You're not about to replace your mouse, trackpad, keyboard or even
touch-screen as the chief ways to control your computer. But then you
start using the new Leap Motion Controller and -- at least in some
circumstances -- you can imagine relegating those other devices to the
bench.
Using the compact Leap Motion box, I was able reach out
into the open space in front of my computer and pluck a digital harp,
manipulate a three-dimensional rendering of molecular structures,
dissect a frog and — in the popular game of the same title -- Cut The Rope. I didn't make physical contact with the computer or any other devices.
Leap
Motion is a gesture-driven peripheral for PCs and Macs that I've been
fascinated with ever since the South By Southwest Interactive conference
in March where I had my first hands-on — nope, make that hands-above --
experience with the clever motion controller. Though my experience at
home with Leap Motion wasn't perfect, I'm no less intoxicated not only
by what it can already do but by what it promises to do in the future.
For
now, you can draw or paint with your fingers, mold 3-D objects, or
explore Google Earth through hand gestures. You can interact using
objects too.
Today, Leap Motion finally starts shipping to
customers who preordered it for $79.99, considerably cheaper than the
$249.99 Microsoft Kinect sensor that Leap Motion is inevitably compared
to. Leap Motion reaches Best Buy stores July 28. The controller was
originally supposed to ship in May.
The smallish (0.5 by 1.2. by
3-inch) rectangular unit plugs into the USB ports on a PC or Mac — both
long and short proprietary USB cables are supplied. Once in place, the
controller can detect even the subtlest hand and finger movements,
anywhere inside an interaction area that goes about two feet above the
controller, two feet out to either flank (150 degree angle) and a depth
of two feet on each side (120 degree angle). You can use multiple hands
and fingers, depending on the gestures required in the specific apps
that work with the controller. For that matter, another person can
stick their hands into this invisible cone of detection too and have the
computer respond provided the hands aren't somehow overlapping in
space.
Inside the controller are two camera sensors and a pair of
infrared LEDs, but the real wizardry arrives with the software. Leap
Motion claims an accuracy level of up to 1/100th of a millimeter, and
for the most part I found it responsive, though a couple of the apps
that work with it crashed in my tests on an iMac and at least one lagged
a bit. Figuring out and mastering the gestures within certain apps may
take some trial and error -- at times the interaction gets a bit
finicky.
You find compatible apps inside the aptly named Airspace
store. Many are free, though others fetch 99 cents on up. Leap Motion
has around 75 apps a modest but reasonably diverse sum. Some apps work
on PCs and Macs, some just on one platform or the other.
The
Airspace store is nicely laid out, with sections devoted to music &
entertainment apps, creative tools, science, education, productivity
& utilities, and other categories. In the "experimental" apps
section, you'll find Touchless for Mac and Touchless for Windows, free
apps that let you create a "virtual trackpad" in the air for interacting
with your computer. I tried the Mac version but didn't exactly excel
at it right away. As I wrote this review inside Microsoft Word, I was
able to scroll up or down by moving my entire hand towards the computer
screen with my hand and then raising it up or down but it was just as
easy to manipulate the trackpad the old fashion way. Through Touchless,
you can do a "click" gesture by pointing a single finger towards the
screen.
I didn't quite master the $2.99 Swoosh DJ app from a
developer called Just Add Music Media either. But I had a good time with
it anyway. Working in tandem with the music grooving inside iTunes,
Swoosh simulates a spinning vinyl disc. Through gestures and movements,
you can create reverb effects, or pause and restart a song. But for some
reason whenever I tried playing songs in iTunes after using Swoosh, the
volume within iTunes was turned all the way down.
I also had fun
trying out the $3.99 Frog Dissection simulation app from Emantras, which
lets you explore the inner organs of the amphibian wielding virtual
scissors, scalpels and forceps -- mercifully without formaldehyde or a
mess.
I can't say it is easier reading the New York Times
via their free Leap Motion app, than through more traditional methods.
In fact, you feel slightly silly twirling your fingers in the air to
navigate from one article to another, pointing and holding your finger
to select what to read, and drawing clockwise circles to scroll up or
counterclockwise circles to scroll down. And then when you're done
reading the piece, you shake your entire hand to escape, which also
isn't natural.
For now, you'll need the Leap Motion controller
itself to exploit the company's technology. But Leap Motion has struck
deals with Asus and Hewlett-Packard to embed 3-D motion control into
machines from those computer makers.
During South by Southwest,
Leap Motion marketing vice president Michael Zagorsek told me that the
company hoped to make the user interface disappear altogether. "I'm not
clicking on something to do something else, I'm not touching something
to do something else. There is no interface, it's just me represented
here," Zagorsek said.
To be sure, you'll still rely on the mouse and keyboard most of the time. But with Leap Motion you won't always have to.
