A.6  Use Case 21: AR gaming  p. 117

Use Case Name
AR gaming
Description
By using AR technology, AR gaming is to apply virtual models to the real world and then provides game entertainment experience in a world of virtual-reality combination, which is difficult to experience in reality. People can interact with virtual objects controlled by game operations in the foreground of the real world. For many consumers, immersion is a key factor in their enjoyment of games, and AR can help users achieve such experiences exactly.
For example, Alice wears AR glasses at home and opens an AR golf game application. The AR glasses display a virtual sand table of golf course and golf ball through the spatial location on the floor of her house. Alice needs to use a certain gesture to hit the golf ball and make it go into the hole. Finally, the AR golf game application can calculate Alice's score.
AR gaming can also support multi-player games. Alice invites Bob and Clare to play an online AR shooting game in her living room. They wear AR glasses, log in to the AR shooting game application, select the multi-player team mode, and then they can control the shooting action through a gesture or the tethering device. The virtual target set in the shot game will appear in the living room, and have corresponding response according to their operation and display in their AR glasses. Then they can complete the game task and upgrade.

Feasibility and Industry Practices
There are some AR game demonstration examples using AR glasses.

During the 2018 World Mobile conference, China Mobile, Tencent and Huawei jointly announced the completion of AR game experimental verification based on 5G enhanced bandwidth stable delay network slice.
Potential Standardization Status and Needs
  • Network conditions that fulfill the QoS and QoE requirements
  • Architectures for computing support in the network
  • Cloud APIs for group authentication and multiuser synchronization.
  • Standardized format and delivery protocols of AR actions and 2D/3D objects
  • Standardized format and delivery protocols of posture information
  • Metadata for Spatial characteristics of the AR environment (e.g. positioning of users).
  • Rendering of overlying AR actions and posture information for virtual and real superposition
