Accommodating technology, that is, making it usable in a room, does require many changes: Rooms should be square or rounded instead of rectangular since sight-lines and visual display of information is now as important as the sound of voices; moving furniture for different ways to work with technology should not cause a sudden roar of noise, chair and table legs scraping on tile, but instead the soft rolling of table and chair on a soft surface. In other words, new classroom design is not based on unquestioned tradition but is based on new practices developed within the field of media architecture.
