Abstract

Sufficient physical activity can reduce many adverse conditions and contribute to a healthy life. Nevertheless, inactivity is prevalent on an international scale. Improving physical activity is an essential concern for public health. Reminders that help people change their health behaviors are widely applied in health care services. However, timed-based reminders deliver periodic prompts suffer from flexibility and dependency issues which may decrease prompt effectiveness. We propose a fuzzy logic prompting mechanism, Accumulated Activity Effective Index Reminder (AAEIReminder), based on pattern recognition and activity effective analysis to manage physical activity. AAEIReminder recognizes activity levels using a smartphone-embedded sensor for pattern recognition and analyzing the amount of physical activity in activity effective analysis. AAEIReminder can infer activity situations such as the amount of physical activity and days spent exercising through fuzzy logic, and decides whether a prompt should be delivered to a user. This prompting system was implemented in smartphones and was used in a short-term real-world trial by seventeenth participants for validation. The results demonstrated that the AAEIReminder is feasible. The fuzzy logic prompting mechanism can deliver prompts automatically based on pattern recognition and activity effective analysis. AAEIReminder provides flexibility which may increase the prompts’ efficiency.

Summary

Introduction

Physical activity substantially benefits physical and mental health. Regular and moderately intense physical activity, such as fast walking and running, can increase life expectancy and contribute to a healthy life. Improving physical activity has become an essential concern for public health worldwide [1,2]. Health care providers can deliver a prompt such as a text message, voice, or image to assist people in managing their health. Periodic prompts can be delivered at various intervals, such as daily or weekly, and they can be sent through various channels, such as a short message service or telephone. The use of prompt applications has been widely applied in health care services and has positively affected patient self-management, weight loss, and physical activity [3,4]
