～プロジェクターの歴史と今～ The first idea of projecting an image on a surface was envisioned in a drawing by Johannes de Fontana in 1420. It was a sketch of a monk holding a lantern. The magic lantern of those days looked like a kerosene-fired slide projector. The lantern slides were large, bulky, complex objects, made of glass, paint, wood and metal. In the mid 1990s, with scientists and engineers working hard, a new technology was created that eventually led to the first multimedia projector. So the need was for a multimedia ultra portable wireless projector with a user-friendly design that would allow users to easily present any combination of computer graphics, audio and/or video, to business meetings, sales presentations, training sessions or software demonstrations. With so many technological advancements in multimedia projectors, you’d think that somewhere, there’d have to be a limit. Well, right now, there’s no end in sight, at least not in the near future. Look what’s coming next! As the wireless age creeps in, projectors won’t have those bulky VGA cables connecting the projector to your laptop. And, with the onset of PDAs, you’ll soon be able to manage your entire presentation in the palm of your hand. ＊ Source: http://www.thehistoryof.net/history-of-projectors.html
