Zusammenfassung
This paper presents findings from our implementation of a context aware health guidance system for obese individuals, with a focus on smartphone- and smartwatch-based health monitoring and participant adherence. To aid participants in weight loss, our system utilizes data from wearables and smartphones, integrating nutrition tracking and gamification elements into a smartphone application and a web-based health dashboard for health coaches. Eight participants completed a 120-day field study to evaluate the system and examine user adherence to health monitoring and the effectiveness of gamification in a weight loss program. Data on steps, sleep, heart rate, weather, and manually logged meals were collected. Adherence varied across data types, with step counts being the most consistently collected, while sleep and heart rate data were limited due to inconsistent smartwatch usage.
