Eye contact
The eyes are a very important presentation aid when used properly. They provide a direct link between the presenter and the audience. How you handle that connection can make a significant difference to the outcome of the presentation.
If you avoid looking at the audience - concentrating instead perhaps on the screen, your notes or your shoes - you'll give the impression that you don't care about them. They'll think you're arrogant and cold. The actual reason may be because you're nervous or shy but they won't know that.
If you want to get your message through to the audience - and get a sympathetic reception - you have to make eye contact. First, let see how it should be done.
Eye Contact - Small Groups
Start at one side of the room. Look into the eyes of a person for two to three seconds - as you make a point - and then move on to the next person. Rather than looking at each person in strict rotation you can move across the room and connect with a person there and then move back. However, make sure you connect with everyone in the room - not just those that seem to agree with you (or the attractive ones!).
Eye Contact - Large Groups
If it's not possible to connect with each person individually then divide up the audience into sections and pick a person in each section. Repeat the method outlined above - but never connect with the same person twice. When you return to the same section pick someone else.
Eye Contact - Faking it
If you find it difficult to make proper eye contact with anybody there is a still something you can do. Instead of looking directly into the person's eyes look at the top of their forehead. This will give the impression that you are looking directly at them. After a while - when you are comfortable with this - move your gaze to the bridge of their nose - right between their eyes. After some time doing that you may eventually be able to look each member of your audience directly in the eye.
