There are two general terms for translating a meeting discussion into visuals in real-time:
Graphic recording – the meeting is captured by a graphic recorder, who is dedicated to listening, synthesizing, and organizing the content into visuals and text.
Graphic facilitation – the meeting is facilitated by one person who simultaneously uses graphics to help guide the discussion and organize action items. Often pre-designed charts are used – these large scale templates help focus the group.
I operate as a hybrid of the two – graphic recording the discussion, and closely involved in planning the graphic templates that will help guide the discussion.
