Method of generating a suggested navigation route based on touch input received from a user and related portable electronic device

摘要

A method of generating a suggested navigation route with a portable electronic device includes presenting a map to a user on a touch-sensitive screen of the portable electronic device, and receiving touch input from a user stroking the touch-sensitive screen from a touch-down location corresponding to a starting point on the map to a release location corresponding to an ending point on the map for indicating a location of a preferred route, the preferred route beginning with the starting point and finishing with the ending point. The method further includes generating the suggested navigation route by selecting streets for the suggested navigation route according to the preferred route in order to closely approximate the preferred route, presenting the suggested navigation route to the user on the touch-sensitive screen, and providing navigation assistance to the user for guiding the user along the suggested navigation route.
