A systematic review on usability evaluation methods for m-commerce apps
No full textThere are several literatures pertaining to the usability of mobile commerce (m-commerce) applications, however, these literatures do not sufficiently address issues about usability methods or adequately provide knowledge concerning usability methods used in most of the empirical usability evaluation for applications in m-commerce. Hence, this paper attempts to review available literatures with the aim of capturing the usability techniques commonly or frequently used in the domain of usability evaluation for applications in m-commerce. To achieve the stated research goal, the study applied systematic literature review methodology. Sixty seven (67) papers in the area of usability evaluation for m-commerce apps were downloaded. Out of these papers, twenty one (21) most relevant studies were selected for review in order to extract the appropriate information needed for the analysis. The results from the review reveal that heuristic evaluation, formal test and think-aloud methods are the most commonly utilized methods in m-commerce application usability evaluation compared to the cognitive walkthrough and informal test methods. In addition, most of the studies applied control experiment (33.30% of the total reviewed studies)other studies that applied case study in usability evaluation make up 14.28%. However, most of the studies reviewed, lacked comprehensive framework to demonstrate the applicability of other usability methods in m-commerce domain such as survey and field study. The results from this paper provide additional knowledge for usability practitioners, designers, developers, and the research community to know the current usability methods applied in m-commerce application evaluation
An application of the ISO/IEC 25010 standard in the quality-in-use assessment of an online health awareness system
No full textResearch studies show that there is an upsurge in the number of users surfing the Internet for online health related information. This increase in information seeking behavior on the Web gives rise to the need to ensure that Web based portals meet basic quality in use standards. The ISO/IEC 25010 standard was developed as a model for evaluating such quality in user expectations. In this paper, this standard was used to assess the quality in use of e-Ebola Awareness System, an online health awareness portal. The results provide some insights into the quality into the use of the online portal and also pointing to some issues that impact negatively on the quality in use of the portal, demanding attention and improvement
Usability metrics and methods for public transportation applications: a systematic review
No full textDevelopment of hearing-impaired evaluation model for mobile phone
No full textThis paper discussed on usability evaluation model for the hearing-impaired mobile applications. Mobile applications developed for the disabled (hearing-impaired) are usually being scanted in term of usefulness and accessible for the disabled group. Evaluating the usability of such application are difficult due to the reason not many current models focus on the requirements for disabled people. Thus, this paper has proposed usability evaluation model for the hearing-impaired mobile application so that usability issue in such application could be identified and ensure applicability for daily usage. The model helps mobile developer and interface evaluator to produce better mobile applications for disabled people
A metric-based evaluation model for applications on mobile phones
No full textA number of methods and measures have been used by researchers in software evaluation. Usability metrics is one of the approaches that has been used as a guideline to evaluate the quality of the system in many mobile applications. However, the metrics used for evaluation method keep changing due to new inventions of mobile phones. Thus, there is a need to create a dynamic model for evaluation that can grow together with new inventions and technology. In this paper, a dynamic usability metrics model for evaluation of mobile applications was designed. The model comprises usability goals, questions and metrics for evaluation of applications on mobile phones. To ensure that the model is reliable and effective, a usability study was conducted on two applications installed in different mobile phones. this model proves to be applicable for evaluation of mobile phone applications whereby its questions and metrics can be dynamically changed accordingly to comply with the requirements of the evaluators
Mobile video streaming applications: a systematic review of test metrics in usability evaluation
No full textIn evaluating the usability of mobile video streaming applications, the performance of the applications comes into focus. This is because the performance of mobile streaming applications affects their usability. From this study, video streaming and video quality are identified as the two most evaluated elements in the usability test of mobile video streaming applications. These elements are affected by several related factors that are peculiar to the mobile platforms and domains. These in turn affect the usability of the applications. In mobile platforms, bandwidth is low and network connections are unstablethis is coupled with the limitations caused by the smallness of the screen sizes of the mobile devices. Furthermore, startup delays, jitter, latency and re-buffering are the determining factors for the performance of mobile video streaming. On the other hand, video quality is determined by frame rate, bit rate, and resolution. These factors present themselves due to the mobile context of mobile streaming applications. They combine to influence the performance of the applications as well as their usability. Therefore, in considering the usability of these set of applications, these factors (metrics) are important as they determine the performance of the applications and by and large also affect the usability of the applications. Other factors identified in the study that affect the usability of mobile streaming applications include: functionality, social context and user interface and appearance. On the whole, this paper presents the results of a systematic review of test metrics in the usability evaluation of mobile video streaming applications. The systematic review approach used include: defining the search strategy, selection of primary studies, the extraction of data, and the implementation of a synthesis strategy. Using this methodology, 238 studies were foundhowever, only 51 relevant studies were eventually selected for the review. The study reveals that time taken for video streaming and the video quality were the two most popular metrics used in the usability test and evaluation of mobile video streaming applications. Besides, most of the studies concentrated on the usability of mobile TV as users switch from traditional TV to mobile TV
