PROBLEM TO BE SOLVED: To improve accuracy in determining whether or not to output a warning at a traffic intersection.SOLUTION: A navigation device 10 comprises a position detection unit 11, a visual line detection unit 12, a storage unit 13, and a control unit 14. The position detection unit 11 detects a current position. The visual line detection unit 12 detects a direction of the visual line of a user 2e on the basis of an imaged image. The storage unit stores a three-dimensional model 2 that indicates an intersection area containing roads 2a, 2b, 2c and a building 2d. The control unit 14 uses the three-dimensional model 2 to determine whether a road recommended to enter is seen, among the roads 2a, 2b, 2c and the building 2d, from the current position toward the direction of the visual line and determines whether or not to output a warning on the basis of a determination result. |
