HAGENT - The Black Box That Searches For Heat


HAGENT - Presentation Charts - Daniel Abendroth & Andreas Meinhardt - Prix Émile Hermès

Andreas Meinhardt and Daniel Abendroth show in this video the idea, the concept, the application, the technical background and the prototype of HAGENT.
The Black Box searches for heat with thermal senses. It can indentify and absorbe the surplus energy from heat emitting sources. It stores, moves and releases the energy on places where the heat is needed.

This video is based on the presentation charts of the entry documents that has been submitted to the design competition.

HAGENT - Entry video for Prix Émile Hermès - Daniel Abendroth & Andreas Meinhardt

Andreas Meinhardt and Daniel Abendroth show in this video the basic idea of HAGENT.
The Black Box searches for heat with thermal senses. It can indentify and absorbe the surplus energy from heat emitting sources. It stores, moves and releases the energy on places where the heat is needed.

This video was added as an optional part to the entry documents that has been submitted to the design competition. It is the more entertaining version of the HAGENT concept. The footage was taken around Stuttgart in January 2011

HAGENT - Prototype Part1- Daniel Abendroth & Andreas Meinhardt - Prix Émile Hermès

Andreas Meinhardt and Daniel Abendroth show in this video the first part of the development of HAGENT. The simple mockup is based on a plywood frame and a control unit borrowd from a modified Segway. It just controls the speed of the wheels. As you see the lack of sensors causes a lot of fun.

The final prototype was exhibited at Les Arts Décoratifs in Paris Oktober 2011
Daniel Abendroth & Andreas Meinhardt received for HAGENT the 2nd Prize from the Fondation d'Enterprise Hermès in the International Design Competition of Prix Émile Hermès 2011.

HAGENT - Prototype Part2- Daniel Abendroth & Andreas Meinhardt - Prix Émile Hermès

Andreas Meinhardt and Daniel Abendroth show in this video the 2nd part of the development of HAGENT. The Ultrasonic sensors and a new control unit were added to the basic mokup. Now HAGENT is able to move autonomously and can detect and prevent collisions.

HAGENT - Prototype Part3- Daniel Abendroth & Andreas Meinhardt - Prix Émile Hermès

This is the 3rd part of the development of HAGENT. The thermal sensor is separated from the system. Daniel and Andreas are playing "Heat detection" with a Hot Air Gun. In addtion they are testing sensor activity while covered with textiles. First ideas to detect bodyheat have been rejected after they found out that there are so many heat emitters within this temperature range (sun reflections, Monitors, machines...). Because they wanted to have a more predictable test set up they decided to raise temperature sensivity up to 140°C and test the movements with infrared lamps.

HAGENT - Prototype Part4- Daniel Abendroth & Andreas Meinhardt - Prix Émile Hermès

This is the 4th part of the development of HAGENT. Final adjustments and finishing were made to the completed prototype. Of course this was done till early in the morning before heading to Paris and deliver the prototype at the Fondation d'Enterprise Hermès :)

Hagent: Renderings - Images - Photos - Grafics


HAGENT - Prix Émile Hermès - Rendering - Phase change materials - Daniel Abendroth

PCM - Phase change materials are already used in static building parts for climatisation of passive houses. Their basic function is to substitute the heat storage capacity of massive building construction parts. Over a certain temperature level the PCM absorbs heat whilst changing its physical condition. If the air temperature drops under the threshold the PCM releases the heat whilst regaining its original physical state. And as they are also more lightweight their usage is predestined for mobile appliances.

NASA's Technology Roadmap

RELEASE : 12-039

NASA Receives Final NRC Report On Space Technology Roadmaps

WASHINGTON -- NASA has received the National Research Council (NRC) report "NASA Space Technology Roadmaps and Priorities," which provides the agency with findings and recommendations on where best to invest in technologies needed to enable NASA's future missions in space. The NRC report will help define NASA's technology development priorities in the years to come.

One year ago, NASA provided 14 draft space technology area roadmaps to the NRC and asked the council to examine and prioritize technologies for the agency. The technologies were prioritized in each of the 14 areas and then across all categories.

