Use your tablet as graphic tablet/touch screen on your computer. - H-M-H/Weylus

Weylus lets you use your tablet as input device on your computer. The screen is mirrored and things like pressure sensitivity as well as multi touch is supported. Like this you can easily start drawing or handwriting on your computer using your tablet.

Weylus only needs to be installed on your computer, NO apps are required! You can just connect your tablet to your computer via browser.

    Looks like there’s a lot of latency

      Some numbers I can give you:

      • X11 Screen capture: ~1ms
      • VAAPI video encoding + capturing: ~12ms
      • NVENC video encoding + capturing: ~10ms
      • End to end video latency over WiFi to iPad: ~50ms (Measured by taking a photo of both screens with a timer running)

      Tested on a Dell XPS 15 with a screen resolution of 1920x1080.

      On Android devices you can reduce the latency brought by WiFi by using USB tethering or adb, see the FAQ.

          Yes you are right, input lag is definitely lower. I don’t have numbers though as it is kinda hard to measure.

    I’m curious what are you drawing in. As I understand it’s not some part of weylus?

    • HMHOP

      Yes, that’s correct. Weylus itself is only responsible for input and screen mirroring. The program you can see in the GIF is Xournal++.

        Now I saw that you wrote about that in your README.md. You did great job on that btw. There is ton of really usefull and important information. Big thanks for that :)

    It reminds me of spacedesk, a tool wich you can use to turn your phone into a 2nd display, with touch imput

    • HMHOP

      Yes, Weylus is very similar but open source and works on Linux :)
