From
Wired magazine:
The proliferation of touchscreen
technology may have revolutionized mobile computer input for most
everyone, but there’s one sector of the population that isn’t exactly
feeling the pinch, the tap, or the swipe: the blind. It’s nearly
impossible to interact with elements on a totally smooth screen if you
can’t see.
iBrailler Notes, which began as a summer project at Stanford University
in 2011 and is now available as a stand-alone app for iOS, aims to
offer blind and vision-impaired iPad users an easy way to type Braille
notes and perform basic word processing on a touchscreen.
iBrailler isn’t the first to undertake this commercially. There are a variety of apps
designed for the sight-handicapped, ranging from camera applications
that describe the content of an image aurally to other Braille-reading
and writing apps. Add to these the numerous accessibility features Apple offers on iOS, most notably VoiceOver, which reads text aloud to sight-impaired users, and its Braille QWERTY keyboard.
What iBrailler does differently is position its touch keyboard
underneath the user’s fingertips, no matter where they set them on the
iPad’s slick glass display. Every time you lift and readjust your hands
on the screen, the keyboard does too. The keyboard uses Braille English
Grade 1, Grade 2, and Six-Dot Computer Braille, and features built-in
gestures for tasks like cutting, copying, and pasting text.
More than 6.6 million Americans over the age of 16
are visually impaired, according to estimates by The National
Federation of the Blind. Much of that number are able to use computers
thanks to the tactile feedback of a keyboard, optionally with raised
Braille lettering on top, or a refreshing Braille display.
But a refreshing Braille display can be very expensive—thousands of
dollars per unit, according to Ed Summers, a blind computer scientist
with business analytics software firm SAS. A Braille keyboard is very
different from a QWERTY keyboard, he tells me: eight keys, one for each
dot that can compose a Braille letter, and a “display,” a strip of 18 to
80 Braille cells, each housing eight tiny pins that raise to form a
letter. Using this, a blind person can type on an iPad (or computer
screen), moving the cursor around, reading text, correcting spelling. A
small, 18-cell Braille keyboard can run around $1,800, while larger ones
can cost in the realm of $6,000.
Sohan Dharmarajah, one of iBrailler Notes’ creators, wanted to offer
the benefits of such a keyboard at a more affordable price. This iOS app
is a free download from the App Store, and users can subscribe for a small monthly fee if they like the experience and want additional features.
Summers thinks that an app like this could be incredibly useful,
particularly for students (he works with teachers of blind students in
addition to his science work). Historically, he says, visually impaired
students have had to use tools that make them stick out like a sore
thumb in class.
“Now they can use an iPad and they’re the cool kid,” he says. “They
have the coolest technology in the classroom.” Summers also notes that
this keyboard app could allow blind users to type incredibly quickly.
The app’s creators aren’t entirely sure how big the Braille iPad-user market is—certainly a growing number are used in education, and since the iPad was completely accessible to the blind from the get-go thanks to VoiceOver,
Apple fans of any sight ability have been able to use it just fine. But
actually typing out thoughts with your fingers, rather than dictating
with your voice, was still prohibitive.
Dharmarajah says feedback for iBrailler Notes thus far has been
overwhelmingly positive; the app is being used actively at several blind
schools and institutes in the United States and in Sri Lanka. An
Android version is also in the works and should be available soon.
