The fourth goal of body language is to engage the emotions of your audience and make them feel connected to you and your information. To do this, you need to use facial expressions, gestures, and stories that express, invite, or evoke emotions. For example, you can use your facial expressions to show that you are happy, sad, angry, or surprised by your information or by the reactions of your audience. You can also use gestures, such as pointing, clapping, or thumbs up, to show that you are inviting them to participate, agree, or celebrate with you. You can also use stories, such as anecdotes, examples, or testimonials, to show that you are relating to them, inspiring them, or challenging them. Avoid hiding your emotions, being too formal, or being too emotional, as this can make you seem insincere, distant, or unstable.
Body language is a skill that you can learn and improve with practice and feedback. By using body language to capture attention, simplify concepts, emphasize points, and engage emotions, you can convey technical information clearly and concisely and become a more effective and persuasive communicator.
