Papers delivered at three conferences in the US and Europe philosoft@live.comUSC studies document that kids with ASD actively interact with robots; creation of therapy tools is next step Feil-Seifer, Matarić and assistants: "a doorway into the attention " of ASD children. Papers delivered at three conferences in the US and Europe this summer report on new research at the University of Southern California Viterbi School of Engineering studying interactions of children with Autism Spectrum Disorders (ASD) with bubble-blowing robots. The preliminary studies, by Professor Maja Matarić and PhD student David Feil-Seifer of the USC Interaction Laboratory, confirm what has been widely reported anecdotally: that ASD children in many cases interact more easily with mechanical devices than with humans. Matarić and Feil-Seifer, both specialists in Socially Assisted Robotics (SAR), are now engaged in further research to confirm their findings, and to develop a robot "control architecture" which will tailor robot interactions to the specific needs of ASD children to help therapists treating their condition. The initial study, reported in the June Conference on Interaction Design for Children with Special Needs in Chicago, tested whether interaction as opposed to simple passive observation was going on between ASD children and a colorful bubble-blowing wheeled robot. Bubblebot: When set in "contingent " behavior mode, children's actions can control its behavior. A video can be viewed at http://www.youtube.com/watch?v=VRNWRlSmiA0 The robot had two settings. In one, it carried on its rolling and bubble blowing on its own internal schedule, regardless of the behavior of the child. In the other, "when the child pushes a button, then the bubbles blow," in the words of the Chicago presentation. The study watched the children and observed differences. "We found that the behavior of the robot affects the social behavior of a child (both human-human interaction and human-robot interaction): social behavior with a contingent robot was greater than with a random robot. "Total speech went from 39.4 to 48.4 utterances, robot speech from 6.2 to 6.6 utterances, and parent speech from 17.8 to 33 utterances. Total robot interactions went from 43.42 to 55.31, with button pushes increasing from 14.69 to 21.87 and other robot interactions going from 24.11 to 28. Total directed interactions (interactions that were clearly directed at either the robot or the parent) went up from 62.75 to 89.47. Generally, when the robot was acting contingently, the child was more sociable." While only four children were part of the initial study, Feil-Seifer and Matarić believe the work clearly demonstrates the ability of robots to actively engage with ASD children - "offer a doorway into their attention," Matarić says. A much more extensive follow-up with more subjects is already in progress, in collaboration with Los Angeles Childrens Hospital and the Autism Genetic Resource Exchange. Two other presentations by Feil-Seifer and Matarić, at the 11th International Symposium on Experimental Robotics 2008 in Athens, Greece in July, 2008, and at the IEEE Proceedings of the International Workshop on Robot and Human Interactive Communication, discuss these results in more detail, particularly in regard to the "Behavior-Based Behavior Intervention Architecture" (B3IA) they have developed to make the robots flexible and useful tools help ASD children. This architecture (the system, including robotic and non-robotic components, plus provisions for recording and analyzing the proceedings) is based on an ASD therapy format called DIR/Floortime, in which a therapist shares floor with various toys used to try to engage the child. Matarić and Feil-Seifer, in collaboration with Dr. Marian Williams from Childrens Hospital Los Angeles and Shri Narayanan from Viterbi School's Department of Electrical Engineering, are replacing toys with robots, both the rolling robots with horns and bubble blowers used in the initial results, and humanoid robots capable of smiles and otherresearch,research,directory,research,news,new,researchUSC studies document that kids with ASD actively interact with robots; creation of therapy tools is next step Feil-Seifer, Matarić and...<br/> <br/> [[ This is a content summary only.

One of the results of these discoveries led astronomers to understand more about the life and evolution of caphilosoft@live.com The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion year-old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led astronomers to understand more about the life and evolution of cannibal galaxies. Globular star clusters, dense bunches of hundreds of thousands of stars, contain some of the oldest surviving stars in the Universe. A new international study of globular clusters outside our Milky Way Galaxy has found evidence that these hardy pioneers are more likely to form in dense areas, where star birth occurs at a rapid rate, instead of uniformly from galaxy to galaxy. Astronomers used the NASA/ESA Hubble Space Telescope to identify over 11 000 globular clusters in the Virgo cluster of galaxies, most of which are more than 5 billion years old. Comprised of over 2 000 galaxies, the Virgo cluster is located about 54 million light-years away and is the nearest large galaxy cluster to Earth. Along with Virgo, the sharp vision of Hubble's Advanced Camera for Surveys (ACS) resolved the star clusters in 100 galaxies of various sizes, shapes, and brightness – even in faint, dwarf galaxies. "It's hard to distinguish globular clusters from stars and galaxies using ground-based telescopes", explained Eric Peng of Peking University in Beijing, China, and lead author of the Hubble study. Hubble’s “eye” is so sharp that it was able to pick out the fuzzy globular clusters from stars in our galaxy and from faraway galaxies in the background. "With Hubble we were able to identify and study about 90 percent of the globular clusters in all our observed fields. This was crucial for dwarf galaxies that have only a handful of star clusters". The team found a bounty of globular clusters (from a few dozen to several dozen) in most of the dwarf galaxies within 3 million light-years of the cluster’s centre. This happens to be the same region where the giant elliptical galaxy Messier 87 resides. These numbers were surprisingly high considering the low masses of the dwarfs they inhabited. By contrast, dwarfs in the outskirts of the cluster had fewer globulars. “Our study shows that the efficiency of star cluster formation depends on the environment”, said Patrick Cote of the Herzberg Institute of Astrophysics in Victoria, Canada. “Dwarf galaxies closest to Virgo's crowded centre contained more globular clusters than those farther away”. Astronomers have long known that the giant elliptical galaxy at the cluster’s centre, Messier 87, also hosts a larger than predicted population of globular star clusters. However, the origin of so many globulars has been a long-standing mystery. Astronomers have theorised that many of the clusters may have been snatched from smaller galaxies that ventured too close to it. “We found few or no globular clusters in galaxies within 130 000 light-years from Messier 87, suggesting the giant galaxy stripped the smaller ones of their star clusters”, Peng said. “These smaller galaxies are contributing to the buildup of Messier 87”. Evidence of Messier 87’s galactic cannibalism comes from an analysis of the globular clusters’ composition. “In Messier 87 there are three times as many globulars deficient in heavy elements, such as iron, than globulars rich in those elements”, Peng said. “This suggests that many of these ‘metal-poor’ star clusters may have been stolen from nearby dwarf galaxies, which also contain globulars deficient in heavy elements”. Studying globular star clusters is critical to understanding the early, intense star-forming episodes that mark galaxy formation. They are known to reside in all but the faintest of galaxies. “Star formation near the core of Virgo is very intense and occurs in a small volume over a short amount of time”, Peng noted. “It may be more rapid and more efficient than star formation in the outskirts. The high star-formation rate may be driven by the gravitational collapse of dark matter, an invisible form of matter, whresearch,research,directory,research,news,new,researchThe NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion year-old globular clusters in the Virgo cluster of galaxies.
