Gainesville, Fla. -- Always on,
connected, cheap and on sale everywhere.

What people have come to expect in cell phones and personal
communicators may soon become common in health-care devices and products
at home and in medical offices, thanks to new technology announced today
by the University of Florida and IBM.
The technology creates the first-ever roadmap for widespread commercial
development of “smart” devices that, for example, take a person’s blood
pressure, temperature or respiration rate the minute a person steps into
his or her house – then transmit it immediately and automatically to
doctors or family.
That could eliminate the need for many doctor’s visits, which are often
difficult for the elderly or sick. By enabling regular updates via text
message or e-mail, the technology also could pave the way for people to
share real-time information on their health or well-being with absent
loved ones. And it could prove useful for doctors who need to keep tabs on
many patients at one time by helping the doctors to prioritize whom to
treat first.
“We call it quality-of-life engineering,” said Sumi Helal, professor of
computer engineering and the project’s lead UF researcher. “It’s really a
change of mindset.”
The idea of using technology to provide medical care at a distance is
nothing new. Doctors have relied on “telemedicine” to communicate with
specialists for years. More recently, telemedicine has been expanded to
include, for example, surgeons performing robotic procedures on distant
patients.
But the UF-IBM advance goes a step further: It provides the
technological “stepstones” to make it easy for any company to manufacture
and sell smart networked devices -- while also making them more
user-friendly for consumers.
“UF and IBM both see the need and the opportunity to integrate the
physical world of sensors and other devices directly into enterprise
systems,” said Richard Bakalar, Chief Medical Officer for IBM. “Doing so
in an open environment will remove market inhibitors that impede
innovation in critical industries like health care and open a broader
device market that’s fueled by uninterrupted networking.”
Helal has devoted the past several years to developing smart devices
for the elderly in a model home known as the “Gator Tech Smart Home” in
Gainesville.
He and his students pioneered the “Smart Wave” microwave oven that can
automatically determine how much time to cook a frozen meal or keep track
of how much salt it contains. Among other devices, they also created an
instrument that records how many steps a person takes, information that
can tell absent caregivers how active its occupants are.
But these and other devices currently have a major shortcoming: They
require “a team of engineers” to install them, Helal said. In a world
where consumers are accustomed to electronics that require no more than a
power outlet, that dramatically limits their appeal. “We decided to create
a technology that self integrates,” Helal said. “When you bring it in to
the house and plug it in, it automatically provides its service and finds
a path to the outside world.”
With $60,000 in research funding from IBM, Helal designed “middleware,”
or software and hardware that glues together different systems, that can
give his and any similar health-aid devices this independence and
connectivity. Importantly, the software is based on open standards, or
publicly available specifications useable by anyone, such as those now
being made available by consortiums of technology companies including
Eclipse, W3C and OSGi.
Open standards make it easy for product developers to tap the
technology in any new smart assistive devices, Helal said. That, in turn,
will make the devices more common.
The hardware component of the system is an inexpensive sensor platform
about half the size of a business card. Developed at UF and licensed to
Pervasa, a Gainesville-based UF spinoff company headed by Helal, the
“Atlas” platform makes it easy to create a network of sensors and make
their information available on a computer network.
The advance is crucial given the increasing number of elderly
Americans. The number of people 85 and over is expected to rise from 4.2
million in 2000 to 6.1 million in 2010 and 9.6 million by 2030, according
to federal government statistics. Meanwhile, the percentage of older
Americans living alone will either remain high or continue to grow: About
half of women and nearly a quarter of men aged 75 and older currently live
alone.
But the UF-IBM technology may also prove useful in many other medical
settings. For example, Helal said, it could help emergency rooms operate
more safely. Rather than a standard waiting list, patients could be
equipped with networked wireless monitors of their vital signs, allowing
doctors to determine who in a waiting room needs the most immediate care.
