Your eyes are absorbing this webpage . They ’re pass over this , this , then this word , right now . That ’s how reading works , online : you take this for award . But what if you could n’t ?
We grant our gaze to electronic blind for most of the day , and in issue , they give us anything we want . We stare ; they radiate . We seldom verbalize , and neither do they .
And this have signified ! The net is a limitless aggregation of text , images and video , channeled to bland musical composition of deoxyephedrine and plastic , beamed through lens , retina , and cheek , all the way into our brains . It can show us anything , and for most WWW exploiter , that ’s exactly what it does .
But for meg of others — those who are ineffective to see — the web is a wildly different place . Characters become sounds . layout are nonmeaningful . image are , at best , words , and at worst , blank spaces . And yet the blind browsing the same net as everyone else , every day . They use the same widget the sighted do , and happily . But how ?
The Sightless Internet
The most common way for the visual sense - mar drug user to get at the internet is with a traditional web web browser and school text - to - speech software . You ’re probably already vaguely intimate with some of it — Windows users will have come across Microsoft Narrator , and I defy you to find a individual Mac OS user who has n’t forced VoiceOver to hurl insults at his friends . It ’s these tools — or tools like these — that millions of people look on to get to the cyberspace .
But to say that unreasoning user just “ hear ” the internet is a gross simplism . It ’s not just text and image that unsighted users miss , it ’s about every part of the fundamental browsing experience .
Here , assay this : Stop reading for a moment . Lean back and survey this varlet . Now think about what you do when you visit this site . You eyes are probably draw to the stories name horizontally across the top of the page . They wait important , correct ? Why else would they be up there ? Further down you ’ll see the site ’s banner , but you belike do n’t expend much clock time looking at that , and your eyes dart to the list of tarradiddle in the centre of the page . You scroll down , glancing at pictures then headlines , or perhaps headlines then word picture . The border of the website are either full of ads or unchanging information , so you in all likelihood do n’t pay them much mind . Now strain somewhere else , somewhere morevisually complicated . retrieve about how you ’re reading it .
Your habits are n’t just sight - dependent ( apparently ) , they ’re passably weird . Your eyes fly around , sometimes randomly and sometimes in reply to cues onscreen . You hunt for links and cherrypick from galleries . The news you ’re appear for catches your center , so you click it . Consciously or subconsciously , you usually lie with where to look .
With a screen reader , there is no “ face . ” It ’s a wide-eyed parser , and it commence at the top . It comb through a website a lot like a web browser app combs through HTML , except instead of rendering an IMG tag as an image , or an EM tag end as italicize text edition , it convert them to sounds : a read-out of the image description — the alt textbook — and a changed audio inflection , respectively .
Then , of course , there ’s all that text . On a visually rendered web page , it live in block and tower . If you ’re favourable , these blocks and chromatography column will be organized in a logical or intimate manner . They ’ll be laid out , basically . But that ’s such a optic concept . What bump when a layout becomes words ?
“ Screen meter reading software presents the webpage as a set of stemma and link , and possibly other things — frames and cope , if the software employ that . ” That ’s Paul Schroeder , VP of Programs and Policy for theAmerican Foundation for the Blind . Vision - impaired himself , he uses screenland reading software system for daily browsing . “ When you log onto a website using screen reading software , what you start with is a internet site that tell you how many lines , and some basic anatomical structure — but not very much . When you ’re get a littered website , the information you want may be 300 - 400 lines in , and if you ’re fail argumentation by line , or section by section , it can take you a very retentive time to discover what you want . ”
Think about that : The internet is anything but linear — website code is nested and sibylline , and often looks disorderly and out of Holy Order . ( Right sink in , see source ! Oh , yikes , maybe do n’t . ) internet site often have multiple ocular directions , or sometimes none at all . Yet audio sieve reader — and Braille module , which expose about one line of text at a time — have to render them in sequence , somehow . And listeners have to make good sense of it , to produce some kind of intuition for a site ’s layout and structure based on very , very small measure of data , all out of order .
Of of course there are tricks . Screen reading software , like VoiceOver in OS X or jaw for Windows , is more apt than I ’ve made it sound . It parses site for headers , and sometimes navigational elements . It can give you a actual description of a pageboy ’s layout—”three columns , two rows”—and its surprisingly unrobotic voices reflect all sort of punctuation . It even differentiates between outwardly identical tags . My editor actually just sent us an email to this effect : cease using < EM > and < I > dog interchangeably . One is for italics , and one is for emphasis . It ’s a difference you ca n’t see , but it ’s a difference some will hear .
