题目: Supporting Mobile Virtual Reality with the Mobile and Edge Cloud
Virtual Reality (VR) fundamentally improves the user’s experience when interacting with the virtual world, and could revolutionarily transform designs of many interactive systems. However, providing VR from untethered mobile devices is difficult due to their limited local resources and computing capabilities, which prevent VR from being widely available anytime and anywhere. In this talk, I will present our recent research work that removes such constraints on the mobile VR performance by leveraging the power of the mobile and edge cloud. First, we experimentally investigated and verified the redundancy of rendering VR frames for different users running the same VR application, and further developed a mobile system framework that supports multi-user mobile VR over resource-constrained edge cloud by adaptively reusing the rendered VR frames. Second, we further augmented the mobile VR’s ability of sensing and responding to the user’s inputs, by enabling remote access to heterogeneous wearable sensing devices and hand-held VR controllers through a generic mobile cloud middleware. This talk will also discuss my ongoing work on other avenues of improving the performance of mobile VR.