The report finalizes the NRC's review and identifies 16 top-priority technologies necessary for NASA's future missions, which also could benefit American aerospace industries and the nation. The 16 were chosen by the NRC from its own ranking of 83 high-priority technologies out of approximately 300 identified in the roadmaps.


"The report strongly reaffirms the vital importance of technology development to enable the agency's future missions and grow the nation's new technology economy," said Mason Peck, chief technologist at NASA Headquarters in Washington. "The report confirms the value of our technology development strategy to date. NASA currently invests in all of the highest-priority technologies and will study the report and adjust its investment portfolio as needed."

The technology priorities the report identifies are aligned with NASA missions to extend and sustain human activities beyond low Earth orbit, explore the evolution of the solar system and the potential for life elsewhere, and expand our un¬derstanding of Earth and the universe in which we live.

The report observes that "technological breakthroughs have been the foundation of virtually every NASA success. In addition, technological advances have yielded benefits far beyond space itself in down-to-Earth applications." It also states "future U.S. leadership in space requires a foundation of sustained technology advances."

During the coming months, NASA's Office of the Chief Technologist will lead an agency-wide analysis and coordination effort to update the 14 technology area roadmaps with the NRC report's findings and recommendations.

New Study Reveals Student Perspective on Technology Use in Higher Education

By Kanoe Namahoe
10/03/11

College students believe that technology has a direct impact on their academic performance, according to findings from a new student-driven study out of the Lone Star College System. In “The National Lone Star Report on Aligning Technology with Student Success,” 78 percent of college students reported that their grades and learning experience are improved when technology is effectively and consistently implemented on their campus.

The Report is a compilation of survey data collected from more than 6,000 students on 36 campuses across the country. Focused exclusively on two-year colleges, the study also included analysis of more than 1.5 million helpdesk inquiries from 55 institutions. The student-led initiative is the first of its kind, according to LSCS vice chancellor and CIO Shah Ardalan.

"'The National Lone Star Report on Aligning Technology with Student Success' will allow college administrators access to the collective voice of American students and it provides invaluable data on students' needs, desires and dreams, and how technology can help them achieve these goals," Ardalan said in a prepared statement.

Key findings in the report reflect students' desire for reliable, effective technology that is used consistently by instructors:
Colleges should not implement technology for the sake of technology;
When technology is deployed, make sure that it works; and
Faculty members need to know how to use the technology and they should actually use it.

While students believe technology is integral to their learning success, the report showed that they do not simply want more technology--they want the right technology. Students want systems and applications that serve their needs, support learning, and work properly "without getting in the way." Students expressed frustration with non-working technologies that waste time and money.

"Technology, when effectively used, strongly impact[s] my ability to learn," one respondent noted. "However, when it is not used properly or [is used] inefficiently it is very much a distraction and annoyance."

The National Lone Star Report was based on interviews and surveys from students at rural and metro-area community college campuses throughout the United States. The report will be produced annually and is available for free download to participating colleges. For additional information, visit lonestar.edu/nationalstudentreport.

The 2010 Campus Computing Survey

EDUCAUSE Conference Video 

IT Budget Cuts Slowing;Campus LMS Strategies in Transition

The budget cuts that have wrecked havoc on college and university IT units and resources in recent years may be abating: new data from institutions participating in the annual Campus Computing Survey reveal that two-fifths (41.6 percent) of colleges and universities reported a budget cut in central IT services for the current academic year, down from fully half (50.0 percent) in fall 2009. Private/non-profit institutions fared better than their public counterparts: the proportion of private universities reporting IT budget cuts fell by more than half, from 56.9 percent in 2009 to 24.4 percent in 2010. Among private four-year colleges, the percentage reporting budget cuts fell from 41.9 percent last year to 31.9 percent this fall.

