Risk evaluation system using people as sensors

Abstract

Disclosed is a risk evaluation system that uses people as sensors, wherein a control unit ( 21 ) in a stress management system ( 20 ) obtains mental health information and records same in a measurement information database ( 25 ). The control unit ( 21 ) then specifies a pattern in a reference pattern database ( 24 ) and obtains the measurement information relating to this pattern from the measurement information database ( 25 ). The control unit ( 21 ) in the stress management system ( 20 ) then revises a standard pattern based on individual attributes or work attributes. Next, the control unit ( 21 ) performs pattern matching and determines whether or not attention is required. If the determination is that attention is required, the control unit ( 21 ) presents an alert and an advice. This enables work, organization, and member risks to be appropriately evaluated based on changes in mental health information for a user.

 means for comparing transition of the statistic and transition of the mental information of each user engaged in the business operation; and   means for outputting an alarm for each user based on the comparison result.   
     
     
         8 . The risk evaluation system according to  claim 4 , further comprising:
 means for comparing transition of the statistic and transition of the mental information of each user engaged in the business operation; and   means for outputting an alarm for each user based on the comparison result.   
     
     
         9 . A risk evaluation system comprising:
 a measurement unit configured to measure mental information of each user;   a measurement information storage unit configured to store the mental information of each user time-sequentially;   a pattern information storage unit configured to store a reference pattern serving as information of transition of the mental information;   a business management information storage unit configured to store constituent information of a business operation carried out by a group and each user engaged in the business operation; and   a control unit, the control unit being configured to:
 obtain mental information of each user from the measurement unit to register the obtained mental information in the measurement information storage unit; 
 obtain transition of mental information of each user engaged in the business operation based on the constituent information; 
 compare the reference pattern stored in the pattern information storage unit to the transition of the mental information; and 
 output an alarm for the business operation based on the comparison result. 
   
     
     
         10 . The risk evaluation system according to  claim 9 , wherein the control unit is further configured to:
 calculate a statistic of the group using mental information of each user engaged in the business operation based on the constituent information;   obtain, from the pattern information storage unit, a reference pattern relating to transition of the statistic;   compare the reference pattern and the transition of the calculated statistic; and   output an alarm for the business operation based on the comparison result.   
     
     
         11 . The risk evaluation system according to  claim 9 , further comprising:
