DRIVING ANALYSIS DEVICE AND DRIVING ANALYSIS METHOD

In a driving analysis device, an information generation unit generates a time series of 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. An acquisition unit acquires evaluation data from the time series of the detection elements using a time window having a preset time width. An extraction unit extracts 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. An analysis unit analyzes a driver's tendency using a function that receives, as input, at least a part of the feature quantities extracted by the extraction unit.
