InstantCopresence: A Spatial Anchor Sharing Methodology for Co-located Multiplayer Handheld and Headworn AR

We proposed a simple yet instant methodology InstantCopresence for synchronizing co-located multiplayer AR sessions across handheld and headworn devices. This process makes multiplayer setup effortless, enabling users to scan another device’s QR code and instantly enter a shared mixed reality experience, without the need for an internet connection or previous spatial map scans, thanks to the local networking technology behind AirDrop. We further showcased the capabilities of our method by demonstrating an asymmetric role-playing multiplayer game called Dragon Hunting, supporting up to 8 players with diverse roles, thus highlighting the potential and simplicity of our proposed methodology.
