Creating and editing large graphs and node-link diagrams are crucial activities in many application areas. For them, we consider multi-touch and pen input on interactive surfaces as very promising. This fundamental work presents a user study investigating how people edit node-link diagrams on an interactive tabletop. The study covers a set of basic operations, such as creating, moving, and deleting diagram elements. Participants were asked to perform spontaneous gestures for 14 given tasks. They could interact in three different ways: using one hand, both hands, as well as pen and hand

Zooming user interfaces are increasingly popular on mobile devices with touch screens. Swiping and pinching finger gestures anywhere on the screen manipulate the displayed portion of a page, and taps open objects within the page. This makes navigation easy but limits other manipulations of objects that would be supported naturally by the same gestures, notably cut and paste, multiple selection, and drag and drop. A popular device that suffers from this limitation is Apple’s iPhone. In this paper, we present Bezel Swipe, an interaction technique that supports multiple selection, cut, copy
Most current multi-touch capable interactive user interfaces for tabletop are built from custom toolkits that are decoupled from, and on top of, the “Desktop” provided by the underlying Operating System. However, this approach requires that each individual touch system build their own suite of touch capable custom applications (such as photo browsers), usually resulting in limited functionality. In this paper, we propose a software architecture for supporting and integrating multi-touch capability on existing desktop systems, where multi-touch and multiple single pointer input can be used

WNET is producing "The Human Spark," a multimedia project that includes a four-part television series (4 x 60 min) for national primetime broadcast on PBS, innovative outreach partnerships with museums, an extensive Web site and outreach activities, including a Spanish-language version and companion book. Hosted by Alan Alda, "The Human Spark" will explore the intriguing questions: What makes us human? Can the human spark be found in the differences between us and our closest genetic relative -- the great apes? Is there some place or process unique to the human brain where the human spark resides? And if we can identify it, could we transfer it to machines? The programs will explore these questions through presenting cutting-edge research in a number of scientific disciplines including evolution, genetics, cognitive neuroscience, behavioral science, anthropology, linguistics, AI, robotics and computing. The series will highlight opposing views within each field, and the interdisciplinary nature of science, including its intersection with the humanities. The series will develop a new innovative format, the "muse concept", which involves pairing the host with a different scientific expert throughout each program. The outreach plan is being developed with a consortium of four leading science museums, American Museum of Natural History in New York, Museum of Science in Boston, The Exploratorium in San Francisco, and the Fort Worth Museum of Science and History, paired with their respective local public television stations. An additional six museums and local broadcasters will be chosen through an RFP process to develop local initiatives around the series. Multimedia Research and Leflein Associates will conduct formative as well as summative evaluations of the series and web.

Maine is a rural state with unequal access to computers and information technology. To remedy this, the Maine laptop program supplies iBooks to every seventh and eighth grade student in the state. The goal of EcoScienceWorks is to build on this program and develop, test and disseminate a middle school curriculum featuring computer modeling, simple programming and analysis of GIS data coupled with hands-on field experiences in ecology. The project will develop software, EcoBeaker: Maine Explorer, to stimulate student exploration of information technology by introducing teachers and students to simple computer modeling, applications of simulations in teaching and in science, and GIS data manipulation. This is a three-year, comprehensive project for 25 seventh and eighth grade teachers and their students. Teachers will receive 120 contact hours per year through workshops, summer sessions and classroom visits from environmental scientists. The teachers' classes will field test the EcoScienceWorks curriculum each year. The field tested project will be distributed throughout the Maine laptop program impacting 150 science teachers and 17,000 middle school students. EcoScienceWorks will provide middle school students with an understanding of how IT skills and tools can be used to identify, investigate and model possible solutions to scientific problems. EcoScienceWorks aligns with state and national science learning standards and integrates into the existing middle school ecology curriculum. An outcome of this project will be the spread of a field tested IT curriculum and EcoBeaker: Maine Explorer throughout Maine, with adapted curriculum and software available nationally.

