Giving Electronic Commands With Body Language
By ASHLEE VANCE NYT January 12, 2010
LAS VEGAS - The technology industry is going retro - moving away from remote
controls, mice and joysticks to something that arrives without batteries,
wires or a user manual.
controls, mice and joysticks to something that arrives without batteries,
wires or a user manual.
It's called a hand.
In the coming months, the likes of Microsoft, Hitachi and major PC makers
will begin selling devices that will allow people to flip channels on the TV
or move documents on a computer monitor with simple hand gestures. The
technology, one of the most significant changes to human-device interfaces
since the mouse appeared next to computers in the early 1980s, was being
shown in private sessions during the immense Consumer Electronics Show here
last week. Past attempts at similar technology have proved clunky and
disappointing.
In contrast, the latest crop of gesture-powered devices arrives with a
refreshing surprise: they actually work.

Manipulating the screen with the flick of the wrist will remind many people
of the 2002 film "Minority Report" in which Tom Cruise moves images and
documents around on futuristic computer screens with a few sweeping
gestures. The real-life technology will call for similar flair and some
subtlety. Stand in front of a TV armed with a gesture technology camera, and
you can turn on the set with a soft punch into the air. Flipping through
channels requires a twist of the hand, and raising the volume occurs with an
upward pat. If there is a photo on the screen, you can enlarge it by holding
your hands in the air and spreading them apart and shrink it by bringing
your hands back together as you would do with your fingers on a cellphone
touch screen.

The gesture revolution will go mainstream later this year when Microsoft
releases a new video game system known at this time as Project Natal. The
gaming system is Microsoft's attempt to one-up Nintendo's Wii.

Where the Wii requires hypersensitive hand-held controllers to translate
body motions into on-screen action, Microsoft's Natal will require nothing
more than the human body. Microsoft has demonstrated games like dodge ball
where people can jump, hurl balls at opponents and dart out of the way of
incoming balls using natural motions.
Other games have people contorting to fit through different shapes and
performing skateboard tricks.

Just as Microsoft's gaming system hits the market, so should TVs from
Hitachi in Japan that will let people turn on their screens, scan through
channels and change the volume on their sets with simple hand motions.
Laptops and other computers should also arrive later this year with built-in
cameras that can pick up similar gestures. Such technology could make
today's touch-screen tools obsolete as people use gestures to control, for
instance, the playback or fast-forward of a DVD.

To bring these gesture functions to life, device makers needed to conquer
what amounts to one of computer science's grand challenges.
Electronics had to see the world around them in fine detail through tiny
digital cameras. Such a task meant giving a TV, for example, a way to
identify people sitting on a couch and to recognize a certain hand wave as a
command and not a scratching of the nose.

Little things like the sun, room lights and people's annoying habit of doing
the unexpected stood as just some of the obstacles companies had to
overcome.

GestureTek, with offices in Silicon Valley and Ottawa, has spent a
quarter-century trying to perfect its technology and has enjoyed some
success. It helps TV weather people, museums and hotels create huge
interactive displays.

This past work, however, has relied on limited, standard cameras that
perceive the world in two dimensions. The major breakthrough with the latest
gesture technology comes through the use of cameras that see the world in
three dimensions, adding that crucial layer of depth perception that helps a
computer or TV recognize when someone tilts their hand forward or nods their
head.

Canesta, based in Sunnyvale, Calif., has spent 11 years developing chips to
power these types of 3-D cameras. In the early days, its products were much
larger than an entire desktop computer. Today, the chip takes up less space
than a fingernail. "We always had this grand vision of being able to control
electronics devices from a distance,"
said Cyrus Bamji, the chief technology officer at Canesta.
Competition in the gesture field has turned fierce as a result of the sudden
interest in the technology. In particular, Canesta and PrimeSense, a Tel
Aviv start-up, have fought to supply the 3-D chips in Microsoft's Natal
gaming system.

At last week's Consumer Electronics Show in Las Vegas, executives and
engineers from Canesta and GestureTek were encamped in suites at the Hilton
near the main conference show floor as they shuttled executives from Asian
electronics makers in and out of their rooms for secretive meetings.

Similarly, PrimeSense held invitation-only sessions at its tiny, walled-off
booth and forbade any photos or videos of its products.

In one demonstration, a camera using the PrimeSense chip could distinguish
among multiple people sitting on a couch and even tell the difference
between a person's jacket, shirt and under-shirt. And with such technology
it's impossible, try as you might, to lose your remote control.
