“Is there anything a smartphone app can’t do?  Researchers at the University of Washington, UW Medicine and Seattle Children’s hospital have figured out how to let people measure their own lung health by breathing in the direction of the standard microphone on a smartphone, without any specialized attachments.

“Here’s the cool part:  The results from the app are within 5 percent of those from commercial spirometers that run into the thousands of dollars.  That level of accuracy means the app is already meeting medical standards.

“The app, called SpiroSmart, analyzes the sound waves from a strong exhale to judge the health of the person’s lungs.”

This New York Times article on modern robotics – largely focused on Rodney Brooks’s company Rethink Robotics – also discusses innovations by UW CSE’s Emo Todorov:

“In contrast to the fixed repetitive tasks performed by today’s robot arms and hands, scientists at the University of California, San Diego, and the University of Washington have built several prototype hands with pliable fingers that can move as quickly as humans’ …

“‘Despite decades of automation, there are relatively few types of tasks that have been automated,’ said Emanuel Todorov, a cognitive scientist at Washington.

“This is now changing rapidly as a new wave of manufacturing robots appears, driven by the collapsing cost of computing and the rapid emergence of inexpensive sensors that give robots new powers of vision and touch.”

“A recent survey of 1000 adults found a majority thought cloud computing actually referred to a “fluffy white thing.” Fifty-one percent also believed storms could interfere with it, according to the survey sponsored by Citrix.

“Those statistics are evidence that many computer users do not fully understand this new, important technology …

“‘Seattle is really ground zero for cloud computing with the presence of Amazon, founded here, Microsoft here and Google having a substantial presence here as well,’ said Bill Howe, a [UW CSE] professor.

“Thanks to the cloud, new companies no longer need to fill rooms with massive computer servers to store their data.

“‘We’re able to innovate in a way we’d never be able to innovate without using these cloud services,’ said Shauna Causey of Decide.com, a [UW CSE] Seattle startup.”

A New York Times article describing Rick Smolan’s forthcoming book The Human Face of Big Data features two of our favorite computer scientists:  UW CSE professor Shwetak Patel, and MIT EECS professor John Guttag:

“Mr. Smolan visited recently to offer a glimpse of what will be in The Human Face of Big Data and the imaginative photo composition involved in bringing technical subjects to life. One photograph shows Shwetak Patel, an assistant professor at the University of Washington, who has developed technology that measures energy and water use in homes; with wireless sensors and clever software to determine what appliances and gadgets in a home use the most electricity and water, the software suggests ways to conserve — information delivered graphically on an iPad. The photo shows young Mr. Patel in the backyard of his cousin’s house in Hayward, Calif., with his cousin’s family, surrounded by what looks to be every single appliance, digital device, faucet and toilet in the household.

“Another photo illustrates software technology that captures previously discarded data from heart-monitoring electrocardiogram machines. The software program sifts the data, looking for subtle heart abnormalities that identify patients that are at high risk of suffering a second heart attack within a year. The photo shows two M.I.T. scientists, John Guttag and Collin Stultz, who developed the technology, standing in a small mountain of paper, which is 10 hours of printout data from an E.K.G. machine.”

Today is UW CSE Ph.D. alum Geoff Voelker‘s birthday.  His UCSD CSE colleague (and fellow UW CSE Ph.D. alum) Stefan Savage writes:

Dear all,

Untold years ago today, our own Geoff Voelker was born.  Unfortunately, those of us who seek to communicate birthday wishes in the contemporary vernacular – a wry combination of “Happy Birthday” posts on the recipient’s Facebook “wall” and the “liking” of other such posts – are unable to do so in this case.  You see, Geoff is a practicing neo-luddite.  In particular, he shamelessly refuses to use any technology popularized after 1996.  Thus, he does not text, he does not tweet, he does not blog, pin, digg or tumbl.  He carries no portable electronics, his only phone plugs into the wall, he watches television via a broadcast cable and buys pre-recorded audio physically encoded on quaint pressed discs of aluminum and poly-carbonate. Webmail?  No way, this guy still reads direct from /var/spool/mail/  And… germane to this particular conversation… Geoff Voelker has no Facebook page and hence no wall.   

How then to wish Geoff “Happy Birthday”?  My first thought was to just create a Facebook account in Geoff’s name, thereby simplifying life for all of us.  Unfortunately, Geoff knows me too well and long ago extracted a solemn promise from me that I would not create, cause to be created or “allow to be created through inaction,” any account or page on the Facebook online social network.  Sealed in blood under a full moon, this is one of the few oaths that I’ve felt obligated to keep.   I needed another way.

Working tirelessly with a crack team of specialists, entrepreneurs, astrologers, lawyers, academics, and wild-eyed dreamers, we eventually found the loophole we needed.  Using arcane quantum mechanisms we arranged to shift the raw potentiality of Geoff’s Facebook page from the virtual online world, into an _actual_ Facebook page located in our physical plane of existence.  Through this solipsistic sleight of hand, Geoff now has a Facebook wall, appropriately located… on his wall.

Particular thanks go to alumnus Chris Kanich in our Great Lakes office for creating the page to exacting specifications, Neha Chachra for printing it, Dave Wargo for mounting it under glass and Kirill “the most interesting computer scientist in the world” Levchenko for his inestimable management skills.  

With that, I’d like to invite all of you who know and care for Geoff, to write your birthday wishes on his new Facebook wall in its physical location outside room 3108. Read more →

That’s six out of nine Ubicomp Best Paper Award nominees, including two of the three winners! Read more →

Steve Lohr in the New York Times:

“Technology tends to cascade into the marketplace in waves. Think of personal computers in the 1980s, the Internet in the 1990s and smartphones in the last five years.

“Computing may be on the cusp of another such wave. This one, many researchers and entrepreneurs say, will be based on smarter machines and software that will automate more tasks and help people make better decisions in business, science and government. And the technological building blocks, both hardware and software, are falling into place, stirring optimism.”
