IBM, University of Florida team up on smart devices

IBM and the University of Florida believe they've come up with middleware that will allow doctors to remotely monitor the health of their patients.

The technology makes it possible for standard wired or wireless devices, such as blood-pressure and glucose monitors, to be reconfigured so that when used by patients at home the devices can automatically send the collected readings to healthcare professionals.

IBM and the university have been working on the smart-device project for the past 12 to 15 months and have produced a short video to illustrate its possible use. In the video, an elderly man called Charley requires twice weekly visits to his doctor to check his blood pressure. He's able to cut down on the number of those visits by taking his readings at home using a monitor that's been reconfigured with the middleware.

The value of the technology is what could be achieved with it by any device manufacturer, said Sumi Helal, professor of computer and information science and engineering at the University of Florida, who headed the project.

The technology is a combination of middleware software and sensor hardware called Atlas from University of Florida spin-off Pervasa.

Should the technology be adopted, Helal would expect to see smart devices on the market within the next one to two years. It would then be possible to buy a device off the shelf and by dialing a 1-800 phone number establish a connection between the device and one's doctor. "The device itself becomes a service," he said.

Much of the work on developing Web services around a service-oriented architecture has been looking at how to exchange information between people when neither party is familiar with how the other's IT system was built. There's been plenty of SOA work to Web-enable legacy mainframe systems. "What's the ultimate legacy system for us? The human body," said Bob Sutor, vice president of standards and open source at IBM.

The security governing the devices would be the same as that used in online banking, Helal said. It's possible to make that security very finely grained, Sutor added, to encrypt particularly sensitive fields.

It will be up to device manufacturers to ensure that their products are tamperproof to avoid the possibility of false readings, Helal said.

As a way to start building momentum behind the technology, IBM has contributed components of the project to the Open Health Care Framework of the Eclipse Foundation, a community that develops open source tools.

Being able to continuously collect information and monitor patients can help build up a more complete health history for an individual, which can then be accessed not only by their doctor but also by first responders should the person experience a medical emergency. Such devices could also be useful in hospitals as patients wait to be seen. If patients are wearing the devices, healthcare professionals could more easily see from their readings that individual requires immediate attention, Helal said.

The ability to take a large number of readings can be particularly helpful as a patient gets used to a new medical device, say an insulin pump, which might require lots of fine tuning to find the right dose of insulin for the individual, Sutor added.
