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.
Claims25
An information processing apparatus comprising:
- a processing circuit that
- calculates respective passage frequencies of passageway segments in a passage history, and
- 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.
A route navigator, comprising:
- a search unit configured to selectably perform navigation searches in a first mode and a second mode,
- when operating in the first mode, the search unit identifies a navigation route that includes a passageway segment that is not included in another navigation route identified with the second mode and has a passage frequency that is below a predetermined threshold,
- when operating in the second mode, the search unit identifies the another navigation route according to a priority of at least one of a shortest distance and a shortest travel time;
- and
- a display control circuit that display the navigation route when the search unit is operating in the first mode.
An information processing method comprising:
- calculating with a processing circuit respective passage frequencies of passageway segments in a passage history, and
- selecting a navigation route to a destination, includes at least one passageway segment with a passage frequency that is a low or zero passage frequency.
A route navigation method, comprising:
- selectably performing with a search unit navigation searches in a first mode and a second mode,
- when operating in the first mode, identifying a navigation route that includes a passageway segment that is not included in another navigation route identified with the second mode and has a passage frequency that is below a predetermined threshold,
- when operating in the second mode, the identifying the another navigation route according to a priority of at least one of a shortest distance and a shortest travel time;
- and
- displaying with a display control circuit the navigation route when the search unit is operating in the first mode.
A non-transitory computer storage medium having instruction stored therein that when executed by a processing circuit perform an information processing method, the method comprising:
- calculating with the processing circuit respective passage frequencies of passageway segments in a passage history, and
- selecting a navigation route to a destination, includes at least one passageway segment with a passage frequency that is a low or zero passage frequency.
A non-transitory computer storage medium having instructions stored therein that when executed by a processing circuit perform a route navigation method, the method comprising:
- selectably performing with a search unit navigation searches in a first mode and a second mode,
- when operating in the first mode, identifying a navigation route that includes a passageway segment that is not included in another navigation route identified with the second mode and has a passage frequency that is below a predetermined threshold,
- when operating in the second mode, the identifying the another navigation route according to a priority of at least one of a shortest distance and a shortest travel time;
- and
- displaying with a display control circuit the navigation route when the search unit is operating in the first mode.
