METHOD FOR ESTIMATING STRESS FROM TEMPORAL WORK PATTERNS
First Claim
1. A computer-executable method for estimating a number of stress factors related to a worker, the method comprising:
- recording a sequence of work steps of the worker for a predetermined period of time;
extracting a number of temporal patterns (T-patterns) from the sequence of work steps;
calculating T-pattern statistics based on the extracted T-patterns;
applying a classification method on the calculated T-pattern statistics to produce a classification result; and
estimating one or more of the stress factors based on the classification result.

Abstract
One embodiment of the present invention provides a system for estimating a number of stress factors related to a worker. During operation, the system records a sequence of work steps of the worker for a predetermined period of time, and extracts a number of temporal patterns (T-patterns) from the sequence of work steps. Based on the extracted T-patterns, the system calculates T-pattern statistics, and applies a classification method on the calculated T-pattern statistics to produce a classification result. The system then estimates one or more of the stress factors based on the classification result.
