A Visualizer is the most flexible presentation tool of our times. It can pick-up any kind of material (books, photos, 3-dimensional objects etc.) quickly and easily and provides a high resolution output signal for video/data projectors, monitors, interactive whiteboards or videoconferencing systems. 

Compared to rather “stiff” Power Point presentations, a presentation with a Visualizer is much more flexible and “alive” because anything can be displayed at any time, with no fixed order and without any advance preparation.

Real-time, live presentation: You can point, write, mark, zoom in and out and get different views and angles on an object. It is a true live-interaction tool.
