Analysis of the Relationship between the Amount of Exercise and Unpleasantness in terrible twos using Sensor-embedded Plushie Device and Wearable Device

-A Trial of Causal Relationship Analysis Using Data of Toddler Physical Behavior-

Abstract

Parents’ childcare burdens, stress and worries are increasing as toddler grow up. Parents will prepare themselves if they are aware of the unpleasantness of their toddler the next day. This study aims to examine the causal relationship between behaviour and unpleasantness of toddler. Our research group has conducted two-week experiments where the systems for measuring the behaviour of toddler is monitored using the sensor-embedded plushie device, wearable device and emotion recognition in a real-life environment. The result of association analysis shows that the total amount of exercise do not have a large influence on unpleasantness. However, when the total amount of exercise exceeds the average value, the number of unpleasantness in the next day decreases. The cross-correlation analysis using data of sensor-embedded plushie device and the unpleasantness indicates that the peak of unpleasantness due to fatigue caused by playing with sensor-embedded plushie device comes about three hours later.
