In this position paper, we propose a research infrastructure, dubbed CoMIC, to fill this critical gap, by offering a collaborative, visual-first, and hologram-based computing space and a QoE-driven, multi-site, and immersive communication framework. With its rudimentary prototype, we demonstrate the effectiveness of CoMIC through a case study of multi-user volumetric video streaming over mmWave. We conclude this paper with a discussion of numerous unique opportunities that can be enabled by CoMIC. 收起
