Earable ZEN: Development of an Earphone-Type Zazen Support Wearable System

Table 1

The threshold, variation when mouth breathing, and variation when nodding for each subject. The threshold for each subject was calculated using the measurement values acquired from the experiment in Section 3.2 with the method in Section 2.2. The variation for mouth breathing for each subject was obtained by the subject performing mouth breathing 10 times, seeking the maximum value each time, with the mean of the maximum value over 10 times being taken. The variation when nodding was obtained in the same way.
