Real-time image capture devices for displaying an object to a large audience are USB document cameras, also known as visual presenters, visualizers, digital overheads, or docucams.
A document camera is essentially a high-resolution web cam that is mounted on arms to make it easier to place them over a page.
It is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies, just like an opaque projector.
[1] A teacher, lecturer, or presenter can use this to write on a sheet of paper or show a two- or three-dimensional object to the audience while they are watching.
A document camera can theoretically display all objects. The majority of objects can be easily hidden from view. The picture is taken by the camera, which then uses a projector or monitor to create a live image.
The various kinds of document cameras and visualizers make it very easy to move objects around. A ceiling-mounted document camera can also be used to make use of a larger working space by simply putting larger objects in front of the camera and rotating it as needed.
A document camera can be very useful for interactive online teaching, developing materials, or in-person teaching.
A camera set up to show a page as the teacher writes on it can be a good alternative to the old overhead projector or blackboard in the classroom.
The teacher’s writing can be seen by the students. Because many document cameras use video outputs that are difficult to connect to a computer, they are useless for online teaching with computer-only systems like Skype, Zoom, and Webex.
The Title Name accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
