Data collection for daily living activities and biometric information for estimating dweller's activity-dependent stress level toward QoL-aware appliance control

Abstract

Recently, evaluation of Quality of Life (QoL) in everyday life has been regarded as important. It will be possible to provide in-home services which improve QoL if the stress level of the dweller while performing daily activities (e.g., cleaning, cooking, etc.) which take temporal and physical burden is recognized during daily life. In this study, we analyze the stress level while performing daily activities by the LF/HF ratio known as a stress evaluation index based on heartbeat. As an experiment, we asked five participants to live in our smart home testbed wearing wearable device (Empatica E4 wristband) for four days each, and collected biometric data including heartbeat and volume pulse wave while recording activity labels. Through analysis of the collected data, we report the relation between the daily living activities and the stress index.
