Description

Method and device for realizing cursor positioning in browser

technical field

The invention relates to the technical field of electronic products, in particular to a method and device for realizing cursor positioning in a browser.

Background technique

At present, almost all TVs use the remote control to control and operate the browser. On the one hand, due to the low sensitivity of the remote control, it is extremely inconvenient to use the remote control to control the browser; on the other hand, the remote control needs to move the cursor to the link point. It takes multiple keystrokes to operate the browser, and the positioning is very inaccurate. The TV field in the prior art also discloses several other ways to move the cursor to control the browser, such as controlling the browser through a wireless mouse, controlling the browser by connecting the mobile phone to the TV, and installing a touch screen on the remote control. You can control the browser by using the board, control the browser by shaking the remote control, control the browser by gesture recognition, etc. However, there are more or less deficiencies in these methods;

1. Control the browser with a wireless mouse: It is convenient to use a wireless mouse to move the cursor in the browser, but when exiting the browser, the user needs to use the remote control to operate, which allows the user to use multiple devices to control the TV, which deviates from the simple The principle of ease of use and entertainment for users;

2. Control the browser by connecting the mobile phone to the TV: the TV screen is transmitted to the mobile phone through the screen transmission, and the user controls the TV on the mobile phone, but this method is slow to respond when the network environment is poor; and some mobile phone screens are relatively large. Small, the webpage links appear densely packed on the phone screen, and the links cannot be clicked accurately;

3. Install a touchpad on the remote control to control the browser: Due to the limited area of the installed touchpad, moving the cursor on a large screen such as a TV requires multiple slides to move to the target link area, and fine-tuning is required to move the cursor accurately. To the target link, the operation is more cumbersome;

4. Control the browser through the motion-sensing remote control: the motion-sensing remote control is also called "air mouse", "air mouse" can make the cursor change position with the shaking of the remote control, but there is a problem of inaccurate positioning ;

5. Control the browser through gesture recognition: This method has requirements for the standardization of actions and operating distance, and when many people are making gestures at the same time, TV recognition will be greatly interfered, and gesture recognition is also There is a problem of inaccurate positioning.

Through the above analysis, it is found that the current methods of controlling browsers in the TV field generally have the problem of inaccurate positioning, and the above-mentioned 3, 4, and 5 all need to be realized by adding other components to the original hardware, which increases the production cost. .

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Embodiment one

Embodiment 1 of the present invention provides a method for realizing cursor positioning in a browser, as shown in FIG. 1 , including:

S0: Receive user button information;

In this embodiment, when the browser is opened by the user, S0 starts to be executed;

S1: Determine whether the cursor is on the browsing page, if yes, execute S2, otherwise return to S0;

S2: Detect the type of the key, if it is an arrow key, execute S3, if it is a confirmation key, execute S4, if it is another key, return to step S0;

Specifically, the direction keys in this embodiment include an up key, a down key, a left key, and a right key;

S3: Set the first scanning area on the browsing page according to the current cursor position, scan all the link points in the first scanning area according to the direction keys, and position the cursor on the link point that meets the requirements according to the user's operation, execute the link point, return S0;

S4: Set the second scanning area on the browsing page according to the current cursor position, scan all the link points in the second scanning area, position the cursor on the link point closest to the current cursor position, execute the link point, and return to S0.

As shown in Figure 2, between S1 and S2 described in the method of this embodiment includes:

S1': Determine whether the key type is a call key, if yes, execute S1'', otherwise execute S2;

The calling key in this embodiment can be a shortcut key (such as a long press of the OK key) or a calling key on the browsing page;

S1'': Generate a thumbnail of the web page structure by automatically identifying each main area of the browsing page, call out the thumbnail, and move the cursor when receiving information that the user selects an area in the thumbnail Go to the main body area corresponding to the selected area in the thumbnail, and return to S0;

In this embodiment, there may be multiple main body areas on one browsing page. When the user opens multiple browsing pages at the same time, move the cursor to a specific main body area in a certain browsing page through S1' and S1''. In S3 and S4, the scanning area is directly set in the main body area, which can realize more accurate positioning of the cursor;

Before S4 in this embodiment, it includes: S4': judge whether the cursor has positioned the link point, if so, execute the link point, and return to S0; otherwise, execute S4.

In this embodiment, the link point is executed, that is, the web page jumps, and the link point can be returned to S0 for the next cursor positioning operation after the link point is executed.

In this embodiment, S3 and S4 also include: setting the cursor positioning flag; S4' is specifically: judging whether the cursor positioning flag is set, if so, the cursor has positioned the link point, otherwise the cursor has not positioned the link point;

Specifically, in this embodiment, the implementation method of this embodiment is described in conjunction with specific example diagrams. With reference to FIG. 3 , in this embodiment, a thumbnail image of the webpage structure is generated by automatically identifying each main area of the browsing page. Among them, S101 is the browser page, and S102 is the generated thumbnail. This thumbnail can be called up by a shortcut key (such as a long press of the OK key), or by clicking S103 (call button) when using a touchpad remote control, etc. , the user selects the area in the thumbnail to move the cursor into the corresponding area on the browsing page. This can effectively reduce the actions required for the user to move the cursor to the target link.

