The implemented collaboration functionality enables participants in a shared AR session to create and edit virtual objects by supporting remote, multi-modal visualization and interaction in 2D, 3D and AR. Additionally, we demonstrate our ongoing efforts in exploring video-based interaction with remote AR scenes. The implemented communication architecture and feature set was developed for Apple iOS devices based on the existing general-purpose room-scanning app ARchi VR. The prototype application demonstrates the feasibility and the potential of multi-modal collaboration in AR.enAugmented Reality (AR) Real-time Remote CollaborationText/Conference Paper10.1145/3603555.3609310
