On many occasions I have seen signs, with the equivalent in Braille underneath the text. Which is great. But what baffles me is this: how do blind people know where to find the Braille text?
I don't have any photo examples right now, but in one example I was on a train and noticed a sign on the window saying "Emergency exit, break glass". Underneath that was the Braille for "Emergency exit" (note, no actual instructions). And I couldn't help but wonder, in order to be read a blind person needs to run a finger across it, but why would they run their finger across a random part of the window?
I believe its because there are universally defined standards on where Braille letters have to positioned with regards to a informational item and braille users generally learn to look for them in one location. There are also classes conducted for people with visual disabilities which inform them where to look for the sign (the class is called Orientation and Mobility) .
If placed on a door, the sign is to be in the center of the door with the centerline of the sign 5 feet from the floor. The Braille characters are to be at the bottom center of the sign. The writing on the sign is to be of contrasting color to the background.
This is the preferred position of all Braille Tactile Signs. Position the Braille Signs leading edge between 50mm & 300mm from the architrave. Heightwise the Braille Sign must be positioned between 1200mm & 1600mm from the floor surface.
The exact ISO specification is the ISO 17049:2013 which stands forAccessible design -- Application of braille on signage, equipment and appliances (Note : you will need to have a subscription to read it).
Once a blind person has learned their way round a building they know where to expect the signs to be, so for example if someone is trying to find a room on a corridor they will be as much using the sign to confirm they have come to the correct room. The sign is good for finding where a doorway is, but it is still possible someone has missed a door and is therefore at the 3rd door (ladies) instead of the 4th door.
It does not help that most blind people have lost their sight later in life and never learn to read Braille as it needs a very good sense of touch, hence Moon is often used but I have yet to see signs in Moon.
Need to find a specific app on your home screen? No problem! Either flick left or right with one finger and listen to VoiceOver read the app names as you pass them; or you can just move your finger around the screen to get an idea of the layout.
Hi! You did the right thing by publishing this blog entry, Michael, I think so anyway: it's definitely a good thing to expose the unnecessary ignorance of some mainstream journalists. I haven't read the article you refer to, but, from what you say, I can agree with you that this is definitely a bad case of a journalist getting facts wrong. Admittedly, blind people are probably only a small percentage of the i-device-using market, or of the mobile phone and tablet market in general, but the fact that three different mobile platforms, IOS, Android and Windows 8.1, can all be used successfully by blind people is proof that blind people were definitely not incapable of using touch-screen phones or tablets before the new iBraille app for the iPad came along, or before braille screen input and dictation arrived on all i-devices, come to that.
I want to make note that screen readers will not work on Windows 8.1 phones. The OS they use is Windows 8.1 RT which has most of the accessibility layers pulled out to save space on the device. In fact, the Surface tablet has Windows 8.1 RT installed. Therefore, narrator is not available. It is only with Surface pro, pro 2, and pro 3 where Windows 8.1 standard is included. JAWS (the referenced news release) can work on these devices. Unfortunately, Windows 8.1 phones use a more restricted version of Windows 8.1 called Windows 8.1 for mobile, or Windows 8.1 phone for short. This is a subset of features found in Windows 8.1 RT, and again, does not include the accessibility layers and narrator. Therefore, the only mobile phones available to blind users is IPhone and Droid.
I agree, the way the reporter described how revolutionary this app is was a bit silly. I do however disagree with the fact that we haven't been effected by the widespread use of touch screens, which is the impression I am getting from your blog post. More and more everyday things are gaining these screens, and it can sometimes prevent us from doing everyday tasks. Ovens, debit card readers, and coffee makers being just a few of the examples. And even if we're referring to just mobile phones and tablets, we still don't have the same freedom of choice. We have apple, android, which although it has many great apps, the accessibility isn't nearly as good, and if you get the wrong kind of android phone, the custom UI carriers put on could make it almost unusable, and blackberry, which has a primitive screen reader. I'm not familiar with the accessibility of windows phone 8. So I guess my point is yes, apple has made huge strides in revolutionizing access to touchscreen devices, however touchscreens haven't really been the best thing for people who are blind over all.
