Problems solved by technology

[0004] However, current products, especially smartphones and other terminal devices that can be held with one hand, are very difficult to zoom in and zoom out on the screen content of the current technology when held with one hand.
However, in the form of a terminal that can be held by a single hand, it will be inconvenient for users to operate it with both hands at the same time.

Embodiment approach

[0089] In this embodiment, it should be pointed out that when a single camera is used to implement the camera component, there may be blind spots in shooting, for example, when the distance between the finger and the camera is relatively far, or the angle is in the blind spot , just can't realize the effective shooting operation aimed at finger. Even so, within a certain range, it is possible to collect information through the camera and determine the image of the finger. Therefore, in the present invention, the imaging trigger operation area can be correspondingly set in the corresponding area.

[0090]This area is ideal for creating differential effects on the fingertips. As an example without limitation, the operating area can be a protrusion; it can also be a downwardly recessed area; or the surface friction degree of the corresponding position can be changed, for example, the friction degree can be increased or decreased. Then, by using the finger to operate in the indi...

Abstract

The invention provides a method and terminal for touch screen operation, belonging to the technical fields of electronics and software. The method includes the following steps: step 1, collecting the user's touch operation information for the dual-touch terminal; step 2, determining whether there is a touch movement operation for the front touch of the touch screen at the same time when the rear touch detection structure is in a triggered state, If there is, then go to the next step; step 3, determine whether the distance between the front touch position and the back touch position is a space expansion mode or a space reduction mode, and execute the zoom-in or zoom-out instruction of the screen display content according to the mode, or according to the The path mode of the front touch executes the zoom-in or zoom-out instruction for the preset screen display content of the path mode. Utilizing the present invention, the zoom-in and zoom-out operations of screen display content can be conveniently performed on the touch screen of the handheld terminal by means including holding with one hand.

Description

technical field [0001] The invention belongs to the technical fields of electronics and software. Background technique [0002] Touch screen technology is a widely used input and output method at present. For example, tablet computers and smart phones produced by Apple Computer Company all have touch screens at present. The use of touch screen technology reduces the area of ​​the keyboard on the original terminal equipment and increases the area of ​​the screen, enabling small-sized electronic products to obtain a larger display area. [0003] For example, in the terminal products of Apple Computer, the zoom-in and zoom-out operations of image content can be conveniently performed by using a touch screen and multiple fingers for operation. For example, by using two fingers to touch the touch screen at the same time, and then increasing the distance between them, the zoom-in operation of the content displayed on the screen can be obtained, and the zoom-out operation of the ...
