The term visual aid is self-explanatory. Visual aids help to enhance the involvement of the audience and increase their interest in the presentation.
Step-by-step explanation:
Various types of visual aids can be used to increase the efficiency of a presentation. Before a presentation starts, handouts should be distributed that contains information about the key points covered in the presentation.
The presentation can be made more engaging by adding more relevant images and even videos.
A whiteboard should be used to convey information about the presentation. If the presentation is about some product, then some samples and props should also be used and giving a demo trial will always be a plus.
