This article describes the software architecture of an autonomous, interactive tour-guide robot. It presents a modular and distributed software architecture, which integrates localization, mapping, collision avoidance, planning, and various modules concerned with user interaction and Web-based telepresence. At its heart, the software approach relies on probabilistic computation, on-line learning, and any-time algorithms. It enables robots to operate safely, reliably, and at high speeds in highly dynamic environments, and does not require any modifications of the environment to aid the robot's
The EU-funded MultiMatch project aims to overcome language barriers, and media and distribution problems currently affecting access to on-line cultural heritage material. Partners are developing a vertical search engine able to harvest heterogeneous information from distributed sources and present it in a synthesized manner. To design such a system, user requirements were initially gathered and then translated into specific design features to ensure that the search engine developed was consistent with user needs. This paper presents these user requirements, the initial design of the MultiMatch

As we turn more and more to high-end computing to understand the Universe at cosmological scales, dynamic visualizations of simulations will take on a vital role as perceptual and cognitive tools. In collaboration with the Adler Planetarium and University of California High-Performance AstroComputing Center (UC-HiPACC), I am interested in better understanding the use of visualizations to mediate astronomy learning across formal and informal settings. In this research, I use quantitative methods to investigate how 122 post-secondary learners are relying on color to interpret dark matter in a
In the provision of networked services for museums, the term 'openness' crops up in a variety of contexts including open standards and open source software. In addition, the Web 2.0 environment has led to increased interest in open content and in the use of freely available networked applications which may be regarded as open services. This focus on openness for the developer or service provider can be complemented with a culture of openness which encourages the users to actively engage with services and generate their own content. It can be difficult to argue against the benefits which
While we should celebrate our success at evolving many vital aspects of the human-technology interactive experience, we question the scope of this progress. Step back with us for a moment. What really matters? Everyday life spans a wide range of emotions and experiences -- from improving productivity and efficiency to promoting wonderment and daydreaming. But our research and designs do not reflect this important life balance. The research we undertake and the applications we build employ technology primarily for improving tasks and solving problems. Our claim is that our successful future

In October 2005, the National Science Foundation brought members of its nanoscale science and engineering education (NSEE) projects to Arlington, VA for a 2-day workshop to explore the status of on-going efforts and to forge collaborations at the national level that would facilitate future efforts. NSF currently funds NSEE projects through the Division of Elementary, Secondary, and Informal Education (ESIE), the Directorate for Engineering as part of the Nanoscale Science and Engineering Centers (NSEC), National Nanotechnology Infrastructure Network (NNIN), the Network for Computational
NSF's Cyberinfrastructure Vision for 21st Century Discovery is presented in a set of interrelated chapters that describe the various challenges and opportunities in the complementary areas that make up cyberinfrastructure: computing systems, data, information resources, networking, digitally enabled-sensors, instruments, virtual organizations, and observatories, along with an interoperable suite of software services and tools. This technology is complemented by the interdisciplinary teams of professionals that are responsible for its development, deployment and its use in transformative
Discovering and understanding the temporal evolution of events hidden in text corpora is a complex yet critical task for knowledge discovery. Although mining event dynamics has been an important research topic leading to many successful algorithms, researchers, research and development managers, intelligence analysts and the general public are still in dire need of effective tools to explore the evolutionary trends and patterns. This exploratory project focuses on developing and validating a novel idea called narrative animation. Narrative animation uses animated visualizations to narrate, explore, and share event dynamics conveyed in temporally evolving text collections. Film art techniques are employed to leverage the animated visualizations in information organization and change detection, with the goals of enhancing analytical power and user engagement. A prototype system called CityStories is being developed to generate narrative animations of events in cities derived from web-based text. If this novel, risky research is successful, it is expected to yield fundamental results in narrative animation that can advance the current paradigm in information visualization and visual analytics by developing novel techniques in using animations for presenting and analyzing dynamic abstract data at a large scale. The pilot system CityStories system is expected provide a novel network platform for education, entertainment, and data analytics. It will engage general users such as students, teachers, journalists, bloggers, and many others in web information visualization and study. Results of this research will be disseminated through publications, the World Wide Web, and collaborations with researchers and analysts. The project web site (http://coitweb.uncc.edu/~jyang13/narrativeanimation/narrativeanimation.htm) will include research outcomes, publications, developed software, videos, and datasets for wide dissemination to public.
How can research on teaching and learning be used to improve the design of e-content? The contents of this report are based on a series of seminars conducted during 2003 and 2004, funded by the Economic & Social Research Council (ESRC), that were coordinated by Lydia Plowman, University of Stirling. They were also sponsored by a number of organisations including Futurelab. Each seminar was attended by researchers from universities, creators and managers of companies that make educational resources, and people engaged in policy making or representing Government agencies
To explore how the United States can harness the powerful features of digital games for learning, the Federation of American Scientists, the Entertainment Software Association, and the National Science Foundation convened a National Summit on Educational Games, on October 25, 2005 in Washington, DC. The Summit brought together nearly 100 experts to discuss ways to accelerate the development, commercialization, and deployment of new generation games for learning.

