Development of an instrument measuring user satisfaction of the human-computer interface

TLDR

The study develops the Questionnaire for User Interface Satisfaction (QUIS) and discusses its future applications on computers. The authors surveyed 150 PC users, having them rate familiar software, comparing liked versus disliked programs and a command‑line system versus a menu‑driven application. The questionnaire showed high reliability (α = 0.94) and revealed that users rated liked software and menu‑driven applications higher than disliked software and command‑line systems, with frequent PC users finding MDA more satisfying, powerful, and flexible.

Abstract

This study is a part of a research effort to develop the Questionnaire for User Interface Satisfaction (QUIS). Participants, 150 PC user group members, rated familiar software products. Two pairs of software categories were compared: 1) software that was liked and disliked, and 2) a standard command line system (CLS) and a menu driven application (MDA). The reliability of the questionnaire was high, Cronbach's alpha=.94. The overall reaction ratings yielded significantly higher ratings for liked software and MDA over disliked software and a CLS, respectively. Frequent and sophisticated PC users rated MDA more satisfying, powerful and flexible than CLS. Future applications of the QUIS on computers are discussed.
