Although the use of online authentication systems in banking services is expanding globally, little is known about cultural differences in forming consumers' responses to these services. This paper examines how the usability of an online security service and culture impact consumers' behaviour.

The authors conduct a 2 (usability: high vs low) × 2 (culture: US vs Korea) between-subjects, full factorial design.

The results indicate a differential influence of the usability of a security system by culture. In particular, US consumers exhibit greater behavioural intention in a high (vs low) usability condition, whereas Korean consumers showed more favourable responses in a low-usability condition. Moreover, perceived effort is confirmed as a crucial mediator that explains the psychological mechanism of the proposed effect.

This research contributes to the literature on online banking where security is an important determinant of success. Especially for managers involved in international banking services, the findings of cultural differences offer insights about the importance of local understanding and differentiation of bank services for specific target markets which can enhance consumers' response towards an online security service.

The current study is one of a very few attempts to examine the role of usability of an online security system in forming consumers' behavioural intention. More importantly, this study integrates the concept of culture to explain how usability influences positive or negative behavioural intention in an international market.

Guidelines for the design of knowledge-based e-learning usability systems are absent from the current recognized set of usability design heuristics and from an established evaluation methodology of e-learning system developments. Such systems can help Web designers and instructional designers design for different user needs and decide which properties are of a higher priority, thus meriting more design and development efforts. The authors aim to help students develop higher-order thinking skills, such as application, evaluation and syntheses of knowledge.

The authors applied Merrill ' s first principles of instruction and usability properties as pedagogical and usability design guidelines, knowledge management (KM) and hierarchical task analysis as methodological knowledge bases. The authors proposed a KM e-learning usability framework which frames our mapping of Web usability attributes to e-learning usability properties. The authors aim to investigate whether adopting Merrill ' s first principles of instruction and usability properties as knowledge-based guidelines/design factors would help learners develop higher-order thinking skills and whether this design would result in positive technology acceptance. The authors also developed a method matrix to map the selected methods of cognitive engineering to its potential uses in the KM e-learning usability framework of this paper and mapped e-learning usability tools with components in the KM e-learning usability system.

Findings indicated that our design effectively helped learners to demonstrate higher-order thinking skills and positive technology acceptance, promising indications toward the design and development of knowledge-based usability frameworks and systems.

The sample size of this paper is small. Hence, conclusions are not generalizable at this moment.

The authors’ contributions are twofold: First, the authors proposed a KM e-learning usability framework, which frames the mapping of KM processes to e-learning principles and usability properties. Second, the authors proposed a method matrix which maps the selected methods of cognitive engineering to its potential uses in their KM e-learning usability framework. Based on these mappings and focusing on the usability properties navigation and learning support, the authors used ICT/Web2.0 tools to present/visualize information more clearly and more sensibly/manageably to students, to help trigger new knowledge and develop higher-order thinking skills, such as application, evaluation and syntheses of knowledge and articulate information from different perspectives throughout the KM life cycle.

This research examined the factors affecting several types of student engagement, namely agentic, behavioral, emotional and cognitive engagement. Specifically, it examined the effect of e-learning system usability on student engagement and explored teacher behavior's possible intervening impact on this relationship.

Data were collected from 418 students studying at different specializations at Omani private academic institutions. This study employed a quantitative methodology and utilized the Smart-PLS for data analyses.

The findings showed that e-learning system usability influenced significantly and positively agentic, behavioral and cognitive engagement. However, the link between e-learning system usability and emotional engagement was not significant. Moreover, teacher behavior mediated the relationship between e-learning system usability and the four types of engagement.

This study improves one’s understanding of how the interaction of e-learning system usability and teacher behavior affects several aspects of student engagement. It also helps higher education administrators and policymakers by exploring the influential effects of e-learning systems usability and teacher behavior on facilitating students' engagement.

The objective of this research was to develop a new and highly accurate approach based on a fuzzy inference system (FIS) for the evaluation of usability based on ISO 9241-210:2019. In this study, a fully automated method of usability evaluation is used for interactive systems with a special look at interactive social robots.