The NASA Science Research Mentoring Program (NASA SRMP) is an established mentoring program that presents the wonders of space exploration and planetary sciences to underserved high school students from New York City through cutting-edge, research-based courses and authentic research opportunities, using the rich resources of the American Museum of Natural History. NASA SRMP consists of a year of Earth and Planetary Science (EPS) and Astrophysics electives offered through the Museum’s After School Program, year-long mentorship placements with Museum research scientists, and summer programming through our education partners at City College of New York and the NASA Goddard Institute for Space Studies. The primary goals of the project are: 1) to motivate and prepare high school students, especially those underrepresented in science, technology, engineering and math (STEM) fields, to pursue STEM careers related to EPS and astrophysics; 2) to develop a model and strategies that can enrich the informal education field; and 3) to engage research scientists in education and outreach programs. The program features five in-depth elective courses, offered twice per year (for a total of 250 student slots per year). Students pursue these preparatory courses during the 10th or 11th grade, and a select number of those who successfully complete three of the courses are chosen the next year to conduct research with a Museum scientist. In addition to providing courses and mentoring placements, the program has produced curricula for the elective courses, an interactive student and instructor website for each course, and teacher and mentor training outlines.
Mission to Mars engages 6th-8th grade students in the science, engineering and careers related to Mars exploration. The program is led by the Museum of Science and Industry, Chicago, and includes as partners Challenger Learning Centers in Woodstock, IL, Normal IL and three NASA Centers (Jet Propulsion Laboratory, Marshall Space Flight Center, and Johnson Space Center). The project aims to:
Link, via videoconference, urban and rural middle school students from low income communities in an exploration of space science
Develop and launch programs that showcase NASA Center research
Enrich middle school curricula and promote learning about NASA’s space missions with experiences that inspire youth to pursue in NASA-related STEM careers.
Programs and products produced include:
3 videoconference program scenarios that highlight research being conducted at NASA Centers
Pre- and post-event curriculum materials designed for middle school classrooms
Teacher professional development workshops
Communication support for NASA professionals
iPad apps utilized during the program
Since the program launched five years ago, Mission to Mars has served 7,676 students. MSI seeks to provide opportunities for all learners, and works to remove barriers to participation in high-quality science learning experiences. Mission to Mars allows MSI to engage more Chicago Public Schools (where 86% of students are economically disadvantaged) in real and relevant science experiences that may lead to STEM careers.
As MSI’s CP4SMP grant comes to an end, the Museum has committed to continued delivery of the program through 2 Mission to Mars Learning Labs, offered to 6-8th grade school groups visiting on field trips. Live videoconferencing with JPL and Johnson will occur during roughly half of the sessions. Our Challenger Learning Center partners will integrate Mission to Mars activities, materials and iPad apps into their own Mars-themed programs. Together these efforts extend the transformative hands-on science experiences developed under the Mission to Mars grant to a whole new audience of middle school students and teachers.