Apologies for my mistake in my previous post! I read in the blog entry above that Windows 8.1 computers with touch screens can be used with Narrator, and mistakenly jumped to the conclusion that Windows 8.1 phones worked with Narrator too! Although I was wrong about that, it's possible that Windows 10 phones might work with Narrator, as I gather, from what I've read recently, that Microsoft is trying to make its interface similar on all its devices. Whether that's the case in the future or not, it still doesn't alter the fact that blind people already have choice when it comes to touch-screen devices, and that they can choose to use any such device if it has been made accessible, so any claim that touch-screens are impossible for blind people to use is definitely untrue.
Great blog post as always! As for this Wired article...Gotta love bad journalism. I don't think the author even knows about VoiceOver, or iOS 8's implementation of braille input. Pretty sad really. It's like she completely ignored it when people mentioned VoiceOver.
the largest area that blind people have been impacted negatively from an accessibility point of view are the touch screen ATM machines being used by most merchants. I was at a retailer where this was being used, and had a very bad experience. Unfortunately, the retailer did not have the older debit machine, and it was either dictating to the assistant my pin code, or pay by cash. Given that I didn't carry enough cash on me on hand, I was unable to make the purchase as I refuse to tell an assistant my pin. This is a very troubling trend and I shutter to think what will happen when it becomes even more mainstream.
This is another nice blog post, and it's partially why I've come to rely on AppleVis so much for help with my Mac. Although I've never owned an i-device I did get to test one out recently. I was emailed by a tech professor and one of her PhD. students at a well-known local university, and they asked me if I'd be willing to help out with an experiment they were conducting with regards to these touch-screen devices. I probably can't say much more than that, but it was rather interesting nonetheless. I haven't heard from them though for a little while, so they must have either abandoned the whole idea or something. I know that the student didn't graduate yet, as this was only a year ago. Now that I think about it, some of the Braille labels fell off my microwave and I've had very little if any trouble at all trying to press the right buttons. I'm going to discuss this with my parents next weekend though and try to get the label gun back, when I'm home for my birthday celebration with the family. Regarding the Wired article, I think it just goes to show how much educating still has to be done by those of us who use assistive technology and I think Apple products specifically.
Actually Narrator is on Windows RT and Windows phone 8.1. So yes WP is another option. While it isn't as feature rich as iOS, it's good that the choice is available. I'm hoping they improve it in Windows 10.
I also agree that it's not fair to say touch screens haven't had a negative impact on our lives as blind people. Sure mobile screen readers are awesome, but they don't exist on a lot of the devices that are increasingly using touch screens. Redbox anyone? Not to mention the point of sale machines. That is something I think all the blindness organizations need to fight to effect some change with. I don't always like whispering my pin to a friend if I'm with them, or having to tell it to the person behind the counter.
Anyone else seen the awesomeness that is Coke Freestyle machines? I like to jokingly say they're the second best thing ever invented after iPods. They have a zillion different flavors of sodas in them and you can mix them up if you want. Their only drawback? Yep, a touch screen, therefore, I have to get the person behind the counter to fill up my cup, and do it again if I want a refill.
When I lived on campus at college, they rebuilt the dorms a couple years ago, and with them came a high tech cafeteria. They have touch screen kiosks where you select what you want, and then you swipe your student ID to finalize your order. That meant I had to get the person in the little store to come out and read me the menu and make my selections for me. I used to say they should have a smart phone app you could use to make your order, but one of my friends who works there thinks students would just abuse it and give their friends free food. She took me shopping one day and I had to use one of those point of sale touch screens, and she finally realized why I didn't like the touch screens in the cafeteria. Her comment was "I don't think they thought that one all the way through."
