Apparatus and method for displaying route in personal navigation terminal
First Claim
1. A route guidance apparatus of a personal navigation terminal, the route guidance apparatus comprising:
- a road structure information storage unit for storing information related to road structures, the road structures including at least two of crosswalks, uphill roads, downhill roads, viaducts, underpasses, railway crossings, tunnels, construction zones, and alleys with no sidewalks;
a user preference information storage unit for storing at least one road structure preference representing a preference of a user related to the at least one road structure; and
a controller for determining a current location of the personal navigation terminal, computing routes to a destination from the current location, and selecting a user-preferred route from among the routes based on the at least one road structure preference.

Abstract
Disclosed is a route guidance apparatus of a personal navigation terminal, which includes a road structure information storage unit for storing information related to road structures, a user preference information storage unit for storing at least one road structure preference representing a preference of a user for the road structures, and a controller for determining a current location of the personal navigation terminal, computing routes to a destination from the current location, and selecting a user-preferred route preferred by a user from among the routes based on the at least one road structure preference. In the route guidance apparatus, a personal navigation terminal displays routes based on user preferences reflecting user characteristics instead of simply displaying the shortest route, thereby causing a user to take a proper route according to one'"'"'s own characteristics and degree of fatigue.

17. A route guidance method of a personal navigation terminal, the route guidance method comprising the steps of:
-
storing at least one user preference for road structures and public transportation; determining a current location of the personal navigation terminal; when a public transportation preference is received from the user, determining to use the public transportation; computing routes using the public transportation and routes excluding the public transportation to the destination from the current location; selecting a user-preferred route from among the computed routes with reference to the at least one user preference; displaying the user-preferred route and receiving a selection whether to use the public transportation from the user after the selected user-preference route; and displaying an undated user-preferred route according to the selection regarding whether to use the public transportation. - View Dependent Claims (18, 19, 20, 21)

22. A route guidance method of a personal navigation terminal, the route guidance method comprising the steps of:
-
storing at least one user preference for road structures and a public transportation; determining a current location of the personal navigation terminal; computing and displaying a shortest route to a destination from the current location based on the road structures and the public transportation; when the road structures are received from the user after computing the shortest route, computing a user-preferred route based on the received road structures; and displaying the computed user-preferred route. - View Dependent Claims (23)
