The integrated software and user interface of Apple's Lisa
Edward W. Birss · AFIPS conference proceedings · 1984
In 1979 Apple began to develop Lisa, a workstation to enhance the productivity of office workers. The hardware was built around a Motorola 68000, a bit-mapped display, and a mouse. The user interface is intuitive, using real-world concepts rather than computer concepts. It is easy to learn, and provides for both novice users still learning the system and users that have mastered the system. The user interface is modeless and consistent. The uniformity of the user interface supports transferable learning---the ability to learn an operation once and apply it over and over again in another application in a different context.
