报告题目:Reality Check of Metaverse: A First Look at Social Virtual Reality Platforms


Metaverse has grasped the news headlines recently. While being heavily advocated by the industry, there are great interests from academia as it demands various technological support from both hardware and software research. There has been an extensive visionary discussion of Metaverse lately, but there are few studies on its technical challenges and user experience in practice. To fill this critical gap, we take a first look at Workrooms, which was recently released by Meta (a.k.a. Facebook), and AltspaceVR from Microsoft, two representative social virtual reality (VR) platforms that are viewed as early prototypes of Metaverse. The overarching goal of our study is to gain an in-depth understanding of the current state of the Metaverse and identify potential issues for improvement. Through extensive measurement studies, we dissect the underlying network support and demand of Workrooms and AltspaceVR. Our investigation reveals several interesting findings. For example, Workrooms utilizes different network flows to transmit virtual content and real-time multimedia content separately. This might be a principled approach that should be adopted in general. On the other hand, the current design of both Workrooms and AltspaceVR may face imperative scalability challenges that should be addressed in any large-scale Metaverse platform.

报告题目:Virtual and Augmented Reality Consultation with a WiM


Communicating knowledge regarding three dimensional complex matter such as for medical procedures is not a trivial task. However, virtual and augmented reality can help users to create and understand 3D information more intuitively. We present our research in the medical teleconsultation system “ArtekMed” and focus on advanced interaction techniques for 3D consultation, in particular, the methods named Magnoramas and Duplicated Reality. Both methods can be understood as World-in-miniatures; however, focus on magnifying, rather minifying 3D content.


Kevin Yu is a 4th year Ph.D. student at the Technical University of Munich, Germany. His personal goal is to augment current health care with modern advancement using innovative technology. His primary interest is in medical augmented reality and 3D user interfaces.
