UX-Based Design of A Mobile Application for Thai Seniors

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.
