Eye contact is a nonverbal technique that helps the speaker "sell" his or her ideas to an audience. Besides its persuasive powers, eye contact helps hold listener interest. A successful speaker must maintain eye contact with an audience. To have good rapport with listeners, a speaker should maintain direct eye contact for at least 75 percent of the time. Some speakers focus exclusively on their notes. Others gaze over the heads of their listeners. Both are likely to lose audience’s interest and esteem. People who maintain eye contact while speaking, whether from a podium or from across the table, are "regarded not only as exceptionally well-disposed by their target but also as much more believable and earnest."
    To show the potency of eye contact in daily life, we have only to consider how passers-by behave when their glances happen to meet on the street. At one extreme are those people who feel obliged to smile when they make eye contact. At the other extreme are those who feel awkward and immediately look away. To make eye contact, it seems to make a certain link with someone.
