Paralanguage
            Paralanguage  includes tone of voice,  loudness, speed of speech,  pausing, and  even silence. This helps you
            understand the context and the meaning of the words used in the communication.
            A cold tone of voice might suggest that you are actually not fine and don't wish to discuss it. A bright and happy
            tone of voice will reveal that you are happy with the things going around in your life. Silence or vocal pauses can
            communicate hesitation, the need to gather thought or serve as a sign of respect.

            Haptics
            Haptics is the power of touch in communication. Each touch conveys emotions and feelings in a physical form with
            a unique message like fear, disgust, love, encouragement, gratitude, sympathy, anger, pain, violence, etc. Studies
            have shown that it plays a very important role in the proper development of babies and in animals it works as a sign
            of love and care. You may begin your interaction with people by shaking hands and making casual conversation.
            This interaction can help establish trust before you start addressing your audience.
            Advantages of Non-Verbal Communication
            Some of the advantages of non-verbal communication are:

               • It is used as complimentary with verbal communication to enhance the effect of communication.
               • Information can  be easily presented in non-verbal communication through  gesture, body  language,  etc.
              A teacher with a finger on the lips conveys not to talk and sit quietly to the whole class. A person addressing
              a crowd uses voice modulation to get the attention of the crowd. Sometimes nodding your head to say yes is
              enough to convey the message.

               • Using gestures, facial expressions, eye contact, touch, etc. can be very helpful for the illiterate and physically
              challenged, especially with hearing and speaking problems.
               • It is useful and easy method of communication where no common language is required to master.
               • It is a fast method of communication as gestures have more impact than words.

            Disadvantages of Non-Verbal Communication
            Some of the disadvantages of non-verbal communication are:
               • Since it uses gestures, facial expressions, eye contact, touch, signs, sound, etc. for communication, there are
              chances of misinterpretation of the message required to be delivered.
               • Different cultures use different ways of non-verbal communication. The difference in message  can lead to
              negativity and offense. For example, people who speak less and are less interactive are considered cold and
              arrogant. However, the Japanese admire silence and consider it as a key to success.
               • Non-verbal communication does not follow any rules or structures, therefore, people unconsciously may engage
              in non-verbal movements which are considered offensive.
               • It is not  suitable for  long and  lengthy  messages  as the  actual  message may get  lost in a lengthy  and
              time-consuming conversation.
               • Sometimes  it is  an incomplete form of communication and needs a support of verbal communication for
              effective and meaningful delivery of a message.
               • Distant communication is not possible using non-verbal communication.

            1.4.3. Visual Communication

            Visual Communication  is the transmission and  interpretation  of information by  using visual resources like
            photographs, videos, art, drawings, sketches, charts and graphs. Visuals enhance the process of communication
            during written or verbal communication for better understanding and a meaningful interpretation of the
            information.
