HMH

Thanks for giving it a try! If you are on Linux you could try to select a window and check if making it smaller still results in lags.

Unfortunately the ability to playback videos via MSE API with low latency seems to vary quite a bit from device to device. You could also try an older release (v5.*). Those work by repeatedly sending PNGs and updating an image tag, actually the gif in the Readme is from that version. If this works better for you I will probably add it back as fallback in case video playback is to slow.

Hi HN, I created this program out of my personal need to be able to do some handwriting on my Linux system. I know, I could just have bought a graphic tablet but as I already have a tablet with the necessary hardware for note taking around I was unwilling to do so. And after quite some fruitless search for a solution to this problem Weylus (= Web + Stylus) was born.

It is written mostly in Rust, some C and a tiny bit Typescript and works by serving a webpage that uses the browser API to capture pen, touch and mouse events from the tablet. Additionally the desktop or a selected window is captured and encoded to a video stream via ffmpeg. This stream is played in the browser using the Media Source Extensions API.

This should also run on macOS and Windows but with very limited features.

The review mentions that the screen is a bit small for all of Krita and suggests that using something like a big iPad probably provides a better experience.

As this is only about Android I thought of promoting my take on this problem. In fact I released a small program I use to take handwritten notes via iPad on my Linux system just a few weeks ago. It works on both Android and iOS and basically turns these devices into graphic tablets. You can take a look at: https://github.com/H-M-H/Weylus

I turned my iPad into a graphic tablet for my Linux system as I was in need of taking handwritten notes there. I posted a Show HN a few days ago but it did not get much traction [1]. You can have a look at it here: https://github.com/H-M-H/Weylus

One thing I am not too happy with is streaming the screen back to the tablet, so you can see what you'r doing. Currently this is just a PNG stream over websockets, if you got better ideas I am all ears!

Assuming this to be the reply to my question:

I probably was a bit imprecise but what I want to know is if there is a way to apply this to data that are possibly in a superposition and overlapping meaning that you only see the sum of the events. For example if one wants to analyze a changing electric or magnetic field.

Nevertheless, the points you mentioned are something I did not think about at first, interesting once again.

Thanks, very interesting!

So what about superpositions of events i.e. two motifs overlapping, anyone any thoughts on that?

I guess this just means a lot more swiping of observed patterns over the timeseries and thus being somewhat slow.