Fuzzy logic uses as an intelligent computing technique to deal with uncertainty and incomplete data. Here this system is implemented using MATLAB fuzzy toolbox. This system attempted to quantify four criteria that correlate highly with ISO 9241-210:2019 criteria for the evaluation of interactive systems with maximum usability. Also, the system was evaluated with standard cases of computer interactive systems usability evaluation. The system did not need to train various data and to check the rules. Just small data were used to fine-tune the fuzzy sets. The results were compared against experimental usability evaluation with the statistical analysis.

It is found that there was a high strong linear relation between the FIS usability assessment and System Usability Scale (SUS) based usability assessment, and authors’ new method provides reliable results in the estimation of the usability.

In human-robot systems, human performance plays an important role in the performance of social interactive systems. In the present study, the proposed system has considered all the necessary criteria for designing an interactive system with a high level of user because it is based on ISO 9241-210:2019.

For future research, the system could be expanded with the training of historical data and the production of rules through integrating FIS and neural networks.

The purpose of this paper is to validate and measure the overall evaluation of electronic health record (EHR) and identify the factors that influence the health information systems (HIS) assessment in Brazil.

From February to May 2020, this study surveyed 262 doctors and nurses who work in hospitals and use the EHR in their workplace. This study validated the National Usability-focused HIS Scale (NuHISS) to measure usability in the Brazilian context.

The results showed adequate validity and reliability, validating the NuHISS in the Brazilian context. The survey showed that 38.9% of users rated the system as high quality. Technical quality, ease of use and benefits explained 43.5% of the user’s overall system evaluation.

This study validated the items that measure usability of health-care systems and identified that not all usability items impact the overall evaluation of the EHR.

NuHISS can be a valuable tool to measure HIS usability for doctors and nurses and monitor health systems’ long-term usability among health professionals. The results suggest dissatisfaction with the usability of HIS systems, specifically the EHR in hospital units. For this reason, those responsible for health systems must observe usability. This tool enables usability monitoring to highlight information system deficiencies for public managers. Furthermore, the government can create and develop actions to improve the existing tools to support health professionals.

From the scale validation, public managers could monitor and develop actions to foster the system’s usability, especially the system’s technical qualities – the factor that impacted the overall system evaluation.

To the best of the authors’ knowledge, this study is the first to validate the usability scale of EHR systems in Brazil. The results showed dissatisfaction with HIS and identified the factors that most influence the system evaluation.

The purpose of this paper is to investigate the usability of the user interface to an online catalogue and to explore how user assessment of both system usability and functionality can provide recommendations for the improved design.

Drawing on previous studies, the usability testing used a mixture of search tasks, interviews and a structured focus group. Representative users completed tasks designed to test the system's features and a “think aloud” protocol collected data about the users' responses when using the system and on its perceived functionality.

The analysis of the data on users' evaluation, preferences and expectations by a set of usability attributes enabled recommendations to be made with respect to key areas of the system functionality.

The usability study helped to improve the “look and feel” of the interface and demonstrates how the user expectation of what constitutes a supported experience can help make recommendations for the design of a system that is both usable and useful.

The paper demonstrates the benefits of using a mixture of approaches to test system usability and to gain a better understanding of usability from the perspective of the system's users, their expectations and perceived usefulness of the system.

This study aims to explore a framework for evaluating and comparing two federated search tools (FSTs) using two different retrieval protocols: XML gateways and Z39.50. FSTs are meta-information retrieval systems developed to facilitate the searching of multiple resources through a single search box. FSTs allow searching of heterogeneous platforms, such as bibliographic and full-text databases, online public access catalogues, web search engines and open-access resources.

The proposed framework consists of three phases: the usability testing, retrievability performance assessment and overall comparison. The think-aloud protocol was implemented for usability testing and FSTs retrieval consistency, and precision tests were carried out to assess the retrievability performance for 20 real user queries.

