    The Development of the Wireframes Design for Usability under the ISO 9241-151 Standard
    (2020-06-05)
    Charoenporn, Pattama
    This research aims to design a wireframe according to the usability test and the ISO 9241-151 standard. The procedure starts with collecting data from 400 website users with questions under the ISO 9241-151 standard and collecting data from interviews with Design Thinking technique from 20 web designers with evaluation interviews based on the System Usability Scale from 3 websites chosen as the sample space for data collection; namely sanook.com, kapook.com and dex-d.com. After analyzing the data from the sample group, a wireframe and site map is then built. Then, 5 experts will test the wireframe design based on the hypothesis created by the research. The results show that analysis of sample sites usage has a significant statistical relationship with wireframe design at level 0.05. With the System Usability Scale, wireframes and site maps have been designed to be assessed by 5 design specialists. Results appear that Header and Content design have been rated as Good by 3 specialists and Satisfactory by 2. Navigation and Information search was rated as Very Good by 2 and Good by 3. The content display has been rated as Very Good by 2 and Good by 3. Other topics have been rated as Very Good by 3 and Good by 2. Compiling those results conclude that this wireframe design is efficiently operational under the ISO 9241-151 standard, allowing design enthusiasts to collect information from this research to guide their future site designs. In the future, there should be some additional of other types of website design to cover more of the website designers' needs.

    Mobile technology has become a vital part of our lives. There is a large number of studies to develop mobile applications. Nevertheless, some of them were not designed for the elderly to use easily. By 2021, Thailand will become a full-fledged ageing society. Workers aged more than 45 will be at greater risk of losing their job because of economic recession or the growth of AI technology. This paper demonstrates the usability testing of mobile job applications comparing three popular job apps used in Thailand. An analytical tool for prototypes and the System Usability Scale (SUS) were used to collect and analyse data. The main usability metrics in this study are effectiveness, efficiency, and satisfaction. The results show that using ambiguous labels, icons with multiple meanings, and using a "hamburger" icon can cause Thai senior users to become disoriented and affect their performances.

    Usability tests of Thai mobile banking UI design
    (2020-01-01)
    Aranyanak, Inthraporn
    Nowadays, many banking customers process their transactions via mobile banking applications because of the convenience. This study examines five well-known Thai mobile banking applications to measure their usability and compares their UI design from the perspective of nine main functions. An analytical tool for prototypes and the System Usability Scale (SUS) were used to collect and analyse data. The usability test of the five mobile banking applications in this paper involves three usability metrics: effectiveness showing the completion rate, efficiency showing the time used to successfully complete a task, and satisfaction using SUS to evaluate users' satisfaction with the product. This paper presents problems found in poor UI design and suggests how to improve mobile banking UI design.
