The human–computer interaction (HCI) for mobile applications is becoming increasingly important as mobile applications have become an integral part of everyday life. Mobile app developers need to continuously improve the users’ experience to fulfill their conditions, which in turn, can trigger the purchase decision. Trust is another important factor, driving users to adopt mobile apps and use them to make online purchases. However, mobile app developers constantly face the dilemma between user trust and HCI experiences. This study’s primary purpose is to investigate the HCI and trust factors for the continued use of mobile payment apps and their services. Based on the human–computer interaction, task–technology fit, and IS success theories, an integrative framework is proposed to examine the relationships between continuance intention and its antecedents. An online survey was conducted to collect data from 544 mobile users. The results of the analyses indicate that trust plays a more significant role than HCI in increasing the users’ continuance usage of mobile payment services. As for improving HCI experiences for users, this study shows that system quality plays the most important role, followed by the skill of using mobile payment services and the perceived task–technology fit (TTF) for using the services. Information quality does not significantly impact the enhancement of positive HCI experiences. The results provide insights for the developers of mobile payment services to improve the user experience.

Since early 2020, the COVID-19 pandemic has had a devastating impact on global tourism. Vaccine tourism is a novel health tourism concept, which provides an opportunity for countries with a vaccine surplus to offer medical tourism packages to entice international tourists from countries with vaccine shortages to visit for sightseeing and receive vaccine inoculations. Understanding the factors that influence people to adopt vaccine tourism is one of the strategies that could boost a country’s tourism sector and help to revive the local economy. This study aims to examine the factors influencing the intention to adopt and recommend COVID-19 vaccine tourism among young travelers. A total of 179 questionnaire surveys were collected from traveling-related social media outlets. Partial least squares structural equation modeling (PLS-SEM) was performed to analyze the data. The results indicate that young tourists in Thailand are inclined to promote vaccine tourism to others. Price value appears to be the most significant influencing factor on intentions to both adopt and recommend vaccine tourism. Additionally, trust in the foreign healthcare system was positively associated with young travelers’ intention to recommend vaccine tourism to others. Theoretically, this research adds to the medical tourism literature, suggesting that, while trust is an important factor influencing the medical tourism decision, it appears to be insignificant in the context of vaccine tourism.

The 2021 military coup d’état in Myanmar and the Coronavirus (COVID-19) pandemic commencing at the end of 2019 have had major impacts on the already existing digital divide in this Southeast Asian country. This paper aims to explore the effects of these two events on the digital divide and their consequences on the learning practices of students in Myanmar. Following a broad review of relevant literature, primary data were collected from students in Myanmar about their use of IT for online learning and the outcomes. The raw data resulting from this field research has been shared with stakeholders who analyzed, evaluated, and commented on it during expert interviews. The main findings are: IT usage for online education among students in Myanmar is a matter of major concern. A majority of students nationwide have no access to computers. The IT skill level in the country corresponds to this finding and is only on an average level. Smartphones are more accessible but are often old or of lower quality. Internet connections are available but are vulnerable to disruptions initiated by the military regime. Therefore, it can be concluded that students in Myanmar in many cases did not have the technical equipment or skills necessary to learn effectively through the usage of IT during the national crises. Nevertheless, it can be stated that IT helped and was also supportive in sustaining and improving the well-being of students in Myanmar.

Background: Older adults who have difficulty moving around are commonly advised to adopt mobility-assistive devices to prevent injuries. However, limited evidence exists on the safety of these devices. Existing data sources such as the National Electronic Injury Surveillance System tend to focus on injury description rather than the underlying context, thus providing little to no actionable information regarding the safety of these devices. Although online reviews are often used by consumers to assess the safety of products, prior studies have not explored consumer-reported injuries and safety concerns within online reviews of mobility-assistive devices. Objective: This study aimed to investigate injury types and contexts stemming from the use of mobility-assistive devices, as reported by older adults or their caregivers in online reviews. It not only identified injury severities and mobility-assistive device failure pathways but also shed light on the development of safety information and protocols for these products. Methods: Reviews concerning assistive devices were extracted from the “assistive aid” categories, which are typically intended for older adult use, on Amazon’s US website. The extracted reviews were filtered so that only those pertaining to mobility-assistive devices (canes, gait or transfer belts, ramps, walkers or rollators, and wheelchairs or transport chairs) were retained. We conducted large-scale content analysis of these 48,886 retained reviews by coding them according to injury type (no injury, potential future injury, minor injury, and major injury) and injury pathway (device critical component breakage or decoupling; unintended movement; instability; poor, uneven surface handling; and trip hazards). Coding efforts were carried out across 2 separate phases in which the team manually verified all instances coded as minor injury, major injury, or potential future injury and established interrater reliability to validate coding efforts. Results: The content analysis provided a better understanding of the contexts and conditions leading to user injury, as well as the severity of injuries associated with these mobility-assistive devices. Injury pathways—device critical component failures; unintended device movement; poor, uneven surface handling; instability; and trip hazards—were identified for 5 product types (canes, gait and transfer belts, ramps, walkers and rollators, and wheelchairs and transport chairs). Outcomes were normalized per 10,000 posting counts (online reviews) mentioning minor injury, major injury, or potential future injury by product category. Overall, per 10,000 reviews, 240 (2.4%) described mobility-assistive equipment–related user injuries, whereas 2318 (23.18%) revealed potential future injuries. Conclusions: This study highlights mobility-assistive device injury contexts and severities, suggesting that consumers who posted online reviews attribute most serious injuries to a defective item, rather than user misuse. It implies that many mobility-assistive device injuries may be preventable through patient and caregiver education on how to evaluate new and existing equipment for risk of potential future injury.
