AI Perception vs EQS queries

Don’t understand conceptual and use cases difference between AI Perception and EQS queries.Explain please?

I second this. It would be great if we can have some use cases and simple scenarios briefly explained.

Think of perception as a short term memory of things…actors perceived are tracked by the bot as long as they stay within the range of the perceiving sense.
With EQS, your bot knows where everything is in the environment as it acquires them. They stay in memory no matter where the AI bot moves.