Although the percentage of public four-year colleges and universities reporting budget cuts also declined compared to 2009, the number went up for community colleges. Almost half (46.2 percent) of the community colleges participating in the 2010 survey reported budget reductions affecting central IT services, compared to 38.0 percent in 2009. In contrast, fewer public universities suffered IT budget this year than last (59.8 percent in 2010 vs. 67.1 percent in 2009), as did fewer public four-year colleges (46.6 percent this fall compared to 62.8 percent in 2009).

“The new survey data provide a modicum of good news about money: fewer institutions experienced budget reductions this year than last,” says Kenneth C. Green, founding director of The Campus Computing Project, the largest continuing study of computing, eLearning, and information technology in American higher education. “But the on-going financial pressures confronting campus IT budgets continue to play havoc with the efforts of campus IT leaders to respond to the rising demand for IT resources and services, and the concurrent the need to invest in the campus IT infrastructure.” Green notes that the current round of budget reductions arrived just as campus IT units were just beginning to recover from the major budget cuts that came early in the decade. “No question that these budget cuts have affected instructional resources, and IT support services for students and faculty, and efforts to invest in the campus IT infrastructure.”

The 2010 survey data highlight the continuing transition in the higher education market for Learning Management Systems (LMS). The proportion of survey participants reporting that their institution uses Blackboard as the campus-standard LMS has dropped from to 71.0 percent in 2006 to 57.1 percent in 2010. Concurrently, Blackboard’s major LMS competitors have all gained share during this period. The percentage of campuses that use Desire2Learn as the campus-standard LMS is up five-fold, from 2.0 percent in 2006 to 10.1 percent in 2010. Moodle, an Open Source LMS, also registered big gains during this period, rising from 4.2 percent in 2006 to 16.4 percent in fall 2010 The numbers for Sakai, another Open Source LMS deployed primarily in research universities, have grown from 3.0 percent in 2006 to 4.6 percent in 2010.

“The LMS market is a textbook example of a mature market with immature, or evolving, technologies, and that’s a prescription for a volatile market,” says Green. “Blackboard’s announced plans to terminate support for its legacy LMS products have been a catalyst for many institutions to review the campus LMS strategy and to evaluate other LMS applications. This is now a competitive market and Blackboard’s major competitors are Desire2Learn, Moodle, and Sakai. All three have slowly but steadily gained attention, campus credibility, and market share in the past three years.”

Linked to the campus LMS strategy, more than two-thirds (70.3 percent) of the survey participants agree/strongly agree that “mobile [LMS] apps are an important part of our campus plan to enhance instructional resources and campus services.” However, the survey data indicate that mobile apps are in the early phase of campus deployment: as of fall 2010, a little more than an eighth (13.1 percent) of campuses have activated mobile apps; another tenth (10.1 percent) report that mobile apps are scheduled to go live at their institutions this current academic year (2010-11), while a quarter (24.8 percent) report that mobile apps are currently being reviewed by their institution.

"The campus interest in and movement to mobile apps reflects trends in the consumer market,” says Green. He cites data from Student Monitor’s spring 2010 survey of full-time undergraduates in four-year colleges indicating that 98 percent of students own cell phones and almost half have smart phones: “students expect their institutions to provide the kinds of resources and services they experience and enjoy as consumers. Mobile apps provide online access to instructional resources and campus services from the buttons on your smart phone.”

Also in the realm on instructional resources and services, fully three-fifths (60.5 percent) of the survey participants agree/strongly agree that “lecture capture is an important part of our campus plan for developing and delivering instructional content.” As with mobile apps, lecture capture is in the early phase of what will likely be widespread campus deployment: as of fall 2010, just 4.4 percent of courses make use of lecture capture technologies, up from 3.1 percent in fall 2008.

The survey data reveal that student activities on social networks can pose social problems for colleges and universities. Almost a sixth (15.4 percent) of campuses participating in the 2010 survey report a past year “incident” (cyberstalking; cyberbulling, etc.) linked to student activity on social networking sites this past year, up from less than a tenth (8.6 percent in 2006). Moreover, the proportion of campuses reporting incidents linked to social networking sites jumped dramatically in some sectors this past year, rising from 15.8 percent in 2009 to 27.3 percent in public universities and up from 13.6 percent to 20.8 percent in public four-year colleges.

