Fig. 1 is a flowchart illustrating a gesture zoom control method of a touch-enabled device according to an embodiment of the present invention. The gesture zooming control method of the touch-controllable device is particularly applied to the touch-controllable device, wherein the touch-controllable device can perform human-computer interaction with a user and has a touch-control function, and the touch-controllable device comprises but is not limited to a touch-controllable mobile phone, a touch-controllable tablet and a touch-controllable all-in-one machine. As shown in fig. 1, the gesture zoom control method of the touch-controllable device includes the following steps:
s10: a target element on a display page is determined.
It is understood that the touchable device performs a page display through the touchable screen, and the displayed page is referred to as a display page. The display page has one or more elements, such as fonts, images, and controls (e.g., buttons, check boxes, and progress bars) on the page.
In one embodiment, before performing the gesture zoom operation, an element to be zoomed, that is, the target element, needs to be determined. Specifically, the target element may be determined by a user's selection operation (a closed area formed by connecting touch tracks) on the touch screen, where the selection operation may be performed multiple times. Further, when determining the target element on the display page, the target element may be determined by means of voice control, eye tracking, and the like, in addition to the manner of receiving the touch information, which is not limited herein.
S20: zooming out or zooming in the target element according to the gesture on the display page.
In one embodiment, the touchable device will zoom in, zoom out, or zoom in on the target element according to the gesture on the displayed page. Specifically, the zooming out or zooming in may be determined by information related to the zooming operation input by the user, and the touchable device executes a corresponding target element zooming out instruction or a target element zooming in instruction according to the information related to the zooming operation to zoom in or zoom out the target element.
Further, in step S20, zooming in or zooming out the target element according to the gesture on the display page specifically includes:
and zooming the target element according to the received gesture zooming operation information.
The gesture zooming operation information is operation information received by the touch device when the user performs the gesture zooming operation, such as zooming size, zooming speed, initial zooming coordinates, ending zooming coordinates and the like. The gesture zooming operation information is related to the target element and is used for zooming the target element.
In an embodiment, a user receives gesture zoom operation information through a touch screen, and generates a corresponding target element zoom-out instruction or a target element zoom-in instruction according to the gesture zoom operation information, so as to perform zoom operation on a target element. The touch-controlled equipment receives gesture zooming operation information through the touch-controlled screen, and zooming results of the target elements are displayed on the touch-controlled screen according to the gesture zooming operation information.
S30: the state of the target element is determined during the reduction or enlargement of the target element or at the end of the reduction or enlargement of the target element.
Wherein the state of the target element includes a normal zoom state and a boundary state. When the target element is in a normal zooming state, the target element is zoomed normally, and when the target element is in a boundary state or reaches the boundary state, corresponding boundary operation is triggered according to the boundary state. It can be understood that, during the process of zooming the target element or at the end of zooming, if the judgment condition of the boundary state is satisfied, the target element is considered to reach the boundary state, at this time, after the target element reaches the boundary state, a corresponding boundary operation will be triggered according to the boundary state, where the judgment condition of satisfying the boundary state will be described in the following embodiments.
In one embodiment, during the process of zooming by the user using the gesture, the touchable device will synchronously display the zooming result on the touchable screen, and at this time, there may be two stages for determining the current state of the target element. One is to judge the state of the target element during the zooming process of the target element, and this judgment can synchronously judge the state of the target element when the target element is zoomed; the other is to judge the state of the target element only when the target element finishes zooming, that is, the user's finger leaves the touch-sensitive screen. The two modes have advantages respectively, and can be flexibly configured according to specific scenes.
Further, in step S30, during the reduction or enlargement of the target element, or at the end of the reduction or enlargement of the target element, determining the state of the target element includes:
when the target element is subjected to the zooming operation, or after the target element is subjected to the zooming operation, whether the target element reaches the boundary state is judged.
It will be appreciated that the purpose of determining the state of the target element in this implementation is to determine whether the target element has reached a boundary state. In an embodiment, the touch-controllable device executes a corresponding zooming operation according to gesture zooming operation information received in real time, and if it is preset by a user that the state of a current target element is determined in real time in the zooming process of the touch-controllable device, when the touch-controllable device executes the zooming operation, whether the target element reaches a boundary state is judged in real time; if the user presets that the state of the target element at the end time is determined when the zooming operation of the touch-controllable device is finished, after the zooming operation of the touch-controllable device is finished, whether the target element reaches the boundary state or not is judged at the end time. In the implementation, whether the target element reaches the boundary state can be judged quickly and accurately according to the executed zooming operation.
S40: and when the state of the target element reaches the boundary state, triggering boundary operation according to the boundary state.
