- HP 2-in-1 tablet/laptop
- Huion H420 graphics tablet
- Synaptics touchpad in absolute-mode
- PSP connected as a controller to a PC
- Nexus 10 over Splashtop (worked really well actually)
- Taiko no Tatsujin Wii drum
- Wiimote (with cursor tracking; didn't work to well iirc)
- Random touchscreen AIO computers inside Staples and Best Buy stores
- DIY touchpad involving a webcam and a laser (I don't recall this working well at all)
-
Scanner- Remote control over KDE Connect (horrible)
I would like to try out my dance pad one of these days; I imagine it would work decently with osu!mania if I map it DDR/ITG-style.
My main set-ups include just a KB and the H420 tablet, and my HP 2-in-1 when I want to do touchscreen. I kind of want to do something like an osu!arcade if osu!stream for Windows releases.
