How to refer an gameobject as "THIS" or "THAT"

[Efe-Oral]

I am working on a real time VR application where I want to look at a game object and refer to it as "THIS" or "THAT". How do I achieve this functionality? At first, I thought of adding the looked game object's name alongside with the natural language user prompt to send it to LLM. But that was a bit unstable. So do you have any idea for a more reliable method to address game objects in VR setting as "THIS" or "THAT" without having to specify its name?
