Mobile Augmented Reality with Federated Learning in the Metaverse
share
The Metaverse is deemed the next evolution of the Internet and has received much attention recently. Metaverse applications via mobile augmented reality (MAR) require rapid and accurate object detection to mix digital data with the real world. As mobile devices evolve, they become more potent in computing. Hence, their computational resources can be leveraged to train machine learning models. In light of the increasing concerns of user privacy and data security, federated learning (FL) has become a promising distributed learning framework for privacy-preserving analytics. In this article, FL and MAR are brought together in the Metaverse. We discuss the necessity and rationality of the combination of FL and MAR. The prospective technologies that power FL and MAR in the Metaverse are also identified. In addition, existing challenges that prevent the fulfilment of FL and MAR in the Metaverse and several application scenarios are presented. Finally, two case studies of Metaverse FL-MAR systems are demonstrated.
