A structured methodology for comparative evaluation of user interface designs using usability criteria and measures

Previous research in software ergonomics has indicated the importance of evaluating the usability of computer user interfaces. This paper presents a quantitative basis for selecting from among multiple alternative interfaces relative to multiple criteria of usability concern. The proposed model consists of two main phases: the prescreening phase and the evaluation phase. The prescreening phase involves expert judgment-based assessment with qualitative criteria. The first phase uses absolute measurement analytic hierarchy process (AHP) to filter possible alternative interfaces to a reasonable subset. The evaluation phase involves user-based assessment such as user testing, with quantitative criteria. The objective of the second phase is to evaluate a subset of alternatives using objective measures and to select the best alternative. A set of criteria and measures for evaluating the usability of computer software designs is presented. The proposed methodology is demonstrated in the interface design of a database system used to analyze trip cases information of nuclear power plant.Relevance to industry

There is currently a focus on the usability of interactive computer software. Software developers, interface designers or human factors engineers often confront the task of comparative evaluation among systems, versions or interface designs. The proposed methodology provides practitioners with a structured approach to select the best interface based on usability criteria and measures.     

Using task analysis to improve usability of fatigue modelling software

The design of any interactive computer system requires consideration of both humans and machines. Software usability is one aspect of human–computer interaction that can benefit from knowledge of the user and their tasks. One set of methods for determining whether an application enables users to achieve their predetermined goals effectively and efficiently is task analysis. In the present study, a task analysis was applied to the graphical user interface of fatigue modelling software used in industry. The task analysis procedure allowed areas of usability improvement to be identified and then addressed with alternate interface prototypes. The present method of task analysis illustrates a practical and efficient way for software designers to improve software usability, user effectiveness and satisfaction, by involving users in the design process.     

An investigation on Ribbon interface design guidelines for people with less computer literacy

In the recent years, there is an intense competition between software development companies to design better interfaces. In this marketing rat race, Ribbon interface came to make software user interface easier. After the introduction of Ribbon by Microsoft, it was widely used by various software development companies. Ribbon is a replacement for menus and toolbars and it tends to organize tools in tabs based on their similarities. Although Ribbon interface has many advantages, previous researches have shown that there are serious usability issues that hinder usage of Ribbon interfaces for users with less computer literacy. In order to solve Ribbon interfaces usability issues, this study tried to introduce Ribbon interface design guidelines by focusing on the issues related to users with less computer literacy. In this study two separate sets of moderated (in-person) usability testing were used. The first set evaluated the usability issues of an experimental Ribbon interface software in terms of both visual and cognitive issues. The second set was used to evaluate the Ribbon interface prototype that was designed based on the discovered usability issues in the first usability test. In order to ensure the validity of the data, the researchers tried to triangulate the data collection process by collecting data from different sources, namely, quantitative measurement of participants' performance, direct observation, and interview. Based on the comparison of the usability tests results which points out the factors that have led to participants' performance improvement in the prototype version, a number of guidelines are extracted for Ribbon interfaces. These guidelines are applicable to Microsoft Office, Microsoft SharePoint and most of the software that can be developed with Ribbon interface. Putting these guidelines into action, self-learning would be promoted and learning issues of users with less computer literacy would be decreased.     

The application visualization system: a computational environmentfor scientific visualization

A software system for developing interactive scientific visualization applications quickly, with a minimum of programming effort, is described. This application visualization system (AVS) is an application framework targeted at scientists and engineers. The goal of the system is to make applications that combine interactive graphics and high computational requirements easier to develop for both programmers and nonprogrammers. AVS is designed around the concept of software building blocks, or modules, which can be interconnected to form visualization applications. AVS allows flow networks of existing modules to be constructed using a direct-manipulation user interface, and it automatically generates a simple user interface to each module
