eZuce Vibe's new Lightboard Feature

We were exploring some of the Lightboard setups that some universities have been working on (https://lightboard.info/). We had started messing with OBS (Open Broadcast System) a while ago and we were able to stream that content into the Vibe client. However, we ran into some performance issues (delay) with this setup. Frankly, it was also pretty complex to setup and make work. Too much to ask of a typical user...

Our Vibe Collaboration Client comes from a product developed at CalTech for distributed research teams. The client has some pretty powerful video capabilities (multiple camera inputs on each PC, all users can desktop share at the same time, hundreds of people in meetings, etc.). 

So, instead of trying to work with OBS we figured out a way to use the desktop sharing component and create a transparent image by using a key color (i.e. like a green screen):

The following slide in PowerPoint was setup with with the pink color as the background (this will of course work with any application that will let you control the background color):

All the user needs to do now is enable the Lightboard option in Deskshare.

When the user is ready to run the Lightboard its as easy as turning on Deskshare. 

Deskshare maps out the key color and overlays the remainder of the slide on whichever camera input you'd like (sorry for the ugly mug):

We also flip the local video for the user to make it easy for them to interact with the slide.

If the user has a tablet PC or pen input device it's easy in PowerPoint to draw live on slides. Then you have nothing to erase like with a traditional piece of glass lightboard.

In the following example I simply made my Mac's desktop the same as the key color and shared the entire desktop. (the Vibe software runs on Mac, Windows & Linux btw...)

There you have it...  No expensive Lightboard rooms to setup (or to try to drag users to), Live presentations (no post processing required), use with any application, and Super easy to use! 

Users can also record directly into MP4 and do some post editing / etc.  It's up to the user if they want to do it live or not.

We're in Alpha testing with this now, beta in July and we're expecting it to hit production at the beginning of September 2019. Let us know if you'd like to get on the Beta list or if you want a live demo! 

If you already have research teams using Vibe they'll just get this new feature when their client updates!
