Haptics and Automatic Authoring of Its Content


Providing rich and immersive physical experiences to users has become an essential component in many computer-interactive applications, where haptics plays a centrol role. However, as with other sensory modalities, modeling and rendering good haptic experiences with plausible physicality is a very demanding task in terms of the cost associated with modeling and authoring, not to mention the cost for development. No general and wide-used solutions exist yet for that; most designers and developers rely on their in-house programs, or even worse, manual coding. This talk will introduce the basic concepts of haptics and the research conducted by the speaker in order to facilitate the authoring of haptic. The latter will consist of three parts: 1) Manual authoring paradigms for easier and faster synthesis of vibrotactile effects; 2) Automatic synthesis algorithms of vibrotactile effects from video and sound; and 3) Automatic synthesis algorithms of motion effects from from video and sound.


Seungmoon Choi, Ph.D, is a Professor of Computer Science and Engineering at Pohang University of Science and Technology (POSTECH) in Korea, also with a joint appointment of Creative IT Engineering. He received the BS and MS degrees in Control and Instrumentation Engineering from Seoul National University in 1995 and 1997, respectively, and the PhD degree in Electrical and Computer Engineering from Purdue University in 2003. His main research area is haptics, the science and technology for the sense of touch, as well as its application to various domains including robotics, virtual reality, human-computer interaction, and consumer electronics. He received a 2011 Early Career Award from the IEEE Technical Committee on Haptics. He serves/served in the editorial board of IEEE Transactions on Haptics, IEEE Robotics and Automation Letters, Presence, and Virtual Reality. He was the general co-chair of the IEEE Haptics Symposium in 2014 and 2016 and the program chair of the IEEE World Haptics Conference 2015. He was a co-chair of the IEEE Technical Committee on Haptics from 2009 to 2011. He has published more than 150 peer-reviewed international papers, 90 domestic papers, and 20 patents, with many best paper and best demonstration awards from premium international conferences. His specific research interests lie on haptic rendering and perception, both in kinesthetic and tactile aspects. His basic research has been applied to mobile devices, automobiles, virtual prototyping, and motion-based remote controllers. He is a senior member of the IEEE and a member of ACM, TCH, and Eurohaptics Society. A full CV of Dr. Choi is available for download at www.postech.ac.kr/~choism.
