“…Usability assessment has been conducted in various aspects such as counseling [32], education [20,21,23,24,25,33], shopping [16,17], tourism [18], Web portal [15,19], and visual impairment study [24]. However, minimal pet-related studies concentrated on evaluating the usability in the multi-platform context.…”

<p class="0abstract">Usability evaluation is an essential activity to contribute to a higher standard of user experience. This study conducted a usability evaluation on multi-platform application according to usability attributes as defined in ISO 9241-11 standard which are efficiency, effectiveness, and satisfaction. The evaluation was conducted on both platforms; web and mobile application and involved 50 participants. The results discovered some points to usability issues. Therefore, to further enhance the users’ satisfaction, efficiency, and effectiveness, a set of improvement recommendations were proposed. Insights from this study provides a standard basis on the usability evaluation procedure which can serve as a guide for the usability evaluation of multi-platform applications.</p>

Mobile apps are fast emerging as assistive learning platforms for pre-schoolers, as well as junior school students. In fact, not just the parents but also the junior-level teachers encourage children to use mobile learning apps due to its many benefits such as interactive, enjoyable and informal, etc. Needless to say, the advent of mobile apps must also equitable for students with learning difficulties to take advantage of the same learning opportunities as other students. Students with learning difficulties suffer from disabilities in language, information processing, etc. that prevent them from performing their academic tasks in the same manner as other students. It is crucial to realize the development of mobile learning apps for students with learning difficulties requires inclusive designs that make the apps usable for them. The paper presents an evaluation of a mobile appDisleksia Belajar, which developed for students with dyslexia in junior school to learn the Malay language. Dyslexia is a common learning difficulty that causes problems with language processing e.g. reading and writing. The evaluation is performed using SUS and Fun ToolKit (v3) techniques, which intend to explore the usability and engagement of the mobile app. There is a total of 12 students with dyslexia aged 7 to 12 years old recruited as the participants. The findings contribute towards understanding and improvement for the future development of mobile learning apps for students that having similar difficulty.

“…It emphasizes the level users interact with mobile devices, ensures the acceptability of the application, provides ease of application usage, ensures effective and efficient application, and acts as an essential reference for improving the applications' design and features (Lynn et al, 2020). Heuristic evaluation is extensively used to validate system and application interfaces during and after development (Hussain and Omar, 2020). Jakob Nielsen proposed the heuristic evaluation method in 1994 and defined it as an evaluation method with between 3 to 5 trained HCI expert evaluators to examine a system or prototype according to established heuristic principles to check for problems and deficiencies with the application interfaces and rectify possible faults (J.…”

Financial technology (FinTech) has swiftly revolutionized mobile money as one of the ways of accessing financial services in developing countries. Numerous mobile money applications were developed to access mobile money services but are hindered by severe authentication security challenges, thus, forcing the researchers to design a secure multi-factor authentication (MFA) algorithm for mobile money applications. Three prototypes of native mobile money applications (G-MoMo applications) were developed to confirm that the algorithm provides high security and is feasible. This study, therefore, aimed to evaluate the usability of the G-MoMo applications using heuristic evaluation and usability testing to identify potential usability issues and provide recommendations for improvement. Heuristic evaluation and usability testing methods were used to evaluate the G-MoMo applications. The heuristic evaluation was carried out by five experts that used the 10 principles proposed by Jakob Nielsen with a five-point severity rating scale to identify the usability problems. While the usability testing was conducted with forty participants selected using a purposive sampling method to validate the usability of the G-MoMo applications by performing tasks and filling out the post-test questionnaire. Data collected were analyzed in RStudio software. Sixty-three usability issues were identified during heuristic evaluation, where 33 were minor and 30 were major. The most violated heuristic items were "help and documentation", and "user control and freedom", while the least violated heuristic items were "aesthetic and minimalist design" and "visibility of system status". The usability testing findings revealed that the G-MoMo applications' performance proved good in learnability, effectiveness, efficiency, memorability, and errors. It also provided user satisfaction, ease of use, aesthetics, usefulness, integration, and understandability. Therefore, it was highly recommended that the developers of G-MoMo applications fix the identified usability problems to make the applications more reliable and increase overall user satisfaction.
