Interactive Projectors are a powerful collaboration tool that allows users to interact and control their choice of content while also marking up documents by touching directly on the surface. Those saved annotations can then be saved and distributed for later use. Some models, like the Epson BrightLink series projectors, provide additional benefits with a design for short throw applications and no need for an electronic whiteboard surface. This means you can project and interact on virtually any smooth, flat surface or existing white board.
It is fantastic either in a boardroom or in a classroom.
