Augmented Reality Dialog: Sharing a mental picture during a conversation

There is a really deep idea here but I only know it from an example.

Suppose a customer wants to talk to someone about an abutment design. They have the conversation and can agree and then share a sketch of the abutment. The design sketch does not update during the conversation but rather the designer renders the sketch afterwards and turns it around as quickly as possible to show the customer.
Now suppose that rather than a designer, the customer is interacting with a chatbot that could perform the rendering automatically as the customer speaks, to confirm an understanding of what was said. Then this would be like the customer having a conversation (in this case with an automated assistant) and seeing or sharing the mental picture as part of the conversation.

With the possibilities of Augmented Reality (AR) and Virtual Reality (VR) these days, it is not too far a leap to imagine two people conversing this way and using headsets to display a shared concept formed during the conversation. Unlike a game the view updates per the conversation not per actions and the scripted scenario of a game. We'll call this Augmented Reality Conversation - as if it existed.