“These rising numbers suggest it will be difficult for college and university officials to ignore the campus consequences of student behavior on social networks,” says Green. “Although Facebook and other social networks are not supported or sponsored by colleges and universities, the activities of individual students on these sites can have consequences for other students and for their institutions. Many campuses are likely to expand their user education initiatives as part of institutional efforts to address this issue.”
Senior campus IT officers appear bullish on the future of eBooks. Well over four-fifths (86.5 percent) agree or strongly agree that “eBook content will be an important source for instructional resources in five years,” up from 76.3 percent in 2009. Additionally, more than three-fourths (78.6 percent, up from 66.0 percent in2009) agree/strongly agree that “eBook readers (hardware) will be important platforms for instructional content in five years.”
“eBooks remain a much wished for, ‘ever-arriving’ technology in academe,” says Green. “The platform options, market opportunities, and enabling technologies for eBooks continue to improve.” But Green notes that for most students, eBooks and eTextbooks do not yet offer competitive alternative to used textbooks. “eTextbook development and pricing strategies are still evolving. Publishers still develop titles primarily for print, and then port print content into electronic formats. Consequently, eBooks and eTextbooks do not - yet - provide a compelling value proposition for most college students.”

The 2010 Campus Computing Survey is based on survey data provided by senior campus IT officials, typically, the CIO, CTO, or other senior campus IT officer, representing 523 two- and four-year public and private/non-profit colleges and universities across the United States. Survey respondents completed the questionnaire September and early October 2010. Copies of the 2010 Campus Computing Survey will be available on December 10th from the Campus Computing Project in Encino, CA (campuscomputing.net). Price: $37, plus $2 shipping.

Silicon Valley Wows Educators, and Woos Them


Craig Lassig for The New York Times
GRADING THE DIGITAL SCHOOL

Silicon Valley Wows Educators, and Woos Them

 at Little Falls Community High School in Minnesota trying out some iPad apps.

In visits the officials described as inspirational, they checked out the company’s latest gadgets, discussed the instructional value of computers with high-level Apple executives and engineers, and dined with them and other educators at trendy restaurants. Apple paid for meals and their stay at a nearby inn.SAN FRANCISCO — Three times over the last two years, school officials from Little Falls, Minn., have escaped the winter cold for two-day trips to Silicon Valley. Their destination: the headquarters ofApple.
The visits paid off for Apple too — to the tune of $1.2 million in sales. In September, Little Falls handed out iPads to 1,700 of its 2,500 students at a celebration in the school gym. And a few days earlier, 200 teachers got a pep talk via video chat from an Apple executive whom the school superintendent had come to know during his company visits.
“Both my visits there have been extraordinary,” said Curt Tryggestad, superintendent of the Little Falls Community Schools, who visited Cupertino in 2010 and earlier this year. “I was truly amazed to sit in a room with Apple vice presidents, people who were second in command to Steve Jobs.”
The demand for technology in classrooms has given rise to a slick and fast-growing sales force. Makers of computers and other gear vigorously court educators as they vie for billions of dollars in school financing. Sometimes inviting criticism of their zealous marketing, they pitch via e-mail, make cold calls, arrange luncheons and hold community meetings.
But Apple in particular woos the education market with a state-of-the art sales operation that educators say is unique, and that, public-interest watchdogs say, raises some concerns. Along with more traditional methods, Apple invites educators from around the country to “executive briefings,” which participants describe as equal parts conversation, seminar and backstage pass.
Such events might seem unremarkable in the business world, where closing a deal can involve thinly veiled junkets, golf outings and lavish dinners. But the courtship of public school officials entrusted with tax dollars is a more sensitive matter. Some critics say the trips could cast doubt on the impartiality of the officials’ buying decisions, which shape the way millions of students learn.


