Description

Method and device for realizing one-handed touch screen

technical field

Embodiments of the present invention relate to mobile terminal technologies, and in particular to a method and device for implementing a one-handed touch screen.

Background technique

With the development of science and technology, the screens of mobile terminals are getting bigger and bigger, and people have to use both hands to operate the mobile terminals at the same time. However, in daily life, it is unavoidable to hold the mobile terminal in one hand and do other things with the other hand. For example, when a user is on the subway, he can only hold the mobile terminal with the other hand while holding the subway lever with one hand. At this time, if the user's hand is fixed at the bottom of the mobile terminal screen, it becomes very difficult to touch the application on the top of the screen.

At present, many manufacturers have also launched optimization solutions for one-handed operation of large-screen mobile terminals. For example, double-click on the bottom button of the mobile terminal to concentrate the content of the application interface at the bottom of the mobile terminal screen, or click on the bottom of the mobile terminal screen. Trigger the area to shrink the application interface proportionally, or use your finger to pull down the application interface on the screen of the mobile terminal to move the content on the upper part of the application interface to the bottom, and so on.

However, the above one-handed operation is relatively mechanized and not easy to operate.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

first embodiment

Fig. 1 is a schematic flowchart of a method for implementing a one-handed touch screen provided by the first embodiment of the present invention. The method of this embodiment can be executed by a device for implementing a one-handed touch screen configured in a terminal, which can be implemented through hardware and/or or software, which is not limited. As shown in Figure 1, the method of this embodiment specifically includes the following steps:

Step 11. Detect and acquire the first movement trajectory of the user's finger moving above the preset boundary area on the touch screen of the terminal;

Wherein, the preset boundary area is an area in the touch screen, which can be customized by the user, for example, it can be a rectangular area in the touch screen, or the upper left corner area of the touch screen, the upper half of the touch screen area, and the like. Wherein, the terminal may be a mobile terminal, such as a smart phone, a tablet computer, and the like.

The above steps detect and acquire the movement trajectory of the user's finger moving above the touch screen, that is, the movement trajectory of the user's finger suspended above the touch screen for a certain distance but not touching the touch screen.

Specifically, in the prior art, a layer of electrode voltage, that is, capacitance, is generally covered on the touch screen of a mobile terminal (such as a mobile phone). When the user's finger approaches the touch screen, the capacitance under the finger will generate changes, and the capacitance located farther below the finger does not change because there is no conductor similar to the finger. Based on the above working principle, the movement track of the finger hanging above the screen moving on the terminal touch screen can be detected.

The threshold of the distance can be set, and when the finger and the touch screen are close to the set distance, it is confirmed that the movement track can be recognized. The first movement track is the movement track of the user's finger after entering the preset boundary area.

Step 12: Control the terminal to switch to a one-handed touch screen mode according to the first motion trajectory.

Specifically, since the user pre-sets a bounded area on the terminal touch screen, when the movement track of the user's finger moving above the preset bounded area on the terminal touch screen is detected, the terminal can be controlled to automatically switch to single mode according to the first movement track. Hand touch screen mode, such as setting track conditions, when the first movement track meets the set track conditions, the mode switch is triggered.

In this embodiment, by setting a preset limit area on the terminal screen, and controlling the terminal to automatically switch to the one-handed touch screen mode according to the detected motion trajectory of the user's finger moving above the preset limit area on the terminal touch screen, it can be accurate, Automatically recognize the user's operation intention, and no longer need the user to start the one-handed touch screen mode by touching the terminal or a button on the terminal, making the one-handed touch screen operation more intelligent, which greatly facilitates the user's operation and satisfies the User needs.

The preset boundary area can be set by the user at any time, preferably on the basis of the above-mentioned embodiment, the above-mentioned method also includes:

According to the user's limit area setting request, detect and acquire the second movement trajectory of the user's finger moving on the touch screen;

The second motion trajectory is set as a boundary of the bounded area.

Specifically, before the user has the need to switch to one-handed operation (for example, when the user is on the subway, holding the subway lever with one hand and holding the mobile terminal with the other hand), the user can pre-set a virtual boundary on the terminal. , which serves as the boundary of the bounding region. For example, the user can slide a boundary on the touch screen with a finger at the boundary outside the screen hot zone where the finger can easily control the terminal, that is, the second motion trajectory, and then set the motion trajectory as the boundary area of the boundary area. boundary. For operational reliability, the limit area setting request can be triggered by the user inputting a setting button or command, so as to avoid misoperation.

By setting the above-mentioned second motion trajectory as the boundary of the boundary area, it is convenient for the subsequent user to operate with one hand, and the control terminal is automatically switched to the one-handed touch screen mode, which is convenient for the user's subsequent operation.

Similarly, in order to avoid erroneous recognition of the user's operation intention, or to avoid repeated mode switching, based on the above-mentioned embodiments, before detecting and acquiring the first movement track of the user's finger moving above the preset limit area on the touch screen of the terminal, Also includes:

When it is detected that the position of the user's finger is within the preset limit area on the touch screen of the terminal, a message for prompting the user whether to activate the one-handed touch screen mode is displayed.

Specifically, when it is detected that the position of the user's finger is within the preset boundary area on the touch screen of the terminal, a message for prompting the user whether to activate the one-handed touch screen mode is displayed for the user to choose whether to activate the one-handed touch screen mode. mode, when it is determined that the user has selected to start the one-handed touch screen mode, control the terminal to switch to the one-handed touch screen mode; otherwise, do not start the one-handed touch screen mode.