Participants were directed to assign weights for the interface usability and system retrievability importance as indicators for FST evaluation. Results indicated that FSTs retrievability performance was of more importance than the interface usability. Participants assigned an average weight of 62 per cent for the system retrievability and 38 per cent for interface usability. In terms of the usability test, there was no significant difference between the two FSTs, while minor differences were found regarding retrieval consistency and precision at 11-point cut-off recall. The overall evaluation showed that the FST based on the XML gateway rated slightly higher than the FST based on the Z39.50 protocol.

This empirical study faced several limitations. First, the lack of participants’ familiarity with usability testing created the need for a deep awareness and rigorous supervision. Second, the difficulties of empirically assessing participants’ perspectives and future attitudes called for mixing between a formal task and the think-aloud protocol for participants in a real environment. This has been a challenge that faced the collection of the usability data including user behaviour, expectations and other empirical data. Third, the differences between the two FSTs in terms of number of connectors and advanced search techniques required setting rigorous procedures for testing FSTs retrieval consistency and precision.

This paper has practical implications in two dimensions. First, its results could be utilized by FST developers to enhance their product’s performance. Second, the framework could be used by librarians to evaluate FSTs performance and capabilities. The framework enables them to compare between library systems in general and FSTs in particular. In addition to these practical implications, the authors encourage researchers to use and enhance the proposed framework.

Librarians can use the proposed framework to empirically select an FST, involving users in the selection procedures of these information retrieval systems, so that it accords with users’ perspectives and attitudes and serves the community better.

The proposed framework could be considered a benchmark for FST evaluation.

Earlier research has shown that human judgements, particularly retrospective as distinct from real‐time evaluations of painful experiences, are fundamentally flawed when superseded by other experiences. Describes a methodology for the evaluation of user experiences, assisted by a user‐centered co‐design tool for planning, creating and conducting wide‐ranging usability data acquisition throughout the system life cycle from inception to replacement. The results from the tests in this study were found to support the findings from recent cognitive psychology research on J/DM‐PPR theoretic biasing effects. The importance of the findings for software systems, and for interactive Web site development, is that if the interactive features which tax the user's patience and cognitive capability are not severely restraining, then users will be left with a better impression of the usability of the system than would be the case otherwise.

This study aims to explore whether the usability of user experience for mobile library application plays a mediating role in the relation between the success factors of information systems and net benefit.

The theoretical model of “information system success factor–user experience usability–net benefit” was constructed. A questionnaire was conducted at the Nankai University. The mediating effects of the usability of the mobile library application on information system success factors and net benefit were examined using hierarchical linear regression and structural equations.

First, the usability of user experiences is positively correlated to information quality, system quality and service quality. Second, user experience usability has a significant mediating effect on the relation between information system success factors and net benefit.

This study improves upon the DeLone and McLean model, connects the usability of user experience with the model and constructs the success factor mechanism of the mobile library application. It provides a theoretical basis for interpreting the relation between the mobile library application and users.

The purpose of the research is to investigate Norwegian web‐tutorials in contexts consisting of organizational issues and different forms of usability in relation to students’ perception and use of the system. Further, the research investigates the usefulness of the concepts concerning affordances and different forms of usability.

The research has employed a variety of data‐collection methods including interviews with librarians, interviews and focus group interviews with students, coupled with tests of their capabilities using the systems. A detailed research design is included in the paper.

In the organizational context, the research confirmed the importance of a close contact with teachers and disciplines and it was also clearly indicated that disciplines that supported an evidence‐based approach to research were much more active in using the tutorials as part of the requirements. Further, examples of organizational amnesia are discussed, pointing to the necessity for leadership support and systematic knowledge sharing. System Usability Scores are analysed in relation to solution of tasks and interesting relations are analysed. The perceptions of students were also interesting, clearly indicating marked differences in perceptions depending on study year and discipline but also different valuation of the different forms of usability. Overall, the research indicated a discrepancy between design intentions versus use and perception of the tutorials.

The theoretical approach has not been used often in library and information science research and the paper indicates its usefulness for further research. The findings presented in the paper also have implications for the way libraries design and promote information literacy tools.
