By itself, it seems like a rather funny party trick, but the applications may be more serious as shown in one of his self replies where a resume can silently influence GPT to rate the applicant highly.

Here is an open source driver that has been made that supports Wacom and Huion tablets https://github.com/hawku/TabletDriver

These were made to reduce input latency to increase performance in a rhythm game called "osu!"

Now, if only someone could make Wacom drivers that make the Wacom touch functionality interface better with Photoshop and friends, rather than just handing keyboard shortcuts to them. Somehow, that's the best Wacom has managed to do, which makes those features effectively unusable in the very apps those tablets are most commonly used...

Wow, thanks. Mentioning osu! will probably cost me a few hours after work.

Never thought of using a tablet for it, but I am so going to try that!

Thank you.
