Research on the Usability Evaluation Model of Mobile Application Interface Design for Active Senior

Advances in information technology and the COVID-19 that has been sweeping the world since 2019 have affected people’s lives and changed their consumption patterns in various ways, and the non-face-to-face consumption culture that has emerged from them has led to an increasing national usage rate of mobile applications. However, due to the initial aging of their bodies, the active elderly encounter difficulties in using mobile applications, such as the inability to use them smoothly due to the complicated design process or the difficulty in recognizing the font size, especially since the current mobile application interface is mainly designed with the younger generation in mind. Therefore, it is necessary to improve the usability of their mobile applications in order to make them use mobile shopping applications more easily and efficiently. Accordingly, the purpose of this thesis is to compile and summarize the characteristics of the active elderly and their mobile application status through the literature research method through relevant data and prior studies, and to grasp the main barriers to their use of mobile shopping applications. It also summarizes the visual elements of mobile shopping application interface into five elements: color, layout, icon, typography, and navigation. Secondly, based on the expert heuristic usability evaluation principles, specific usability evaluation principles are determined for the usability evaluation of mobile interfaces by combining the characteristics of active seniors, so as to establish a usability evaluation model of interface design that is relevant to active senior.
