Okay, so the talks continue.
Now we have run from clever activity,
and we'll be talking about collaborative slideshow.
Hello everyone, so collaborative slideshow.
It would be very ironic if we don't have collaborative slideshow,
and the name of the company is Colabora.
So, first of all, why we started this collaborative slideshow thing?
So, we all have been in a situation where you have joined the meeting with 40, 50, 100 people,
and your boss has started presentation,
and you are not able to see something where he is sharing the screen,
or anything he is talking about on this slide.
So, what if we could all join a document,
and the presenter can start the presentation for everyone of us,
so we can see the presentation in our compatible resolution on our screen.
So, instead of sharing entire screen on sometimes on low bandwidth,
where you can barely see pixels on the screen,
we all have been there, if you have not been there, you are very lucky one.
We are hoping on your luck when aliens attack us,
we want you to save the Earth.
But, until then, we have a feature for you.
So, what is it?
As I said, you can start presentation for everyone who has joined the document,
and whenever a presenter goes forward, backward, or plays a video,
and everything just happens on your native machine,
as if you are running the presentation.
So, on your own resolution,
and you can see every minute detail according to your screen size.
And, the feature is called present to all,
earlier it was called follow me presentation,
but someone with better English came and renamed it.
So, to show it, how does it work?
And, just in case, if you are wondering what's the feature.
So, right now, it's not me who is controlling the presentation.
It's a sharper my friend.
We are connected on through internet,
and he is controlling this presentation.
As you can see, I'm not touching anything.
He is doing everything.
So, how does it work first of all?
So, just like any simple presentation,
first of all, whenever someone wants to start the presentation,
or makes any moves, they press the key,
as supper will now press the next button.
So, our system, the presenter system,
will send the request to the server,
and then server sends response back to the system.
Now, supper will send the response.
But now, in this case, we just broadcast the same response
to everyone in the room, everyone on the document.
So, there is no extra load on the server,
but whatever we have rendered,
we send it to the everyone else in the document.
And on top of that, if you have same resolution,
we send the same slide for which we have already rendered to everyone.
But just in case, if you have different resolution,
let's the presenter is in the fork screen,
where if we send the same slides to you,
who is on the edge screen,
then you will not be able to see everything,
everything will be very small,
and we face the same problem,
which we were facing on this streaming.
So, in this case, we render specific to the screen size,
but we only render it once and send it to the everyone.
So, when very simple architecture,
nothing very complicated in this.
And on top of that, you also have a freedom to move,
let's say, if your teacher is explaining everything very fast to you,
and you are just like me who is a slow learner,
and teacher has moved to the next slide,
and you want to go back and see what is happening.
So, right now, it's me who is going to back two slides,
three slides, whatever, and then again,
there is this small button here,
where if I press that, I'll again join the leader,
the presenter, wherever they are.
It's not a bug, he moved away.
So, let's move forward,
and then you have rejoined the presentation,
so wherever the presenter goes ahead, we can go.
Now, it's another thing, because I kind of, sorry,
it's from me, we were waiting,
and the demo goods are not with me today.
But it works, it works,
and there are many things,
which curious people create problem for.
I'm sorry, I had to click.
So, on top of that, let's say,
if we are moving away from the streaming to now this document,
so there are chances that, let's say,
there are thousand people, not thousand people,
but let's say, 50 people,
100 people are joining this document,
and earlier we used to render things for everyone,
but right now, if 100 people request slide rendering,
that would overwhelm any server.
Right now, instead of rendering it for each and every view,
now we just render it once and cache it.
So, unless the document changes,
we can keep serving same slides to anyone
and everyone who joins the document,
and that's how we do it,
in terms of integration.
So, we have also integrated this feature with next cloud talk.
So, there is this video,
I was going to show off the video that this collaborative slide show
also support the video,
as of now we are out of sync.
So, unfortunately, I'll play it myself,
but otherwise, separate good played.
So, in this feature,
you can just, from the smart picker,
you can just start presentation,
and it will generate a specific link.
So, whoever has shared the link,
automatically becomes the leader,
and whoever other person joins this,
it doesn't matter, the order doesn't matter,
but the other person will always be the follower,
and the one who shared the link
will always be the leader of the presentation.
So, now, if the leader goes to the next slide,
even the follower will go to the next slide,
as you can see,
and the follower moved forward and backward,
without breaking the feature, like we did.
And, sorry.
Can the follower quickly jump back with,
yes, yes.
So, there is this button,
follow, follow presenter.
So, you can just, even if you move anywhere,
let's try, if we are still connected,
are we on the same slide?
He already closed.
So, let's try to go to the next slide again.
So, this is the integration, let's move again somewhere.
I think I might have changed to the first amendment for a second.
So, we were disconnected.
Yes, basically, if we are connected on the internet,
we will be able to, I don't have internet,
we were connected on the hotspot.
So, if you press this button,
you will go back to where the presenter is,
and you can move really forward, sorry, backward.
So, right now, we are also, there is a patch,
which is yet to be murdered,
that you cannot move forward than the presenter.
Just in case, let's say,
teacher is doing a quiz,
and the next slide is answer,
that would be very unfair to all the students who goes forward.
So, in that case, case,
we don't allow followers to go forward,
but only the backwards.
And credit goes to K-lon,
and Pedro, for all the design,
if you see anything beautiful,
it's Pedro.
If you see anything ugly, Pedro hasn't seen it yet,
ping him.
And that's it, thank you.
Any questions?
Sure.
Yes?
So, you have made two, when are you shooting?
Uh-huh.
Because when you look at it,
I am the only one that gets into the room between the slides.
So, it's not a joke.
So, you discuss different screen resolutions.
Mm-hmm.
How about accessibility?
How, um, and next year?
So, if the accessibility is enabled on your side,
on your system,
you'll be able to have all the accessibility feature,
because the slide show,
which you have joined,
is running natively on your system,
as if you are running the presentation.
And just before this feature was introduced,
we also enabled accessibility for the presentation
and the slide show.
So, that should not be a problem.
I would be interested in the view.
I don't have accessibility enabled in this system,
but-
It's a default,
let me show you.
Sorry.
I am sorry.
But there is a presentation,
but just-
It's available on callable online.
So, it's a default feature in callable online.
You can-
It's calledable online.
It's calledable as a platform.
Yes.
Are you shooting?
Yes.
We are working very hard on accessibility features right now.
Some servers run by different people,
may have accessibility disabled on the backend,
because of performance issue,
but that's with the admin,
with that instance.
But callable supports it.
It depends upon the provider of the service
if they have enabled or not.
I don't have accessibility enabled on my system.
Unfortunately, right now.
Next question.
You can make edits to the slides,
while somebody else is presenting them.
Others edits visible in the presentation.
Next question.
You can make edits to the slides,
while somebody else is presenting them.
Others edits visible in the presentation.
No.
So, if you have started the presentation,
the slides are already rendered.
So, your edit will not be visible in the slideshow.
You have to restart the presentation.
I'm always annoyed by that.
It's very difficult.
Any questions?
Then that's it.
Thank you.
