When will the bus come, an introduction to the real time information app
with VoiceOver
For many visually impaired people, using public transport is the only way to
get to where you need to go. One thing is for sure though, it's really
helpful to know when the bus is going to arrive, am I only going to be
waiting two minutes? or would I be quicker going to the stop across the
road. There is as they say an app for that. but is it accessible? In this
article we'll try to answer that question.
What does the app do?
The idea here is simple. You have a list of upcoming buses for a given stop,
and the app tells you how long before they are expected to arrive. For
example, it might show a 341 in five minutes and a 343 in 12 minutes, it
basically just gives you an idea of how long you're going to need to wait.
Is it accessible?
Well, sort of.
It is possible to get the information you need, but you might need to jump
through some hoops to get it.
The first problem you'll hit is adding your stop. Every bus stop has a
six-digit number that identifies it, I assume this is written somewhere, but
unfortunately, I can't see it. So let's say I'm at stop 354643, if I enter
that stop number I can get all the info I need, but I can't enter it if I
don't know it.
The other way to find your stop is to use your phone's location data. The
problem here is that if there are other bus stops nearby its easy to get
mixed up. I tried using it on a Main Street here in cork and because there
are so many stops in that area, it was basically useless.
But let's pretend you do get it set up. You have all the stops set as
favourites, and you know where you're going. Then can you use the app
accessibly?
Yes. Once the app is set up, its basically good to go. Voiceover gives you
most of the info that you need, and it's possible to get an estimate of when
the next bus will arrive at your stop.
Unfortunately, some information isn't read by voiceover so you are left
doing a bit of guessing, you can't find out if the app is pulling from live
information based on the bus's movement, or if it's based on a pre-planned
timetable. This information is visually represented by a flashing blue icon,
but unfortunately voiceover doesn't read it. You might be able to see this
if you have low vision but for users who can't see the screen your
unfortunately out of luck.
The other interesting item that voiceover misses is the bus number. You'll
hear where the bus is going, but not its number. This info would be nice to
have, but it really isn't a necessity as your finding out where the bus is
heading anyway.
So, what's the takeaway?
The app is useable but is far from perfect. My sighted brother had to set it
up for me and add my regular stops to my favourites, (that obviously
shouldn't be necessary), but now I am able to use the app just fine. There
are some basic features that I think could improve accessibility so I'll
list them here, but in general it can be a useful tool.
1. There is no dark mode, adding this might make life easier for some with
low vision.
2. We should be able to hear the bus route number in the list when flicking
through with VoiceOver.
3. Finally, my most ambitious dream. Why can't we have some scannable thing
at bus stops that lets me add a stop to my favourites without knowing the
stop number. A QR code or NFC tag could do this.
It's a shame that such a useful tool isn't more accessible, but at least its
useable with some work arounds. I'd recommend downloading the app and giving
it a try to see how it works for you, but I would be aware that it certainly
isn't the smoothest experience.
