Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one

This embodiment provides a display adjustment method, as shown in Figure 1, including:

Step 101. Determine the user's content attention area on the terminal display interface according to the user's touch operation.

During use, there are the following scenarios: the user is browsing a news website, and there is spam content in the webpage, such as: FLASH advertisement, picture advertisement, repeated title links, etc. The information that the user wants to obtain is news reports, so the user only wants to enlarge the content of the main text of the web page. At this time, the user may slide a finger on the screen corresponding to the content of the webpage text, so as to determine the content attention area, and the display content included in the content attention area is the display content to be enlarged.

Step 102, generating a content zoom-in area corresponding to the content attention area, and the layer where the content zoom-in area is located is above the layer where the content attention area is located.

In order to make the display ratios of the content magnification area and the content focus area independent of each other, a new layer for placing the content magnification area is created above the layer where the content focus area is located. The content displayed in the content magnification area is consistent with the display content included in the content attention area, ensuring that the content magnification area achieves the enlarged display of the content attention area.

Step 103, enlarge and display the display content included in the content focus area in the content enlargement area.

Although the content displayed in the content magnification area is consistent with the display content contained in the content attention area, the zoom effect can only be achieved after the content attention area is enlarged. For example: the content attention area contains a piece of text with a text size of 4 small, and the text size is displayed in the content zoom-in area with a text size of 2 small.

The display adjustment method provided in this embodiment can determine the content attention area according to the sliding track, establish a content zoom-in area in another layer above the layer where the content attention area is located, and zoom in and display the display content contained in the content attention area . In the prior art, the entire page is enlarged, and the enlarged page cannot be completely displayed in the display area, and the entire content of the enlarged webpage needs to be dragged several times to browse, which is inconvenient to operate. In the present invention, the content magnification area can enlarge the content attention area in the display area, and the other areas of the display area except the content attention area maintain the original display, and the display content will not overflow the display area due to the enlargement, thereby simplifying the user operation. Improve browsing efficiency.

Further, step 101 includes:

The content focus area is determined according to the start coordinates and end coordinates of the sliding track of the user's touch operation, wherein the slide track is used to describe the scope of the content focus area.

The starting coordinate and the ending coordinate may be used as two endpoints of a diagonal line of a rectangle to further determine the content attention area. As shown in FIG. 2 , the starting point of the sliding track is point A, and the ending point is point C. According to the coordinates of the two points AC, a rectangle ABCD can be determined, which is the content attention area. Similarly, the content focus area can also be determined according to the coordinates of point B and point D. In addition, the length of the content attention area can be determined first according to point A and point D, and then the width of the content attention area can be determined according to point D and point C. The sliding track may also be split, and a content attention area in the shape of a polygon or an arc is determined according to the divided sub-sliding tracks.

It should be noted that the above start coordinates and end coordinates may be coordinates on the display device (if the pixel coordinates of the screen), that is, relative coordinates, or absolute coordinates within the page. When the coordinates are relative, the display content contained in the content attention area will change with the sliding of other areas in the display area. When the coordinates are absolute, the corresponding relationship between the display content contained in the content focus area and the display content in the page is fixed, and will not change due to sliding of other areas in the display area. As for other areas of the display area, as shown in FIG. 3 , the display area is an area that can be displayed by the electronic device, and other areas are areas in the display area other than the content attention area.

Further, as shown in Figure 4, step 101 also includes:

Step 401. Receive a user-triggered instruction to move a content attention area.

When the user drags the border of the content focus area, a movement indication of the content focus area is triggered. In addition, when the user presses and holds an area inside the frame of the content attention area and drags the content attention area through this area to move, the indication of moving the content attention area may be triggered.

Step 402: Determine the moved position of the content attention area according to the movement indication of the content attention area.

The movement instruction received in step 401 includes the offset of the movement of the content focus area, and the moved position of the content focus area can be calculated according to the offset.

Step 103 includes:

Step 403, zooming in on the display content included in the content focus area after the shifted display position in the zoom-in area.

After the content focus area is moved, the displayed content contained therein will also change accordingly. Since the content magnification area corresponds to the content attention area, the content magnification area enlarges the display content included in the content attention area after the shifted display position. At this time, the display position of the content magnification area on the terminal screen may be fixed, and by acquiring the user's touch operation on the terminal display content, the content within a preset range around the touch point is displayed in the content magnification area. The content displayed in the content magnification area can be changed and displayed according to the position of the touch point generated by the user's touch operation, so that it is convenient for the user to operate with one hand.

