In our last lesson, we got introduced visual aids, why we should use them and different types.
General Design Principles for Visual-aid
Visual aids can distract your audience if you do not design them properly. Keep these in mind when creating your visual aid.
1. Use simple or no background in presentation materials
2. Use colors that provide adequate contrast and are readable
3. Use readable font size that allows easy reading of text from the last row of the room
4. Use different font sizes for titles and section headings
5. Limit each point to no more than two, or at most three, lines of text
6. Ensure animations or transitions don't distract
7. Ensure chart scales don't mislead (Use appropriate bars)
8. Show video clips at easily viewable size
9. Do not use offensive or stereotypical visuals
10. Play audio at easily heard levels; test them in advance
11. Proofread and spell-check
Design Principles for Graphs, Charts and Diagrams
Tabular charts are used to show raw data and numerical relationships. Use only a few key examples on the visual to illustrate your point.
Bar graphs are used to show absolute data or relationships and comparisons. Be sure to include scales and values. Be sure the type is legible.
Pie charts are good for illustrating percentage relationships or parts of a whole. No more than eight segments are recommended.
Line graphs are ideal for illustrating trends or performance over time. Your scale should include significant dates and milestones. Graphs should include no more than three lines. In black and white visuals, the lines should be distinctly different, e.g., dashed, solid, dots, etc. In color visuals, the lines should be easily differentiated colors which contrast well with the background.
Block or Process Diagrams
Block or process diagrams are good for illustrating structural relationships and designs. Graphics of this type show how each piece contributes to the whole. Avoid overcrowding. Limit your chart to no more than 10 simple geometric shapes and titles connected by lines and arrows.
Good quality photographic visuals can make a major contribution to your presentation. Be extra careful with photographs: they must be very crisp and clear, with high contrast between light and dark areas. Do not superimpose text over the image. If text is needed on the visual, it should be placed in areas that have been cleared of the image. Be sure to test your photos, projecting them to the size they will be when used to ensure that they are clear and easily recognizable.
