All Human-Centered Computing

Pioneers whose defining contribution is how people operate and engage with computer systems, the field the ACM Computing Classification System names Human-Centered Computing (this atlas's prior pioneer field of the same subject was titled Human Computer Interaction; the people and the subject are unchanged). Douglas Engelbart's invention of the computer mouse and founding of the field, Andries van Dam's early hypertext systems, Ben Shneiderman's direct manipulation interfaces, Larry Tesler's interface work at Xerox PARC and Apple, Randy Pausch's interface research and Wendy Hall's hypermedia work. Does not belong here: a pioneer whose defining work is the graphics rendering behind an interface rather than the interaction design itself, filed under Computing Methodologies instead.
