Laugh Log: E-Textile Bellyband Interface for Laugh Detection and Logging

摘要

Laughter is said to be linked to satisfactory human relationships and to have a positive impact on health, hence it is often related to perceived improvements in the quality of life. In this paper, we focused on the stomach to detect natural laughter resulting from funniness, which is positive even in laughter. Consequently, by measuring the pressure change in the abdomen using a textile sensor we can build a wearable laugh log system capable of detecting and recording laughter. In our pilot experiment, we conducted experiments that induce laughter under environmental settings and examined a deep learning method to detect laughter in a period within the measured log. Results demonstrated the possibility of detection of laughter in a controlled environment. We then simulated daily scenes that were likely to trigger laughter, and then we measured and examined the detection of laughter through deep learning.
