It's not rocket science, these people aren't even all that clever. It's going to be some kind of camera (maybe lidar) and microphone, there's nothing else it can be — you need to put something into AI to get something out of it.
It'll probably be some goofy 180/360 degree camera — phones aren't really designed to be omnipresent so the form factor isn't ideal for the always-on nature of AI they're trying to reach.
