document camera
Page display device
A document camera is a device that captures and displays real-time images of physical objects, documents, or demonstrations onto a screen or monitor.
It functions like an overhead projector but uses a digital camera instead of transparencies: The teacher placed the worksheet under the document camera so everyone could see.
Common in classrooms and presentations for showing books, student work, or hands-on activities to a group.
