1. A guiding apparatus, comprising:
- a vehicle-speed detecting unit for detecting a speed of a vehicle;
an object-candidate retrieving unit for retrieving a candidate object of interest existing in a vicinity of a guidance point, at which a driver of the vehicle needs guidance, on a travel path of the vehicle;
a recognizable-range estimating unit fordetermining a guidance distance required to provide guidance with respect to the candidate object of interest on the basis of (i) the vehicle speed detected by the vehicle-speed detecting unit and (ii) guidance output time required to provide guidance with respect to the candidate object of interest retrieved by the object-candidate retrieving unit, andestimating a recognizable range of the driver after the vehicle travels the determined guidance distance;
an object retrieving unit for retrieving, as an object of interest, the candidate object of interest when the candidate object of interest exists in the recognizable range estimated by the recognizable-range estimating unit; and
a guidance control unit for providing guidance with respect to the object of interest retrieved by the object retrieving unit.

Abstract
In a guiding method, an object of interest existing in a vicinity of a guidance point, at which a driver of a vehicle needs guidance, on a travel path of the vehicle is retrieved. A recognizable range the driver will have is estimated based on at least one of (a) time required to provide guidance with respect to the object of interest and (b) time required for the driver to visually check the object of interest after receiving the guidance. The guidance with respect to the object of interest is provided when the object of interest exists in the estimated recognizable range.

20. A guiding method, comprising:
-
retrieving an object of interest existing in a vicinity of a guidance point, at which a driver of a vehicle needs guidance, on a travel path of the vehicle; estimating a recognizable range the driver will have based on at least one of (a) time required to provide guidance with respect to the object of interest and (b) time required for the driver to visually check the object of interest after receiving the guidance; providing the guidance with respect to the object of interest when the object of interest exists in the estimated recognizable range.