This planning effort, a collaboration of teams at the University of Maryland, Cornell University, Carnegie Mellon University and the Sciencenter of Ithaca, deals with the development and testing of a unique methodology for educating youth in computer programming. Through a mobile robot that is cleverly disguised as a small animal, participants will learn to manipulate the system by physically moving it as well as setting variables via electronic buttons thereby learning programming and design. The eventual use of this system and methodology is in museum exhibits so preliminary survey data will be gathered from various venues that presently use less capable devices. Iterative testing will be done at the Sciencenter in its exhibits.
The Cryptoclub: Cryptography and Mathematics Afterschool and Online is a five-year project designed to introduce middle school students across the country to cryptography and mathematics. Project partners include the Young Peoples Project (YPP), the Museum of Science and Industry in Chicago, and Eduweb, an award-winning educational software design and development firm. The intended impacts on youth are to improve knowledge and interest in cryptography, increase skills in mathematics, and improve attitudes towards mathematics. The secondary audience is leaders in afterschool programs who will gain an increased awareness of cryptography as a tool for teaching mathematics and adopt the program for use in their afterschool programs. Project deliverables include online activities, online cryptography adventure games, interactive offline games, a leader\'s manual, and training workshops for afterschool leaders. The project materials will be developed in collaboration with YPP staff and pilot tested in Year 3 at local afterschool programs and YPP sites in Chicago in addition to four national sites. Field testing and dissemination occurs in Year 4 at both local sites in Chicago and national locations such as afterschool programs, science centers, and community programs. Six 3-day training workshops will be provided (2 per year in Years 3-5) to train afterschool leaders. It is anticipated that this project will reach up to 11,000 youth, including underserved youth in urban settings, and 275 professional staff. Strategic impact resulting from this project includes increased awareness of cryptography as a STEM topic with connections to mathematics as well a greater understanding of effective strategies for integrating and supporting web-based and offline activities within informal learning settings. The Cryptoclub project has the potential to have a transformative impact on youth and their understanding of cryptography and may serve as a national model for partnerships between afterschool and mentoring programs.

WGBH is producing the fifth and sixth seasons of NOVA scienceNOW, a multimedia project that addresses a wide array of science, technology, engineering, and mathematics subjects via multiple platforms. They include national PBS broadcast, the PBS web site, and innovative outreach activities such as an expanded Science Café initiative. Hosted by astrophysicist Dr. Neil deGrasse Tyson, Season Five will air in 2010; Season Six in 2011. The focus is "stories of transformative research," e.g., nanotechnology, stem cells, quantum computing, as well as clean energy, and climate change. Project goals are to "produce a lasting impact on Americans' appreciation for and understanding of current scientific research," and to encourage an interest in STEM careers among younger viewers. Building upon solid prior work, the proposed project is finding new ways to interweave the television show, web materials, and Science Cafés to provide multiple entry points and pathways for the audience. For example, they will produce 32 web-only scientist profiles supported by a blog and social media tools, and then train these scientists as presenters for the Science Cafés. NOVA is planning a new strategy to maximize carriage and increase audience for the six new programs per year; the programs will run consecutively in the NOVA Wednesday evening primetime slot during the summer. During Season Three, over 2.7 million television viewers per week tuned in NOVA scienceNow, with 62,000 unique visitors to the web site per month and 75 active Science Cafés across the country. The expanded Science Café initiative is designed to become self-sustaining beyond the grant period through new partnerships with groups such as the Astronomical Society of the Pacific, the American Chemical Society, and the Coalition for the Public Understanding of Science. The project will also collaborate with the Association of Science-Technology Centers and science centers around the country to host Science Cafés featuring scientists profiled on the web. Goodman Research Group will assess the reach and effectiveness of Seasons Five and Six. The focal/primary evaluation activity is a viewing and engagement study on the influence of viewing the series along with accessing and participating actively with the increased web and outreach offerings. This study will comprise web-based surveys with adaptive branching patterns, which will include data collection from a variety of participants and will focus on participants? use of the series, website, and outreach. The summative evaluation will measure how the project is reaching these audience segments, while also meeting the overall goals of increasing public understanding of science and engagement in science-related activities.
This is a proposal for a 3 year, $1,297,456 project to be conducted as collaboration among 5 higher education institutions and one school system across the country, with St. Joseph's University in Philadelphia, PA serving as the lead institution (other collaborators are from Colorado School of Mines, Ithaca College, Santa Clara University, Duke University, and Virginia Beach School System). The primary goal is to attract and retain students in computer science, especially women and underrepresented minorities (including two EPSCoR states). To this end, the project will use Alice, a software program that utilizes 3-D visualization methods, as a medium to create a high-level of interest in computer graphics, animation, and storytelling among high school students, hence to build understanding of object-based programming. Such an IT focus on media and animation is aligned with national computer science standards. The project will build a network of college and high school faculty, who will offer workshops and provide continuing support during the academic year. In each site, pairs of teachers from each participating school (total = 90) will learn with university faculty via a 3-week summer program in which an introduction to using Alice for teaching will be followed by teacher development of materials for students that will then be used to teach high school students. An experimental start at one site will be followed by implementation at four additional sites and culminated with revised implementation at the sixth site (1-4-1 design).
