Driving analysis device and driving analysis method

A driving analysis method comprising:

• generating a time series of detection elements, the detection elements including a line-of-sight direction indicating to which of a plurality of preset viewable areas a line of sight of a driver driving a vehicle is oriented and an open/closed state of driver's eyes;
• acquiring evaluation data from the time series of the detection elements using a time window having a preset time width;
• extracting a plurality of feature quantities including at least a result of summation of appearance frequencies with respect to each of the detection elements from the evaluation data;
• and
• analyzing a driver's tendency by using a function receiving, as input, at least a part of the feature quantities extracted.
