Abstract: 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.

Abstract: In a consciousness determination device, a time series of a plurality of detection elements that includes a line-of-sight state indicating to which of a plurality of preset viewable areas a line of sight of a driver driving a vehicle is directed and an open/closed state of driver's eyes is generated. Detection data is extracted from the time series of the detection elements using a time window having a preset time width. The line-of-sight state of the driver with respect to each of the plurality of viewable areas is aggregated using the detection data. Based on an aggregation result, at least one of (i) a state of consciousness of the driver with respect to each of the plurality of viewable areas and (ii) a state of consciousness of the driver with respect to an event associated with each of the plurality of viewable areas is determined.

Abstract: A device includes: a chip; a support member; an adhesive layer disposed on the support member; and a wire electrically connected to the sensor chip on a side face of the sensor chip. Herein the adhesive layer includes a material exhibiting a dilatancy property in which a shear stress increases in a multi-dimensional function as a shear rate increases.
