Background technique

With the development of mobile Internet technology, due to the portability of mobile terminals, people are more and more accustomed to using mobile terminals for web browsing and information interaction. When browsing web pages and/or interacting with information, it is usually necessary to use an input box displayed on a mobile terminal to input information.

In recent years, in order to facilitate user operations, touch screen technology has been gradually introduced into mobile terminals. When inputting an input box in a touch-screen mobile terminal, usually before information input, it is first necessary to locate an input box for inputting information. For the input in the input box, the browsers of most mainstream touch-screen mobile terminals do not have a good positioning function at present. In order to solve the above problems, Apple has proposed a Safari browser. In the Safari browser, the mixed positioning method of the input box and the drop-down selection box is used to quickly locate the page controls. Associate the input box control and the drop-down selection box control according to certain rules. During user operation, just click the shortcut button provided by Safari to immediately locate the next input box control or drop-down selection box control on the page. However, this positioning method of Safari can only distinguish the front and back relationship of the control, which means that Safari can only locate the front and back two page controls associated with the current control, and cannot accurately distinguish the directions of up, down, left, and right, resulting in low usability and limitations. Larger and other defects. In addition, in the current design of other browser products, when the input box is blocked by the keyboard or other interfaces, as shown in Figure 1, the keyboard needs to disappear before the input box covered by the keyboard can be selected.

Additionally, any aspect described herein may comprise at least one element of a claim.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 2 shows a flowchart of a method for locating an input box in a mobile terminal according to the present invention. Here, the mobile terminal is a touch screen mobile terminal.

When touching the display screen of the mobile terminal to perform text input in the input box, after the text input of the current input box has been completed, when it is necessary to go to another input box for text input, the input box positioning method of the present invention can be used. Rapid positioning.

As shown in FIG. 2 , first, in step S210 , a position point is selected from the current input box (ie, the currently focused input box, or also called the current focus input box) as a base point. The selected location point may be any point in the currently focused input box. For example, the position point can be selected as the base point by moving the cursor to a position point in the current input box for confirmation. Apparently, when the position point is selected, the mobile terminal can obtain the coordinate position of the cursor as the coordinate position of the selected base point. How the mobile terminal obtains the coordinate position of the cursor is well known in the art. In a preferred embodiment of the present invention, the base point may be the center point of the currently focused input box.

Then, in step S220, within the scope of the cross with the selected base point as the center, in the upward, downward, leftward and rightward extension directions of the cross, for each direction, In the input boxes whose glyphs intersect, search for the input box closest to the currently focused input box. Here, the cross-shaped range may be an X×Y cross-shaped range, for example, 200 pixels×150 pixels, or an X×X cross-shaped range, for example, 200 pixels×200 pixels. In addition, X and Y in the cross-shaped range can take different values as required, for example, different values can be selected according to the model of the mobile terminal (or the screen size of the mobile terminal). In addition, in the cross shape, the extension ranges in the left, right, up and down directions can have the same or different values. For example, in the above-mentioned cross shape of 200 pixels×200 pixels, the extension ranges in the left, right, upward and downward directions may all be 100 pixels. Alternatively, the extent to the left is 50 pixels, and the extent to the right is 150 pixels. The upward extension range takes a value of 100 pixels, and the downward extension range takes a value of 100 pixels. Specifically, when searching, for example, within a cross-shaped range of 200 pixels×200 pixels and the values of the extension ranges to the left, right, up and down are all the same, and the selected base point is the current input box A In the case of the center point, it is considered that the two sides centered on the center point of the current input box A are respectively 200 pixels in cross shape (that is, counting from the center along the upward, downward, leftward and rightward The input box intersected by any one of the two lines whose length is 100 pixels) is within the search range; otherwise, it is deemed not to be within the search range. FIG. 3 shows a schematic diagram of intersection of a cross shape centered on the center point of the input box and the input box. For each of the extending directions upward, downward, leftward, and rightward, whether there is an input box within the search range is searched. For example, when the cross intersects the input box in the direction extending to the right, it is considered that the input box is within the search range, and it corresponds to the right-moving indicator when positioning. Searches in other extension directions are also processed as above. When there are multiple input boxes within the search range, for example, if there are input boxes B, C, and D within the search range in the upward extension direction, where input box B is the closest to the current input box A, it will be the same as The input box B closest to the current input box A is used as the input box searched in the upward extension direction. For other directions, search the input box in the same way. Here, the distance from the current input box may, for example, refer to the distance between the searched input box and the nearest edge of the currently focused input box. Alternatively, the distance from the current input box may also be, for example, the distance between the center point of the searched input box and the base point. In a preferred embodiment, the two sides of the cross are respectively parallel to the edges of the mobile terminal. In an alternative embodiment, the two sides of the cross may not be parallel to the edge of the mobile terminal, but form a slightly smaller inclination angle with the edge of the mobile terminal.

After the above-mentioned search is completed for each extension direction of the cross, in step S230, the input box ID number of the searched input box is associated with the corresponding movement indication item used to indicate the movement direction of the input box and stored in the In the corresponding relationship table of the input box currently concerned, the moving indicator includes a left-moving indicator, a right-moving indicator, an up-moving indicator and/or a down-moving indicator. For example, if an input box is found on the left side, the input box ID of the input box is stored in the correspondence table of the current input box in association with the left-moving indication item. Similarly, if input boxes are searched in the directions of right, up and down, each input box is stored in the corresponding in the relationship table.

After the searched input box is associated with the corresponding movement indication item and stored in the correspondence table, in step S240, according to the movement indication item in the obtained correspondence table that has been associated with the input box ID, move Available positioning shortcut keys for the user to locate the input box are formed on the screen of the terminal, and the positioning shortcut keys include corresponding LEFT, RIGHT, UP, and/or DOWN keys. Here, the left item key indicates that the page moves (scrolls) quickly to the left input box, the right item key indicates that the page quickly moves (scrolls) to the right input box, and the upper item key indicates that the page quickly moves (scrolls) to the upper input box, and The next key indicates that the page moves quickly (scrolls) to the input box below.

Specifically, in an example, when an available positioning shortcut key that can be used by the user to locate the input box is formed on the screen of the mobile terminal according to the obtained movement indication item in the correspondence table that has been associated with the input box ID Firstly, according to the obtained correspondence table, only the positioning shortcut keys corresponding to the movement indication items associated with the input box IDs can be generated on the screen of the mobile terminal; then, all the generated positioning shortcut keys can be made available.

Or, in another example, when an available locating shortcut key that can be used by the user to locate the input box is formed on the screen of the mobile terminal according to the movement indication item in the obtained correspondence table that has been associated with the input box ID , when the input box is input, a positioning shortcut key group can be generated on the screen of the mobile terminal, and the positioning shortcut keys include a left key, a right key, an upper key and a lower key, and at this time, the positioning shortcut keys All navigation shortcuts are disabled. Then, after obtaining the correspondence table of the current input box, according to the obtained correspondence table, the positioning shortcut keys corresponding to the movement instruction items associated with the input box ID in the generated positioning shortcut key group become available . Fig. 3B shows a schematic diagram of the above situation.

After the positioning shortcut keys that can be used to locate the input box are formed, in step S250, the positioning shortcut key corresponding to the desired input box is selected from the formed available positioning shortcut keys. Then, in step S260, the selected locating shortcut key is activated to locate a desired input box based on the input box ID associated with the shortcut key. For example, click or otherwise touch the selected locating shortcut key to quickly locate the desired input box using the input box ID associated with the shortcut key.
