A driving assistance apparatus includes: a driver identifying unit that identifies a driver driving a vehicle; an evaluation data obtaining unit that obtains, based on an identification result of the driver identifying unit, evaluation data on the driver's visual cognitive ability for an event that occurs when the driver is driving the vehicle; an event detecting unit that detects, on the basis of surrounding information data indicating a situation of the vehicle's surroundings, whether or not the event has occurred; and a processing unit that determines, in a case where the event has been detected and on the basis of the evaluation data on the driver, the evaluation data being related to the event, whether or not notification information is to be output from an output unit.

An eye tracking device includes at least one light source configured to irradiate detection light for eye tracking to at least one eyeball of a subject; at least one imager configured to capture image of the at least one eyeball; a position detecting unit configured to detect a position of a pupil center of the at least one eyeball and a position of a corneal reflex center of the at least one eyeball from the captured image; a gaze determining unit configured to determine whether the subject is gazing at a target position based on the position of the pupil center and the position of the corneal reflex center; and a calibration unit configured to perform calibration for the eye tracking based on the captured image when the gaze determining unit determines that the target position is gazed at by the subject.

Eye tracking device and eye tracking method

Validity of a line-of-sight direction detected by a gaze point detection unit is determined by using a positional difference that is a calibration value used for detecting a position of a corneal curvature center. Therefore, it is possible to easily and effectively determine the validity of the line-of-sight direction without additionally using a system or the like for detecting the validity of the line-of-sight direction. Consequently, it is possible to accurately detect line-of-sight directions of various subjects, such as a subject whose left and right eyeballs have different corneal curvature radii or a subject whose line-of-sight directions of left and right eyeballs are largely different due to the influence of strabismus or the like.
