Hi all! I just finished developing a small project that allows to route the pen/stylus data from any pen-enabled Android device to a Linux host pc with a focus on low-latency for the best drawing experience.
I was motivated by the HUMAN tutorial here on CGCookie, wanting to hand draw my texture maps and having a pen enabled Onyx Boox Note Air 2 just teasing me a few inch away. The Android+Linux the solutions I found thus far had numerous issues that would make them unusable for such use-case (high latency, high pressure sensitivity such that it is impossible to move the pen-cursor without triggering a draw, etc.) and this is why I decided to write my own.
The app still is in early beta stage but I would really appreciate to get feedback from would-be early adopters, especially from an art-driven community like the current one. The project can be found at:
https://github.com/androidvirtualpen/virtualpen
It is free to use (under a GPL V3 license) and should be easy to install on many linux distributions - this is an aspect I'm quite eager to test out.
Thank you so much if you're willing to experiment with it; in hope some of you can find it useful. Cheers!
