Navigation system and route setting method
First Claim
1. A navigation system comprising:
- an image display unit at which various images including a map are displayed;
a touch panel operation detection unit that detects a touch panel operation performed by a user based upon a contact position at which the user has touched the image display unit;
a specified road detection unit that detects a road segment specified by the user by tracing a corresponding road portion present in the map, based upon a locus of the contact position resulting from the touch panel operation detected by the touch panel operation detection unit; and
a route setting unit that extends the detected road segment along a direction in which the road portion has been traced by the user and sets the extended road segment as a route to follow;
wherein;
if a length of the contact position locus resulting from the touch panel operation is equal to or greater than a predetermined specific value, the route setting unit sets the extended road segment as the route; and
if the length of the contact position locus is less than the specific value, the route setting unit sets the detected road segment as the route.

8. A method for setting a route in a navigation system, comprising:
-
displaying any of various types of images, such as a map, at a display monitor; detecting a touch panel operation performed by a user based upon a contact position at which the user has touched the display monitor; detecting a road segment specified by the user by tracing a corresponding road portion present in the map, based upon a locus of the contact position resulting from the touch panel operation; extending the detected road segment along a direction in which the road portion has been traced by the user; and setting the extended road segment as a route to follow;
wherein;if a length of the contact position locus resulting from the touch panel operation is equal to or greater than a predetermined specific value, the extended road segment is set as the route; and if the length of the contact position locus is less than the specific value, the detected road segment is set as the route. - View Dependent Claims (9, 10, 11, 12, 13, 14)
