Different types of visual aids are used by the speaker/orator in order to make the audience understand with clarity, the information that he/she wants to communicate. The kind of aid used depends on the preference of the communicator, as well as the nature of the subject. Each kind of visual resource has its own set of pros and cons, and hence, it is necessary to choose the one which is most suitable, so that effective communication can be established and the presentation can be made more interactive. The different types of visual help or aids used are as under:
- Actual objects and/or models can be used to make the audience see for themselves, what is being spoken about.
- Info graphics can be used, so that a lot of information can be conveyed through graphical representations. Info graphic tools include maps, tables, charts, and graphs.
- Actual photographs of the subject in question also help to a great extent in establishing effective communication.
- Many times, in the absence of real photographs, diagrams and sketches can also be used for conveying important information.
- Videos are one of the best audio-visual aids, which enable people to actually see how things happen, thus making them understand the subject even more deeply.
Apart from the ones mentioned above, some speakers, depending on the subject, also prefer to make people, not only see but also do certain things. For instance, for a lecture on pottery-making, the listeners may understand the techniques better if they try making pots themselves, rather than looking at others making the same.