It should be noted that, in addition to the fact that the content focus area can be moved, the enlarged area can also be moved according to a movement instruction triggered by the user. The user can trigger the moving indication of the enlarged area by dragging the border of the enlarged area, or long press and drag the area inside the border of the enlarged area to trigger the moving indication of the enlarged area. After receiving the instruction to move the enlarged area, the enlarged area can be moved only according to the instruction to move the large area, and the position of the content attention area remains unchanged, so that the user can browse the content in the layer where the enlarged area blocked by the enlarged area is located. It is also possible to correspondingly change the position of the content attention area while moving the zoomed-in area, so as to realize an effect similar to a magnifying glass: wherever the zoomed-in area moves, the area corresponding to the zoomed-in area is enlarged. The correspondence may be the area covered by the enlarged area, or the unoccluded area of the enlarged area.

In the process of practice, the inventor also found that when the right side of the enlarged area coincides with the right edge of the display area, there is a distance between the determined right edge of the content attention area and the right edge of the display area. When moving the magnified area, the center point of the magnified area is often used as the basic coordinates for determining the content attention area, so that when the magnified area is moved, the area at the edge of the display area cannot be enlarged. In order to solve this problem, it is determined whether to move the content attention area according to the triggering situation of the movement indication of the enlarged area. For example: when the user drags the magnified area through the right border of the magnified area, the current content attention area is moved horizontally to the right border of the display area, and the moved content attention area is enlarged and displayed. It is also possible to move the content attention area horizontally to the right side of the display area when it is detected that the right edge of the enlarged area coincides with the right edge of the display area, so that the right edge of the content attention area coincides with the right edge of the display area and the display area to zoom in on the moved content focus area.

Further, step 102 includes:

determining the length and width of the content magnification area according to the length and width of the content attention area and a preset ratio value, and generating the magnification area according to the length and width of the content magnification area;

Alternatively, the enlarged region is generated according to a preset length and width.

The preset ratio value is equivalent to the magnification multiple, and the preset ratio value can be set by the user or can be a default value of the system. If the display content included in the content focus area is doubled, the length and width occupied by the enlarged display content will also be doubled. When generating the magnified region according to the preset length and width, the magnified region with the preset length and width may be generated at a preset position on the screen. The magnification factor of the magnified area generated according to the preset length and width has nothing to do with the length and width of the magnified area. If the enlarged display content cannot fill the entire enlarged area, there will be a blank part in the enlarged area. If the magnified area cannot display all the magnified display content, the user can perform operations in the magnified area, including browsing and content editing through gesture operations.

A usage scenario of the embodiment of the present invention is provided below: the user is browsing news on the mobile phone, and at this time, the news page is opened, and the user operates on the screen according to the sliding track from the upper left to the lower right, and the screen shows that the sliding track circles news content (for example: "March 19, 2013" in 14-point font size) and above the news content, the circled news content after enlargement is displayed through a display area with a border (for example: 26-point font size "March 19, 2013"). When the user needs to cancel the magnified display, the operation is performed in the magnified area according to the sliding track from the upper left to the lower right. At this time, the display of the magnified area is canceled and the space occupied by the magnified area is released.

The display adjustment method provided in this embodiment can determine the content attention area according to the sliding track of the user's touch operation, establish a content zoom-in area in another layer above the layer where the content attention area is located, and display the content included in the content attention area The content is displayed enlarged. In the prior art, the entire page is enlarged, and the enlarged page cannot be completely displayed in the display area. As shown in Figure 5, the content attention area 1 and the content attention area 2 that the user wants to browse cannot be displayed in the same display area , after browsing the enlarged content attention area 1, the user needs to drag the screen several times to browse the enlarged related area 2, which is inconvenient to operate. In the present invention, the enlarged area can enlarge the content attention area in the display area, and the other areas of the display area except the content attention area maintain the original display, and there will be no problem that the displayed content overflows the display area due to the enlargement, thereby simplifying user operations , improve browsing efficiency. In addition, this embodiment can determine the content attention area according to the start coordinates and end coordinates of the sliding track of the user's touch operation. The user can determine the content attention area and browse the enlarged display contained in the content attention area through a simple sliding operation. content. The user can drag the content focus area and zoom-in area to browse. When the zoom-in area covers other contents of the layer where the current content focus area is located, the zoom-in area can be moved to other positions in the display area, so that the user does not need to confirm the content multiple times Focus on the area and reduce the user's repeated operations.
