摘要：
A system and a method are disclosed for identifying and characterizing a stress state of a user based on features of blood flow identified from optical signals. One embodiment of a disclosed system (and method) includes an optical sensing system to detect features of blood flow and identify and characterize a stress state of a user based on those blood flow features. Light transmitted or reflected from tissue of the user is measured by an optical sensor. A processor analyzes the received optical signal to identify features of the blood flow. The stress state of the user is determined based on the identified features. The stress state is characterized according to a type of stress, a level of stress or both. Additionally stress events are identified.
