Visual aids

Of all the information that enters our brains, the vast majority of it enters through the eyes. 80% of what your audience learn during your presentation is learned visually (what they see) and only 20% is learned aurally (what they hear). The significance of this is obvious:

• visual aids are an extremely effective means of communication
• non-native English speakers need not worry so much about spoken English - they can rely more heavily on visual aids

It is well worth spending time in the creation of good visual aids. But it is equally important not to overload your audience's brains. Keep the information on each visual aid to a minimum - and give your audience time to look at and absorb this information. Remember, your audience have never seen these visual aids before. They need time to study and to understand them. Without understanding there is no communication.

Apart from photographs and drawings, some of the most useful visual aids are charts and graphs, like the 3-dimensional ones shown here:

Piecharts are circular in shape (like a pie).

Barcharts can be vertical (as here) or horizontal.

Graphs can rise and fall.
