Embed jitsi in the webpage: that should let us know when someone leaves a room

[katjaq]

Here's a simple repo showing how to embed many jitsies: https://github.com/r03ert0/manyjitsis

The code is basically:

const domain = 'meet.jit.si';
  const {offsetWidth: width, offsetHeight: height} = document.querySelector("#jitsi");
  const options = {
    roomName: 'OpenForumMainRoom',
    width, height,
    parentNode: document.querySelector('#jitsi'),
    configOverwrite: {
      startWithAudioMuted: true
    }
  };
  let api = new JitsiMeetExternalAPI(domain, options);

which supposes there's a div with id="jitsi".

@katjaq I ended up doing this to detect for someone closing the window

function openJit(url, number) {
    wss.send(JSON.stringify({action: "jit", id: number}));
    let child = window.open(url, "jit"+number);
    let timer = setInterval(()=>{
        if(child.closed) {
            wss.send(JSON.stringify({action: "jitclose", id: number}));
            clearInterval(timer);
        }
    }, 1000);
}

This seems to work.. but I will try the JitsiMeetExternalAPIapproach if it doesn't work still. Thank you for letting me know about this API!

awesome! we'll integrate that in brainweb as well. We started exploring using jitsi's data channel for allowing feedback (many other things could be done with it!). It would be wonderful if you guys were willing to keep pushing this with us after the OHBM meeting <3

I think it was done by @soichih, so we are all set ! ;)

[r03ert0]

awesome!! \o/

Hello datafriends! we did a thing with @katjaq using your wss & data :)
We wanted to have an easier way of seeing who's connected and not. We made a screen with squares showing room occupancy (we also added the emoji feedback :p). Hope you'll like it! <3

That is really cool. Do we know anything about the number blocks? Could we split it by category to make it easier to narrow down which green squares to check out?

Or possibly add a search filter that will reduce the blocks to matching posters?

[r03ert0]

yes! we could change the background colour to reflect the category, or add a filter base on the keywords. I'll try to recycle brainweb's community graph viewer to make a network of similar posters (and whether they are active or not :D)

abstracts.json already has bag of words for each abstract - might help to relate?
Coming from your ui to the room talks to soichis backend to announce count, right?
When you are ready (now?) we should add a list of alternative web UIs on top of our page.

[r03ert0]

now is good!

yes, I talk to @soichih's websocket, so that it doesn't matter which UI people use to connect, the counts will be the same :)

(checking abstracts.json, how cool!)

BTW, forgot to mention open project which I hoped would be our gather town but it is one man effort AFAIK, but might give good ideas etc: https://github.com/capnmidnight/Calla

I will reopen since we last discussion here...