On the basis of the above embodiments, the preset trajectory condition that the first movement trajectory needs to meet is preferably a trajectory that conforms to the user's single-handed operation habit. For example, when a typical right-handed mobile phone is operated, when the thumb of the right hand needs to click the icon in the upper left corner of the screen, it will be difficult to operate with one hand. At this time, it is necessary to switch to the one-handed touch screen mode. Correspondingly, the upper left corner area of the touch screen can be set as the set position, and the operation of controlling the terminal to switch to the one-handed touch screen mode according to the first motion trajectory can specifically include:

judging whether the movement trend of the first movement track is approaching the set position of the touch screen;

If yes, control the terminal to switch to the one-handed touch mode.

Among them, the corresponding relationship between various motion trends and set positions is preset in the terminal, and the corresponding motion trend can be determined according to the first motion trajectory, and the corresponding motion trend of the motion trajectory can be determined further according to the corresponding relationship between the motion trend and the set position. Whether the movement trend is approaching to the set position of the touch screen. For example, the setting position is the upper left corner, and when the user's finger approaches the upper left corner, the terminal is controlled to switch to the one-handed touch mode. The above technology is more in line with the user's one-handed operation habit, and can make the one-handed mode switching more timely and accurate.

The boundary of the preset boundary area is preferably a horizontal dividing line located in the middle of the touch screen. The upper part of the touch screen is the preset boundary area. The setting of this area also considers the user's one-handed operation needs. When the user needs to extend the finger to the upper part, it will be difficult to operate, and it is necessary to switch to the one-handed operation mode. .

For the specific implementation of the one-handed touch mode, the embodiment of the present invention also provides a preferred solution, that is, on the basis of the above-mentioned embodiments, controlling the terminal to switch to the one-handed touch screen mode according to the first motion trajectory specifically includes :

When it is recognized that the first movement trajectory meets the preset trajectory condition, determine the tangent direction of the arc at the current moment of the first movement trajectory;

The application icon on the touch screen is controlled to shrink in a direction opposite to the tangent direction.

Wherein, the preset trajectory condition may be that the finger slides for a preset time or a preset distance after exceeding the boundary of the preset limit area. The movement of the user's finger is usually continuous, and the moment when the acquired first movement trajectory meets the preset trajectory condition is taken as the current moment, and the subsequent movement trajectory of the user may not be considered. Wherein, the tangent direction represents the direction in which the user's finger is about to slide. When it is recognized that the first motion trajectory meets the preset trajectory condition, the application icon on the touch screen is controlled to shrink along the direction opposite to the tangential direction, which is usually the position where the user holds the terminal, toward Shrinking icons in this direction allows users to easily touch application icons with their fingers.

Wherein, shrinking may be reducing the size of the application icon or controlling the application icon as a whole to move in a direction opposite to the tangential direction until the user touches a desired application icon.

Alternatively, another switching method of the one-handed touch screen mode is, on the basis of the above-mentioned embodiments, controlling the terminal to switch to the one-handed touch screen mode according to the first motion trajectory specifically includes:

Select any two points on the first trajectory;

determining a motion vector of the user's finger according to the two points;

Controlling the application icon on the touch screen to shrink along a direction opposite to the motion vector.

The above solution also considers the user's operating habits. When switching to the one-handed touch screen mode, the application icon is shrunk to the position where the user may hold the terminal for click operation.

second embodiment

Step 21: When it is detected that the position of the user's finger is within the preset boundary area on the touch screen of the terminal, display a message for prompting the user whether to activate the one-handed touch screen mode. When the user chooses to start the one-handed touch screen mode, step 22 is performed, otherwise, the process ends.

For example, as shown in Figure 2b, the horizontal median line in the middle of the touch screen in the figure is the boundary line of the preset boundary area, wherein the hot zone touched by the user's finger is below the boundary line, that is, the area that the user can touch with one hand The area above the boundary line is an area that is difficult or impossible for users to touch with one hand. When it is detected that the position of the user's finger hovers over the area above the boundary line, a message for prompting the user whether to activate the one-hand touch screen mode is displayed for the user to choose.

Step 22: Detect and acquire the first movement trajectory of the user's finger moving above the preset limit area on the touch screen of the terminal;

Step 23. Select any two points on the first trajectory;

Step 24. Determine the motion vector of the user's finger according to the two points;

For example, as shown in FIG. 2c, it is determined that the direction of the motion vector of the user's finger is the upper left corner.

Step 25, controlling the application icon on the touch screen to shrink in a direction opposite to the motion vector.

For example, as shown in Figure 2c, when it is determined that the motion vector of the user's finger is moving to the upper left corner, it can be preliminarily determined that the user wants to click the application icon in the upper left corner, and then the application icons on the entire interface are scaled down by a certain value, and at the same time Move the entire interface to the lower right corner to cater to the user's click.

This embodiment realizes that the one-handed operation mode can be started automatically without increasing the user's manual operation steps, and controls the application icon on the touch screen to shrink along the direction opposite to the motion vector of the user's finger, so that the user Smoothly click to the screen area that was originally difficult to touch, which is convenient for users and meets user needs.

Step 31 : Detect and acquire a first movement trajectory of the user's finger moving above the preset boundary area on the touch screen of the terminal.

Step 32 , judging whether the movement trend of the first movement track is approaching the set position of the touch screen. If yes, execute step 33, otherwise end.

Step 33. Determine the tangent direction of the arc at the current moment of the first movement trajectory when it is recognized that the movement time of the user's finger in the preset boundary area reaches the preset time;

Step 34, controlling the application icon on the touch screen to shrink in a direction opposite to the tangent direction.

This embodiment realizes that the one-handed operation mode can be started automatically without increasing the manual operation steps of the user, and by determining the tangent direction of the motion track arc of the user's finger in the preset boundary area at the current moment, and controlling the touch screen The application icon shrinks along the direction opposite to the tangent direction, so that the user can smoothly click to the screen area that is originally difficult to touch, which is convenient for the user and meets the user's needs.
