Inspiring Modeling


Abstract

An interesting question is whether a machine can assist humans in being creative and inspire a user during the creation of 3D models or a shape in general. One possible means to achieve this is through a design gallery which presents a variety of computed suggestive designs from which the user can pick the ones he likes the best. The ensuing challenge is how to come up with intriguing suggestions which inspire creativity, rather than banal suggestions which stall the design process. In my talk I will discuss about the notion of creative modeling, synthesis of inspiring examples, the analysis of a set, and show a number of recent works that step towards this end.

Speaker's Brief Bio

Daniel Cohen-Or is a professor at the School of Computer Science,Tel Aviv University. He received his B.Sc. cum laude in both mathematics and computer science (1985), an M.Sc. cum laude in computer science (1986) from Ben-Gurion University, and his Ph.D. degree from the Department of Computer Science (1991) at State University of New York at Stony Brook. He received the 2005 Eurographics Outstanding Technical Contributions Award. His research interests are in computer graphics, in particular, modeling and synthesis. His main interest right now is in: shape analysis and synthesis, shape modeling and surface reconstruction.

The Science of Social Interactions on the Web


Abstract

Social interactions have always been an important part of human learning and experience. We now know that social interactions are critical in many knowledge and information processes. Research has shown results ranging from influences on our behavior from social networks [Aral2012] to our understanding of social belonging on health [Walton2011], as well as how conflicts and coordination play out in Wikipedia [Kittur2007]. Interestingly, social scientists have studied social interactions for many years, but it wasn't until very recently that researchers are able to study these mechanisms through the explosion of services and data available on web-based social systems.

In this talk, I plan to illustrate a model-driven approach to researching social interactions on the Web. Our research methods and systems are informed by models such as information scent, sensemaking, information theory, probabilistic models, and evolutionary dynamic models. These models have been used to understand a wide variety of user behaviors, from individuals interacting with social bookmarks in Delicious to groups of people working on articles in Wikipedia. These models range in complexity from a simple set of assumptions to complex equations describing human and group behaviors. By using this model-driven approach, we further our understanding of how knowledge is fundamentally constructed in a social context, and a path forward for further social interaction research.

Speaker's Brief Bio

Ed H. Chi is a Staff Research Scientist at Google, focusing on social interaction research relating to social search, recommendation, annotations, and analytics. Previous to Google, he was the Area Manager and a Principal Scientist at Palo Alto Research Center's Augmented Social Cognition Group, where he led the group in understanding how Web2.0 and Social Computing systems help groups of people to remember, think and reason. Ed completed his three degrees (B.S., M.S., and Ph.D.) in 6.5 years from University of Minnesota, and has been doing research on user interface software systems since 1993. He has been featured and quoted in the press, including the Economist, Time Magazine, LA Times, and the Associated Press. With over 20 patents and over 90 research articles, he is known for research in Web and online social sites, and the effects of social signals on user behavior. For example, he led a group of researchers at PARC to understand the underlying mechanisms in Wikipedia. He has also worked on information visualization, computational molecular biology, ubicomp, and recommendation/search engines, and has won awards for both teaching and research. In his spare time, Ed is an avid photographer and snowboarder.

Virtual Reality and Telexistence


Abstract

Virtual reality (VR) captures the essence of reality and is effectively real. VR can provide a basis for technology that enables humans to experience events and to act in a computer-synthesized environment as if they were in a real environment, while augmented reality (AR) seamlessly integrates virtual environments into real environments to enhance the real world.

Telexistence is a concept that frees humans from the restrictions of time and space, thereby allowing them to exist virtually in remote locations, as well as to interact with remote environments that may be real, computer-synthesized, or a combination of both.

This keynote reviews recent advancements in VR, AR, and telexistence with a special emphasis on retroreflective projection technology (RPT), such as optical camouflage and Repro3D, a mutual telexistence system called TELESAR IV, TELESAR V for achieving haptic telexistence, and a telexistence wide-angle immersive stereoscope (TWISTER) with a full-color autostereoscopic display and a 360-degree field of view.

Speaker's Brief Bio

Susumu Tachi received his B.E., M.S., and Ph.D. degrees in mathematical engineering and information physics from the University of Tokyo in 1968, 1970, and 1973, respectively. He joined the Faculty of Engineering of The University of Tokyo in 1973, and in 1975, he moved to the Mechanical Engineering Laboratory, where he served as the Director of the Biorobotics Division. From 1979 to 1980, Dr. Tachi was a Japanese Government Award Senior Visiting Scientist at the Massachusetts Institute of Technology. In 1989, he rejoined The University of Tokyo, and served as Professor at the Department of Information Physics and Computing till March 2009. He is currently Professor Emeritus of The University of Tokyo and Professor of Robotics and Virtual Reality at Keio University, Japan.
