Which tool would a presenter use to project images and slides for an audience, similar to an overhead projector?

A document camera is specifically designed to project images and slides for an audience, functioning similarly to how an overhead projector operates. It allows presenters to capture and display documents, images, or physical objects in real-time. This technology enhances presentations by making it easier for viewers to see details on materials that can be difficult to share with a traditional projector setup.

In contrast, a smart projector may offer various advanced features, such as connectivity to devices or interactive capabilities, but it generally focuses on projecting content from a connected source rather than solely on displaying documents or slides. A digital whiteboard serves as an interactive platform to write and display information, which, while beneficial for collaboration, may not serve the specific function of simply projecting static images. A video display screen primarily functions as a surface for visual content but requires a signal from another device to display that content, unlike the document camera, which directly showcases the object in front of it.
