Detailed Description
In the following detailed description of the preferred embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, specific features of the invention, such that the advantages and features of the invention may be more readily understood and appreciated. The following description is an embodiment of the claimed invention, and other embodiments related to the claims not specifically described also fall within the scope of the claims.
Fig. 1 shows a schematic view of a device for handling page turning.
As shown in fig. 1, an apparatus for processing page turning includes afirst device 1, configured to determine a page turning boundary according to a page turning motion; thesecond device 2 is used for acquiring partial pages in display areas on two sides of the page turning boundary; third means 3 for stitching said partial pages to form a display page.
The device for processing page turning can be connected with a display screen of the electronic device, and human-computer interaction with a user is realized through the display screen. The page turning process of the electronic document by the user is generally a process of turning a page of an upper page and displaying a lower page on a display screen.
In the invention, firstly, thefirst device 1 senses the page turning action of a user, including a page turning starting point, a page turning direction, a page turning speed and the like, and also senses the display boundary of a display screen. And then determining a page turning boundary according to the page turning action, for example, determining the page turning boundary along a page turning starting point, and determining the page turning boundary as a straight line or a curve passing through the page turning starting point. Then thesecond device 2 cuts the lower page along the page turning boundary, and the portion surrounded by the page turning interface and the display boundary in the direction away from the page turning direction is reserved as a portion of the display page, meanwhile, thesecond device 2 cuts the upper page along the page turning boundary, and the portion surrounded by the page turning interface and the display boundary in the page turning direction is reserved as another portion of the display page, and finally, thethird device 3 splices the two portions into the display page, and the boundary of the display page is formed by the display boundary.
Thefifth device 5 in the following text will directly render the display page to form uniform background color and text. In the rendering process, the part of the upper-layer page, which covers the lower-layer page in the display boundary, is not required to be rendered, and the rendering in the whole display interface can be completed through one-time rendering without separate rendering.
FIG. 2 illustrates an embodiment of turning pages.
Thefirst device 1 senses a page turning action of a user on a screen of the electronic device, such as a touch screen, a gesture and the like, and determines a page turning starting point according to the page turning action of the user.
In fig. 2, taking a finger touch screen as an example, the left diagram shows a touch screen position and a sliding direction, where the point S is a starting point of page turning. The middle and right diagrams of fig. 2 show schematic views of page turning boundaries in the emulation page turning and overlay page turning modes, respectively. When the user touches the screen and slides to one side, thefirst device 1 first determines the user's motion. When thefirst device 1 determines the user's motion as a valid motion for turning a page, the position where the user touches the screen may be used as a starting point for turning a page. As a variation, the user touch screen position may also be used as a reference point, and the page turning starting point may be determined based on the reference point. Thefirst device 1 may select a direction of the touch screen sliding as a page turning direction, as a variation, or may modify the direction to a default page turning direction stored in the system according to the direction of the touch screen sliding. The process of determining that the motion of the user is a valid motion of page turning may be a preset threshold of motion amplitude, and when the travel distance of the touch screen motion is greater than a certain threshold, the motion is determined to be the valid motion of page turning, otherwise, the motion is determined to be an invalid motion.
The display boundary refers to the outer periphery of a page that can be displayed on the screen, and usually coincides with the boundary of the screen, or may be a partial window within the screen.
According to another embodiment of the present invention, when pages are turned by using gestures, voice, and the like, the center of the screen of the electronic device may be set as a page turning starting point, or other points such as the lower right corner, the upper right corner, the lower left corner, the upper left corner, and the like in the screen may be selected and set as a page turning starting point as needed, and the page turning direction may be preset according to the typesetting of the electronic document, the usage habits of the user, and the like. For example, the layout of the electronic document is vertical, and the electronic document is aligned up, and the page may be turned from bottom to top by default.
In the present invention, the page turning direction may be preset to any angle of 360 degrees on the screen of the electronic device with the page turning starting point as a starting point, for example, as shown in fig. 2. Thefirst device 1 may sense the layout of the text to limit a specific angle, such as left, right, upward and other specific angles, or may select the specific angle by the user, and parameters such as the direction of page turning are stored in theeighth device 8, and when thefirst device 1 senses the motion of the user, the motion determination of the user and the setting of the direction of page turning are calculated, so as to determine the direction of page turning of the page, for example, as shown in the right diagram in fig. 2.