Wherein, the boundary operation refers to an operation performed when the target element reaches a boundary state.
In one embodiment, when the target element reaches the boundary state, the boundary operation corresponding to the boundary state is triggered, wherein the boundary state may be one or more, and the boundary operations corresponding to different types of boundary states may be different.
Further, the boundary state includes a boundary reduction state and/or a boundary enlargement state. In one embodiment, the target element may have a boundary state when zoomed out, and may also have a boundary state when zoomed in. It can be understood that there is often no limitation when performing a zoom operation on a target element in an actual scene, and when the target element is zoomed to a smaller resolution, there is no actual effect, and for a case where the target element is a picture, a user cannot obtain effective information on the picture with the smaller resolution, and for a case where the target element is a control, the user cannot perform an accurate operation on the control with the smaller resolution; there is also no practical effect when the target element is enlarged to a larger resolution. In addition, when the target element is in a smaller or larger zoom size, it is troublesome to restore the target element to a normal zoom size, and other operations performed by the user may be affected. In this embodiment, the practicality of scaling the target element can be improved and the operation efficiency can be improved by setting the boundary reduction state and/or the boundary enlargement state.
Further, in step S10, determining a target element on the display page specifically includes:
and if the selected elements exist on the display page, taking the selected elements as target elements.
And if the selected elements do not exist on the display page, taking the elements on the display page as target elements.
It will be appreciated that if the user does not pre-select an element, the user will directly zoom all elements on the displayed page when performing the zoom operation. Specifically, when the user operates all elements on the display page, the zoom operation may be directly performed on all elements, and when zooming to the boundary reduction state, all elements on the display page may be cleared through an element deletion operation (one type of boundary operation); when the user only operates partial elements, the elements can be selected in advance and then gesture zooming is carried out. The method for determining the target elements on the display page in the embodiment can improve the practicability, operability and operation efficiency.
Further, in step S30, determining the state of the target element specifically includes:
s311: and determining the state of the target element according to the area of the target element, wherein when the area of the target element is smaller than or equal to a first preset value, the state of the target element is determined to reach a boundary reduction state.
S312: and when the area of the target element is larger than or equal to a second preset value, determining that the state of the target element reaches a boundary amplification state.
Wherein the first preset value is smaller than the second preset value.
In one embodiment, the state of the target element is determined using the area of the target element to determine whether the target element reaches the boundary state. The first preset value in this embodiment may specifically be a resolution of 20 × 20 (the resolution is a pixel area of a screen, and the area of the target element refers to the pixel area), and the second preset value may specifically be 2048 × 1536. It is understood that when the target element reaches the boundary reduction state at the time of zooming, the target element has a resolution of only 20 × 20 at this time, and is almost unclear. Assuming that the screen resolution of the touchable device is 1024 × 768, when the target element reaches the boundary zoom-in state at the time when the resolution of the target element is 2048 × 1536, the target element is likely to be out of the screen at the time. In this embodiment, by setting the first preset value and the second preset value, the scaling of the target element can be flexibly adjusted in the touch-controllable devices with different resolutions, so that the display size of the target element in the touch-controllable devices with different resolutions is more reasonable.
Further, in step S30, determining the state of the target element further includes:
s321: and determining the state of the target element according to the area change ratio of the target element, wherein the area change ratio of the target element is the ratio of the current area of the target element to the original area of the target element, and when the area change ratio of the target element is smaller than or equal to a first preset ratio, determining that the state of the target element reaches a boundary reduction state.
The current area of the target element refers to the area size of the target element at the current moment. The original area of the target element refers to the area size of the target element corresponding to the time when the scaling is started.
S322: and when the area change ratio of the target element is greater than or equal to a second preset ratio, determining that the state of the target element reaches a boundary amplification state.
Wherein the first preset ratio is smaller than the second preset ratio.
In an embodiment, the boundary state may be determined by an area change ratio of the target element, where the area change ratio of the target element is a ratio obtained by dividing a current area of the target element by an original area of the target element.
The difference between the area change ratio of the target element and the area of the target element is that the screen resolutions of different touch devices may be different, and if the boundary state is determined by using the area of the fixed target element, the boundary state is not necessarily applicable to all touch devices. Specifically, if the boundary determination is determined after the user stops zooming, when the area of the target element is 10% of the original area of the target element, the target element may be considered to be unclear, and at this time, a boundary reduction state is reached; when the area of the target element is 400% of the original area of the target element, the target element may be considered to be out of the screen, and the boundary enlargement state is reached. The area change ratio of the target element in this embodiment can be adjusted through configuration, and the requirements of different users can be met.
