Study: Human traits make robots likable

Imitation is not just the best form of flattery--it's also good interface design. A study shows that talking computers that copy a user's unique vocal inflections seem easier to use.

The researchers think that a key component of machine likability is the ability to mirror the "music"--the rhythm and pitch--of a user's speech.

This finding stemmed from an experiment conducted by Japanese researcher Noriko Suzuki's team at ATR Media Information Science Laboratories in Kyoto, reported scientific journal New Scientist.

According to the report, the researchers looked at how social bonds develop between people. When we sense that a person is making an effort to copy the way that we speak, we tend to like that person more, they believed.

The group asked volunteers to work with an animated computer character that had the linguistic capabilities of a 1-year-old child, the report said.

The participants were told to make toy animals out of blocks on the computer screen and to say the names of these animals to the character.

The report said the character would in return hum sounds that mimicked the volunteers' speech in rhythm, intonation, loudness and pitch.

The users were then asked to rate the character on attributes such as cooperation, learning ability, task achievement, comfort, friendliness and sympathy.

Results showed that the animated character scored highest on all counts when it mimicked 80 percent of a volunteer's voice--proving that the advice "It's not just what you say, but how you say it" also counts for machines, according to the report.

"The user felt some kind of friendly emotion from the computer, even though it was just copying the stresses and intonation of their own voices," Suzuki said. The research team said the character did not imitate the volunteers' voices fully, but created the impression that it had free will and thus was more human and more loveable.

Suzuki said in the report that this revelation can help forge closer bonds between people and machines. "Sometimes people are afraid of robots," he said. "But if robot voice patterns are improved, people may warm up to them."

That opinion is shared by Timothy Bickmore, an expert on human-computer interaction at the Massachusetts Institute of Technology.

Bickmore said in the report that such mimicry can indeed help build rapport between humans and computerized characters or robots. He added that this finding could be applied in areas such as entertainment, computer gaming and toys.

The history of personal computing is filled with attempts to make daunting interfaces more likable through the use of human-like avatars or characters such as Microsoft's Office helpmate Clippy or its Bob software.

Pentagon seeks to sort and store lifetime experience

29.05.2003
3.30pm - By JIM WOLF

WASHINGTON - The Pentagon is shopping for ways to capture everything a person sees, says and hears as part of a project it says is meant to help create smarter robots.

The projected system called Lifelog would suck in all of a subject's experience -- from phone numbers dialed and emails viewed to every breath taken, step made and place gone.

The idea is to index the material, and make patterns easily retrievable in an effort to make machines think more like people, learning from experience.

The Defence Advanced Research Projects Agency, or DARPA, the Pentagon's cradle for revolutionary technologies, is sponsoring a competition to bring out proposals for setting up such a system.

The resulting knowhow could give US war fighters more effective computers capable of building on a user's past and interpreting his or her commands, said Jan Walker, a DARPA spokeswoman.

She said the new project had nothing to do with DARPA's Terrorism Awareness Information programme, a research initiative into creating a giant surveillance system aimed at thwarting terrorism which has been criticised by civil rights groups.

The LifeLog goal is to create a searchable database of human lives -- initially those of the developers -- to promote artificial intelligence, the agency said.

The technology will advance a new class of systems able to reason in a number of ways, learn from experience and "respond in a robust manner to surprises," DARPA's Information Processing Technology Office said.

To do so, it must index the mumbo jumbo of daily life and make it possible "to infer the user's routines, habits and relationships with other people, organisations, places and objects, and to exploit these patterns to ease its task," the announcement said.

Perhaps eager to avoid any comparisons with George Orwell's all-seeing "Big Brother" in the classic novel 1984, DARPA said respondents must address "human subject approval, data privacy and security, copyright and legal considerations that would affect the LifeLog development process."

Steven Aftergood, who tracks government secrecy for the Federation of American Scientists, said he was not prepared to reject the LifeLog initiative or call it illegitimate.

"But, you know, it's one more programme that demands vigilant oversight," he said in a telephone interview. "The more personal experience that can be captured by digital means, the more vulnerable that experience is to unwanted surveillance."

Biometric comes to Topeka

By Amy Bauer
The Capital-Journal
May 20, 2003

The president of Falley's/Food 4 Less of Topeka envisions a day when consumers will shop for groceries, approach a cash register and, rather than reach for a wallet or purse, pay for the entire purchase with the touch of a finger.

Topeka's Falley's and Food 4 Less stores are nearing this future with the installation of a fingerprint recognition system for check cashing. The stores have installed Biometric Access Corp.'s SecureTouch Touch-•-Pay systems at customer service counters in all eight Topeka stores for use by those wanting to cash payroll or government checks, or personal checks up to $25.

