What are objects that the audience can see, touch, smell, or hear during a presentation called?

In the context of a presentation, objects that the audience can see, touch, smell, or hear are referred to as props. Props are essential in enhancing the audience's understanding and engagement with the presentation as they provide concrete, tangible relationships to the subject matter being discussed. They can serve to illustrate points, demonstrate concepts, or evoke emotions in a way that words alone might not achieve.

The use of props can significantly enrich the audience's experience by making the information more relatable and memorable. For instance, in a fire and life safety presentation, demonstrating a fire extinguisher or showing visual aids related to safety measures effectively ensures that the audience can visualize and understand critical safety concepts.

In comparison to other choices, tools are generally instruments or devices used to accomplish a particular task but do not specifically refer to objects designed for presentation. Instruments might suggest more scientific or technical objects, which may not encompass the broader array of presentation aids. Materials typically refer to the substance or content from which props may be made, but they lack the interactive or illustrative quality associated with props in a presentation setting. Thus, props are the most fitting term for these objects used to enhance communication and engagement during presentations.
