What are document cameras primarily used for in presentations?

Document cameras are primarily used for displaying physical documents and objects during presentations. This capability allows presenters to project printed materials, such as papers, books, and artwork, onto a screen for an audience to see clearly. The value of document cameras lies in their ability to provide a live display of these items, allowing for interactive elements such as handwriting, annotations, or real-time demonstrations.

While showing transparencies is a function that some older presentation methods might utilize, this is not the primary focus of document cameras, which are more versatile and adapted to modern presentation needs. Options related to digital content display, recording video presentations, and video conferencing highlight other technologies or equipment that serve different purposes and do not accurately capture the unique function of document cameras in a presentation context.
