Putting myself in the shoes of a qa for a second...

What is the cheapest way for me to trigger a false positive on such a detection device?

And what can we do about it?

Rinse and repeat until the cheapest cost exceeds a standard pair of smart glasses.

Before putting yourself in the mind of QA, you have to be 100% sure on what the goals and priorities of the product is supposed to be in the first place.

Only a subset of use potential cases will be worried with false positives, but this approach says to drive the cost greater for all potential use cases.

Bluetooth packets similar to smart glasses and IR filters used by a popular brand should probably be enough.
