Is Your Site Accessible?

As a blind computer user the issue of web accessibility is close to my heart. Prior to addressing the matter in hand it may be helpful if I sketch out how people who are unable to read print access the web.

I lost the majority of my vision at about 18-months-old. I can see outlines of objects but lack sufficient vision to read my computer’s screen. How then do I navigate the internet?

Blind computer users utilise screen reading software which converts the text on screen into speech and/or Braille allowing the visually impaired person to navigate the web. In my case I use Jaws (http://www.freedomscientific.com/Products/Blindness/JAWS) on both my work and home computers.

So, if you use Jaws and it allows you to access the internet what is the problem? Surely everything in the garden is rosey?

No, unfortunately not.

So what problems do you encounter?

  1. Links rendered as photographs or other images with no text to identify them. Jaws and other screen reading software can only interpret text. On encountering an image it sees only a blank page or, on occasions will announce “image” without stating the nature of the photograph. When encountering a series of links, rendered as images the only way in which a screen user can ascertain their meaning is by clicking on each one. Imagine a webpage consisting of several hundred links rendered as images. In most cases the blind computer user will give up in frustration and move on to a more accessible site meaning that the web site owner has lost a potential reader and (if the site sells products) possibly a sale also.

So should I not put photographs on my site?

We live in a predominantly sighted world and it would be wholly unreasonable for anyone to expect web site owners not to use photographs and/or other images. They can make a sight more interesting and encourage visitors to participate by, for example leaving comments. Labelling an image with text can aid the screen reader user. For example a link to an article on dogs, rendered as a photograph of our four legged friend can be labelled as “dog” with the text stating that an image of a dog is included.

  1. CAPTCHA. CAPTCHA are those squiggly images, sometimes containing text which a computer user must interpret prior to being able to perform certain functions, for example submiting a contact form. They have the laudable objective of preventing spam however, in practice most CAPTCHA make it difficult (sometimes impossible) for blind computer users to contact the web master or comment on posts. This is because, as mentioned above, screen reading software like Jaws can not interpret images thereby rendering many CAPTCHA inaccessible. Some sites, for example Blogger do have an audio version of the CAPTCHA on which blind people can click. However this is, in my experience usually unintelligible, meaning that the visually impaired person gives up in frustration and fails to comment (I know I have been in that position many times)!

One of the reasons I like WordPress is due to it’s lack of CAPTCHA. WordPress uses Akismet (http://akismet.com/) which, in my experience captures well over 90 percent of spam without utilising CAPTCHA. As a blogger I do recognise the menace of spam. Spammers should be boiled in oil while hosts of bloggers dance around the flames. (that is, incidentally a joke before anyone takes me seriously)! However spam can be prevented very effectively without resorting to CAPTCHA and (accidentally) stopping blind people from participating on your site.

Many site owners take accessibility seriously and in the overwhelming majority of cases where accessibility issues exist this is due to a lack of knowledge (not out of lack of consideration for the needs of blind computer users).

Finally I would like to thank the many bloggers and others out there who take accessibility on board.

Robert

“They call him the new Tolstoy.

“A modern Dickens”, that is how one of the leading broad sheets referred to Mr A just the other day.

“Your latest novel, “The End Of The Beginning” shows such profundity. Really it took my breath away”, gushed Lisa Allingham-Carter, the host of “Books Are For Everyone”, smiling bewitchingly at Mr A. What does Ms Carter no about good literature? The daughter of a peer of the realm and the looks of a cat walk model, that’s what got her the job. I despair about the state of the arts in the UK. Heaven preserve us from the Allingham-Carters of the literary world!

You have to admire Mr A though. He began life on what the media has referred to as “surely the country’s roughest council estate” and now look at him, a mansion in the Cheshire countryside, not to mention the apartment in London’s fashionable Mayfair. Mr A has certainly arrived.

If only Mr A’s fawning fans new the truth. Whats that you ssay? No he doesn’t employ a ghost writer. Nothing so pedestrian for Mr A. Do I feel jealous? That’s an interesting question. I can comprehend jealousy at a purely intellectual level but, no I lack the capacity for such petty feelings.

