Abstract

A method, system, device, and computer readable medium for a displaying a predicted route of a user. It can be determined whether a predicted route is within a displayed range of the map. If the predicted route is not within the displayed range of the map, the displayed range of the map can be automatically changed such that the predicted route is within the displayed range of the map.

send a second location of the user to the at least one server;

receive, from the at least one server, at least one second predicted destination different from the first predicted destination and having been determined based at least in part on historical information regarding the user and the second location of the user; and

determine whether the at least one second predicted destination is within the display range of the map, and, if the at least one second predicted destination is not within the display range of the map, automatically change the display range of the map, based on the at least one second predicted destination and based on the determination that the at least one second predicted destination is not within the display range of the map, such that the at least one second predicted destination and the first predicted destination are within the display range of the map.

14. The device of claim 13, further comprising a location acquiring unit that determines the first location of the user.

15.
