- A change in the pace of your speech helps emphasize your points.
- Moving around physically helps connect you with your audience.
- Letting loose with a variety of facial expressions makes you more human.
As an example, see the photos below of Jim as he presents an idea to a local TED audience. His passion practically jumps off the screen at you. His expressive physical gestures might seem overstated to you seeing them here. However, he was addressing an audience of hundreds in a large hall, and Jim’s gestures properly expanded to meet your environment.
