Interactive Media Visualization

In this talk, I will focus on three projects related to the interactive media visualization including Dynamic Media Assemblage (IEEE TCSVT 2013), SmartPlayer (ACM CHI 2009), and Outside-In (ACM UIST 2017). Dynamic Media Assemblage is a new presentation and summarization method for images and videos on a 2D canvas. Instead of using the keyframes of the videos to generate a still image summarization, our method allows the videos to play simultaneously on the canvas while utilizing the limited space efficiently. This technique uses an efficient iterative packing algorithm, and as a result is well-suited for interactive manipulations of media files within the assemblages in real-time, such as insertion, deletion, and rearrangement. SmartPlayer is a new video interaction model called adaptive fast-forwarding to help people quickly browse videos with predefined semantic rules. This model is designed around the metaphor of "scenic car driving," in which the driver slows down near areas of interest and speeds through unexciting areas. Outside-In is a visualization technique which reintroduces off-screen regions-of-interest (ROIs) into the main screen as spatial picture-in-picture (PIP) previews. The geometry of the preview windows further encodes a ROI’s relative location vis-a-vis the main screen view, allowing for effective navigation. Two applications are demonstrated for use with Outside-In in 360-degree video navigation with touchscreens, and live telepresence. Short Bio Bing-Yu Chen received the B.S. and M.S. degrees in Computer Science and Information Engineering from National Taiwan University, Taipei, Taiwan, in 1995 and 1997, respectively, and the Ph.D. degree in Information Science from The University of Tokyo, Tokyo, Japan, in 2003. He is currently a Professor with Department of Information Management, Department of Computer Science and Information Engineering, and Graduate Institute of Networking and Multimedia of National Taiwan University (NTU), and also an Associate Director with the NTU IoX Research Center (formerly Intel-NTU Connected Context Computing Center), an Associate Dean and EiMBA Director of the NTU Management College, and the Director of the NTU Creativity and Entrepreneurship Program. He was a Visiting Researcher and Professor at The University of Tokyo in 2012 and 2016. His current research interests include Human-Computer Interaction, Computer Graphics, and Image Processing. He is a senior member of ACM and IEEE. He has been the Chair of ACM SIGGRAPH Taipei Chapter since 2015, the Executive Supervisor of ACM SIGCHI Taipei Chapter since 2016, and a steering committee member of Pacific Graphics since 2011. He is also General Co-Chairs of Pacific Graphics 2017 and ACM MobileHCI 2019. Both will be held in Taipei, Taiwan.
