The message for litigators should be clear. Never read the text on trial exhibits you are displaying for your audience. Instead:
Talk about trial exhibits and legal graphics diagrams.
Pause your oral presentation and ask your fact-finders to read key text silently.
Dim the screen (just press the B key) and read key text yourself or have an expert read the text.
Focus on presenting diagrams instead of text.
Speak words and don't show them.
