Abstract
This document comments on the upsurge in interest in providing better
ways for people to interact with information processing systems. After
pointing out that the programmer is also a user, it sets down structured
principles and rules for designing better human-computr interfaces, with
an indication of the considerations on which each rule is based. Two
supporting documents are associated with this one. An informal discussion
of some of the issues and steps involved in designing human-computer
interfaces appears in Dialogue design notes (D.R. Hill 1984), and
there is also A bibliography on human-computer interaction
(D.R. Hill 1984), to which references refer.
