Re: If default navigation is not keyboard accessible does an alternative access mean it still passes AA WCAG?

Thanks Kristina for you thoughts on this.

In light of your input - can I ask you what you prefer between these two options (or if you don't prefer any what's better):

At the moment each virtual room is accessible from a menu at the top of the page. Should the alterantive version be accessed via a link on each of the exiting pages? I.e. on every default virtual tour page there is a link to the accessible version of that same page.

Or should there be an extra item added to the existing navigation that links to an alternative version of the entire tour? The alternative version mimics the structure of the default version but each page is an accessible video rather than the virtual tour version?

They were talking about automatically detecting if someone was using a screen reader and taking them automatically to the alternative version. I discouraged them from doing that as I never think it's a good idea to take control away from the visitor. They don't know why someone is using a screen reader - so they could actually end up making the tour inaccessible to some people and they are taking away their choice.

If anyone disagree with my opinion on that I'm happy to hear your arguments.

Thanks for your input.

All the best,
Jim

There's a virtual tour that has an alternative version that doesn't "pass" as they didn't fully understand what went into an alternative version (i.e., a knowledge of the various personas that would use that conforming version). They created a one pager that has load issues depending on the amount of videos you have and is generally exhausting to navigate as someone using keyboard only or someone with low vision (it has the heading and landmark structure for people using screen readers but, again, as a one pager, even that can be exhausting due to the length of the page). That same alternative version has gone out of sync with the non-conforming version so the only way to confirm it will stay in sync when a vendor is managing the conforming version is to cross your fingers and wait for nothing to go wrong with the conforming version. It's also extremely easy for a vendor to make a code change that impacts the conforming version and makes it non-conforming. Just some thoughts as it's actually pretty hard to ensure a conforming alternative version is kept equally effective and is maintained in the long run. Having tested alternative versions of products outside of virtual tours as well, I've yet to come across one that actually conforms (or if it does, continues to conform).
