Visual aids to clarity

Abstract

Visual aids are carrier devices for presenting ideas. They should incorporate the essence of the speaker's thinking-at the planned rate of a single idea each. Principles of accomplishing visual communication are described with emphasis on techniques that involve the speaker: blackboard, flannelboard, easel pad, flip-chart, and transparency and slide projection. Guides for equipment placement and viewing distances are included.
