ABSTRACT
Under the background of COVID-19 epidemic, starting from the perspective of user satisfaction in the process of user's using news App, the research explores the relevant factors affecting user satisfaction based on the process of user's browsing news. Through user survey and literature research, combined with factor analysis method, the research sums up 13 factors affecting user satisfaction with the interface usability of news App. It uses decision-making experiment method to analyze and research 30 pcs of online and offline questionnaire data and draws cause and effect diagrams. Finally, it concludes that the three key factors affecting the user satisfaction with interface usability of news App are the factors: image, image-text layout, interface clarity;and the factor that affects other factors to a large extent is interface clarity. Finally, it clarifies the relationship among the relevant factors affecting user satisfaction with the interface usability of news App, further analyzes the problems existing in the current news App at the level of human cognition, and puts forward some relevant suggestions for the improvement of user satisfaction with the Interface Usability of news App.
ABSTRACT
In order to enable middle-aged and elderly groups to have a more efficient access to epidemic information when facing diseases, this paper takes covid-19 information as an example, 12 related factors interrelated to the efficiency have been selected through literature and user studies, amog which the key points and their correlation have been found out through decision-making trial and evaluation laboratory(DEMATAL). Results shows that the key elements that ultimately affect the epidemic information acceptance of middle-aged and elderly groups are content presentation, page readability and shareability;and the three factors that largely affect others are vision problems, page readability and page layout. Besides, the problems in the process of the middle-aged and elderly groups using mobile products to obtain information are further analyzed, and related countermeasures and suggestions for improvement are proposed. © 2020 IEEE.
ABSTRACT
Free from the limitations of time and space, online education achieves a rapid development in spite of the attack by COVID-19 in 2020. How to improve the user experience through optimizing the product's interactive design plays a significant role in enhancing the product quality. Based on UTAUT Model in combination with Flow Theory, this research examines the impact factor model and research hypotheses according to relevant questionnaire data from the perspective of interactive design. Corresponding results show that, Performance Expectancy and Flow Experience exert an obvious impact on users' continuous usage behavior while Content Quality, Interactive Experience and Visual Design impose an indirect impact. In the conclusion part, corresponding interactive design suggestions are proposed in reference to such research results in this paper. © 2020 IEEE.
