The best possible way to maintain eye contact with your audience, is:
Speak loudly and clearly
Remain calm as possible
DO NOT SAY : UM WHAT SO YEAH YOU KNOW!
Concentrate on your message what you’re putting out there
Start your message strong as possible
Body language is important
When presenting a slide show:
Don’t turn down your screen lights so that the side where your audience is supposed to see you can’t see you
Respond to as many questions as possible when your presentation is finished
Relate to the audience by telling stories
