The purpose of this study was to evaluate the usability effectiveness of a webware for electronic theses and dissertations (ETDs) in Nigerian repositories. The webware (etdsearch.com.ng) is a web application system that curates ETDs from three sampled Federal government-owned universities. The system also links users to the repositories where the theses and dissertations are hosted.

The case study research strategy was adopted for the study. Sixty postgraduate students from three universities were randomly selected. A usability evaluation questionnaire based on the ISO 9241-11 framework was used to collect data after performing pre-defined queries/tasks based on the informational and transactional query models. The research questions were analysed using the median of the performance score (f_x) of the three universities for each item evaluated, while the Kruskall–Wallis test by ranks was used to test the null hypothesis at a 5% level of significance.

The study answered two research questions and tested two null hypotheses on the usability effectiveness of the webware based on the informational and transactional queries. The participants found the ETD search system effectively useable. In addition, there was no significant difference in the opinions of the participants.

The webware used simulated repositories as a feed bed for the ETDs in order to have control over the workability of the repositories. Thus, the results may differ slightly when “live” repositories are used.

The effectiveness of a webware that aggregates ETDs in Nigerian repositories will present libraries in Nigeria with evidence on how these systems work and can be improved upon.

There is a dearth of literature on practical usability studies of digital information systems in Nigerian libraries.

This paper aims to explore the use of tangible user interfaces for teaching concepts related to internet of things by focusing on two aspects, notably, usability and learning effectiveness.

To assess the usability of IoTTT, Nielsen’s principles were used due to its relevance and popularity for usability assessment. In the usability questionnaire, four attributes were evaluated, notably, learnability, efficiency, errors and satisfaction. As for evaluating learning effectiveness, learning assessment was conducted through pre-tests and post-tests. Two groups of 20 students participated where the first group attended conventional lectures on IoT, whereas the second group used IoTTT for learning same concepts. In the process, data was collected through the usability questionnaire and tests for usability and learning effectiveness assessment.

Results revealed a positive score for the usability of the TUI solution with an average rating of 3.9. Although this score demonstrated an acceptable solution, different issues were identified, based on which a set of recommendations have been made in this paper. On the other hand, in the common pre-tests, an average score of 6.40 was obtained as compared to a mean score of 7.33 in the post-tests for all participants. Knowledge gains were significantly higher for students who learnt IoT concepts through the TUI-based system where performance improved by 18 per cent.

The results revealed in this study are expected to help the research community, course designers and tutors comprehend the prospects of using tangible user interfaces to foster teaching and learning of IoT concepts. In addition, educational solution providers could consider commercialisation prospects of this technology to innovate in teaching and learning, while also building-up on limitations identified within this study.

This study aims to evaluate the usability of Google Drive (GD) in addition to measuring the effectiveness of GD and the challenges faced while using this cloud storage application among public library users of Lahore.

The study adopted a sequential explanatory mixed method design comprising the quantitative (QUAN) and qualitative (QUAL) parts. For the QUAN phase, a questionnaire survey was conducted among 384 users of public libraries through purposive sampling. For the QUAL phase, the think aloud technique was performed on several tasks during experiments and verbalized their thoughts and experiences while interacting with the system. The cloud usability model (CUM) was used to measure the “usability” of GD.

Findings indicated that most users were satisfied with GD's obvious features and inherent functions. QUAL results indicated that respondents did most tasks easily, whereas only some could complete the task.

The study is valuable as it is the first time used CUM to measure the perceived usability of GD. Second, the study used a mixed method study to get insights into perceived usability, effectiveness and challenges while using GD. The findings might be helpful for cloud support teams, including GD, as they can enhance certain features of usability, which lead to increased usage among users.

This research work is based on MPhil thesis.

The purpose of this study is to carry out a systematic literature review for evidence-based assessment of the effectiveness of thesaurus in digital information retrieval systems. It also aimed to identify the evaluation methods, evaluation measures and data collection tools which may be used in evaluating digital information retrieval systems.

