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.

A study comparing the speed, accuracy, and user satisfaction of three different touch screen strategies was performed. The purpose of the experiment was to evaluate the merits of the more intricate touch strategies that are possible on touch screens that return a continuous stream of touch data. The results showed that a touch strategy providing continuous feedback until a selection was confirmed had fewer errors than other touch strategies. The implications of the results for touch screens containing small, densely-packed targets were discussed.

Several striking and surprising characteristics of how people use interactive systems are abstracted from a large body of recorded usage data. In particular, we examine frequencies of invocation of commands and complete command lines (including modifiers and arguments), as well as vocabulary growth. Individual differences are of particular interest, and the results are analyzed by user and by identifying groups of like users. The study underlines the remarkable diversity that exists even within groups having apparently similar needs.
Currently, the main problem with automated target recognizers (ATRs) is not a low hit rate but rather a high false alarm rate. The use of multiple sensors has frequently been proposed as a means of reducing this false...

System design should be controlled by sound engineering principles. We discuss issues concerned with the derivation and formalisation of such principles that may be employed in the construction of specifications of in...

An experiment was conducted to compare online computer manuals to paper manuals. For each type of manual there were two different database structures – a linear (sequential) structure and a tree structure. The results showed that people using the paper manuals were faster at performing a switch setting task based on information in the manual than were people using the online manuals. No significant differences were found in speed of performance between the linear and tree structures. Nor were there any differences in the number of correct switch settings for the different types of manuals. The subjective evaluation data revealed that the online manuals were rated as better and judged to be more organized than the paper manuals.
