NAVIGATION APPARATUS, NAVIGATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To allow a guide object to perform joining by a joining period, and to present joining conditions at appropriate timing even if the guide object does not become conscious.SOLUTION: A navigation apparatus includes: a unit for acquiring distance between two points for calculating distance between two points; a reference distance operation unit for calculating reference distance as remaining time until a joining period becomes shorter; a limit distance operation unit for calculating limit distance where joining is disabled when joining is not performed immediately by an appropriate moving means; and a joining condition presenting unit for determining whether joining conditions should be presented when the distance between the two points is not more than the reference distance or the limit distance.
