BACKGROUND The COVID-19 pandemic, which began in the first quarter of 2020, necessitated the imposition of public health restrictions and the shutting down of the global economy. To slow down the spread of the coronavirus, governments worldwide rolled out nationwide contact tracing apps (CTAs) to notify people that may have been exposed to COVID-19...
Article
Background: The uptake of the deployed contact tracing apps worldwide has been low and slow. While a lot of research has been conducted on technology acceptance, little has been done to show the benefit of incorporating persuasive principles in these apps to increase effectiveness and adoption. Objective: The objective of this research is to inv...

Research shows that a well-designed user interface is more likely to be persuasive than a poorly designed one. However, there is a limited understanding of the relationship between user-experience (UX) design attributes and users’ receptiveness to the persuasive features of a persuasive technology aimed at motivating behavior change. To bridge this...
Article
Full-text available
People respond to different types of health messages in persuasive health communication aimed at motivating behavior change. Hence, in human factors design, there is a need to tailor health applications to different user groups rather than change the human characteristics and conditions. However, in the domain of fitness app design, there is limite...
Article
Physical inactivity has been recognized as one of the leading risk factors that account for many non-communicable diseases, with the World Health Organization labeling it as the fourth leading risk factor for global mortality. This has led researchers and developers to create fitness apps to support and motivate people to engage in physical activit...
Article
Background: Following the onset of the COVID-19 pandemic, digital contact tracing apps (CTAs) have become prevalent worldwide in a coordinated effort to curb the spread of the coronavirus. However, their uptake has been low and slow due to their minimalist design and lack of motivational affordances. Objective: The objective of this article is to...
