Ratings and experiences in using a mobile application to increase physical activity among university students
Implications for future design
University students have low levels of physical activity and are at risk of mental health disorders. Mobile apps to encourage physical activity can help students, who are frequent smartphone-users, to improve their physical and mental health. Here we report students’ qualitative

Developing messaging content for a physical activity smartphone app tailored to low-income patients
User-centered design and crowdsourcing approach
Background: Text messaging interventions can be an effective and efficient way to improve health behavioral changes. However, most texting interventions are neither tested nor designed with diverse end users, which could reduce their impact, and there is limited evidence regardin

Adaptive learning algorithms to optimize mobile applications for behavioral health
Guidelines for design decisions
Objective: Providing behavioral health interventions via smartphones allows these interventions to be adapted to the changing behavior, preferences, and needs of individuals. This can be achieved through reinforcement learning (RL), a sub-area of machine learning. However, many c
