CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from Japanese Patent Application No. 2019-157228, filed on Aug. 29, 2019, the entire contents of which are hereby incorporated by reference.

BACKGROUND

The technology relates to an information processor, an information processing method, a computer-readable recording medium, and an information processing system. Specifically, the technology relates to route guidance techniques for vehicle travel.

On-vehicle navigation devices have come in wide use. They offer a proposed route on a map, in response to an input of, for example, a starting point and a destination point. They also provide route guidance on travel.

Japanese Unexamined Patent Application Publication (JP-A) No. 2004-212160 describes a technique regarding a navigation device that searches routes in accordance with a driver's various requests.

SUMMARY

An aspect of the technology provides an information processor including a course evaluation unit, a display controller, and a guidance course setting unit. The course evaluation unit is configured to calculate 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 is configured to provide display of the course and an indicator of the course evaluation points on a same screen. The guidance course setting unit is configured to set the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

An aspect of the technology provides an information processing method including: calculating 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; providing display of the course and an indicator of the course evaluation points on a same screen; and setting the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

An aspect of the technology provides a computer-readable recording medium containing a program. The program causes, when executed by a computer, the computer to implement a method, the method including: calculating 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; providing display of the course and an indicator of the course evaluation points on a same screen; and setting the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

An aspect of the technology provides an information processing system including a server device and a display device. The server device includes a course evaluation unit and a transmission unit. The course evaluation unit is configured to calculate 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 transmission unit is configured to transmit, to the display device, information regarding the course and information regarding the course evaluation points. The display device includes a display controller and a guidance course setting unit. The display controller is configured to provide display of the course and an indicator of the course evaluation points on a screen, on the basis of the information transmitted by the transmission unit. The guidance course setting unit is configured to set the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

An aspect of the technology provides an information processor including circuitry. The circuitry is configured to calculate 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 circuitry is configured to provide display of the course and an indicator of the course evaluation points on a same screen. The circuitry is configured to set the course displayed on the screen as a course for route guidance on the basis of an operation by a user.

An aspect of the technology provides an information processing system including a server device and a display device. The server device includes first circuitry and a transmission unit. The first circuitry is configured to calculate 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 transmission unit is configured to transmit, to the display device, information regarding the course and information regarding the course evaluation points. The display device includes second circuitry. The second circuitry is configured to provide display of the course and an indicator of the course evaluation points on a screen, on the basis of the information transmitted by the transmission unit. The second circuitry is configured to set the course displayed on the screen as a course for route guidance on the basis of an operation by a user.
