Douglas Engelbart's NLS demonstration combined hypertext, collaborative editing, a mouse, multiple views and remote video into a working system for augmenting collective intellectual work.
The computer mouse emerged from Douglas Engelbart's augmentation research, was engineered by Bill English at SRI, and evolved at Xerox PARC before becoming a defining input device for graphical personal computers.
Alan Kay's Dynabook was not merely a prediction of the tablet. It was a proposal for a portable, programmable personal medium that children and adults could use to think, learn, create and communicate.
The Xerox Alto combined a bitmap display, mouse, Ethernet and interactive software into a personal networked workstation that became a laboratory for modern graphical computing.
Xerox Star transformed PARC research into a commercial office system whose icons, folders, document-centered desktop and consistent generic commands were designed through an unusually systematic HCI process.
Apple Lisa brought a mouse-driven graphical desktop into the personal-computer market while its designers repeatedly tested and revised icons, documents, menus and desktop behavior.
Bill Atkinson's HyperCard let Macintosh users combine cards, buttons, text, graphics, links and scripts into interactive stacks, collapsing the distance between using software and making it.
The iPhone's 2007 multi-touch interface made fingers, gestures and sensors the default control system for a mass-market pocket computer, reshaping expectations for mobile software.
Sketchpad let a user draw, constrain, copy and manipulate geometric objects directly on a computer display, demonstrating a new form of conversation between human and machine.
Vannevar Bush's 1945 Memex proposal imagined a personal information machine built around associative trails rather than rigid indexes, anticipating central ideas in hypertext and knowledge navigation.
