1011

There are a variety of ways, both high-tech and low-tech, to present aids effectively.

Computer-generated displays like digital projectors and LCD (liquid crystal display) panels allow speakers to project visual or multimedia information from a computer or an online source onto a screen. Computer-generated displays can also work in tandem with software like PowerPoint, making it easy to create dynamic multimedia presentations and generate notes and audience handouts that correspond to your speech.

Overhead transparencies are images on a transparent acetate sheet viewable via projection. Transparencies are most useful in demonstrating real-time annotation of visual data—for example, a speech in which mathematical equations must be solved or explained for the audience. When using overhead transparencies:

Flip charts are large paper pads on which a speaker can write or draw visual aids. Flip charts are usually prepared in advance and then flipped through during the speech as necessary—however, speakers can also write and draw on the paper as they speak.

Posters are large paper boards on which the speaker places text, data, and/or pictures. Posters can introduce main points or show main points in detail. The benefit of posters is that they are inexpensive and disposable, and if designed well, they can add immeasurably to both your presentation’s clarity and your speaker credibility.
