Which of the following is an example of an interactive display?

An interactive display is characterized by its ability to engage participants actively, allowing them to interact with the content in a way that enhances their experience. In this context, a virtual reality experience stands out as an ideal example of interactivity. It immerses users in a simulated environment where they can manipulate objects, navigate through spaces, and experience scenarios firsthand, fostering deeper engagement and learning.

The other options, while they may provide information or visual appeal, do not offer the same level of participant interaction. A static poster provides visual content but does not allow any form of interaction. A video presentation can be engaging but typically is a passive experience for the viewer, with little opportunity for interaction. A brochure stand offers printed materials for attendees to take away but does not engage them actively in the display itself. Hence, the virtual reality experience is the most fitting example of an interactive display due to its immersive and engaging nature.
