Presentation Skills

1.The architecture should involve the parts which user are familiar with and other parts which you would like to introduce.
for example, if you want to introduce webcam driver, you should include the total flow diagram from Skype to usb web camera. Introduce each component involved.

For each operation involved, it should include what user does to skype, and what the effect is on webcam driver.

2.The relationship between each slide should be clear. From the brief flow intro to the detail of each function, there should be a clear relationship presented to the audience.

3.Slides design is same as the design of GUI. From Joel( Joel On software) famous book, the audience don't read any text on slides. They just see the picture ( even the lecturer too). It's important to illustrate every idea and even details by drawing.
