founded the Architecture Machine Group at MIT. Researchers in the group invented new concepts and developed new approaches to human-computer interaction. Inspired, in part, by Ivan Sutherland’s Sketchpad design interface, The Architecture Machine Group’s original focus was to create an architecture machine to help users design buildings without architects. Computer aided design programs, such as AutoCAD, that became widely utilized in the 1980s were influenced by the early work of Negroponte’s Architecture
