Title:
SIGNAL PROCESSING SYSTEM, SENSOR SYSTEM, BIOLOGICAL MANAGEMENT SYSTEM, ENVIRONMENT CONTROL SYSTEM, SIGNAL PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/182249
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a signal processing system, a sensor system, a biological management system, an environment control system, a signal processing method, and a program that can increase system versatility and assess the autonomic nervous condition of a person. This signal processing system (2) comprises an exhaled air information acquisition unit (21) and a nerve assessment unit (23). The exhaled air information acquisition unit (21) acquires exhaled air information, which is biological information relating to the quantity of air exhaled by a person (H1). The nerve assessment unit (23) assesses the autonomic nervous condition of the person (H1) on the basis of variation in the exhaled air information.
