Aiming at a user-oriented approach in software evaluation on the basis of ISO 9241 Part 10, we present a questionnaire (IsoMetrics) which collects usability data for summative and formative evaluation, and document its construction. The summative version of IsoMetrics shows a high reliability of its subscales and gathers valid information about differences in the usability of different software systems. Moreover, we show that the formative version of IsoMetrics is a powerful tool for supporting… Expand
Objective Learnability Estimation of Software Systems
TLDR
The approach to the problem is presented, an instrument for calculating objective learnability out of times of completion is introduced, and results of a user study conducted to test adequacy of the method are revealed. Expand
Measuring web usability using item response theory: Principles, features and opportunities
TLDR
A standardised scale to measure usability in e-commerce websites using item response theory (IRT) is developed and opens a new field of research in the ergonomics of interfaces with respect to the development of scales using IRT. Expand
No need to read: Developing a pictorial single-item scale for measuring perceived usability
TLDR
The PSIUS represents an initial attempt to provide a nonverbal approach to the summative evaluation of technical systems, with the pictorial scale showing strong correlations with sum scores of established usability scales such as the System Usability Scale (SUS) and the Post Study SystemUsability Questionnaire (PSSUQ). Expand
The theoretical foundation and validity of a component-based usability questionnaire
TLDR
A component-specific questionnaire for measuring the perceived ease-of-use of individual interaction components and a theoretical framework is presented for this compositional evaluation approach, which builds on Taylor's layered protocol theory. Expand
Pictorial System Usability Scale (P-SUS): Developing an Instrument for Measuring Perceived Usability
TLDR
A first attempt to provide a pictorial usability scale for the evaluation of (mobile) devices and strong correlations were obtained for the sum scores between verbal and pictorial SUS, and the pictorial scale was perceived as more motivating than the verbal questionnaire. Expand
Comparing Four Softwares Based on ISO 9241 Part 10
TLDR
The results of the study show that compared with the mentioned three softwares, Iran’s hospital information system enjoys an average ergonomic quality and is recommended that the users’ comments and expectations be considered more when information systems are designed and developed. Expand
The Evaluation of Hospital Information System Usability and Its Effectiveness on Customers' Satisfaction Based on ISO 9241-10
The study aimed at determining whether there is any relationship between Careware (Hospital Information System) usability and customer satisfaction (Patient). It also aimed at identifying anyExpand
Approach for the development of systematic and productive verifying lists of usability
TLDR
An approach to the development of checklist-based software-usability inspection techniques is proposed, shaped as a cyclic process of planning, construction, application and data analysis, which involves the application of evolutive checklist versions. Expand
Construction and Evaluation of a User Experience Questionnaire
An end-user questionnaire to measure user experience quickly in a simple and immediate way while covering a preferably comprehensive impression of the product user experience was the goal of theExpand
Comparison of Questionnaire Based and User Model Based Usability Evaluation Methods
TLDR
How valid a usability evaluation method could assess the ‘extent to which a product can be used by specified users’ (ISO 9241-11) to facilitate software design becomes an interesting question to explore. Expand
