This system was designed to be used by teachers and instructors in classrooms or labs. The system will be laser cut and it must be fully in cardboard. It is easy to carry by a teacher in his scoolbag, because all the articulated arm is composed of two joints to fold it.
At the end of my articulated arm, there is a support for the webcam to visualize an A4 document.
Moreover, my school visualizer is very convenient. You will need less than 30 seconds when taken out of the bag to install it and the system is stable on the teacher's desk thanks to the support piece, to compensate the counter weight.
In sum up, this system is eco-friendly, cheap easy to transport and has to look modern and aesthetic.
