In our last lesson, we got introduced visual aids, why we
should use them and different types.
Let's proceed
General Design Principles for Visual-aid
presentations
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
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
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
Pie charts are
good for illustrating percentage relationships or parts of a whole. No more
than eight segments are recommended.
Line Graphs
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.
Photographs
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.
