A document camera improves projector visibility during presentations.
If you have ever listened to a presentation in a class or business meeting, you may have seen the presenter use a document camera. It's a piece of equipment that displays objects that are placed under its lens onto a large projector screen. This type of camera works well for displaying information, such as training notes, outlines and graphs to a large room of people. Document cameras have several advantages when used in various fields, such as education and business.
Versatility
Document cameras allow you to show all types of media in a classroom or office setting. The media used on this type of camera can be in various formats, such as computer printouts, handwritten material, brochures, photographs or transparencies. The camera also can display various types of objects, as long as they are small enough to fit in the camera's visual area. Because the camera accommodates many types of media, a presenter has more choices of material he can display than with other methods, such as an overhead projector.
Visibility
If you take a college course in a large hall or receive group training in a conference room at work, it may be hard for you to see important notes your professor or boss needs to cover. Document cameras improve your visibility by enlarging media so that everyone in a room can view it. Color printouts, book pages, three-dimensional objects and photos are all types of media that a document camera can project into larger displays on screen.
Time
Any document or item that fits inside of an 8 1/2-by-11-inch area can be placed under the lens of a document camera. This eliminates having to photocopy documents or transfer them to transparencies for use with an overhead projector. It also saves time by eliminating the need to write information on an whiteboard or chalkboard.
Engagement
When a teacher or presenter uses a chalkboard or whiteboard to write notes for a presentation, he loses a connection with his audience because his back is turned on them most of the time. Using a document camera helps the presenter keep eye contact and establish a connection with the audience. This keeps the audience engaged in the speaker's presentation.
