Thanks @ajay-sh21 can you please give some more info on the situation you see this needed? And to what degree of granularity?

Here idea is to understand the context by knowing relative vertical position, for example if the object is lying on the floor, on the table or on top of the almira, one could get the hintthis info from the virticle position i.e. "0 feet from the ground", "3 feet from the ground" or "10 feet from the ground"

Another important information to know would be the size of the object in terms of x, y and z axis, for example, while there is a table in the virtual room, if it would be possible to figure out the size of the table, i.e. "Table, 8feet long, 3 feet wide and 3 feet high", this may be useful to know the arrangement of the room with respect to the size of the wall behind it i.e. "Wall, 12 feet high and 20 feet long".

That being said, it may be not always necessary to know the virtical position or size, hence it is expected to this get passed only when user demands it or could be appended to the name of the object in case it is crucial to carry out the functionality effectively.

Thanks @ajay-sh21 for replying to my NEEDSINFO request. We will discuss further on an upcoming call.

Discussed again in RQTF we will add an update on the need for filtering and the ability to query items and content for more details. Thanks @ajay-sh21