These are the small feature that make verbalize webpages operable , but they ca n’t be taken for granted : mass who plan websites have to be wakeful about include header to carve up large blocks of schoolbook , to include alternative schoolbook for images , and to use their tags decent . Problem is , a whole net ton of sites — ours included — often do n’t . Ever had — or overhear — a windy argumentation about whether or not a site is “ standard compliant ” , as inW3C , HTML compliant?Well , this is like that . in reality , this is that . The W3C defines standards for availability just like they define standards for therest of the web . But like those other standards , they ’re often brush aside .

And even a totally compliant website can be overly complicated , or just too smooth . “ Facebook is a undecomposed case , because it ’s an ever - changing surroundings , ” says Schroeder . “ Some users control particular aspects of Facebook , encounter that the computer programing has changed , and have to rethink their scheme . ” But again , there are tricks : “ Vision - vitiate exploiter who frequent Facebook and similar website do one of two things : They either use the mobile interpretation of the site , which is less cluttered , or they only hire the specific thing they want to do and remember the specific thing they want . ”
by rights code site , sound software , and handy shortcuts and whoremaster mesh together to make browse the web tolerable for the visual sensation impaired . Skills and persistence act as a big part too . Schroeder assure me that in some case , blind substance abuser can skip through site header and run searches so quickly that they may be more efficient than sighted user in some state of affairs .
But pendinglegislationcould leave us with a much broader interpretation of the American With Disabilities act , which could mandate sure commercials websites to do those small affair that make screen - reading easier . But it ’s a constant struggle , with engineering science often outpacing the shaft necessary to parse them . Oh , and I almost forgot , the web is dead . Or something .
Gadgets ‘n’ Apps
In case you missed last calendar month ’s wire covert story , hereit is . The effect , to savagely oversimplify the piece , is that the web as we know it , this conversant hodgepodge of websites rendered in browsers — you have it off , the W3C ’s standard - based web — is falling out of style , take in way for the newfangled internet : the internet of apps .
I do n’t totally buy it , but that ’s not the full point . Apps are everywhere , and so are the twist that run them . I read as much on my mobile devices as I do on my laptop computer , if not more . So if the time to come function on an iPad , what does that mean for the guy who ca n’t see ?
It ’s really a two - part head , so let ’s start with the fun half . The raise of the touchscreen gadgets , 2-dimensional , featureless panels they are , is in reality great news for blind folks . lease me put that another mode : If you ’re unable to see , the iPhone , with its virtual buttons and complete lack of tactile feedback , is actually gentle to use than , say , a BlackBerry , with its dozens of buttons . uncanny ! Well , not really .
Part of the chronicle here is software package . iPhones ( and now Android phone ) have sophisticated textbook - to - spoken language functionality , without which they ’d be useless to the vision - afflicted . BlackBerry phones , on the other hired man , basically do n’t .
But even if RIM put out an update to all their button - based phones giving them flawless screen - reading abilities , they could n’t quantify up to a touchscreen gadget .
When you utilise a BlackBerry ( or a Mac , or a PC ) your sense of piazza is delimit by sight . You move with a cursor , or a highlight menu item . Then you click . And for the same reason web layouts are n’t very helpful to a unreasoning person , the cursor paradigm — hell , the whole push button - input paradigm — give suck . With a touchscreen , though , your fingers allow your common sense of berth . iPhone substance abuser can turn over on the VoiceOver function , tap anywhere , and discover a narration of what ’s hap . Tap the upper left section of your screen , right near the volume switches , and a voice might read , “ Camera app . ” Tap the bottom left , and you ’ll pick up “ Phone . ” With buttons , mouse and keyboard , you ’re lodge back in that dull , analogue screen - reading worldly concern . With touchscreens , a screen , and a spell of software , can in reality be follow . memorise . Used .
So that ’s pretty neat . But it ’s a rosy take . Asked about smartphones , Schroeder painted a glum delineation : Apple and Google may be doing this stuff the right way , and progress self-colored text - to - manner of speaking into their operating systems , but other companies are lagging . And anyway , text - to - speech in an oxygen is capital , but today ’s smartphones are all about apps , prepare by thousands of masses in thousands of configuration . On the iPhone , for example , some apps crop dead with VoiceOver . Plenty more do n’t .
Messy as it is , the capital “ W ” vane seems to be inching closer to world-wide accessibility . It has a guidebook , at lower limit . But all these apps , and all their storage , may be set progress back a few days . Suddenly , blind users ’ experience is at the mercifulness of each single app developer , or with any luck , companies that supply their tools , and grant them access to their app stores . It ’s not an insurmountable problem , but it ’s a problem .
In any case , whether you ’re an app developer , entanglement designer or just a dude who likes to update his blog every once in a while , remember that someone , somewhere , might be listening to what you ’ve written . And that alt texts in images are n’t just forjokes . And that it ’s still OK to force your computer to recite profanities to you acquaintance , for bitch .
