Pi-powered jacket wraps you in a personal cloud
Cloud computing can be a nebulous and worrying concept for some
people, with their data flying off into a server somewhere in the world.
Now computer engineers from the University of Alabama at Birmingham
(UAB) have developed a prototype that aims to keep the cloud local by
wrapping it around the user in the form of a microcomputer-embedded
jacket.
Developed by Ragib Hasan and Rasib
Khan at UAB, the prototype has 10 Raspberry Pis for its brain, along
with three power banks and a remote touchscreen input. The idea,
according to its creators, is to better connect all of a user's devices,
and outsource the computing power and storage to the cloud jacket,
meaning individual devices can be "dumber" and therefore less expensive.
"Currently if you want to have a smart watch, smartphone,
an exercise tracker and smart glasses, you have to buy individual
expensive devices that aren't working together," Hasan said. "Why not
have a computational platform with you that can support many forms of
mobile and wearable devices? Then all of these capabilities can become
really inexpensive."
The Raspberry Pi-flavored cloud gives the
jacket about 10 GB of RAM and a total of 320 GB of storage space, making
it much more powerful than any smartphone around today. With that much
power under the (possibly literal) hood, the cloud jacket would enable
phones, watches, tablets and other smart devices to simply act as input
controllers, connected to the jacket via Bluetooth or Wi-Fi.
When
the wearer opens or uses an app, the cloud jacket does the heavy
lifting, then streams the data back to the device. And with their own
private, wearable network, most or all of their personal data stays on
their person.
"Once you have turned everything else into a 'dumb
device,' the wearable cloud becomes the smart one," says Hasan. "The
application paradigm becomes much more simple and brings everything
together. Instead of individual solutions, now you have everything as a
composite solution."
It's not just limited to a jacket, either.
The personal portable cloud concept could take as many forms as an
actual cloud, embedded into other items of clothing, briefcases, purses,
backpacks, or anything else people carry around everyday.
Other
applications are being explored, too. Hospital patients could wear a
comfortable jacket that syncs to an array of monitors, rather than being
physically wired in. Personal clouds could even sync up to form a
network for first responders or soldiers to communicate and share data.
"With
seven to 10 people wearing such a cloud together, they create what we
call a hyper-cloud, a much more powerful engine," says Hasan. "The
jacket can also act as a micro or picocell tower. All of its
capabilities can be shared on a private network with other devices via
Wi-Fi or Bluetooth. If a first responder is out in the field and doesn't
have complete information to act on a mission, but someone else does,
it can be shared and updated through the cloud in real time."
The research paper was published through the SECRET Lab,
at UAB's Computer and Information Sciences department and Hasan and
Khan presented their concept and a prototype wearable cloud jacket at
the 40th Institute of Electrical and Electronics Engineers Computer
Society International Conference on Computers, Software &
Applications (IEEE COMPSAC) in June.
