Abstract

The invention discloses a touch method and a touch device for an electronic map. The method comprises the following steps of: receiving a delineation command of a target area of the electronic map displayed on a display screen; and performing corresponding operation on the delineated target area according to the received gesture touch command. By the method, the touch frequency of a user can be reduced, the time of the user can be saved, and the user can use the device conveniently.

Description

technical field [0001] The present invention relates to touch control technology, and in particular, to a touch control method and device for an electronic map. Background technique [0002] At present, the electronic map displayed on the display screen is usually enlarged or reduced according to the scale. The display screen can be a touch screen with a touch function, so that touch operations can be performed directly on the touch screen; in practical applications, touch Operations can also be performed on a device external to the display, such as a touchpad. When the place to be queried is located at the edge area of ​​the display screen, when the map is zoomed in, the place to be queried will not be displayed on the display screen. In this way, the user either needs to adjust the location to be inquired into the center area of ​​the display screen before zooming in on the map; or adjust the location to be inquired into the display screen after zooming in on the map. In...
