Abstract: An information processor includes a route evaluation unit, a route selection unit, and a course creation unit. The route evaluation unit calculates route evaluation points for each of proposed routes in each of segments, on the basis of a condition of a road in the relevant one of the proposed routes. The segments are coupled between respective two nearest neighbors of a sequence from a starting point to a destination point through one or more via-points. The route selection unit selects, on the basis of the route evaluation points, one proposed route from the proposed routes for each of the segments. The course creation unit connects the proposed routes selected by the route selection unit, to create a course from the starting point to the destination point.

Abstract: An information processor includes a setting unit, a course creation unit, a course evaluation unit, and a course setting unit. The setting unit sets a starting point, one or more via-points, and a destination point. The course creation unit creates a course serially coupled between the starting point, the one or more via-points, and the destination point set by the setting unit. The course evaluation unit calculates course evaluation points based on a predetermined evaluation criterion, with respect to the course created by the course creation unit. The course setting unit sets the course as a proposed course for route guidance, on the basis of the course evaluation points.

Abstract: An information processor includes a course evaluation unit, a display controller, and a guidance course setting unit. The course evaluation unit calculates course evaluation points based on a predetermined evaluation criterion, with respect to a course serially coupled and created between a starting point, one or more via-points, and a destination point. The display controller provides display of the course and an indicator of the course evaluation points on the same screen. The guidance course setting unit sets the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

Abstract: An information processor includes an acquisition unit, a course setting unit, a registration unit, a detection unit, a first determination unit, and a controller. The acquisition unit acquires information regarding a via-point. The course setting unit sets a course from a starting point to a destination point through the via-point. The registration unit performs registration processing. The registration processing includes associating sound data with the via-point. The first determination unit determines whether or not a current position detected by the detection unit is within a predetermined range from the via-point. The controller makes an output control of the sound data associated by the registration processing, on the basis of a determination result by the first determination unit.