Mike Dean, a spokesman for Common Cause of Minnesota, a nonpartisan group that promotes open government, was critical of the Apple visits, calling them “influence peddling.” He said he believed that a Minnesota lawprohibiting government officials from accepting “anything of value” from contractors would apply to the hotel stay and dinners. And he said Apple was offering an experience that made potential buyers feel like insiders.
“There is a geek culture that very much worships Apple, and they’re feeding into that to get more contracts.”
Apple declined to discuss the executive briefings. Natalie Kerris, a spokeswoman for the company, said education was “in its DNA.” As to the public employees who participate in the trips, Ms. Kerris said: “We advise them to follow their local regulations.”
Broadly, efforts by technology vendors to get close to educators are becoming more sophisticated, said John Richards, an adjunct lecturer at the Graduate School of Education at Harvard, where he teaches about education and technology.
“What the textbook sellers had perfected for years has moved into the high-tech world,” said Mr. Richards, who also works as a consultant for technology companies in the education market.
The sales pitches come as questions persist about how effective high-tech products can beat improving student achievement. The companies say their products engage students and prepare them for a digital future, while some academics say technology is not fulfilling its promise.
Even Mr. Jobs, Apple’s co-founder, turned skeptical about technology’s ability to improve education. In a new biography of Mr. Jobs, the book’s author, Walter Isaacson, describes a conversation earlier this year between the ailing Mr. Jobs and Bill Gates, the Microsoft co-founder, in which the two men “agreed that computers had, so far, made surprisingly little impact on schools — far less than on other realms of society such as media and medicine and law.”
The comments echo similar ones Mr. Jobs made in 1996, between his two stints at Apple. In an interview with Wired magazine, Mr. Jobs said that “what’s wrong with education cannot be fixed with technology,” even though he had himself “spearheaded giving away more computer equipment to schools than anybody else on the planet.” Mr. Jobs blamed teachers’ unions for the decline in education.
Still, Mr. Jobs seemed to hold out hope that devices like the iPad could change things by replacing printed textbooks. Mr. Isaacson writes that the textbook market was the next big business Mr. Jobs hoped to disrupt with technology.
The executive briefings on Apple’s campus have been going on for more than a decade, but have received little attention, partly because participants sign nondisclosure agreements that are meant to protect the company’s technical and business secrets.
Matt Mello, director of technology for the Holly Area Schools in Oakland County, Mich., went on a two-day trip to Apple headquarters in Cupertino, Calif., in April 2010, and his description of it is similar to those of other participants.
Mr. Mello chronicled his visit using the Moleskine notebook Apple gave him. On the first day, he said, there was a light breakfast at the hotel, a ride to Apple’s campus and a briefing around a U-shaped conference table that began with company executives asking the educators about their needs. The latest Apple laptops and other products were scattered around the room. They had lunch in the gourmet cafeteria, where Mr. Mello sampled a bit of everything, and visited the company store.
“I joked that I felt like we were on hallowed ground,” Mr. Mello said of the campus. “There’s this mystique.”
Still, Mr. Mello said he was not sure what would come of a trip that had developed a few months earlier, when the regional sales representative for Apple “snuck a MacBook under my nose and got me to try it.” Soon, he said, the district was conducting a test with 30 Apple laptops and considering whether to upgrade hundreds of Windows-based computers or switch to Apple.
Mr. Mello said the sales representative told him: “If you guys are serious, we could get you an invitation to an executive briefing in Cupertino.”
The representative traveled to Cupertino for the meeting but hung in the background. The sales team wore ties, and the engineers and executives dressed casually. Sales pitches took a back seat to conversations and presentations about how students use computers. One video showed a 10-year-old boy talking about creating podcasts with a MacBook.
The group met with a local participant in Apple’s “distinguished educator” program, Ted Lai, who talked about podcasting in schools. Then, in a room called the Jim Henson Studio, they learned to create podcasts using iMovie software. Soon, Mr. Mello was convinced.
