"gain insights into how people and things move throughout their physical spaces"
People: mostly one foot in front of the other foot, through doorways, up and down stairs or levators (lifts) and I understand occasionally out of windows.
Chaps in wheelchairs or other mobility aids pretty much the same except the foot bit and the windows. Bloody hard to hurl an occupied wheelchair through a window, errr... or so I believe.
Things: mostly because a person has carried, wheeled or otherwise conveyed the thing although in these workplaces thrown or a good bit of welly with the bother boots is equally likely.
The ultimate consequence of this nonsense is the complete dehumanization of people into things and the even more unthinkable that follows.
Terry Pratchett has Granny Weatherwax clearly stating "Sin [...] is when you treat people as things. Including yourself. That’s what sin is*."
* From an exchange in Carpe Jugulum between Granny and the Omnium Mightily Oats:
“It’s a lot more complicated than that . . .”
“No. It ain’t. When people say things are a lot more complicated than that, they means they’re getting worried that they won’t like the truth. People as things, that’s where it starts.”
“Oh, I’m sure there are worse crimes . . .”
“But they starts with thinking about people as things . . . ”
