Abstract
Abstract A navigation system displays a route guidance list on a monitor screen in an intuitive and organized manner so that a user can easily understand information regarding the maneuvering locations and actions associated with the route to the destination. The route guidance list is structured in a layered manner so that the information regarding the maneuvering actions at the locations closer to the current user position will be prioritized. For example, in the route guidance list, the information regarding the immediate maneuvering location and action is more detailed, enlarged, and highlighted than the others. The navigation system displays the route guidance list in which the information regarding the maneuvering locations and actions will be dynamically changed in response to the changes of the current location of the user.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
146 words
A display method for a navigation system, comprising the following steps of: calculating a route to a destination specified by a user for performing a route guidance operation to the destination; detecting information concerning upcoming maneuvering actions between a current position of the user to the destination on the calculated route; and displaying a maneuver list which lists information associated with the upcoming maneuvering actions on the calculated route; wherein the maneuver list has a layered structure having two or more entries on a display screen in which the entries associated with maneuvering actions at the locations closer to the current position of the user are prioritized; and wherein each of the entries in the maneuver list includes a graphic representation of the maneuvering action and the prioritized entry is graphically enhanced by an increased size and more graphic indicators and icons than the other entries.
Claim 2
Dependent Claim
146 words
A display method for a navigation system, comprising the following steps of: calculating a route to a destination specified by a user for performing a route guidance operation to the destination; detecting information concerning upcoming maneuvering actions between a current position of the user to the destination on the calculated route; and displaying a maneuver list which lists information associated with the upcoming maneuvering actions on the calculated route; wherein the maneuver list has a layered structure having two or more entries on a display screen in which the entries associated with maneuvering actions at the locations closer to the current position of the user are prioritized; and wherein each of the entries in the maneuver list includes a graphic representation of the maneuvering action and the prioritized entry is graphically enhanced by an increased size and more graphic indicators and icons than the other entries.
Claim 3
Dependent Claim
35 words
The display method for a navigation system as defined in claim 1 , further comprising a step of changing the information in the maneuver list to reflect changes of the current position of the user.
Claim 4
Dependent Claim
51 words
The display method for a navigation system as defined in claim 1 , further comprising a step of monitoring a distance between locations at which the maneuvering actions are required and the current position of the user and changing the information in the maneuver list to reflect changes of the distance.
Claim 5
Dependent Claim
43 words
The display method for a navigation system as defined in claim 1 , wherein said step of displaying the maneuver list includes a step of displaying the information regarding the most immediate maneuvering action in more detail than that of other maneuvering actions.
Claim 6
Dependent Claim
62 words
The display method for a navigation system as defined in claim 4 , wherein said information regarding the most immediate maneuvering action includes a maneuver icon that shows a type of maneuvering action, a current position indicator that shows a current position of the user which moves on the maneuver icon in response to changes of the current location of the user.
Claim 7
Dependent Claim
44 words
The display method for a navigation system as defined in claim 1 , wherein said step of displaying the maneuver list includes a step of displaying the information regarding the most immediate maneuvering action in a size larger than that of other maneuvering actions.
Claim 8
Dependent Claim
50 words
The display method for a navigation system as defined in claim 1 , wherein said step of displaying the maneuver list includes a step of displaying a distance countdown meter when the current position of the user is within a predetermined distance range from the location requiring a maneuvering action.
Claim 9
Dependent Claim
53 words
The display method for a navigation system as defined in claim 7 , wherein said step of displaying the distance countdown meter includes a step of changing the distance countdown meter to reflect changes of distance between a location at which the maneuvering action is required and the current position of the user.
Claim 10
Dependent Claim
50 words
The display method for a navigation system as defined in claim 1 , further comprising a step of shifting the priority to a next upcoming maneuvering action once a current maneuvering action is completed by displaying the information regarding the next upcoming maneuvering action in a detailed and enhanced manner.
Claim 11
Dependent Claim