The process of determining the effective action may also adopt other determination methods mentioned in the prior art, and the present invention is not described in detail.
Fig. 3 shows a schematic view of a fourth arrangement.
As shown in fig. 3, the apparatus further includes afourth device 4, configured to determine the page turning boundary as a straight line or a curved line passing through the page turning starting point. In one embodiment of the present invention, the page turning boundary is mainly determined by two parameters, i.e., a page turning starting point and a page turning direction, and the page turning boundary is defined as a straight line or a curve passing through the page turning starting point. For example, when the page turning mode is the overlay page turning, the page turning boundary may be defined as a straight line; when the page turning mode is simulation page turning, the page turning boundary can be defined as an arc line; the page turning boundary may be defined as an S-shaped curve, an irregular curve, or other shapes in the page turning mode or other page turning modes.
FIG. 4 shows a schematic diagram of a curved page turn boundary.
Thefourth device 4 is connected to thefirst device 1, and is configured to define a straight line passing through a page turning starting point in a page turning direction, and divide the screen into an upper half and a lower half, as shown in a left diagram in fig. 4, where a line drawn from the page turning starting point to the upper half randomly intersects with a display boundary of the screen; meanwhile, as shown in the middle graph in fig. 4, a line drawn out randomly from the page turning starting point to the lower half part intersects with the display boundary of the screen; as shown in the right diagram of fig. 4, one line is randomly selected from the lines in the upper half and the lines in the lower half, respectively, so as to form a complete page turning boundary.
The mode of randomly forming the page turning boundary in the invention enables a user to have richer user experience when using the invention.
The page turning boundary may be formed by using the existing scheme, for example, the scheme described in patent CN102221980B, and the present invention is not described in detail.
FIG. 5 shows a schematic diagram of a process for cutting a sheet.
As shown in fig. 5, in the present embodiment, a left slide is taken to take a covering page turning as an example, the left diagram in fig. 5 shows a schematic top view when a page is turned to the left, wherein an inside of a frame surrounded by a black thick frame line is divided into a display area defined by a display boundary, and the right diagram is a schematic diagram of a cutting process, thesecond device 2 cuts a lower page L along the page turning boundary, and a portion surrounded by the page turning interface and the display boundary in a direction away from the page turning direction is reserved as a first page, meanwhile, thesecond device 2 cuts an upper page T along the page turning boundary, and a portion surrounded by the page turning interface and the display boundary in the page turning direction is reserved as a second page, and finally, thethird device 3 splices the first page and the second page into a display page, and a boundary of the display page is formed by the display boundary.
When thefifth device 5 renders the display page subsequently, it avoids rendering the upper page and the lower page separately, and also reduces rendering of the portion of the lower page that is covered by the upper page, that is, the portion of the lower page L that is covered by the grid portion in fig. 5.
Fig. 6 shows a schematic view of a fifth and a sixth arrangement.
As shown in fig. 6, the apparatus further includes afifth device 5 and a sixth device 6, where thefifth device 5 is used for rendering the display page; the sixth device 6 is used for controlling thefirst device 1, thesecond device 2, thethird device 3 and thefifth device 5 to operate until no page turning action is detected.
The sixth device 6 is connected to each of the other devices, and controls the other devices to operate in a predetermined logic. The fifth means 5 renders the background color and the text to make the page appear on the screen.
The sixth device 6 is respectively connected with thefirst device 1, thesecond device 2, thethird device 3 and thefifth device 5, and logically ensures the normal operation of the equipment.
Fig. 7 shows a schematic view of a seventh arrangement.
As shown in fig. 7, the apparatus further includes aseventh means 7, where theseventh means 7 is configured to render the page turning boundary such that the page turning boundary has at least one of a bright-dark distinction effect, a stereoscopic effect, and a bending deformation effect.
The seventh means 7 may be independent from thefifth means 5 or may be a part of thefifth means 5, thefifth means 5 mainly functions to render the display page, and theseventh means 7 mainly renders the page turning boundary. Because the rendering objects are different and the calculation modes required to be adopted are different, the rendering objects and the calculation modes are separately arranged, so that the page rendering and the page turning boundary rendering can be separately calculated, the calculation target can be achieved by adopting a simpler algorithm to execute, the complex calculation is reduced, and the occupation of resources is reduced.