A systematic literature review (SLR) of 344 publications from LISA and 238 from Scopus has been carried out to identify the evaluation studies for analysis, and 15 evaluation studies have been analyzed.

This study presents evidences for the effectiveness of thesaurus in digital information retrieval systems. Various methods for evaluating digital information systems have been identified. Also, a wide range of evaluation measures and data collection tools have been identified.

The study was limited to the literature published in English language and indexed in LISA and Scopus. The evaluation methods, evaluation measures and data collection tools identified in this study may be used to design more cognizant evaluation studies for digital information retrieval systems.

The findings have significant implications for the administrators of any type of digital information retrieval systems in making more informed decisions toward implementation of thesaurus in resource description and access to digital collections.

This study extends our knowledge on the potentials of thesauri in digital information retrieval systems. It also provides cues for designing more cognizant evaluation studies for digital information systems.

The construction site operates under a hazardous environment that requires a high level of understanding in building systems to minimise accidents. However, the current building education generally adopts paper-based learning approaches that lack hands-on experiences. Furthermore, to achieve Industrial Revolution 4.0 in line with any unforeseen pandemic, the most optimum solution is to transition from physical to technological-based building education. This paper aims to address the problems by proposing a game-based virtual reality (GBVR) for building utility inspection training.

The feasibility of the GBVR for building the utility inspection training approach is validated on a sample of undergraduate engineering students through user experience (survey) and performance-based comparisons against traditional paper-based training method.

The results show that the developed GBVR training has higher system usability in terms of visual output and knowledge retention than paper-based training due to visualisation technologies. The GBVR training method has also higher user-friendliness because of the higher motivational and engagement factors through the adoption of virtual reality and game-based learning.

GBVR training required a longer training duration and achieved a lower performance score (effectiveness) but can be improved by transitioning into hands-on tasks. This study has the potentials to be extended to vocational training platforms for competency development in the construction workforce by using cutting-edge extended reality technologies.

This paper portrays the benefits of integrating virtual reality technology in building education to overcome the low practicality and engagement of paper-based training.

Building on fundamental work on usability of workplaces, this paper aims to extend the perspective of usability as an approach in delivering workplace solutions. To explore the content and implications of usability, the concept is differentiated into two sub-concepts: usefulness and user-friendliness.

The theoretical rationale for the proposed conceptual specification is presented and explored using data from two independent research projects: a qualitative interview study in an office relocation project in Finland and a quantitative survey study of 1,420 office users of 43 buildings in Switzerland. The goal of the empirical research is to capture the elements of user experience connected to usability using the distinction between usefulness and user-friendliness.

The results from both studies show that perceived support of work activities by workspaces in relation to work tasks is the main element of usefulness. User-friendliness incorporates comfort and control as the two most important aspects. Correlations between usefulness and user-friendliness and outcomes of usable workspace design are low for self-assessed performance, moderate for job satisfaction and high for work area satisfaction.

Providing useful workplaces supports users’ job performance while designing for user-friendliness is correlated with user satisfaction.

The differentiation of usefulness and user-friendliness of office environments provides a new way to describe user experience. The integration of qualitative and quantitative research strategies strengthens the research evidence.

A previous article reported the usability evaluation of the information database called CUNY+ of the City University of New York (CUNY) in New York City, USA. This is a text‐based information system available on the wide‐area network in its various campuses for faculty, students and researchers. This present article describes the usability evaluation of this CUNY system’s Web and GUI version called the CUNY+ Web. A comparison of the results of both usability studies, and a description of the applicability of the previous usability instrument to this CUNY+ Web research is included.

This paper seeks to present a comparative study of the traditional usability‐testing process and the re‐engineered usability‐testing process for live multimedia systems.

Provides an overview of current usability‐testing techniques and usability laboratory configurations, and identifies some gaps in the traditional usability‐testing approach.