“We went there with our eyes open but hesitant. What could be so compelling as to get us to move off our base? And they did it,” Mr. Mello said. What swayed him, he said, were the presentations but also the company’s bright new monitors: “We were looking at each other thinking, ‘Wow. I can’t believe these are available at this price point.’ ”
Since then the district has switched to Apple, giving 350 laptops to teachers in 2010 and, this fall, 450 iPads and computers to high school students. The price: $637,000.
Mr. Mello was joined on the trip by two principals, two assistant superintendents and a teacher. Apple paid for meals and a stay at the Inn at Saratoga, near the Apple campus, where rates run $189 for a single room that looks onto a tranquil creek. Airfare was not included. And the group did not let Apple pick up the drink tab at the hotel, Mr. Mello said, noting: “As a school district, we’re conscious of that sort of thing.”
Rich Robinson, executive director of the Michigan Campaign Finance Network, a nonprofit watchdog group, said he did not believe the educators were violating state law. But he said the ethical issue seemed to be a gray area for public officials. “It’s acceptable business ethics,” he said. “It’s not good public ethics.”
For his part, Mr. Mello said he did not think the Apple perks had influenced him. But he said he believed that Apple, by inviting his district, which is relatively wealthy, was seeking to influence other Michigan schools. In fact, he said he was told as much by a senior sales executive during dinner at a Silicon Valley Latin American restaurant.
The executive even offered to throw in about $20,000 of wireless equipment, but the district declined because it already had other plans, Mr. Mello said.
Mr. Robinson and other watchdogs said state ethics rules were not uniform and varied widely. For instance, school officials in Nebraska, several of whom have visited Apple this year, are prohibited from accepting meals and hotels only if they agree to buy products in exchange, an overt quid pro quo that no one is suggesting is taking place.
In all, about 30 states have laws restricting gifts to state officials, laws that might invite scrutiny of Apple’s generosity, said Karen Hobert Flynn, vice president of state operations for Common Cause.
In Microsoft’s case, the company covers airfare, hotels and meals for participants in its events for teachers. It also invites administrators and school technology staff to regional meetings that aim to help them solve technical issues. Because those meetings include people who can be involved in purchasing computers and other gear, Microsoft does not pay for travel or hotels.
And in the case of both the teacher meetings and the technical briefings, Microsoft requires that attendees bring a letter certifying that if they accept meals or any other perks, they will not be violating local, state or federal ethics laws, according to Kevin Hartley, associate general counsel at the company.
There is sensitivity about these issues on the educators’ side as well. In September, a group of state officials and educators in Idaho canceled a trip to Microsoft because they worried it might appear as if the trip had unfairly influenced any eventual purchase of Microsoft products.
Mr. Tryggestad from Little Falls said that Apple did not push him to take anything that would violate state law, and that he did not think he or anyone in the district had done so.
When he went on his first visit to Apple in 2010, Mr. Tryggestad was joined by about a dozen other Minnesota superintendents. On his second visit this February, the group spent an afternoon at Stanford University talking to students and faculty who were experimenting with educational uses of technology.
In March, the district technology director visited Apple in a group that included his counterparts from schools in North Dakota, South Dakota, Nebraska and Kansas. Less than a month later, the Little Falls school board approved the big iPad purchase.
At the time the district was curious to see how students’ test scores would be affected by the use of the new devices, but the test results from one school’s pilot project last year would not be available for months. And the district decided not to wait, Mr. Tryggestad said, given the enthusiasm for the device among students and teachers.
Mr. Tryggestad said he believed Apple invited him to its campus (and also to larger education meetings in Dallas and Chicago) because he had some influence. He sits on the board of the Minnesota Rural Education Association, a lobbying group, and is on a state advisory committee for online learning.
“Maybe they looked at me as being a conduit,” he said.

