Problems solved by technology

Existing user terminals, especially portable user terminals, have relatively small display screens. For poor eyesight such as myopia, presbyopia, or amblyopia, or when it is necessary to browse and observe text, pictures, and videos on the display screen in detail, the It is not convenient to observe the screen of the display screen
In practical applications, two fingers are usually used to touch the display screen at the same time and perform a reverse sliding operation to realize the enlargement of the display screen. This method requires the user to use two fingers at the same time, which invisibly improves the display screen. Display screen adjustment threshold

Embodiment approach

[0106] The generation module 3052 is further configured to generate a zoom-out operation instruction when the recognition module 3051 recognizes that the type of the rotation direction is counterclockwise;

[0107] The obtaining module 3053 is also used to respond to the zoom-out operation instruction, and obtain the preset coefficient bound to the pressure value range to which the average pressure value belongs as the zoom-out coefficient;

[0108] The processing module 3054 is further configured to reduce the size of the display screen of the display screen according to the reduction factor.

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a human-computer interaction method and a user terminal. The human-computer interaction method comprises the following steps: recording the starting point, the terminal point and the average pressure value of a continuous track input on a display screen; determining a first straight line passing through the starting point and the terminal point simultaneously; determining a second straight line passing through the starting point and parallel to an X axis or a Y axis; determining a rotation direction of the first straight line, which rotates by the minimum rotation angle and is overlapped with the second straight line; and adjusting the size of the display picture of the display screen according to the rotation direction and the average pressure value. By means of the embodiment of the invention, the user terminal can amplify or reduce the display picture of the display screen only when a user inputs the continuous track on the display screen by using one finger; therefore, the threshold of zooming in and zooming out the display picture of the display screen can be reduced; and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a human-computer interaction method and a user terminal. Background technique [0002] With the continuous development and maturity of communication technology, the increasingly popular smart terminals, especially user terminals, have more and more personalized needs of users. Existing user terminals, especially portable user terminals, have relatively small display screens. For poor eyesight such as myopia, presbyopia, or amblyopia, or when it is necessary to browse and observe text, pictures, and videos on the display screen in detail, the It is not convenient to observe the screen on the display screen. In practical applications, two fingers are usually used to touch the display screen at the same time and perform a reverse sliding operation to realize the enlargement of the display screen. This method requires the user to use two fingers at the same time, whic...