Further, in step S30, determining the state of the target element further includes:
s331: and determining the state of the target element according to the average distance between the touch points of the contact of the finger and the touch screen, wherein when the average distance between the touch points of the contact of the finger and the touch screen is less than or equal to a third preset value, the state of the target element is determined to reach a boundary reduction state.
S332: and when the average distance between the touch points of the contact of the finger and the touch screen is larger than or equal to a fourth preset numerical value, determining that the state of the target element reaches a boundary amplification state.
Wherein the third predetermined value is less than the fourth predetermined value.
In an embodiment, a specific implementation of determining the state of the target element and determining whether the target element reaches the boundary state is further provided. In this embodiment, the boundary state is determined by the average distance between the touch points where the user's fingers contact the touch screen, and it can be understood that the distance between the touch points may reflect the zoom degree of the target element when the user zooms in a gesture. The average distance between the touch points refers to an average distance obtained by connecting lines between each finger (corresponding to each touch point) for controlling zooming, and dividing the sum of the distances of the lines by the number of the lines. Specifically, referring to FIG. 2, FIG. 2 shows a distance representation between touch points (black points in FIG. 2) when multi-finger (three fingers for example) is used to control zoom, and then the average distance between touch points in FIG. 2 can be taken as (L) 1 +L 2 +L 3 ) And/3 obtaining.
Further, in step S30, determining the state of the target element further includes:
s341: determining the state of the target element according to the change ratio of the average distance between the touch points contacted by the finger and the touch screen, wherein the change ratio of the average distance between the touch points contacted by the finger and the touch screen is the ratio of the average distance between the current touch points and the average distance between the original touch points, and when the change ratio of the average distance between the touch points contacted by the finger and the touch screen is smaller than or equal to a third preset ratio, determining that the state of the target element reaches a boundary reduction state.
The average distance between the current touch points refers to the average distance between the touch points of the touch points at the current moment. The average distance between the original touch points is the average distance between the touch points corresponding to the target element at the moment of starting to zoom.
S342: and when the variation ratio of the average distance between the touch points of the finger and the touch screen is greater than or equal to a fourth preset ratio, determining that the state of the target element reaches a boundary amplification state.
And the third preset ratio is smaller than the fourth preset ratio.
In one embodiment, since different devices have different screen sizes and screen resolution sizes, whether the target element reaches the boundary state can be determined by a variation ratio of an average distance between touch points where a finger contacts the touch screen. Specifically, if the boundary determination is determined after the user stops zooming, when the variation ratio of the average distance between the touch points is 10%, it may be considered that the target element is not clearly seen, and at this time, the boundary reduction state is reached; when the variation ratio of the average distance between the touch points is 200%, it can be considered that the target element is out of the screen, and the boundary enlargement state is reached. The boundary state is judged by adopting the change ratio of the average distance between the touch points, and the boundary state can be adjusted through configuration, so that the requirements of different users can be met, and the method can be applied to touch equipment with different screen sizes and screen resolution ratios.
Further, the boundary operations include element deletion operations and/or element copy operations.
Further, besides the element deleting operation and the element copying operation, the boundary operation may also include other types of operations, and the boundary operation may be changed accordingly according to the requirements of different scenarios, so as to achieve different trigger effects.
In particular, the boundary operation may also be a cut operation, performing a cut of the target element. The user can paste the cut target elements to the current page or the new page by adopting a paste operation, or can execute a cut operation and uniformly store the cut target elements in the clipboard. The user can find the clipped target element from the clipping plate at any time; the border operation may also be a close document operation, and when the user zooms out a target element on the interface to reach a zoom-out border state, the touchable device will close the current document. For example, when a user adopts documents such as text documents, presentation documents, table documents and the like, the effect of quickly closing the documents can be realized; the boundary operation can also be screen projection operation, when the target element is zoomed to reach an enlarged boundary state, the target element is projected on the display device which is connected with the touch device in advance, the target element is displayed by adopting a preset display ratio, and the function of quickly projecting the screen can be realized.
Further, in step S40, when the state of the target element reaches the boundary state, triggering a boundary operation according to the boundary state specifically includes:
when the target element reaches the boundary reduction state, triggering element deletion operation according to the boundary reduction state; and/or when the target element reaches the boundary amplification state, triggering element copying operation according to the boundary amplification state, and copying the target element to a page with a preset jump relation, wherein the page comprises a newly-built page.
