Unobtrusive respiration monitoring is a clinically important issue although the respiratory rate has been referred to as a “neglected vital sign” [1]. An abnormal respiratory rate including high, low, or no respiration (tachypnea, bradypnea, or apnea) can be utilized as an indicator of potentially serious physiological distress such as exacerbation of chronic obstructive pulmonary disease, cardiopulmonary arrest, and admission to the intensive care unit [2,3]. Moreover, since office workers spend three-fourth of their working hours sitting [4], an unobtrusive respiration monitoring during sedentary behavior may be beneficial to develop a system for early detection of the individual's serious physiological distress.

Conventional respiration monitoring performed by spirometry, pneumography, plethysmography, etc., is accurate [5]. However, it is obtrusive, inconvenient, and uncomfortable so impractical for long-term respiration monitoring. Although wearable devices including an accelerometer are more comfortable than...
