Conventionally the index finger has been used to show a specific direction or to indicate an object, but it may also be used to strengthen an allegation or as a challenge by pointing it directly at the audience or even at a single person. The clenched fist is often used by enthusiastic presenters without thought, but almost always is used to portray anger, power or determination. You will see this type of gesture used to back up statements such as "We will never give up!" Both palms raised a little and facing the audience as if asking them to calm down may be used to get them to listen carefully to your next words. As the word implies, descriptive gestures as part of purposeful presentation skills in North West describe or portray an object or an action. For example the enthusiastic presenter may illustrate a small object by holding a thumb and forefinger a few millimetres apart, a large object by holding his arms wide apart, or a tall object by reaching upwards with one arm. Some descriptive gestures may be portrayed by miming, for example portraying the way a person walks, such as limping. A presenter's use of gestures will depend to a large extent on whether his or her personality is vigorous and dynamic or calm and easygoing. Whatever your personality, the effective use of gestures can only add to the success of your presentation. Relax your shoulders, arms and hands and focus on giving your audience the meaning and importance of your ideas - but don't relax on predetermined presentation skills in North West.
