Multi-user and collaborative AR applications pose several challenges. The expected
user experience requires accurate pose information for each device and precise synchronization
of the respective coordinate systems in real-time. Unlike mobile phones or AR glasses
running on battery with constrained resource capacity, cloud and edge platforms can
provide the computing power for the core functions under the hood. In this paper,
we propose a novel edge cloud based platform for multi-user AR applications realizing
an essential coordination service among the users. The latency critical, computation
intensive Simultaneous Localization And Mapping (SLAM) function is offloaded from
the device to the edge cloud infrastructure.
