Anything stand out? Besides being an exemplary way to generate
excitement for what would become a revolutionary product, that ad, it
turns out, is a near-encyclopedic collection of every way you shouldn't be using an iPad (or any other tablet, for that matter).
Unfortunately, millions of consumers are already coming to the same
conclusion on their own — the hard way. While no hard numbers exist yet,
chiropractors, physical therapists and other physicians have taken to
referring to "iPad Neck" as a shorthand for the increasingly reported forms of upper body muscle and tendon injuries by their patients.
For ergonomics experts, there is a wicked irony in the fact that this
new generation of mobile devices — so seemingly full of potential to
finally liberate consumers from the shackles of body-contorting desktop
computing — are turning out to suffer the same fatal flaw as every
computing device before them: They're hell on people's bodies.
Jack Dennerlein,
adjunct professor of ergonomics and safety and director of the
Occupational Biomechanics and Ergonomics Laboratory at Harvard
University, said that the advent of tablet computing represents a step
backward of sorts. "We've gone back to books, is a way of thinking about
it," he said. That's meant as a compliment in that, unlike with desktop
and laptop computers, people are able to use tablets in an almost
infinite number of postures.
In theory, that means people ought to auto-adjust their bodies
frequently enough to avoid injuring ourselves — after all, nobody ever
went to the doctor for paperback thumb or hardcover elbow. Humans are a
funny bunch, though, and it seems their inclinations to adopt unhealthy
habits are far stickier than humble science could predict.
A Telling Story
Dennerlein headed up a study
last year in which veteran tablet users were observed while using
devices in various commonly adopted postures (tablet on a table, on a
lap with feet up, held while propped, etc.). Infrared sensors on the
subject revealed any potential injury-producing flexion of the head and
neck as subjects used the devices.
Dennerlein said that the overwhelming conclusion of his study wasn't
that any one posture was ideal or irredeemably bad. In fact, a seemingly
tangential factor turns out to be key. "The major finding of our study
was that the case used with a device is what really matters," he said.
"Different cases create different head angles for how people look at
these devices, but a lot didn't have what we call the 'Goldilocks angle'
— somewhere in between that's not too steep and not too shallow."
As such, Dennerlein is actually pro-tablet, especially when compared
with the other alternatives. "The problem with laptops is that nowadays
we get stuck working on them as a desktop replacement. So we're sitting
in the same spot for 8 hours," he said. "But with a tablet, you
shouldn't be sitting with them for long periods of time. They've given
us freedom to move around again."
Still, tablet neck is a real phenomenon, and so as with laptops and
desktops before them, users are obliged to adopt smart habits so they
don't end up with the dumbest type of nagging injury (you know, the ones
that are completely avoidable). Dennerlein stressed that there's no one
magical posture to ward off muscle strain, but offered the following
tips:
Tips for Safe Tablet Use
1. It's good to be restless
Sitting too long in any position is always inviting injury, as bodies
simply aren't meant to sit frozen for long periods of time. Muscles and
tendons need a break. As Dennerlein said: "The ideal posture is the next
one you're going to take," meaning the shift of position is everything.
If you're sitting in one position for more than a few minutes, that's
too long. "Think about it: Even when we sleep, we don't tend to stay in
the same posture for a very long time — we roll over and move in our
sleep," he said. "If you're feeling uncomfortable, listen to your body."
2. Don't believe Apple ads
Despite the temptation to kick back and prop your tablet on your lap as
you see in the early iPad ads, doing so typically requires one to adopt
unnatural neck angles or body contortions, forcing users to crane to
look down. Thus Dennerlein's one concrete no-no: "You can get away with a
tablet propped on crossed legs for maybe a couple minutes on the
subway, but any longer — you just don't want to."
3. Get a case
It's a good idea to opt for a case with a built-in stand
that allows you to position the screen at multiple viewing angles, so
that you can adjust it as needed. Dennerlein said a case propped on your
lap should ideally be at 45 degrees; when set on a table, it should be
more like 60 degrees (from flat). Dennerlein also pointed out that
recent 7-inch tablets are far lighter and easier to hold as you would a
book for a length of time, in lieu of a case.
4. Tablets aren't typewriters
It should be obvious, but tablets are way better for data and media
consumption than content generation. And so anyone boasting of their
blazing ability to Swype 80 words per minute is either lying or hiding
crippling fingertip bruises and blossoming carpal tunnel syndrome. The
fact is that besides being far more difficult than typing on a physical
keyboard, touch screens are almost always propped at a wrist-shredding
angle. And so Dennerlein is blunt: "Avoid typing anything more than an
email or two," he said. "If you're going to type the next 'War and
Peace' — just get an external keyboard."
5. Beware the glare
"There's two major factors when it comes to ergonomics: There's visual
access and support," Dennerlein said. "Those are the two things that
drive how people configure themselves when using a device." As such,
those highly reflective glossy displays that designers love so much are
an ergonomic nightmare, because they force users to subtly manipulate
their body away from a comfortably, neutral position in order to "fix"
their view. Dennerlein said it's a topic yet to be studied but that
users should be conscious of it. So again, invest in a case or stand
that allows you to prop your tablet away from glare so that you can sit
in a relaxed position.
