Presenting papers

摘要

Two principles incorporated in visual aids for technical talks can prevent many typical negative audience reactions. The speaker must “put himself into the audience” and be concerned with the legibility and the comprehensibility of the materials he prepares for projection. A simple guide for legibility is that any text within a one-foot frame must be readable without optics from a distance of ten feet. Comprehensibility is guided by limiting each frame to the expression of only one idea.
