experience the content much differently that you’d expect.

Virtual worlds tend to be visually rich, which often means a much broader range of colour than one would typically see on a website, or even in the real world. With this in mind, strive to ensure that colour isn't used a the only way of displaying contrast.

  • Choose a variety of textures to provide better contrast between visual elements
  • Use both colours and symbols in interface design
  • Avoid "bad" colour combos (e.g. Green + Red, or Blue + Purple) for primary elements

VR is still in it's infancy – we're still learning about what works and what doesn't. As the industry grows, it's important to continue prioritising accessibility, so that our virtual stories, games, environments, and tools can be explored by everyone.

The Next Tech Revolution

When the internet was popularised, the world started asking questions about topics like freedom of access to information, the nature of "digital goods" / "digital ownership", and globalisation.

Now that we're on the cusp of the next technology revolution, I'm excited about more compelling questions entering the zeitgeist.

Virtual Reality is currently being pushed forward by a gaming market (like computing once was). But it won't be long (2019, 2020) before consumer VR starts making its way into every home. All we need is:

  • Standalone headsets (no computer required, coming 2018—2019)
  • Faster wireless communication (5G, coming 2020—2021)
  • Cloud rendering (2018—2019)

Once VR has become popularised, the global conversation will shift to focus on some very interesting questions. What is the nature of reality? Do quantum mechanics prove that we're already living in a simulation? Is consciousness emergent from biology, or something deeper? Does "self" even exist?

At the same time, I hope we see this technology creating new social dynamics, forming new partnerships and friendships, in ways that flat screen communication has never been capable of. 

I don't think we'll recognise the world 5 years from now.


Postscript: One of my earliest VR experiences was sitting in AltSpace and meeting a Rabbi. We discussed the future Halakha (Jewish law) of VR for hours. Is flying around Google Earth considering "travelling" on the Sabbath? Should my avatar wear a kippah? Is my avatar Jewish? Is it permitted to eat virtual pork? These are questions that will have real authoritative answers in the near future.

Back to Bookmarks

Here’s a productivity tip I’ve rediscovered, straight from 2003: Browser Bookmarks.

Since I left social media, I found it hard to keep track of four things:

  1. News (from sources I care about)
  2. Blogs (written thoughtfully and regularly)
  3. Photos (from family and friends)
  4. Videos (information and entertainment from sources I trust)

My first inclination was to turn to RSS – the ancient XML format that kept everyone up to date in the 2000s. But RSS is dying, and I believe blogs should be read in the context of their site (design).

Instead, I started using the browser feature that’s been with us since Netscape: ⭐️ Bookmarks! I created a folder for each of those four categories, and whenever the mood strikes me, I just right click and choose “Open in New Tabs”.

News and Blogs are self explanatory, but it bears stating that you can still follow Instagrammers and YouTube channels without an account on their service.

You can view any public instagram account online by visiting https://instagram.com/[username]

For YouTube, I like to visit the channel page, then click on the Videos tab, and bookmark that. This way I’m always seeing a list of the latest videos from that channel. I also use 1Blocker to block cookies from Youtube (so that the videos I watch don’t result in “Recommendations”).

I hope you’ll consider hitting Command+D (or Ctrl+D), and visiting this blog again soon.

Something Daily

Inspired by Seth Godin, I recently attempted a daily writing project. I committed to write one blog post every day, indefinitely.

Here are my reflections.

Writing takes time. Not the actual typing – that part is easy. But finding inspiration everyday is a serious commitment. It can take hours, and it can't be forced.

Sometimes opening yourself up to inspiration means sitting in a café reading a magazine, or going for a stroll through the park, or reading a book. Let's be real: I have a family and a job, I don't have time to wistfully wait in the bath for my eureka! moment every single day.

After a few months, I gave up. And when I gave up… I really gave up. I didn't write again until… well, now.

I've realised that, at least for me (and maybe for you, too?), trying to force a daily routine isn't the best way of falling in love with a habit or practice. I advocate for a different approach. Let's call it…

No Pressure Weekday Habits

I'll illustrate this habit-building technique with an example: Meditation. I love meditation, but I haven't always. At first, I only loved the idea of meditation, the practice took some getting used to.

All the books I read told me that it was vital that I meditate every single day for the first 3 months (a common trope among daily habit pushers). Other books told me to start with just 5 minutes a day (or write only 1–2 sentences, or run for only 1km).

That wasn't working. So instead, I decided to commit to the following:

Meditate for at least 30 minutes, but only on weekdays, and only if I feel like it.

In the end, I found that my intuition here worked wonderfully. It was the pressure of not missing a day which caused me to give up. It was the triviality of "small habits", that caused me to give it away. Now, I often happily meditate for 20—30 minutes, and I do so most days.

So, back to writing.

After a few days of writing every day, I started feeling stressed, worried, and overworked. Worse – the short posts were often uninspired or forced. That's not the sort of writer I want to be.

Instead, I'll be the writer who taps out a decent chunk of valuable content every single day.

But only on weekdays, and only if I feel like it.

Pixel Art

It’s very important to me to be a creator, not just a consumer.

It’s very easy for me to consume, and consume, and never stop. It’s hard to let the inspiring inspire.

Recently I came across a Kickstarter project for an 80’s arcade themed game 198X. This time, I couldn’t help but be inspired by the retro art style. So, I decided to give it a go for myself.

My kids, pixel art style. @10x

After a half-day of art history study, tutorials, and practice, this is the result. I’m really happy with it, and I’ve resolved to keep practicing. Maybe animate those little limbs and create a side-scroller?
