University of North Carolina at Chapel Hill Biography:
Title: Immersive Integration for Virtual and Human-Centered Environments We envision future work and play environments that are more effectively human-centered with the user’s computing interface being more closely integrated with the physical surroundings than today’s conventional computer display screens and keyboards. We are working toward realizable versions of such environments, in which multiple video projectors and digital cameras enable every visible surface to be both measured in 3D and used for display. If the 3D surface positions are transmitted to a distant location, they may also enable distant collaborations to become more like working in adjacent offices connected by large windows. In one prototype, depth maps are calculated from streams of video images and the resulting 3D surface points are displayed to the user in head-tracked stereo. Another prototype allows direct “painting” onto movable objects -- a dollhouse, for example. One long-term goal is advanced training for trauma surgeons by immersive replay of recorded procedures. More generally, we hope to demonstrate that the principal interface of a future computing environment need not be limited to a screen the size of one or two sheets of paper. Just as a useful physical environment is all around us, so too can the increasingly ubiquitous computing environment be all around us -- becoming more effectively human-centered and integrated into our physical surroundings. |

University of Washington Biography:
Title: Transparent Interfaces to Complex Software: Helping Users Understand Their Tools In the past, ease
of use has been the primary motivation for visual and human-centric
techniques. Now there is another reason for them. As software systems become
increasingly sophisticated and as they treat more and more sensitive
information, users have growing difficulty to understand them and to trust
the ways their private information is manipulated. Thus designers must give
more importance to the understandability of software. Transparency is an
aspect of
software comprising openness in design, glass-box features, and support for
interactive inspection. This talk describes these components of
transparency and illustrates them in the context of three application
domains: visual programming systems, digital image processing, and
computer-based learning environments. |

ARTiSAN Software Tools Biography:
Title: SysML with ARTiSAN Studio* Since its adoption in 1997, the Unified Modeling Language (UML) has proved very popular with software engineers and has become the de facto standard as a visual modeling language for software engineers. However, this software focus of UML has discouraged many systems engineers from adopting it in earnest. Those who did adopt UML developed strategies to cope with its shortcomings. A common approach was to model additional systems engineering concepts in other modeling tools. This made it difficult to integrate the different viewpoints and achieve traceability. Fortunately, with the release of UML 2.0 and the ensuing extensions to it in SysML - the soon-to-be adopted Systems Modeling Language - the systems engineering community has a real alternative to systems modeling that provides a more integrated approach to systems and software engineering. Since its inception in 1997, ARTiSAN has endeavored to bridge the gap between systems and software engineering modeling by adding systems engineering extensions to the UML and, as a key member of the SysML initiative, is well poised to support these emerging standards for systems and software modeling. This presentation will provide a brief overview of the major extensions proposed by SysML, and will summarize how ARTiSAN's latest release of its flagship product Studio (version 6.0) takes the lead in supporting these concepts. *This keynote speech is for both the Visual Modeling for Software Intensive Systems workshop and the main conference. |

Henry Fuchs is the Federico Gil Professor of Computer Science, Adjunct
Professor of Biomedical Engineering, and Adjunct Professor of Radiation
Oncology at UNC Chapel Hill. He has been active in computer graphics since
the 1970’s, with rendering algorithms (BSP Trees), hardware (Pixel-Planes
and PixelFlow), virtual environments, tele-immersion systems and medical
applications. He is a member of the National Academy of Engineering, a
fellow of the American Academy of Arts and Sciences, recipient of the ACM-Siggraph
Achievement Award, and the Academic Award of the National Computer Graphics
Association.
Steven
Tanimoto received his bachelors degree in 1971 from Harvard University where
he studied computer graphics and visual languages under Danny Cohen, Eric
Martin, Rudolf Arnheim, Alfred Guzzetti, and John M. Kennedy. He received
his Ph.D. from Princeton University in 1975 with a dissertation on
hierarchical methods in image processing supervised by Theodosios Pavlidis.
He taught at the University of Connecticut from 1975 to 1977 and has been a
member of the faculty of the University of Washington in Seattle since 1977.
He served as Editor-in-Chief of the IEEE Transactions on Pattern Analysis
and Machine Intelligence from 1986-90 and is the author of The Elements of
Artificial Intelligence Using Common Lisp, 2n ed, published by W.H.Freeman
in 1995. His current research focuses on applying techniques from
artificial intelligence and pattern recognition to online learning
environments.
Manohar Rao is an
Application Engineer at ARTiSAN Software Tools. He has extensive experience
assisting large systems and software engineering organizations with the
adoption and application of UML into their systems development processes and
projects. His role at Artisan includes sales presentations, consulting and
training in UML. His own adoption of UML goes back to his days as a C and
C++ developer and even extends to his role as product manager for various
software products.
