Abstract
Augmented and Virtual Reality promises have yet to be met, it remains inhibited by an average user experience. Limits in local processing (headset/handset), form factors and display/optical limitations have kept the technology from reaching its full potential. 5G and Cloud-based processing offers the potential to improve performance, comfort/ergonomics, mobility and QoE barriers. Our research demonstrates a methodology for assessing AR/VR QoE performance on mobile networks and how 5G and cloud-based processing create a better user experience, accelerating the growth of this nascent market. QoE models are proposed for AR/VR which define the key quality indicators (KQIs) for each AR/VR application and we correlate the KQIs performance to network KPIs. The study demonstrates how typical LTE KPIs are insufficient to deliver an immersive QoE for AR/VR. Finally, we quantify the increase in QoE with 5G and edge cloud based on the expected KPI performance improvements. The proposed AR/VR QOE models are evaluated in the context of the enhanced network performance with 5G and Edge Cloud deployment.