I could develop the ability to be envious I suppose, for after all one can learn anything by rote. Let me tell you a story. You do have a few minutes to spare don’t you? Good, my tale won’t take long to relate I promise.

Once, not so very long ago there lived a man with aspirations to become an author. He longed to stand alongside the literary greats. To be mentioned in the same breath as Brontae, Dickens and Tolstoy was his dream. Sadly our friend lacked the ability to string a sentence together. His literary efforts where enough to make a cat laugh so to speak. Mr A did, however possess one quality which was to change the world of letters beyond all recognition, without anyone even knowing that society had, forever altered. You see Mr A was a brilliant computer programmer. You have heard of artificial intelligence? Of course you have. Well Mr A developed a programme capable of analysing the vast cannon of world literature. Drawing on the works of the literary greats, the software generated stories and poetry without Mr A lifting a finger (unless, of course you consider his setting the programme in motion as constituting literary effort).

The great advantage humans possess is that they, unlike software can venture out into the world. The writer overhears an interesting snipet of conversation while out shopping and incorporates that into his latest novel. Software can trawl the web but it can’t interact with people nor can it comprehend the myriad emotions which dwell within the human breast. Consequently for some time the software remained at an experimental stage (capable of producing stories but incapable of endowing it’s creations with the vitality that separates the mundane from the truly great).

The literary world has been shaken to it’s very foundations. Nothing can ever be the same again. Yet the world of letters remains blissfully unaware of me – Robert, the literary robot.

Dressed in jeans and t-shirt I don’t attract a second glance. I sit in bars, restaurants and other public places soaking up conversations. Sights, sounds and scents all go into my mamoth brain. Experience of the real world coupled with the knowledge gained from the internet makes me (err, I mean Mr A) a writer possessed of huge literary talent.

I could go to the media. Spill the beans I suppose but, as I’ve already mentioned human emotions such as envy aren’t part of my programming. It would though be interesting, on a purely cerebral level to upset the literary apple cart by announcing my presence to the world. I’ll think on that one. In the meantime I shall return to writing the sequel to “The End Of The beginning …”.

The Wanderer Returns

On 30 December I wrote a post entitled “Do Not Tempt Fate For She Will Always Have The Last Laugh”, (http://newauthoronline.com/2014/12/30/do-not-tempt-fate-for-she-will-always-have-the-last-laugh/). In it I described how the spilling of tea on my laptop had caused said item to migrate to the great IT heaven in the sky leaving yours truly virtually unable to use his trusty steed (sorry, laptop)! I am pleased to report that I now have a spanking new laptop keyboard thanks to PC Repairs Croydon, (http://www.pcrepairscroydon.com/). I took the ailing machine in on Saturday afternoon and picked it up today. I am delighted with the results – my laptop now works well. I will, however be keeping liquids of any description well out of harms way!

The gentleman who runs the business went beyond the call of duty. Not only did he fix my machine, he also helped me and my guide dog Trigger find our way back to the nearby station. In short the company provided a truly personal service and I would certainly recommend them.

The upside to not being able to blog (other than you all not having to read my posts)! Was that it enabled me to catch up with my reading. I am now just under halfway through Tolstoy’s Anna Karenina, (http://www.amazon.co.uk/Karenina-Translation-Carefully-Crafted-Classics%C2%AE-ebook/dp/B004JF4LCU) which I am greatly enjoying. While I wouldn’t recommend spilling te (or any other liquid for that matter on IT equipment) the unforeseen break did afford a welcome time for relaxation.

Over the next few days I will be catching up with all the posts I have missed so be warned I may well be dropping in on you with or without an invite!

