1. A physical response record system comprising:
- a physical response recording unit for detecting and recording physical response of a driver of a vehicle as response data that reflects a mental condition of the driver;
an operation data recording unit for detecting and recording operation data of the vehicle;
a position detector for detecting and recording a vehicle position;
an imaging unit for imaging surroundings of the vehicle as a moving picture;
a risk response detection unit for detecting the physical response of the driver as a risk response based on periodical observations of the response data and the operation data, wherein the physical response is determined as the risk response when the operation data indicates an abnormal condition in response to variation of the response data that exceeds a predetermined value;
an analysis unit for analyzing the moving picture taken at and around a time of the risk response, wherein the analysis of the moving picture determines and categorizes at least one of a moving object and a fixed object existing around the vehicle; and
a storage unit for detecting a speed and a moving direction of at least one of the moving object and the fixed object relative to the vehicle based on the analysis by the analysis unit and for storing the speed and the moving direction of at least one of the moving object and the fixed object in association with the vehicle position detected by the position detector.

Abstract
A physical response record system includes a main unit and various sensors for recording driver'"'"'s conditions and vehicle operations by a driver. The driver'"'"'s conditions in combination with the vehicle operations are used to determine a risky situation of the vehicle based on an averaged driver'"'"'s condition and the like. The risky situation is further analyzed for detecting a risky object and stored as a record for later use.
