Abstract
An information provision apparatus (1) comprises an observed-object detection apparatus (11) and an information output unit (41), and outputs from the information output unit (41) information on an observed object detected by the observed-object detection apparatus (11). The observed-object detection apparatus (11) comprises: a line-of-sight detector (21) for detecting a line of sight of a driver; an object detector (22) for detecting an object which is on a line of sight of a driver, based on the direction of the line of sight detected by the line-of-sight detector (21), on a current position of a vehicle, and on map information; and an observed-object calculator (23) for determining from objects detected by the object detector (22) an observed object observed by a driver, based on time for which the object is on a line of sight. This allows an object observed by a driver to be detected even if there is no trigger from the driver.
