Database apparatus, attention calling apparatus and driving support apparatus
First Claim
1. A database apparatus comprising:
- a condition estimation unit capable of estimating a driver condition of a driver who is driving a vehicle;
an operation acquisition unit capable of acquiring an operation sequence of the vehicle by the driver;
a storage unit capable of storing the driver condition estimated by the condition estimation unit and the operation sequence acquired by the operation acquisition unit;
a concentration estimation unit capable of estimating a degree of concentration of the driver on driving operation by comparing the driver condition estimated by the condition estimation unit or the operation sequence acquired by the operation acquisition unit with the driver condition or the operation sequence stored in the storage unit; and
a control unit capable of performing a control for sequentially storing, to the storage unit for accumulation, the driver condition in association with the operation sequence when the degree of concentration estimated by the concentration estimation unit is determined, by the control unit, to have a value that is higher than a threshold.

Abstract
An attention calling apparatus operates in the following manner. That is, eyes distribution pattern is generated from the behavior of the eyes of the vehicle driver captured by a camera in a predetermined time, and driver'"'"'s condition is estimated based on the distribution pattern. Further, concentration of the driver on driving is estimated based on the comparison between the distribution pattern and the stored information of distribution pattern. When the distribution pattern indicates that the degree of concentration on driving is high, the driving operation is stored in storage in association with the concentration degree. When the operation situation fulfills a notification provision condition, driver'"'"'s attention is called depending on the concentration degree.
