How to keep eye contact with the audience

Since we often have to speak at meetings and conferences, we have developed a technique for keeping the attention of the audience and engaging listeners in the process. When there are less than 50 people in the room, you can maintain eye contact with each of them. When there are more people, you have to stay farther from them. And here a different approach is needed. Choose real or imaginary points in the corners of the audience and another in the center. Direct the look at them. If you stand at a distance of 10 meters from the first row, then about 20 people from the group will feel that you are looking at them, and you will be able to connect with most of the audience.
