The Hague (The Netherlands) is redesigning one of its parks. It is asking
its citizens to choose 1 out of 3 options: A, B or C. It is using a "virtual
tour <http://clients.skycap.com/gemeentedenhaag/dehorst/tour.html>;" to
present the options.
But this virtual tour has accessibility issues, in my view.
Personal thoughts:
- Make navigation keyboard accessible (including focus indicator)
- Give screenreader users (hidden) hints: "to the right", "to the left",
"zoom in"
- etcetera...
Challenges:
- Text alternative for what is basically one big image...
Does anyone know how to make this accessible?
Kind regards,

Keep in mind that screenreader users will get little value out of just
having controls labelled, if the underlying content that they're
navigating with them is also not accessible. So instead of thinking in
terms of SR users, it'd be better to think of this (adding correct
accessible names to controls) in light of speech-recognition users, for
instance, who will be able to then trigger the controls more naturally
(provided the accessible name is shown/exposed visually somehow, maybe
with a toggle-able hints/labels control which shows/hides them)

Fundamentally, the nature of the virtual tour is to simulate the
experience of walking around the park. Beyond a text-based description
of the park itself, there's probably little point in doing anything
"interactive" here for non-visual users (there's no point for them to
navigate left, right, zoom in, etc unless you plan on providing a
separate description for each stop/location, which would still be an
inefficient way compared to a separate text description which simply
describes the features of the park).

@Patrick: Thanks for your remarks!
Regarding screenreaders: I always thought that screenreader use wasn't limited to people with a visual impairment. People with cognitive disabilities also use a screenreader. So, wouldn't it be best practice to add screenreader functionality to the navigation ('to the right-, 'zoom in- etcetera) for these particular users?

Labelling controls properly would be good practice, yes (and I think I
did suggest that I'm my email, also for speech users). My comment was
mainly about not trying to make the visual tour work as is for blind
users, that a different alternative (like a well structured text
description of the park and its various features) would serve this user
group better than something they'd have to spatially navigate.
