Document Camera
A document camera is a hardware device that captures real-time images or video of documents, objects, or 3D items, projecting them onto a screen or display for viewing. It functions as a modern overhead projector, often used in educational, business, and presentation settings to share physical materials digitally. These devices typically connect to computers, projectors, or interactive whiteboards via USB, HDMI, or wireless connections.
Developers should learn to use document cameras when creating educational software, remote collaboration tools, or applications requiring real-time object scanning, as they enable seamless integration of physical artifacts into digital workflows. They are particularly useful in e-learning platforms, virtual classrooms, and tech demos where visual aids enhance communication, such as in coding tutorials that involve hardware components or paper-based diagrams.
