I had been demonstrating the relationship of organization and content to delivery, emphasizing that stories are the currency of human contact, the only way to connect emotionally as well as intellectually. I asked one gentleman to play a game with me. He did so, becoming animated and enthusiastic. Without exception, all the other engineers agreed that he was a much stronger presenter when he talked to them directly and made eye contact instead of just narrating his slides. This proved what I had been telling them all day about the superiority of human contact over electronics.
Technology is terrific - as long as it supports and enhances the connection with the audience.
In the end, a presenter's message depends on creating pictures inside the heads of the audience, not on a screen. Turn numbing data into exciting pictures of what will change in the listener's life. Help them make the decision your briefing is designed to promote. More than any showy visuals, people will remember what they 'see' in their minds while they are listening. Use technology to support the message, not visa versa.
