Designing Networked Graphics Systems for Fully Mobile Hyperrealistic Telepresence
Speaker: Kyungjin Lee Seoul National University Title: "Designing Networked Graphics Systems for Fully Mobile Hyperrealistic Telepresence" Date: Thursday; 7 March 2024 Time: 11:00am - 12 noon Venue: Room 2405 (via lift 17/18), HKUST Abstract: Hyper-realistic telepresence is a futuristic platform that seamlessly integrates physical and virtual realities. It involves i) creating a realistic digital representation of the real world through precise capture and three-dimensional (3D) reconstruction, ii) sharing the representation with multiple users, and iii) providing seamless and immersive interactions. By making this platform accessible to everyday users, we can revolutionize our lives and open up new possibilities. Long-distance couples and families can feel like they are living, eating, chatting, and going on walks together as we would in our daily lives. In this talk, I will introduce a holistic software system design approach towards building such a platform. Realizing this platform entails multiple challenges, including streaming gigabytes of 3D data over the wireless network and the heavy computational overhead of generating, compressing, and rendering hyper-realistic 3D content on resource-constrained mobile devices. The systems I built tackle these challenges with end-to-end system architecture design based on fine-grained workload characterization and novel cross-layer and user-aware optimization methods. ****************** Biography: Kyungjin Lee is a Ph.D. candidate in the Computer Science and Engineering Department at Seoul National University.
