“…A review of the related literature on usability of academic library websites showed that these studies had been generally carried out using methodologies other than cognitive walkthrough method [23][24][25][26] and this study was the first employing cognitive walkthrough method to meet the evaluation purposes.…”

With regard to the potential of huge knowledge dissemination by academic library websites, their usability is considered as a matter of great interest to university administrators as well as users. In the present study, a descriptive survey was designed aimed at evaluating usability of central library websites of type-1 universities of medical sciences in Iran in order to identify their usability issues and to provide inputs for possible remediation efforts to improve the design of similar websites in the future. The research procedure involved a library study to identify the tasks typically needed on library websites, use of the identified tasks to design a checklist for measuring three dimensions of usability (effectiveness, efficiency, and satisfaction), and finally a usability evaluation by two specialists of medical informatics and two librarianship experts. The given websites were rated “good” (60 % - 80 %) in terms of usability and no statistically significant difference was found between evaluations by different experts. It was concluded that more attention to website usability could improve users’ interest in services and facilitate realisation of goals in parent organisations. The results of this study could provide a basic framework for website design and improvement through giving proper attention to usability dimensions.

“…Efficiency was measured by the time task [61,62,63,64], while the effectiveness was measured by successful task completion [61,62] using a three-point scale (where 1 means “Participant completed the task successfully”; 2 means “Participant completed the task successfully with the help of the moderator” and 3 means “Participant provided the wrong answer or gave up before completing the task”). Satisfaction was measured by the standardised questionnaire System Usability Scale (SUS) [61,62] developed by the Digital Equipment Corporation. Participants’ satisfaction was measured by a five-point Likert scale (where 1 indicated that the participants totally disagreed with the sentence, while 5 indicated that the participants totally agreed with it) and then evaluated with the SUS protocol [65].…”

“…In accordance with the recommendations for usability testing procedure [62], the usability test was created and performed by an observational coding system called Morae. All three components of the system were used [62]: (1) Morae Recorder—used for the preparation and execution of usability testing; (2) Morae Observer—used for monitoring events on the participant’s screen and for the management of observational data; and (3) Morae Manager—used to manage data. Participants used the Morae Recorder for the entire time of the usability testing process, including questionnaires.…”

The existing body of knowledge reveals that customisable websites may lead to an increase in accessibility and usability for people with disabilities. In this way, the main goal of this research was to investigate how people with dyslexia respond to a customised version of a website in terms of its effectiveness, efficiency, satisfaction and suitability when compared to the default version of the website. The customisation of the investigated website was enabled with the aid of integrated assistive technology that offers people with dyslexia the opportunity to adjust a website themselves in accordance with their individual needs, demands and preferences. They can do this by changing the parameters, such as font size, font type and contrast between the background and text. The answers to the research questions were obtained with complementary research methods and techniques, including formal usability testing, thinking aloud protocol, log analyses, questionnaires and interviews. The empirical results show that participants experienced more issues when interacting with the default website, and they enjoyed more benefits when using the customised website. Too much information on the screen, not enough graphic elements, issues with visual appearance and inappropriately presented information were identified as the most common issues when interacting with the default website. When using the customised website, all participants agreed on a better user experience and, as the majority of them reported, this was due to appropriate contrast and font size. Additionally, the majority of participants also expressed desire to use the individual website adjustments regularly in the future. The conclusions of this investigation are that the individual website adjustments used in this research can not only help to minimise issues, but also eliminate challenges that people with dyslexia have when interacting with a website. Therefore, the primary contributions of this research are the empirical insights of interaction with both the default and customised version of the website for people with dyslexia. Furthermore, this research also has three secondary contributions: (1) detailed presentation and application the general usability evaluation procedure to a specific target group (people with dyslexia); (2) recommendations to adapt the usability evaluation methods for people with dyslexia; and (3) the usage of quantitative measurement instruments for the evaluation of a website’s usability and suitability for people with dyslexia.

“…Usability can be seen as a set of multiple constructs derived from various perspectives, such as effectiveness, efficiency, subjective pleasure, or memorability, with large focus on interface design (Jeng, 2006). Nielsen, who in the early 1990s, together with Rubin, developed usability engineering techniques for computer software design applied to Web design (Nielsen, 2003), establishes that usability "is a quality attribute that describes how easy user interfaces are to use" (Kous et. al., 2018).…”

Interactive Systems' User Interfaces can be considered as a special type of decision support system, as it exposes system's internal logic for supporting users' decision-making processes. Several evaluation methods can be used for investigating if the behaviour of a user interface complies with the best practices of human interface design. This paper investigates how Decision Support Systems methods and tools might assist in the analysis of Interactive System's User Interfaces. A research instrument is designed, as well as a multidimensional view of the data is created and presented. This work presents an alternative demarche for extending usability measurements of interactive interfaces, seeking to assist system designers and administrators in maintaining and improving their systems.