In one embodiment, different boundary operations may be triggered accordingly depending on the particular boundary state (boundary reduction state or boundary enlargement state) reached by the target element. When the boundary reduction state is reached, element deletion operation can be triggered to delete the target element; when the boundary magnification state is reached, an element copy operation may be triggered, which will copy the target element onto other pages. The page has a preset jump relationship, and the jump relationship is used for determining a copy path of the target element. In particular, the page may be a new page. It can be understood that when the element deletion operation is triggered, the element may be deleted directly, or an inquiry box for whether to execute the deletion operation may be displayed on the display interface before the deletion operation is executed, and after the user clicks to determine the execution, the deletion operation is executed; similarly, when the copy operation is triggered, the element may be directly copied, or an inquiry box for whether to execute the copy operation may be displayed on the display interface before the copy operation is executed, and after the user clicks to determine the execution, the copy operation is executed. Further, in addition to popping up the query box before the boundary operation is performed, the selection options may be displayed on the display interface before the boundary operation is performed. For example, when a copy operation is triggered, selection options are displayed on the display interface, wherein the selection options comprise 'copy element to new page' and 'copy element to 8230', 'two options, and if a user selects' copy element to 8230 ',' the selection option, the currently opened document name will continue to pop up on the display interface, and the user can select the document name (one or more are supported) to copy the target element to the document. Further, after the option is selected, a query box for whether to execute the deletion operation may be displayed on the display interface, so as to improve the accuracy of the user selection.
It will be appreciated that in triggering an element boundary operation, a number of different function blocks (query block, selection block, etc.) may be set before the touchable device performs the boundary operation, and the boundary operation is performed when the user completes all function blocks. Of course, it is also possible that no function block is set before the boundary operation, and after the element boundary operation is triggered, the corresponding boundary operation will be directly executed.
Further, in addition to the element deleting operation and/or the element copying operation, other boundary operations may be performed, such as a boundary operation of cutting, hiding a target element, closing a current page, and jumping to a new page. It will be appreciated that multiple (non-conflicting) boundary operations may be performed simultaneously when the target element reaches the boundary state.
Furthermore, the gesture zooming control method of the touch-control device can be particularly applied to the intelligent interaction tablet. And the intelligent interaction tablet realizes the control of element scaling according to the gesture scaling operation of the user on the tablet touch screen. Specifically, when the area of the target element is taken as a judgment condition by the intelligent interactive tablet, zooming the target element according to the received gesture zooming operation information, and judging whether the area of the target element reaches a boundary zooming-in state or a boundary zooming-out state in the zooming process of the target element or when the zooming of the target element is finished. Similarly, when the area change ratio of the target element, the average distance between the touch points in contact with the touch screen of the tablet or the change ratio of the average distance between the touch points in contact with the touch screen of the tablet is taken as the judgment condition, the target element is zoomed according to the gesture zooming operation information received by the touch screen, and whether the target element reaches the boundary zooming-in state or the boundary zooming-out state is judged in the process of zooming the target element or when the target element finishes zooming. In an embodiment, a user can perform zoom control on a target element on a smart interactive tablet display page, and when the target element reaches a boundary enlarging state or a boundary reducing state, a boundary operation is triggered. Specifically, when the target element reaches the boundary reduction state, element deletion operation is triggered, and the target element is deleted from the display page; and when the element reaches the boundary amplification state, triggering element copying or cutting operation, and copying or cutting the target element into a new page or an opened page of the intelligent interactive tablet. The embodiment of the invention can obviously improve the operability and the operation efficiency of the intelligent interactive tablet during gesture zooming control.
In an embodiment, the implementation process of the present invention may specifically be: a user circles and selects a target element on a display page on a touch screen of the touch equipment through circle selection operation; and zooming the target element by the user through gesture zooming operation. If the boundary operation trigger preset by the touchable device is realized in the process of zooming the target element, when the target element zoomed by the user reaches a boundary zooming-out state or a boundary zooming-in state, executing corresponding operation according to the boundary zooming-out state or the boundary zooming-in state; if the boundary operation trigger preset by the touchable device is realized when the zooming of the target element is finished, when the zooming gesture zooming operation is stopped by the user, if the target element reaches a boundary reduction state or a boundary enlargement state, executing corresponding operation according to the boundary reduction state or the boundary enlargement state.
In the embodiment of the invention, the boundary state of the target element in the zooming process is judged, when the target element reaches the boundary state, the boundary operation can be triggered according to the boundary state, and the problem that the target element is reduced to be extremely small or the target element is enlarged to be completely beyond the screen range when the target element on the touch equipment is zoomed in the prior art can be solved. The method can effectively limit the scaling limit of the target element, trigger boundary operation in the boundary state, further process the target element and improve the operability and the operation efficiency in the actual scene application.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
