Touch screen control method and user terminal

Abstract

The embodiment of the invention relates to the technical field of communication and discloses a touch screen control method and a user terminal. The method comprises recording a first position point and a second position point touched on a screen; determining the length of the straight line segment connecting the first position point and the second position point; determining the rotating direction when the perpendicular bisector of the straight line segment rotates to be parallel to an X axis or a Y axis by the minimum rotation angle; adjusting the size of the display image of the display screen according to the rotation direction and the length of the straight line segment. In application of the embodiment of the invention, a user only needs to touch two different position points on the screen with one finger, the user terminal can zoom in or zoom out the size of the display image of the screen, thus reducing the threshold for zooming in and zooming out the display image of the display screen and improving the user experience.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a touch screen control method and a user terminal. Background technique [0002] With the continuous development and maturity of communication technologies, users have more and more personalized demands on increasingly popular smart terminals, especially mobile terminals. Existing mobile terminals, especially portable mobile terminals, have relatively small screens, which are inconvenient for poor eyesight such as myopia, presbyopia or amblyopia, or when it is necessary to browse and observe text, pictures and videos on the screen in detail. Observe the picture on the screen. In practical applications, two fingers are usually used to touch the screen at the same time and perform a reverse sliding operation to realize the magnification of the display screen. This method requires the user to use two fingers at the same time, which invisibly raises the threshold for screen c...

Existing mobile terminals, especially portable mobile terminals, have relatively small screens, which are inconvenient for people with poor vision such as myopia, presbyopia or amblyopia, or when it is necessary to browse and observe text, pictures and videos on the screen in detail. Observe the picture on the screen

In practical applications, two fingers are usually used to touch the screen at the same time and perform a reverse sliding operation to realize the magnification of the display screen. This method requires the user to use two fingers at the same time, which invisibly raises the threshold for screen control.
