Health24: Health-related Data Collection from Wearable and Mobile Devices in Everyday Lives

We present an empirical study of collecting healthrelated data like sensor signals and lifelog from wearables and mobile devices. We have developed a health-related data collection framework for everyday lives, called Health24, composed of collecting data in a standard IoT platform from wearables like Galaxy watch, Apple watch, and Fitbit watch and smartphones like iPhone and Android phones. Raw sensor signal is collected from accelerometers, gyroscopes, and pressure sensors, and lifelogs such as activities and sleep time are extracted from smartphone- or cloud-supported APIs. Our study is designed to collect datasets from 300 subjects for 60 days in daily activities including sleep. We expect that health-related data could help people understand what aspects of the habits or activities in everyday lives will increase risk of disease and thus prevent it.
