“…As a result, these tools are generally not documented and not made available for use outside of the organization. The case studies of usability efforts in commercial organizations (for examples, see [Hertzum, 1999, Szczur, 1994) discuss the processes used to perform usability testing and the resulting impact but not the tools used to support the processes. One exception is a panel discussion about in-house usability tools that included representatives from several major companies as panel members [Weiler, 1993].…”

The usability of an application often plays an important role in determining its success. Accordingly, organizations that develop software have realized the need to integrate usability engineering into their development lifecycles. Although usability practitioners have successfully applied usability engineering processes to increase the usability of user-interaction designs, the literature suggests that usability practitioners experience a number of difficulties that negatively impact their effectiveness. These difficulties include identifying and recording critical usability data, understanding and relating usability data, and communicating usability information. These difficulties are particularly pronounced for novice usability practitioners. v Table of Contents 1 Introduction.

“…These variations and pauses indicate a lack of control when compared to an idealised 'perfect' cursor movement. Tasks were initially given a quality rating of 5 (perfect) [20], with subsequent errors reducing the quality until the task was completed or failed, and the next task started. To reflect the consequences of generating each error type, the quality factors were weighted, giving a simple formula for quality ( Figure 1).…”

This paper quantifies the benefits and usability problems associated with eye-based pointing direct interaction on a standard graphical user interface. It shows where and how, with the addition of a second supporting modality, the typically poor performance and subjective assessment of eye-based pointing devices can be improved to match the performance of other assistive technology devices. It shows that target size is the overriding factor affecting device performance and that when target sizes are artificially increased by 'zooming in' on the interface under the control of a supporting modality then eye-based pointing becomes a viable and usable interaction methodology for people with high-level motor disabilities.manipulation of the interface. The aim of this paper is to investigate the performance of direct manipulation using an eye mouse on a standard graphical user interface and to show how the performance of an eye mouse can be dramatically improved by the addition of a 'zoom screen' facility.

Many research projects in public-participation geographic information systems focused on the development of software prototypes that were conceptualized to complement traditional forms of public participation. Given the challenges introduced by the heterogeneity of their user base, system design, and decision making process, empirical evaluations of such systems based on actual use have been scarce. This article reports on a rigorous empirical assessment of human-computer interaction of users of a web-based system for participatory transportation planning. We devised three groups of participants with belowaverage, average, and above-average interaction duration through hierarchical cluster analysis. Subsequently, the characteristics of the clusters were subjected to logistic regression analysis to determine the significance and strength of statistical associations between duration of interaction and a host of individual-level variables. Our results indicate a statistically significant reduction of the odds-ratio for participants with above-average duration of interaction in the case of no prior experience with online transportation discussions. No significant associations were found between overall duration of interaction and sociodemographic background, cognitive decision-making style, and travel behavior. We advocate for the development of adaptable participatory systems which accommodate flexibility in terms of both the user interface and pathways of the decision making process.
