One of the great things about graphic recording is that it gives people stuff to talk about - and that stuff is your content!
The photo above was taken in the midst of a large conference. Most people were in one of the many sessions then. But no matter how great any conference may be, people often step out of the room for a bit. It could be for a bathroom break, or to take a phone call, or maybe they need to catch up on some work and skip a session completely.
When graphic recording visuals are displayed in common areas, people can't help but look. And when they look, they're engaged again with the content. They talk about it, too, getting those around them engaged along with them.
As this picture shows, graphic recording brought some people together and increased their engagement!
