Talk to the people, not at them.
Watch the eyes!
Whether it is one person or a room full of people, talk to their eyes. Spend your time “visiting” with the audience. Look at different people just as you would in a conversation with a group of friends. Talk to everyone in the room including your fellow presenters.
Remember you are communicating. You can’t do that if you are not focused on the audience. Look the audience in the eye to get the feedback you need.
Never turn your back on the audience. Don’t make the mistake of constantly looking at the screen or other visual aids instead of looking at the audience. It is rude, distracting and very confusing. If you must point something out, place your hand on the spot and turn back to the audience. Next time you are watching the TV news, observe how the weather person from your local TV station does it. They talk to you, not the map on the wall behind them.
