The document camera is a presentation tool which may promote an active and interactive environment.
Document cameras, also known as image presenters, visual presenters, digital overheads, and docucams, are real-time image capture devices for displaying an object to a large audience. Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, in essence, high-resolution web cams, mounted on arms so as to facilitate their placement over a page. This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches. All students have a better view of the information that the presenter is sharing with the class. It must be connected to a video projector or TV.
