I've just been watching her recent talk. I noticed she appears to change slides with a wave of her wand. Is there an known piece of hardware one can purchase to do this? I tried googling, but trying to find the specific result I'm interested in amongst all the blog spam garbage related to powerpoint is beyond me. Even googles own AI couldn't help. Sad times!

She might be doing some OpenCV/MedaPipe gesture tracking? There's lots of tutorials out there and it's not super difficult to get some basic gesture tracking going on your laptop.

Purchasing one has been illegal since 1863, but the technology typically used is a human assistant, although the signal is usually more subtle.

  Who can forget 1863. The year BigMagic ruined the fun for everyone.

    While I originally understood it the way you did, I think they were referring to this: https://en.wikipedia.org/wiki/Emancipation_Proclamation https://en.wikipedia.org/wiki/Emancipation_Proclamation

Ug… a person is watching and clicking for her when she does that?

Is Leap Motion still a thing?

Maybe some ESP32 or other MCU and accelerometer ? That should comfortably fit into a magic wand.

In this case there's probably a human doing the slides, but smart watches have apps that can control slideshows in a variety of ways. There's at least one WearOS app (WowMouse) that does some gesture based presentation control.
