Hi, I'm Cal, thank you for watching. Did you know that only visual aids sometimes really is an audio visual obstacle, that means that is really damaging and hurting your presentation and up supporting you. A lot of people I've seen doing presentation is to hooked up on the presentation itself. So they think that the PowerPoint presentation is going to deliver the whole presentation for them. That's not the case, you're the one that are doing the presentation. Please think that a PowerPoint presentation is really a competitor to your message.

People can't pay attention to the PowerPoint presentation at you at the same time. So you're the one delivering the message. When and if you choose to use the PowerPoint presentation, please be aware of the old phrase that 1000 words will be replaced by one picture. So that means if you could use graphical illustration, and be careful on how to use the PowerPoint slide, you will not be competing with the old message. So think about that audio visual obstacle could be the case then audio visual aids.
