What role does body language play in making oral presentation effective

When you are presenting in front of an audience, you are performing as an actor is on stage. How you are being perceived is very important. Dress appropriately for the occasion. Be solemn if your topic is serious. Present the desired image to your audience. Look pleasant, enthusiastic, confident, proud, but not arrogant. Remain calm. Appear relaxed, even if you feel nervous. Speak slowly, enunciate clearly, and show appropriate emotion and feeling relating to your topic. Establish rapport with your audience. Speak to the person farthest away from you to ensure your voice is loud enough to project to the back of the room. Vary the tone of your voice and dramatize if necessary. If a microphone is available, adjust and adapt your voice accordingly.

Body language is important. Standing, walking or moving about with appropriate hand gesture or facial expression is preferred to sitting down or standing still with head down and reading from a prepared speech. Use audio-visual aids or props for enhancement if appropriate and necessary. Master the use of presentation software such as PowerPoint well before your presentation. Do not over-dazzle your audience with excessive use of animation, sound clips, or gaudy colors which are inappropriate for your topic. Do not torture your audience by putting a lengthy document in tiny print on an overhead and reading it out to them.

Speak with conviction as if you really believe in what you are saying. Persuade your audience effectively. The material you present orally should have the same ingredients as that which are required for a written research paper, i.e. a logical progression from INTRODUCTION (Thesis statement) to BODY (strong supporting arguments, accurate and up-to-date information) to CONCLUSION (re-state thesis, summary, and logical conclusion).

Do not read from notes for any extended length of time although it is quite acceptable to glance at your notes infrequently. Speak loudly and clearly. Sound confident. Do not mumble. If you made an error, correct it, and continue. No need to make excuses or apologize profusely.

Maintain sincere eye contact with your audience. Use the 3-second method, e.g. look straight into the eyes of a person in the audience for 3 seconds at a time. Have direct eye contact with a number of people in the audience, and every now and then glance at the whole audience while speaking. Use your eye contact to make everyone in your audience feel involved.

Speak to your audience, listen to their questions, respond to their reactions, adjust and adapt. If what you have prepared is obviously not getting across to your audience, change your strategy mid-stream if you are well prepared to do so. Remember that communication is the key to a successful presentation. If you are short of time, know what can be safely left out. If you have extra time, know what could be effectively added. Always be prepared for the unexpected.

Pause. Allow yourself and your audience a little time to reflect and think. Don't race through your presentation and leave your audience, as well as yourself, feeling out of breath.