"You come in and you can put your finger on this piece of glass. It knows it's you," said Stan Edde, Falley's/Food 4 Less of Topeka president. "What it's all designed to do is to keep your ID out of sight."

By taking a digital image of a customer's right and left index fingers, the system creates files from which it can match the unique pattern and ridge characteristics of a person's fingerprint. In order to complete future check-cashing transactions, the person standing at the counter must be the same as the person who enrolled.

The new system currently isn't used for purchases in the regular check-out line. It only is used for check cashing at the service desk.

Food 4 Less, S.W. 21st and Fairlawn, has installed a new fingerprint system called Biometric for check-cashing purposes. The technology allows people to cash checks with the touch of a finger and helps prevent fraudulent checks."It gave us the ability to serve customers better," said Mike Moore, director of store operations for Falley's/Food 4 Less. "We couldn't accept payroll checks for more than $400 because of the liability."

The stores now cash payroll checks up to $800, with a processing fee of $1 per $100.

Moore said customers also are more secure in the knowledge that a lost check can't be cashed by anyone else.

A trial period that began in September in its Wichita stores sold Falley's/Food 4 Less on the system, Moore said, and Touch-•-Pay was expanded to Topeka and St. Joseph, Mo., stores in February. Moore said the rest of Falley's/Food 4 Less' 31 stores will have the system installed by the end of June.

While not wanting to quote exact figures, Moore said the stores are cashing more checks since the switch.

"We're only doing the Biometrics at this point for check-cashing purposes," Moore said. "We're looking at the option of rolling it out to the check stands also."

Customers sign an agreement with the company that gives it permission to keep information including a person's driver's license and Social Security numbers in the Touch-•-Pay system. Ken Knese, vice president of point of sale for the Austin, Texas-based Biometric Access Corp., said no one at the stores has access to the stored customer data and said Touch-•-Pay uses an encryption system similar to that for credit card transactions.

An employer name and contact are required, and Biometric Access Corp. verifies a person is employed at the company listed before approving payroll check cashing. A copy of the type of check to be cashed also is scanned into the system, with routing numbers matched and authenticity verified. Hence, there is a waiting period of three to seven days between sign-up and the time an individual's first check can be cashed.

"With that information, it makes it very difficult for a fraudulent check to be cashed," Knese said.

Individuals who have personal checks rejected for insufficient funds, for instance, can be flagged in the system so the problem can be addressed or future check cashing denied.

Knese said Biometric Access Corp. is working with other grocers nationally that have installed the Touch-•-Pay system throughout entire stores, wherever money changes hands.

He said that at stores using the full system, enrollment is optional, though he said he has seen enrollment continue to increase as more skeptical consumers watch others using the system. Knese said the average check transaction goes from 1.5 minutes on paper to less than three seconds with the Touch-•-Pay system.

For checkout transactions, customers can register credit cards, food stamp or other benefit cards, or a bank account so that future transactions can take place without the cards present or with a paperless check, or customers can choose to pay the old-fashioned way, with cash.

"It's not a Big Brother situation," Knese said. "It's information that's there for the sole purpose of making it simpler and easier to do a transaction at the supermarket."

Meanwhile, the system protects grocers from fraudulent checks.

"If I'm a crook, do I want to leave the best piece of evidence behind?" he asked, holding up his index finger. "If I'm going to do it, I'm going to go where there's the least resistance.

"It's more meant to make it easier for the good customer to do business with you. It rewards the good people and it frustrates the bad people."

Touch of a finger

Local Food 4 Less and Falley's stores are using Biometric Access Corp.'s SecureTouch Touch-n-Pay system for check cashing. Here is how a transaction works:

A customer approaches the customer service counter and either swipes a driver's license, credit card or other ID card with a magnetic strip, or types in a home phone number. The system prompts the person to place a finger on the small oval scanner, and a digital smiley face gives a wide grin when the right image has been captured. The system confirms or denies the match and allows the user to choose the type of transaction.

Biometric technology identifies an individual through unique characteristics, such as fingerprints. The technology also is being used for:

• Building access in health care or other settings

• Time clocks for employees

• Child care centers, to identify relatives

• Child ID programs

Ya know. I do intend to eventually put something here. But today I feel like crap, and all this week I was too busy at work to take enough time off to run home and get my digital cable box and take it back to the cable co. Why? Because back to high speed internetland I go, and though, in my opinion, half of the best channels are the digital ones, I can't spend $60 a month for something I'm not using.

The new computer's gonna love this once I get it connected... if I can get the damn thing connected before I turn completely gray.

What's the deal with life these days? So much shit to do, and no time to do it, yet we're all busy making sure we have 15 ways to contact each other in case we missed something else we didn't have time to do.

I feel just gross. Cartman says: Screw you guys, I'm going home.
