Multi Projector based Spatially Augmented Reality

Series: Department Seminar

Speaker: Gopi Meenakshisundaram, Professor, UC Irvine

Date/Time: Apr 21 11:00:00

Location: CSA Seminar Hall (Room No. 254, First Floor)

Abstract:
Virtual/Augmented Reality headsets have transformed the way people experience different types of data, especially in gaming and entertainment. While headset based VR/AR can provide enhanced interactions for remote collaborators, for co-located collaborators, it can be restrictive and isolating. In their current form factor, headsets can be cumbersome, sometimes causing fatigue with long-duration use.

Spatially Augmented Reality (SAR) using multi-projector displays aims to bring the surround or large field-of-view (FOV) collaborative experiences out of the VR/AR headsets by merging digital content from multiple projectors with the physical environment around the user(s). The vision is to use multiple projectors to project digital imagery on everyday surfaces surrounding one or more users and to employ cameras to understand the display surface and projected content for correct merging of the physical with the virtual. Users can be tracked by the same cameras to provide dynamic perspective views of 3D virtual environments projected on the surfaces around the user.

This talk will present the key components of multiprojector displays developed at UCI, focusing particularly on advanced computer vision techniques to bring this vision into fruition.

Speaker Bio:
Gopi Meenakshisundaram is a Professor of Computer Science in the Department of Computer Science, and from 2016-2024, he was the Associate Dean at the Bren School of Information and Computer Sciences at University of California, Irvine. He received his BE from Thiagarajar College of Engineering, Madurai, MS from Indian Institute of Science, Bangalore, and PhD from University of North Carolina at Chapel Hill. His research interests include geometry and topology processing in computer graphics, projector-camera systems, and biomedical visual data processing. His work on representation of manifolds using single triangle strip, hierarchyless simplification of triangulated manifolds, use of redundant representation for big data for interactive rendering, and biomedical image processing have received critical acclaim including best paper awards in two Eurographics conferences and in ICVGIP. He is a gold medalist for academic excellence at Thiagarajar College of Engineering, a recipient of the Excellence in Teaching Award at UCI, a Link Foundation Fellow, and Senior Member of IEEE. He served as the program co-chair and papers co-chair of ACM Interactive 3D Graphics conference, area chair for ICVGIP, program co-chair for International Symposium on Visual Computing, an associate editor of the Journal of Graphical Models, a guest editor of IEEE Transactions on Visualization and Computer Graphics and in the steering committee of ACM Interactive 3D Graphics.
