What is the interactive document camera?


    Document cameras, which is also called visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices for displaying an object to audience. Document cameras can magnify and project actual three-dimensional objects. Essentially, they are high-resolution webcams that are mounted on the mechanical Arm for placing above the objects. It supports teachers, lecturers or presenters a way to display two or three-dimensional objects while the audience watches. Through a document camera, all objects can be displayed theoretically. Most objects are just placed under the camera. The camera takes a picture and then uses a projector or monitor to present a real-time image. Different types of document cameras have great flexibility in object placement. For example, you can simply place larger objects in front of the camera and rotate the camera as needed, or you can use a ceiling-mounted document camera to capture larger range.

    Document cameras are often used in lecture halls or classrooms. In the classroom, teachers can present paper materials such as examination papers, knowledge outlines, etc. Providing evidence in court and some medical presentations such as telemedicine, telepathology, X-ray display, etc. can also be achieved through document camera. 

    With the help of the zoom function, the document camera can enlarge the small fonts in the book and project the printed pages, just like traditional transparencies. Similarly, the room lighting can be operated without dimming the document camera. In the classroom, it is an helpful tool for teacher to give a class better. Most document cameras can also send video signals to a computer via a USB cable. Sometimes, the document camera is connected to IQBoard interactive whiteboard or IQTouch interactive flat panel instead of a standard screen.