Traditional usability‐testing procedures are suitable for testing systems in the static environment but prove to be sub‐optimal in testing systems for dynamic (real‐time) environments.

The traditional set‐up is compared with innovative laboratory configuration, which consists of three computer systems: the test system in the middle augmented by two systems on either side that function as the scenario presenter and the data collection system. The re‐engineered usability‐testing process streamlined usability experiments and reduced the task completion times.

Despite a lot of agricultural initiatives by the government in a regionally diversified country like India, agriculture is poor, and farmer suicide cases are rampant. This study aims to socially transform and bring behavioural change among the farmers of southern India through the usage of new media. The research has gauged the factors that affect new media accessibility and usability, hindrances in the process and change of farmer’s behaviour through online social marketing bringing social transformation.

The study is action participatory in nature, and the data is triangulated by conducting a survey at the first level using the Delphi technique among 184 rural south Indian farmers who are smartphone users use new media, and at the next level, the farmers were requested to use WhatsApp for agricultural new sharing, and in the last stage, personal interview with entrepreneurs and farmers has been conducted to understand their new media adoption, e-learning and online social marketing.

New media is the best way to transform agricultural practices socially. It is a forum where all the farmers of the country can get together and address the issue of the agrarian crisis. Online social marketing (OSM) through WhatsApp is one of the best methods of behavioural change because different farmers can share their experiences and emotion for the crisis and give an appropriate solution to a problem. And, one of the most important features of OSM is it removes third parties from miscellaneous issues be it selling, buying or seeking and sharing information.

Despite trying to cover different hindrances in the way of social marketing of agriculture, the study is not free without its limitations. Language was a barrier, and this study require a lot of time to perceive the changes and adoption. Also, due to time constraint, the authors have categorically clubbed innovators, early adopters and early majority in the same layer opinion leaders and adopters of innovation. These could be analyzed separately in five layers, as suggested by Rogers (1995).

From the managerial perspective, the government should extend services that teach the agriculturists, farmers the use of new media. The marketers and makers of apps and software can tap into this business for launching products for farmers. We need apps designed only for farmers, where agricultural and farming practitioners all over the country and globe can interact about their products, conditions of agriculture and give solution to issues arising in agriculture and farming.

The researchers posit that there are hardly any studies that provide strategies to the agricultural and farming sectors in a regionally diversified country like India. The study is one of its first kind to propose new media strategies to reach out to the farmers of different regions and segmentation for a behavioural change and adoption of new media for better and sustainable agriculture. It has gauged into the factors that affect new media accessibility and usability among farmers and simultaneously gave strategy for behavioural change.

Online services have replaced many services that were delivered through other avenues. However, adoption of them has varied significantly. This paper seeks to expand on technology adoption theories by integrating them with those exploring service innovation and attempts to explore factors that help or hinder the attitude towards using online services. Thus, the study aims to provide insight into attributes to which developers and designers of such services should pay attention.

The study accomplishes the purpose stated above through testing a framework that was developed as a result of critical literature review, interviews, a brainstorming session, an expert focus group and a final large‐scale survey. A set of prototypes was developed as alternative interfaces for the online service.

In addition to finding that usefulness and ease of use are affecting the intention to use in the case of online services, the paper also identified that users were positively influenced by their acquaintances, commercials and related news about online ticket reservation positively. Self‐efficacy was also identified as a positive factor. However, a significant relationship between other elements of the user interface, such as task or user characteristics, could not be identified.

There is an increased interest in better service design and development. In the case of online services, developing better user interfaces by different technologies is critical, because capabilities of user interface add a lot to the information technology (IT) adoption process. So putting emphasis on better marketing and user training would help the adoption of online services.

There were a number of hypotheses that were not supported in the paper. Further data collection may help to explore the role of user and service characteristics better.

The study integrates technology adoption and market research theories to assess service innovation.
