So doesn't seem specific to Apple hardware.

The only thing "Apple" here is that it's not exposed as a public API.

No, it's a different method.

		Author here. We checked for APIs like this at the time, but since approximately every laptop has a webcam, the cv approach is much more accessible. It would be a fun rewrite though; I’m sure polling this would be a few orders of magnitude more efficient. There was definitely lag if you ran the app on a very underpowered machine which did impact the “playability” of the velocity parameter.

Apple goes much further than not offering an API: https://www.forbes.com/sites/jaymcgregor/2023/10/11/genius-n...
