Visual aids

  1. 1. Visual aids
  2. 2. Using visual aids is a good way to make your speech clearer, effective, and memorable. Overhead projector, slides, and LCD are common technology for the visual aids. They are used for the charts ,a graphs and illustrations, diagrams and drawings in presenting your data to support your point. Using visual aids during the speech
  3. 3. Charts are used in presenting relationship, while graphs are for comparison illustrations, diagrams, and drawings are used to make image to your exposition, process , and description. It is true that picture paints a thousand words. Charts
  4. 4. If you decide to use slides or overheads projectors, make sure you’re familiar with the equipment involved and the lighting system of the room you’ll be working in. Leave enough time before your presentation to prepare your visual aids adequately. If you don’t have much time, flip charts are good choice.
  5. 5. 1. Put an appropriate amount of information and data on each chart or graph. Too much data can overwhelm the audience and be difficult to remember. 2. Triple-check all numerical values. A slight error in just one number can discredit your entire presentation. How to use Charts, Graphs, and Diagrams
  6. 6. 3. Make pie chart slices match their percentage values. A slice indicating 10 percentage should account for 10 percent of the total pie. Make sure slices are accurate by multiplying their percentage values by 360(10 percent of 360 is 36) and measuring an appropriate angle with a protractor (36 degree in our example).
  7. 7. Pie Chart
  8. 8. 4. Keep your bar graphs in two dimensions. Three-Dimensional bar graphs are difficult to read accurately. 5. Add graphics to your charts graphs, but be discriminating. If there are too many or they’re too large, they will distract your audience. 6. Print large, fat letters and numbers on your charts so that the data will be visible from the back of the room.
  9. 9. 7. Write in the top two-thirds of each charts sheet. 8. Use dark colors (Black, and blue work best). Avoid using lighter colors such as yellow, orange, and pink. 9. Consider a variety of darker colors to make your charts, especially when it comes to human figures.
  10. 10. 11. Test your charts’ effectiveness by tying to read them from the far away. If you can’t rad them start again using larger figures. 12. Don’t write too much text on a single page.
  11. 11. 1. Darken the room slightly so your slides will be properly visible. 2. Leave each slide up for at least 20 seconds. 3. If you need to discuss something else between two slides, insert a blank (black) slide between the two slides so that your audience won’t be distracted. Using slides and Overheads
  12. 12. 4. Used software templates to create professional-looking overheads. 5. Number your overheads in case you accidentally drop them. 6. Apply masking tape to the edges of the projector not covered by the overhead to avoid glare.
  13. 13. 7. Use fewer overheads by showing only one part of a single overhead at a time. 8. Stand next to screen (not the projector)after you place each overhead on the projector. This way, your audience doesn’t have to look back and fourth between you and the screen.
  14. 14. 9. Overheads have an advantage over slides in that their order of presentation is flexible. The disadvantage is that they don’t work well for larger audience. 10. Use an overhead projector with two bulbs to allow for quick and easy bulb replacement. Bring extension cord and adapter with you if using an overhead projector. 11. Your presentation shouldn’t rely too heavily on visual aid. They should support, not comprise, your presentation.
