A.2  Use Case 17: AR remote advertising  p. 105

Use Case Name
AR remote advertising
Description
Compared with the use cases described in Annex A.8 and Annex A.12 of TR 26.928, this use case emphasizes that the shared video contents between two parties of a session are from a third party. Furthermore, the shared video contents may be 3D model objects, 360 degree and even free-viewpoint in order to help people have more interactive and immersive experiences.
For example, a real estate salesman initiates an audio call to a client by his smartphone to advertise houses remotely. The real estate salesman can request some video contents which are restructured 3D objects for houses to be sold/rent in advance from the third content provider and then switch a video call. The real estate salesman and the client can receive the video contents from the third content provider simultaneously. The real estate salesman can introduce via audio while he rotates the model. At the same time, the client can hear the introduction and see the rotational model via the touch-screen of his smartphone. And vice versa, the client is able to ask what he cares via audio while he is marking in different colours on the shared model, the client can hear the questions and see the colourful marks in real-time.
In an extension to the use case, if the video content is free-viewpoint and embed some 3D objects representing furniture, the client wearing an AR-glass is able to see layouts and furnishings of the virtual houses which can rendered following his posture. It seems that the client is just inside the advertised and virtual house, and is able to walk around different rooms (e.g., dining room and living room). Furthermore, the client can draw a 3D object for a small couch back and forth in the living room using his hand. In addition, the real estate salesman can insert his 3D animated model in the virtual house and it can move following the view scope of the client as if he is just beside the client and introduces the house to the client.
In another extension to the use case, the client can invite his friend to see the virtual house together. They can see it from their respectively viewpoint. They can also walk around the virtual house when wearing an AR-glass and communicate with each other via audio.

Preconditions
<provides conditions that are necessary to run the use case, for example support for functionalities on the end device or network> the devices with the following features
  • Support for conversational audio and video
  • Support for receiving the video contents from the third party
  • Collecting of AR actions (e.g. rotation and mark) and posture information
  • Support of depth location technologies (e.g. SLAM for AR-glasses)
the network with the following features
  • Rendering of overlying AR actions and posture information
  • Delivery of AR actions and posture information
  • Support for establishing a connection the third party
Requirements and QoS/QoE Considerations
<provides a summary on potential requirements as well as considerations on KPIs/QoE as well as QoS requirements>
QoS:
  • conversational QoS requirements
  • sufficient bandwidth to delivery compressed 2D/3D objects
  • Accurate user positioning information
QoE:
  • Synchronized rendering of overlay AR actions and posture information
  • Synchronized rendering of audio and video
  • High-quality depth video captured from both parties
Feasibility and Industry Practices
<How could the use case be implemented based on technologies available today or expected to be available in a foreseeable timeline, at most within 3 years?
  • What are the technology challenges to make this use case happen?
  • Do you have any implementation information?
    • Demos
    • Proof of concept
    • Existing services
    • References
  • Could a reduced experience of the use case be implemented in an earlier timeframe or is it even available today?
>
Enhancements in media processing for the media contents from the third party together with all kinds of AR actions and 2D/3D model objects may be performed in the network (e.g. by a media gateway) and in order to enable richer interactive and immersive experiences.
Potential Standardization Status and Needs
<identifies potential standardization needs>
  • Delivery protocol of the shared media contents from the third party
  • Standardized format and delivery protocols of AR actions and 2D/3D objects
  • Standardized format and delivery protocols of posture information
  • More than one communication channels can be setup
