Don’t interfere with somebody else’s disability aids

Don’t play with other people’s stuff without asking first, and remind other people to do the same.

Basic etiquette includes:

Some people will be more than happy to explain how their tools work, and they often contain some very sophisticated technology. (I was blown away by a demonstration of a finger-sized OCR device recently.) But it’s up to them to decide if they want to talk about it, and what to show you – ask, don’t assume.

If your attendees aren’t familiar with these rules, a reminder might be helpful.
