5. 4 Direct Manipulation First implemented in the 60’s by Ivan Sutherland in his Sketchpad First implemented in the 60’s by Ivan Sutherland in his Sketchpad Research systems in 1982: Xerox Star Research systems in 1982: Xerox Star Commercialized in 1984: Apple Commercialized in 1984: Apple The notion of WYSIWIG The notion of WYSIWIG Described as a paradigm by Shneiderman in 1982 Described as a paradigm by Shneiderman in 1982

6. 5 Direct Manipulation Properties interface makes the system and its objects visible and provides access interface makes the system and its objects visible and provides access to the user, the interface becomes the system to the user, the interface becomes the system incremental action incremental action continuous, visual and automatic feedback continuous, visual and automatic feedback reversibility reversibility guaranteed syntactic correctness of commands guaranteed syntactic correctness of commands replace language with action replace language with action the blurring of I/O: icons & widgets provide both the blurring of I/O: icons & widgets provide both less flexibility; more usability less flexibility; more usability future: intelligent interface agents future: intelligent interface agents

7. 6 HCI Success Stories Lessons Lessons Most have roots in academic research conducted at universities or corporate research labs Most have roots in academic research conducted at universities or corporate research labs Many advances have fundamentally changed the way we do things – e.g. word processing Many advances have fundamentally changed the way we do things – e.g. word processing The lag from conception to commercial success and to having an impact in our everyday lives is 20-40 years! The lag from conception to commercial success and to having an impact in our everyday lives is 20-40 years!