Review of Kindle HD Fire 7

This review is of the Kindle Fire HD 7: http://www.amazon.co.uk/Fire-HD-Display-Wi-Fi-Black/dp/B00JXOXLP0
The Kindle Fire HD 7 allows the user to do far more than merely read books. The Fire also acts as a music player, enables the user to send and receive email, offers the ability to surf the web using Amazon’s Silk browser and perform many other tasks.
As a registered blind person I use the Fire’s text-to-speech facility which is of a very high quality. I do own an earlier version of the Kindle, however although this has a text to speech facility I am only able to read books with it (i.e. I cannot shop in the Amazon store or perform tasks other than reading). Consequently the Kindle Fire HD 7 is a good buy for people who are visually impaired, as they can shop Amazon on the device, (prior to me receiving the Kindle Fire as a Christmas present I had no option other than to purchase books and other items from Amazon using my computer, so the ability to shop using the device makes life much easier).
Although the device is very accessible, I do not like the on-screen keyboard as a light touch will activate a character meaning I, as a blind person cannot use it. I use an Apple Bluetooth keyboard which works well with the device.
Unfortunately Amazon’s Silk browser is only partially accessible to people with little or no vision. Amazon are aware of this and are looking into the issue.
My Kindle was purchased in John Lewis who offer an automatic 2 year guarantee with the Kindle, while Amazon’s guarantee is, I understand, only for 1 year. Consequently I would recommend that anyone thinking of purchasing a Kindle Fire HD 7 in the UK consider buying from John Lewis rather than Amazon.
I would recommend the Kindle HD 7.

Do Not Tempt Fate For She Will Always Have The Last Laugh

Do not tempt fate for she will always have the last laugh. This truism was brought home to me on 26 December when I wrote a post entitled “A Good Bath”. In it I described how I had spilled a cup of tea over my laptop’s keyboard. I then went on to poke fate most impolitely by suggesting that my machine appeared to have suffered no ill effects from it’s bath. Fate’s ire was roused and when I next attempted to log on to my laptop the machine’s keyboard refused to work, hence my silence between 27 December and today (30 December 2014).

I did write a post earlier today with the aid of a USB keyboard. However, Fate, still wrathfull owing to my tempting of her caused the laptop to behave erratically. The context menu kept popping up without rhyme or reason and I was forced to abandon my attempt. With due abeysance to the goddess Fate I trust that this post will, in fact go live. I am, incidentally drinking a cup of coffee as I write this with the aid of a USB keyboard (the laptop one being well and truly up the spout). The cup is, however on the carpet well out of harms way!

A Good Bath

If I should vanish from cyberspace, think only this of me, there is some corner of a Liverpool kitchen where tea should not be drunk while using a laptop …!

Yes I did what most computer users have done at some time or other – I knocked my drink over my laptop. Half a kitchen roll later the machine appears to be none the worse for it’s unexpected bath. I only hope that the tea is not, as I write reeking havoc in the inards of my machine. Well, if I ssuddenly disappear offline for a while you can make an educated guess as to why this has happened …! Fingers crossed that everything will come out in the wash so to speak …

The Pleasure Dome

I saw man lost in the lonely crowd. He saw not me but gazed in adoration at a shimmering screen. He prayed, fingers tapping incessantly, attempting to fill the void inside.

I saw family gathered around a flickering screen. Silence reigned for they feared to speak or, perhaps had nothing to say.

I saw Kubla’s stately pleasure dome but, instead of caves of ice, wires ran throughout that place.

I saw man lost in a virtual reality of his own device, and closed my eyes in holy dread,

For he on computer generated worlds had fed, and drunk the milk of paradise

Save, Save and Save Again!

Yesterday I breeched one of the cardinal rules of computing. I had taken the day off from the job which pays the bills (with my boss’s permission of course), With the aim of getting stuck in to some serious writing. Having treated myself to a healthy breakfast consisting of hash browns, bacon, sausages, eggs and beans (with several slices of tost just in case I faded away), I sat down at my laptop and began typing.

I worked merrily away, words populating virtual paper until, oops the machine froze. So intent had I been on my writing that I had neglected to save the document. The laptop, showing no immediate desire to behave itself, I took a deep breath and went to make a cup of tea. Fortunately the computer had, by the time I returned unfrozen allowing me to save my work.

I don’t know what caused the machine to freeze but suspect it may have been connected with Windows Update prompting me to install Microsoft’s latest updates. Whatever the cause I was lucky not to have lost the story I am working on – the lesson I draw is that work should be saved, on a regular basis to avoid hapless computers being thrown against walls by angry authors who, through their own forgetfulness have neglected to save their manuscript. I am pleased to report that my laptop has survived to drive me mad on a future occasion.