The Virtual Nurse Will See You Now

By Emily Singer
Tuesday, November 1, 2011

In the hectic world of a hospital, a computer-simulated nurse can be surprisingly comforting.

VIDEO












Researchers at Northeastern University have developed a virtual nurse and exercise coach that are surprisingly likable and effective—even if they're not quite as affable as the medical hologram on Star Trek. In fact, patients who interacted with a virtual nurse named Elizabeth said they preferred the computer simulation to an actual doctor or nurse because they didn't feel rushed or talked down to.

A recent clinical trial of the technology found that Elizabeth also appears to have a beneficial effect on care. A month after discharge, people who interacted with the virtual nurse were more likely to know their diagnosis and to make a follow-up appointment with their primary-care doctor. The results of the study are currently under review for publication.

"We try to present something that is not just an information exchange but is a social exchange," says Timothy Bickmore, associate professor in Northeastern's College of Computer and Information Science. Bickmore led the research. "It expresses empathy if the patient is having problems, and patients seem to resonate with that."

Bickmore first became interested in working on "virtual agents" after seeing demonstrations of very early interactive animated characters. "I was amazed at how people were instantly mesmerized by them, and how quickly this effect vanished when the characters did something stupid," he says. "I was interested in seeing how they could be engineered to maintain the enchantment over long periods of time and be used for practical purposes beyond entertainment."

He adds that patients with little or no computer experience seem to prefer the virtual person to more standard computer interactions, because it feels more natural.

"Most people get frightened when they hear they are going to get care from a computer, so to hear so clearly that we are not short-changing patients is gratifying," says Joseph Kvedar, a physician and founder and director of the Center for Connected Health at Partners Healthcare. Kvedar has collaborated with Bickmore in the past.

To develop the computer-controlled avatars, researchers first recorded interactions between patients and nurses. They then tried to emulate the nurses' nonverbal communication by endowing the virtual character with hand gestures and facial expressions. (The resulting animation is, however, much simpler than today's sophisticated video games.)

Researchers also add small talk, asking users about local sports teams and the weather, which real nurses and coaches often do to put patients at ease. The verbal interactions are fairly basic; the nurse or trainer has a set repertoire of questions, and users choose from a selection of possible answers. For anything beyond that repertoire, the virtual agent will refer the patient to a human health-care provider.

Adding these apparently simple touches of humanity does appear to influence how people interact with the program. Patients more accurately reported their health information when interacting with the virtual character than they were when filling out a standard electronic questionnaire.

"This was designed from the ground up to be patient-friendly, warm and engaging; it's not necessarily the most lifelike and real-human-looking representation, but through trial and error, they have found the characteristics that resonate with patients," says Steven Simon, chief of general internal medicine at the VA Boston Healthcare System. "I think they are just scratching the surface in terms of how it can best be used, such as in patients with chronic conditions, such as asthma and diabetes."

Such technologies will become increasingly important with rising health-care costs and an aging population. "We already know we don't have enough health-care providers to go around, and it's only getting worse," says Kvedar. "About 60 percent of the cost of delivering health care comes from human resources, so even if you can train more people, it's not an ideal way to improve costs."

Kvedar worked with Bickmore on a second, home-based trial, in which a virtual coach called Karen encouraged overweight sedentary adults to exercise. Users checked in with Karen three times a week, and she gave them recommendations and listened to their problems. Over 12 weeks, those who talked to the coach were significantly more active than those who simply had an accelerometer to record how much they walked.

"Older adults seem to be really accepting. They like the social aspect of it," says Bickmore. "With the home-based agent, I think they would like to chat with them longer than we let them."

Some users wanted to know more about their virtual coaches, so Bickmore's team experimented with giving the characters a backstory. They found that participants whose virtual coach told them stories in the first person were more likely to log into the system than those who heard the same stories in the third person.

"They had more frequent conversations with the coach when it was being more human, and they did not report feeling more deceived," says Bickmore. He adds that when asked, participants do understand the character is virtual, but they say they sometimes forget. "They say they will feel guilty about not logging in, which means they have formed some kind of emotional bond."

But not everyone responded well to Karen. One of the challenges in broadening the use of this technology will be creating virtual characters that can learn from users and adapt to their preferences.

Bickmore's team is now working on a virtual nurse that would reside in the hospital room. Patients can talk to it about their hospital experience, report pain levels, and ask questions. The researchers are also integrating sensors into the system, to record when the patient is sleeping, for example, or to track when different doctors enter the room.

In a pilot study, patients had an average of 17 conversations with the nurse per day. "When we interviewed them afterward, we found that the agent seemed to be effective at addressing the loneliness you often feel if you're at the hospital by yourself," says Bickmore.
