It's a touchpad, of course the result shows up on the laptop screen, and the user doesn't even look at the touchpad anymore, just as digital artists don't now. Honestly not sure why commenters here are acting like it's some huge deal to use a touchpad for note taking and that one has to get an iPad when there really is no need.

Wacom have been selling "pen displays" for years, at least since ~2013. You can buy a brand new one for $300.