Among them, the specific implementation scheme of S3 is shown in Fig. 4, with the current position of the cursor as the coordinate origin O, a coordinate system is generated, and the straight lines _L1 and _L2 are perpendicular to each other, forming angles of 45° and -45° with the x-axis respectively. L ₁ and L ₂ divide the main area where the cursor is located into four areas Q1, Q2, Q3, and Q4, which correspond to the right key, up key, left key, and down key in the direction keys, for example, Q1 corresponds to the right key, and Q2 corresponds to The up button, Q3 corresponds to the left button, and Q4 corresponds to the down button. When the user clicks the right button, up button, left button, and down button, all the link points scanned in Q1, Q2, Q3, and Q4 are used as judgment objects, that is, they are considered The target link point positioned by the user through the cursor is among these link points. For example, when the user clicks the right button, all link points (marked by dots) are scanned from the area Q ₁ shown in Figure 4, and the point a with the smallest angle with the x-axis and the point a with the origin O are found from all link points. The principle of selecting point a or point b as the target link point for the nearest point b is explained in conjunction with Figure 5;

Referring to Figure 5, the specific implementation process of S3 includes:

S3-1: Set the first scanning area according to the current cursor position, and scan all link points in the first scanning area according to the direction keys;

S3-2: Find the link point (a) with the current position of the cursor as the coordinate origin and the smallest angle with the x-axis and the link point (b) with the shortest distance from the coordinate origin; record the distance between the link point and the coordinate origin is S, and the angle between the link point and the x-axis is recorded as β;

In this embodiment, let the distance between point a and the origin be S _a , and the angle between point _a and the x-axis be β _a ; _b ;

S3-3: Determine whether the difference between S _a and S _b is less than the preset length, if yes, execute S3-5, otherwise execute S3-4;

S3-4: Determine whether the difference between β _b and β _a is greater than the preset angle, if yes, execute S3-5, otherwise execute S3-6;

S3-5: Position the cursor to the link point (a) with the smallest angle, execute the link point, and return to S0;

S3-6: Position the cursor to the link point (b) with the shortest distance, execute the link point, and return to S0.

In this embodiment, if S _a -S _b < preset length, that is, the difference between the distance between point a and the origin and the distance between point b and the origin is within the preset length, that is, the difference between point a and point b is not far away, then select a point; or, even if the difference between the distances between the two and the origin exceeds the preset length, but β _b -β _a > preset angle, that is, the angle between point a and the x-axis is much smaller than the angle between point b and the x-axis, still Select point a, where the specific values of the preset length and the preset angle need to be selected through testing during implementation. In other cases, select point b as the target link point, that is, if S _a -S _b ≥ preset length and β _b -β _a ≤ preset angle, then position the cursor to the link point (b) with the shortest distance.

Among them, the implementation process of S4 is shown in Figure 6, the user's current cursor position is taken as the origin O, when the user clicks the OK button, and the current cursor is not on any link, the link is scanned in the square area P in Figure 6 point (marked by a dot), where the distance S _c (dotted line in Figure 6) between point c and the origin is the smallest, then move the cursor above point c. Among them, the side length of the square needs to select the best value through testing during implementation.

In this embodiment, the program that implements the method of this embodiment can be set to work in the traditional remote control or the remote control software on the mobile phone. When the user opens the browser through the traditional remote control or mobile phone remote control software, it will automatically locate The link function is turned on immediately (i.e. execution of S0 starts). If the user clicks the call button or shortcut key (such as long press the OK button), each main area of the browsing page will be automatically identified and a thumbnail of the web page structure will be generated, and then the thumbnail of the main area of the browsing page will be called out, and the user chooses to enter The system moves the cursor to the subject area selected by the user. If the user uses the right button in the cursor positioning process, then according to the distribution of links in the _Q1 area as shown in Figure 4, the user's intention is judged, and then the cursor is positioned on the analyzed link point that meets the user's intention.

If the user manipulates the TV by means of touch remote control, screen transmission, motion recognition, etc., if the user clicks the S103 button shown in Figure 3, a thumbnail image of the web page will be called up for the user to click, and the cursor will be positioned on the main area selected by the user middle. If the user makes a click action (equivalent to pressing the OK key), scan all the links in the _P2 area shown in Figure 6, and position the cursor to point c with the smallest distance S _c from the origin.

The method of the embodiment of the present invention automatically positions the cursor. No matter what tool the user uses to control the TV, as long as the direction key and the determination key can be sent to the TV, the present invention can automatically move the cursor to the nearest link point that meets the user's intention. Such a method relaxes the requirements for the tools for controlling the TV, and the invention solves the problem of inaccurate positioning, realizes the simplification and humanization of the smart TV browser operation mode, and has broad application prospects and practical value.
