The use of MOOCs (Massive Online Open Courses) has become very popular in the past few years. Such courses can teach a large variety of skills, including the basics of virtual mobilities, both for students and teachers. The Open VMLH (Virtual Mobility Learning Hub) is an innovative multilingual environment which was created as part of the Erasmus+ Open Virtual Mobility project, with the purpose to promote collaborative learning, social connectivism and networking as an instructional method, OERs as the main content, and open digital credentials. In this paper, we will present the usability evaluation of the Open VMLH mobile application, a mix of heuristic and cognitive evaluation methods. Some of the issues discovered are related to the general interface and functionality of the mobile application, while others are related to the structure of the courses and the implementation of the content, but just a couple of them are critical for the user experience.

Low quality mobile applications have damaged the user experience. However, in light of the number of applications, quality analysis is a daunting task. For that reason, QDroid is proposed, an automated quality analyzer that detects the presence of crashes, excessive resource usage, and compatibility problems, without source codes and human involvement. QDroid was applied to 67 applications for evaluation and discovered 78% more crashes and attained 23% higher Activity coverage than Monkey testing. For detecting excessive resource usage and compatibility problems, QDroid reduced the number of applications that required manual review by up to 96% and 69%, respectively.

BACKGROUND Preoperative assessment reduces the risk of poor perioperative outcome and reduces cost of a specific group of perioperative candidates. The implementation of a preoperative digital tool may help to improve guideline adherence. MyPreOp®(Ultramed Ltd, Penryn, UK) is a web-based questionnaire designed to replace paper-based preoperative assessments. OBJECTIVE The study aimed to assess the user experience of MyPreOp®, investigate the factors affecting completion times, and devise a method of administering a validated usability scale without negatively affecting completion times. METHODS Anonymised datasets were extracted from the MyPreOp® system. The data collected included age, gender, American Society of Anesthesiology physical classification status, and time taken to complete the assessment. Two user experience evaluations were used: In Phase 1, two questions asking about overall experience and ease of use; and in Phase 2, a previously validated usability questionnaire, with its 20 questions equally distributed among five succeeding patient cohorts. There were 2593 respondents in total (Phase 1: n=1193; Phase 2: n=1400). RESULTS MyPreOp®scored well in both phases. In Phase 1, 80% of respondents had a good or better experience and 90% found it easy to use. The usability rating in Phase 2 was 4.13 (out of a maximum of 5) indicating high usability. Average completion time was 46.95 minutes (sd=25.83). The implementation of the longer usability evaluation scale in Phase 2 did not negatively impact completion times. Age and physical status were found to influence completion times but strength of the correlation was only moderate. CONCLUSIONS MyPreOp® rates high in both user experience and usability. The method of dividing the questionnaire into five blocks is both valid and does not negatively affect completion times. Further research into the factors affecting completion time is recommended.

User experience is a key quality of mobile application design. It involves all aspects of human–computer interactions, and thus the optimisation of user experience is a multi-objective optimisation problem. User experience is subjective and uncertain; however, very little attention has been directed toward this issue when optimising user experience. In this article, a grey-fuzzy-based Taguchi approach is proposed to optimise user experience in mobile application design. Design analysis is first conducted to determine mobile design patterns and user experience characteristics. Next, a Taguchi experiment is executed, and then the signal-to-noise ratios are computed. After that, the signal-to-noise ratios are transformed into a multi-response performance index via a grey-fuzzy-based analysis. Finally, based on the multi-response performance index, the optimal design is achieved by using statistical analysis. A mobile health application design was employed to illustrate the proposed approach. The results indicate that this approach can effectively manage the subjectivity and uncertainty concerning user experience characteristics, and can be used as a general robust design approach for optimising user experience of mobile application design.

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 Evaluation Methods

The usability of the mobile applications is the most important factor in developing, so the key to develop successful mobile applications is usability, especially for users have specific needs such as visually impaired. However, developers do not focus on visually impaired users. Moreover, there are limited studies and usability evaluation models for mobile applications for visually impaired so developers use just a modified usability evaluation methods which are not enough and useful to evaluate mobile applications for visually impaired, or they use general usability evaluation models. Therefore, using these methods or models is difficult for evaluator and not useful for visually impaired users. This study conducts Systematic Literature Review (SLR) to identify usability dimensions that help mobile applications developers and evaluators to evaluate mobile application for users which have moderate and severe visual impairment. The result shows that, six dimensions that have a significant impact on moderate and severe visually impaired users' satisfaction, who use mobile applications. These dimensions namely efficiency, effectiveness, satisfaction, errors, accessibility and understandability.
