active stylus position defects #302

Thanks for the report! Do these defects also occur when you disable the video stream? Specifically, how does the debug overlay from Android compare to the blue lines from Weylus? You could also inspect how the pointer events that arrive at your computer look like using: $ WEYLUS_LOG_LEVEL=TRACE ./weylus 2>&1 | rg "PointerEvent.+x: (\\d.\\d+), y: (\\d.\\d+)" -or '$1 $2' > data &
# run once the first pointer events have been recorded
$ gnuplot -p -e "while (1) { pause 0.5; plot 'data' using 1:2 with linespoints lc rgb 'black' ps 1 title '' }"Also, make sure to use builds from latest master (or build Weylus yourself): https://github.com/H-M-H/Weylus/actions/runs/11405365806 Finally, please attach the log output of
I suspect a native app could work better as browsers tend to be quirky, especially around pens. Actually, I am looking into writing such an app, but no promises :). |
There are no such defects when video is disabled as shown in the screenshots below. But Weylus skips points which is bad too.
|
Which programming language are you planning to use? |
|
I am considering flutter + native code (Kotlin) where necessary. But I am not sure if I can justify working on this without getting paid. Therefore, said app probably won't be open source for now. |

Below is a stroke. I'll make more stroke to have more data. I plotted the Weylus log with my program.

^CI slightly modified the capturables list feature, added printing of additional log messages, and compiled Weylus in the debug mode. |

What would an android app need to do? I just started using Weylus and I'm absolutely loving it. If possible I would like to contribute. |
|
Does this have the potential for lower latency? i.e. does Browser overhead naturally result in higher latency that a dedicated app would reduce? |
First it would need to connect to Weylus via websockets, request a window or a screen to record and send input events to, see https://github.com/H-M-H/Weylus/blob/master/src/protocol.rs for the protocol. Then Weylus will start sending a video stream.
There are several things that introduce latency. Most importantly:
For the latter two points there is little customization that can be done with browsers and leaves not much room for improvement. It is possible that a dedicated app could result in lower latency. If there are more questions about an app, please see #136 or open a discussion here: https://github.com/H-M-H/Weylus/discussions. |

When an active HUAWEI M-Pen lite stylus is used on a HUAWEI MediaPad M5 lite tablet in the Chrome webbrowser, stylus positions are transmitted with defects shown in the screenshots below. The blue line with the red dots was produced by Android when the option Settings, System, Developer options, Input, Pointer location is enabled. The black line is what was drawn in GIMP on the desktop where the Weylus executable was running.
There are no such defects when drawing with a capacitive stylus as shown in the screenshots below.
There are no such defects when drawing in the Squid application on the tablet (without Weylus).
Would such defects occur with a native Android application communicating with the Weylus executable?
