Visual Aid or Visual Attack?

Which of these do you do when your desk is a mess and you can’t deal with everything on it anymore? Freeze? Leave? I bet you ultimately re-arrange things into more manageable piles. Why? Because your brain becomes frazzled and momentarily short circuits.  It cannot absorb so many seemingly equally important stimuli demanding your attention, so it re-groups to where it can manage what it sees.   That same short circuiting happens when you present overloaded visuals in a presentation.  You short-circuit your listener’s brain and your listener  tunes  out.  To avoid that short-circuiting, keep these five points in mind when creating presentation visuals.
