Explain with familiar examples or analogies, and compare your new material with existing technology that is well known to your audience. Follow a Simple Outline - Introduce your problem. Describe your solution. Tell how you did it. Make one point lead to the next.
Comprehension is better when the subject is organized simply.
Use the minimum number of slides that will allow you to convey the essence of your paper to your audience. You have 45 minutes for your presentation. Experience tells us that most SNUG talks do well with between 15 to 20 slides. An outline of your major topics should be your second slide, just after your title slide. Line graphs show trends or correlation effectively.
