Part 1
When showing the comparison between two concepts within a particular period to an audience, they are likely to forget if there are no visuals of the data. Assume for instance describing how the keyboard of a computer is used without a picture, in such an occurrence the audience will not correctly understand as there are no means of reinforcing the key points.
Part 2
It is a wise to decide when addressing an audience to present information by constructing data to visualize the data. To be able to achieve this the use of graphs, pie chart, diagrams, and pictures among others can be applied. They are useful in explaining trends, indicating portions of a whole and comparing. They also help the listeners in visually completing their understanding of the procedure being explained to them.
A poster can reinforce key topics of speech, support the steps of a procedure and explain unfamiliar concepts. Additionally contrary to prepared posters, a chalkboard gives the speaker lots of flexibility during the presentation. This is because unknown vocabularies can quickly be noted down or a simple explanatory sketch can be drawn.
Part 3
It is surprising how most speakers become too involved with the visual aids to the point where they forget to look at the audience. It can be seen that this is usually brought forth by inadequate practice for the presentation. It is also helpful as a speaker to always set the visual aids before the presentation so as to avoid unnecessary disruptions and save on time. However, it might be confusing for a speaker to know how big his or her images should be when preparing for the presentation. This is because this will all depend on the audience taste and preference.
