Problems solved by technology

However, inputting addresses or dragging and dropping coordinates is not only cumbersome but also error-prone, causing users to repeatedly operate; in addition, when users are unfamiliar with the target address, they may not know the names or coordinates of the places to be detoured or passed by, and need to be displayed on the electronic map. The name or coordinates of the place to be detoured or passed by can only be determined by repeated queries on the Internet, which not only wastes the user's time, but also is inconvenient for the user to use

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...
