Science+Fiction

Science fiction often takes us into the future and more often than not the authors of sci-fi base future technology on what is available today and how today's technology can be improved. It is not uncommon that many of these ideas come to be. With that said however I do not think that science fiction explains why my obsolete or emerging technology came to be. I think that science fiction would focus on computers where body movements create results instead of simply projecting an image on a board. I can however see where science fiction might dive into the idea of a teacher using virtural reality to instruct or voice commanded responses from the Activboard. The overhead projector came into existance due to a need, not an imagaination. The Activboard did not replace the overhead projector because of an idea in a science fictional film, but because of a true need of today's educators.
