The Japanese electronics and Optics manufacturer, Elmo, is the organization behind the Elmo projector. The device combines the projection system and the document camera to display documents and other objects that are not translucent to a group of people, such as in a lecture room.The Elmo cameras in the projectors can capture not only documents but also 3D objects. However, these objects will be rendered in 2D format. You can also use the Elmo projector to watch a movie. However, that is not the most appropriate use of the device. But it is always good to have more options.
