Final answer:
The use of eye contact in communication is known as oculesics, which is part of nonverbal communication strategies to engage and connect with an audience.
Step-by-step explanation:
The use of eye contact in communicative settings is referred to as oculesics. This aspect of communication is a subset of nonverbal communication that involves making and maintaining eye contact to build community, express comfort, and establish credibility. Making effective eye contact is often a strategy used to keep an audience engaged during presentations and speeches. Unlike proxemics, which concerns interpersonal space, or kinesics, which deals with body movements and gestures, oculesics specifically focuses on how eye behavior can convey different messages.
