Explore About The Document Cameras

Document cameras are visual teaching aids for presenting an object to a large group of students. Document cameras are high resolution video cameras mounted on the arms to do visual presentations in the classroom increasing the efficiency of the lessons. The student can watch their teacher writing on a sheet of a paper or displaying a two or three dimension object onto the projection screen or the interactive whiteboard with the Document cameras. Document cameras have a number of connections to the projector, interactive whiteboard, computer and television. Document cameras can capture images of the documents, 2D or 3D objects and any thing in the real time. The zoom feature of the document cameras allows the students to view the flower components, mould and rocks in minute details. The 2D, 3D objects and other scientific samples can be visually explored as a whole class by the document cameras. Since the document cameras are able to capture the things, there is no need for photocopying. The captured images can be recalled later and can be shared on the network of computers as a resource for learning and teaching. Document cameras can also be used to create 2D or 3D animations. Some Educators integrate interactive response system with the document cameras in their presentations. They can create a question slides embedded with video of science procedure and a teacher asks the student questions about the procedure. Document cameras are now the most wanted ICT based teaching tool apart from Interactive Whiteboards in schools, colleges and the universities.
