Associate Professor
Co-director, Image & Pervasive Access Lab (IPAL)

Ph.D. (Computer Science, Cornell University, 2001)
B.Sc. (Computer & Information Sciences, National University of Singapore, 1996)

Wei Tsang received his B.Sc. (Hon.) degree in 1996 from the Department of Information Systems and Computer Science at NUS (now NUS Computing), and his Ph.D. in Computer Science from Cornell University, Ithaca, New York, in 2001. He spent a year as a postdoc fellow at Berkeley Multimedia Research Center in U.C. Berkeley after the completion of his Ph.D., before returning to join NUS Computing as a faculty member. Wei Tsang’s research interests fall under the general area of interactive and networked multimedia applications. His current research focuses on volumetric video streaming, networked virtual environments, and cloud gaming systems. He is also keen in building multimedia and intelligent systems that contribute to better wellness and healthcare for all.

RESEARCH PROJECTS

DroneBuddy: Drone as a Companion for People with Visual Impairments

Drones has potential as assistive devices for people with visual impairments (PVI), for tasks such as locating personal items. The DroneBuddy project aims to develop interaction techniques, for a PVI to interact with and customize a drone equipped with programmable APIs to perform a personalized task.

DesCartes WP4: Human-AI Collaboration

WP4 focuses on how humans can interact with AI to (i) bring humanity aspects that cannot be computationally modeled into AI systems and algorithms, forming a hybrid AI with human interaction at its core, and (ii) allow hybrid AI to augment human perception and cognition (especially assisting humans in decision-making). Within this WP, we propose to develop interaction and visualization techniques
