Our research on "Augmented Communication" aims to enhance remote communication in virtual and augmented reality through the integration of cutting-edge technologies such as machine learning, eye tracking, visual augmentation, and gesture recognition. Through this research, we have developed innovative solutions such as Visual Captions, which proactively suggests relevant visuals to aid in open-vocabulary conversations; ThingShare, a video-conferencing system that facilitates the sharing of physical objects; GazeChat, a remote communication system that utilizes gaze-awareness to represent users in 3D profile photos; and CollaboVR, a framework that enables multi-user communication in virtual reality through the design of interactive and reconfigurable layouts. Our goal is to further the state-of-the-art in real-time systems for augmented communication in VR and AR, ultimately making remote communication more universally accessible and effective.
