Interesting article, but it has nothing to do with the title.

I don't think I agree with the title of the article, but it really didn't go
that direction.

> technical university there to leading a largely autonomous life in Silicon
> Valley, where he is a
> highly respected computer scientist and an engineer at Google.
> Along the way, Mr. Raman built a series of tools to help him take

> Mr. Raman, 43, is now working to modify the latest technological gadget

> for everyone. Instead of asking how something should work if a person
> cannot see, he says he prefers
> to ask, "How should something work when the user is not looking at the

> Such systems could prove useful for drivers or anyone else who could
> benefit from eyes-free access
> to a phone. They could also appeal to aging baby boomers with fading
> vision who want to keep using
> technology they've come to depend on.
> Mr. Raman's approach reflects a recognition that many innovations designed
> primarily for people with
> disabilities have benefited the broader public, said Larry Goldberg, who
> oversees the National
> Center for Accessible Media at WGBH, the public broadcasting station in
> Boston. They include curb
> cuts for wheelchairs, captions for television broadcasts and optical
> character-recognition
> technology, which was fine-tuned to create software that could read
> printed books aloud and is now
> used in many computer applications, he said.
> With no buttons to guide the fingers on its glassy surface, the
> touch-screen cellphone may seem a
> particularly daunting challenge. But Mr. Raman said that with the right
> tweaks, touch-screen
> phones - many of which already come equipped with GPS technology and a
> compass - could help blind

> "How much of a leap of faith does it take for you to realize that your
> phone could say, 'Walk
> straight and within 200 feet you'll get to the intersection of X and Y,' "
> Mr. Raman said. "This is
> entirely doable."
> ADVOCATES for the blind have long complained that technology companies
> have done a generally poor
> job of making their products accessible. The Web, while opening many
> opportunities for blind people,
> is still riddled with obstacles. And sophisticated screen-reader software,
> which turns documents and
> Web pages into synthesized speech, can cost more than $1,000. Even with a

> Last year, the National Federation of the Blind reached a settlement of a
> landmark class-action
> lawsuit against one company whose site advocates found unusable, Target.
> In the settlement, the
> retailer agreed to make its Web site accessible to blind people. The
> federation assesses the
> usability of Web sites and currently certifies only a handful as being
> fully accessible.
> One challenge is that technology often evolves much faster than the
> guidelines that ensure Web sites
> work well with screen readers. In December, the World Wide Web Consortium,
> an Internet standards
> group, released Version 2.0 of its accessibility guidelines for Web sites.
> The previous version
> dated back to 1999, when the Web consisted largely of static Web pages
> rather than interactive
> applications.
> Obstacles on the Web take many forms. A common one is the Captcha, a
> security feature consisting of
> a string of distorted letters and numbers that users are supposed to read
> and retype before they
> register for a new service or send e-mail. Few Web sites offer audio
> Captchas.
> Some pages are just poorly designed, like e-commerce sites where the
> "checkout" button is an image
> that isn't labeled so screen readers can find it.
> "The overwhelming percentage of the industry really hasn't stepped up to
> the plate to provide the
> blindness community with equal access to their products," said Eric
> Bridges, director of advocacy
> and governmental affairs at the American Council of the Blind. Mr. Bridges
> and other advocates argue
> that accessibility should be built into new technologies, not added as an
> afterthought.
> People with other disabilities face similar challenges on the Internet.
> "On the deafness side, the
> frustration is huge because of all of the video out there without
> captions," Mr. Goldberg said.
> MR. RAMAN, who before joining Google in 2005 worked at Adobe Systems and
> as a researcher at I.B.M.,
> is intimately familiar with accessibility problems, both personally and
> professionally. In 2006, he
> developed a version of Google's search engine that gives a slight
> preference to Web sites that work
> well with screen readers. The system had to test millions of Web pages.
> "You wouldn't have found a single page that fully complied with the
> accessibility guidelines," Mr.
> Raman said. Still, the system could detect which pages worked reasonably
> well with screen readers.
> The service is not being used as widely as he had hoped. Still, it has had
> an impact. Several Web
> site operators whose sites weren't showing up prominently in Google search
> results asked Mr. Raman
> how they could fix their sites so they would rank better.
> The service includes a screen magnifier that enlarges individual search
> results. Mr. Raman says the
> feature is intended to help low-vision users, but it could also prove
> useful to a much larger
> population, especially on cellphones and other devices with small screens.
> For his own use, he has built a highly customized system that allows him
> efficient access to much of
> what he needs on his PC and on the Web, stripping out anything that could
> slow him down. For
> instance, the system goes directly to the article text on the news sites
> he reads regularly,
> bypassing navigational links and other features found on most Web pages.
> On a recent day, Mr. Raman was working on a research paper about the
> future structure of the Web. A
> monitor hung above the desk. It is usually turned off, unless he wants to
> show a colleague or
> visitor what he is working on. He typed at his keyboard, his head slightly
> tilted to one side,
> listening to his screen reader through a pair of wireless headphones.
> The screen reader is calibrated to speak at roughly triple the speed of a
> normal voice. To the
> untrained ear, the output is incomprehensible, but it allows Mr. Raman to
> "read" at roughly the same
> speed as a sighted person.
> Processing information quickly is a skill he has developed over the years:
> a video on YouTube shows
> him solving his Braille Rubik's Cube in 23 seconds. When he is not typing,
> Mr. Raman, who wears
> large sunglasses, is often folding and unfolding pieces of paper into
> tiny, origami-like geometrical
> shapes at prodigious speed.
> He shares a work area at Google with Charles Chen, a 25-year-old engineer,
> and Hubbell, Mr. Raman's
> guide dog. (Hubbell has his own Web site.)
> Mr. Chen, who is sighted, developed a free screen reader for Web pages
> that works with the Firefox
> browser. Working together, the two recently added keyboard shortcuts that
> help blind and low-vision
> users navigate quickly through Google's search results. They've also
> developed tools to make
> sophisticated Web applications, like e-mail and blog readers, suitable for
> screen-reading software.
> Now, much of their effort is focused on touch-screen phones.
> "The thing I am most interested in is all of the stuff moving to the
> mobile world, because it is a
> big life-changer," Mr. Raman said.
> To show their progress, Mr. Raman pulled his T-Mobile G1, a touch-screen
> phone with Google's Android
> software, from a pocket of his jeans. He and Mr. Chen have already
> outfitted it with software that
> speaks much like a screen reader on a PC. Now they are working on ways to
> allow blind people, or
> anyone who is not looking at the screen, to enter text, numbers and
> commands.
> That development would complement voice-recognition systems, which are not
> always reliable and don't
> work well in noisy environments.
> Since he cannot precisely hit a button on a touch screen, Mr. Raman

> What may become the most life-changing mobile technology - a phone that

> benefit, too.
> "If you have the technology that can recognize a street sign as you drive

> Mr. Raman's innovations have already made their way onto millions of PCs.

> "It was incredibly important to us as a business, and to the blind," said
