Keynote Abstract

Despite over 30 years of research, 3D gestural interfaces still remain a challenging problem in achieving highly accurate and robust recognition systems that users want to adapt and use regularly. In this talk, I will discuss my work in this area, focusing on the last 10 years of research projects that aim to increase the number of gestures one can accurately recognize at any one time as well as the exploration of what it means to have an ecologically valid recognizer evaluation. I will also present lessons learned along the way and areas for future work in this exciting and challenging research area.

Joseph J. LaViola Jr. is the Charles N. Millican Professor of Computer Science and directs the Interactive Computing Experiences Research Cluster at the University of Central Florida. He is also an adjunct associate research professor in the Computer Science Department at Brown University and the former director of the Modeling and Simulation graduate program at UCF.

His primary research interests include pen- and touch-based interactive computing, 3D spatial interfaces, human-robot interaction, multimodal interaction, and user interface evaluation. His work has appeared in journals such as ACM TIIS, ACM TOCHI, IEEE PAMI, Presence, and IEEE Computer Graphics & Applications, and he has presented research at conferences including ACM CHI, ACM IUI, IEEE Virtual Reality, and ACM SIGGRAPH. He is also the lead author on the second edition of 3D User Interfaces: Theory and Practice, the first comprehensive book on 3D user interfaces.
