Abstract

An information processing apparatus may be implemented as a route navigator, which uses a route navigation method and a computer program product. A processing circuit is used to calculate respective passage frequencies of passageway segments in a passage history. The processing circuit then selects a navigation route to a destination, includes at least one passageway segment with a passage frequency that is a low or zero passage frequency.

Claims

a processing circuit configured to;

detect one of a plurality of user movement modes;

store a passage history for each of the plurality of user movement modes;

calculate passage frequencies of passageway segments in the passage history based on the passage history for each respective plurality of user movement modes; and

select a navigation route to a destination based on the detected one of a plurality of user movement modes, and further based on at least one passageway segment with a passage frequency that is a low or zero passage frequency.

2. The information processing apparatus of claim 1, wherein the processing circuit is further configured to:

send a search query to a remote device and receive data describing the navigation route that includes the passageway segment.

3. The information processing apparatus of claim 1, wherein

the passageway segment is a road.

4. The information processing apparatus of claim 1, wherein

the passageway segment is at least one of a pedestrian path and a sidewalk.

5. The information processing apparatus of claim 1, wherein

the passageway segment is a bicycle path.

6. The information processing apparatus of claim 1, wherein

the processing circuit sets a predetermined area that includes a current position and a destination, and selects the navigation route to be within the predetermined area.

7. The information processing apparatus of claim 6, wherein

a size of the predetermined area is expanded in accordance with a user-specified extra-time input.

8. The information processing apparatus of claim 1, wherein

the processing circuit selects the navigation route to coincide with a user-selectable location of interest.

9. The information processing apparatus of claim 1, wherein

the processing circuit selects the navigation route to coincide with a location of interest, the location of interest is selected from website provided information.

10. The information processing apparatus of claim 1, wherein the processing circuitry is further configured to:

select a user defined geographic search area on a map,

wherein selecting a navigation route is further based on the user defined geographic search area.

11. The information processing apparatus of claim 1, wherein the passage frequency is reset at a predetermined time interval.

12. A route navigator, comprising:

circuitry configured to;

selectably perform navigation searches in a first movement mode and a second movement mode,

when operating in the first movement mode, the circuitry identifies a navigation route that includes a passageway segment that is not included in another navigation route identified with the second movement mode and has a passage frequency that is below a predetermined threshold,

when operating in the second movement mode, the circuitry identifies the another navigation route according to a priority of at least one of a shortest distance and a shortest travel time, and

display the navigation route when the circuitry is operating in the first movement mode.

13. The route navigator of claim 12, further comprising:

circuitry configured to send a search query to a remote device, and receive data describing the navigation route that includes the passageway segment.

14. The route navigator of claim 12, wherein

the passageway segment is a road.

15. The route navigator of claim 12, wherein

the passageway segment is at least one of a pedestrian path and a sidewalk.

16. The route navigator of claim 12, wherein

the passageway segment is a bicycle path.

17. The route navigator of claim 12, wherein

the passage history is zero.

18. The route navigator of claim 12, wherein

the circuitry sets a predetermined area that includes a current position and a destination, and selects the navigation route to be within the predetermined area.

19. The route navigator of claim 18, wherein

when operating in the first movement mode, a size of the predetermined area is expanded in accordance with a user-specified extra-time input.

20. The route navigator of claim 12, wherein

the circuitry selects the navigation route to coincide with a user-selectable location of interest.
