Detailed Description
The embodiment of the invention discloses an operation method of touch screen equipment and the touch screen equipment, which are used for reducing time delay of graphic display.
In order to better understand the touch screen device and the operation method thereof disclosed by the embodiment of the invention, an application scenario used by the embodiment of the invention is described below. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a graphical display when a touch screen device is operated by sliding or dragging according to an embodiment of the present invention. As shown in fig. 1, when a user operates a touch screen device by sliding or dragging, the coordinates need to be reported through a touch screen, the system software calculates a position according to the coordinates, lays out an interface according to the calculated position, draws a graph according to the laid-out interface, displays the drawn graph through a display screen, and the like, and then the drawn graph can be finally displayed to the front of the user. The touch screen and the display screen are both hardware in the touch screen device; calculating a position according to the coordinates, laying out an interface according to the calculated position, and drawing a graphic according to the laid out interface are implemented by software on the touch screen device. Therefore, the time for displaying the graphic can be shortened by software optimization, that is, the processing time for calculating the position from the coordinates, laying out the interface in accordance with the calculated position, and drawing the graphic in accordance with the laid out interface can be shortened. However, although the above method can shorten the processing period of the whole process, the movement of the interface always lags behind the movement of the fingers due to hardware and some necessary time consumption, and the ideal following experience is not achieved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an operation method of a touch screen device according to an embodiment of the present invention. The touch screen device operation method is suitable for touch screen devices with touch screens, such as mobile phones and tablet computers. As shown in fig. 2, the touch screen device operation method may include the following steps.
201. A first operation on a target operation interface is detected.
In this embodiment, the target operation interface may be a desktop of the touch screen device, an interface of an application displayed on the touch screen device, and the like, and the first operation may be a sliding operation, a dragging operation, and the like performed in the touch screen device, and specifically may be a right sliding, a left sliding, an up sliding, a down sliding, and the like.
202. And acquiring initial state parameters of the first operation.
In this embodiment, the initial state parameter is a parameter when the first operation is started, and may include at least one of an initial operation direction, an initial speed, an initial pressure value, an initial position, an initial displacement, an initial rotation direction, an initial rotation speed, and an initial rotation angle. It should be noted that the initial state parameter of the first operation is not limited to the above example, and other modes, such as initial acceleration, initial rotation acceleration, etc., may also be used.
For example, when the start state parameter includes the start operation direction, the obtaining the start state parameter of the first operation includes: acquiring coordinates of each touch point in the first N touch points of the first operation, where N is a positive integer, and specifically, for example, acquiring the N touch points in the android phone may be to acquire 3 touch points after the first operation is executed for 24 ms; and calculating the initial operation direction of the first operation according to the coordinates of each touch point in the first N touch points. In addition, the time for completing the touch of the N touch points can be detected, and the initial speed of the first operation can be calculated according to the time. In addition, a pressure sensor on the touch screen device may be used to detect a starting pressure value of the first operation, where the starting pressure value may be an average value of pressure values of N touch points before the first operation. In addition, the initial rotation direction and/or the initial rotation angle may be determined according to the coordinates of the first N touch points. The initial rotation speed can also be determined according to the touch completion time of the first N touch points and the coordinates of the first N touch points. The initial position may also be calculated according to coordinates of each of the first N touch points of the first operation. The examples are only used to explain the embodiments of the present invention, and should not be construed as limiting, and the starting status parameter may also include other status parameters at the start of the first operation.
203. And drawing a graph to be displayed according to the initial state parameter.
In this embodiment, after the initial state parameter of the first operation is obtained, the graph to be displayed, which may be displayed subsequently, is drawn according to the initial state parameter of the first operation, and the drawing sequence may be drawn according to the sequence of the time that may be displayed, so that the graph to be displayed first can be drawn as soon as possible, thereby shortening the display delay of the graph.
In this embodiment, a prediction model may be retrieved according to the initial state parameter; and drawing a graph to be displayed according to the prediction model. Wherein the prediction model is associated with the target operation interface, and the prediction model can be obtained and stored by the following means: at least one of historical actions, behaviors, habits, data and the like of the user on the previous operation of the target operation interface is obtained, characteristics in the historical operation are analyzed and counted through machine learning, and the process can be executed through a special prediction model generation module.
For example, in the machine learning stage, the past left sliding operation of the user on the Home desktop may be analyzed and counted to generate a prediction model, and the prediction model may include a to-be-displayed graph to be drawn, or may include parameters such as a display mode, a switching speed, and a display time of the to-be-displayed graph. After the prediction model is generated, when the user performs leftward sliding on the Home desktop, the model can be used for predicting the graph to be displayed, which is desired to be displayed when the user performs the first operation, and parameters such as the display speed and the time of the graph to be displayed can also be predicted.
The historical operation may include a time dimension operation on the target operation interface, such as a leftward sliding operation in a machine learning stage for a period of time, or a space dimension operation on the target operation interface, such as a leftward sliding operation in a certain area range on the operation interface in a machine learning stage for a period of time.
On the other hand, historical operations for generating a prediction model may increase over time, thereby increasing the amount of data used to generate the prediction model, and in general, a larger amount of data may generate a more accurate prediction model, with more statistical samples, the higher the accuracy. And when the data volume is large enough, accurately predicting the graph to be displayed, which is required to be drawn and corresponds to the first operation, through the generated prediction model.
More than one prediction model can be retrieved according to the initial state parameters, the graphs to be displayed and to be drawn corresponding to all the prediction models can be drawn, and the drawing sequence of the graphs to be displayed and corresponding to all the prediction models can be sequenced.
In addition, the examples are only for explaining the embodiments of the present invention and should not be construed as limiting.
In this embodiment, a corresponding learning record may be obtained according to the initial state parameter, where the learning record is generated and stored according to the historical operation of the target operation interface; and drawing a graph to be displayed according to the learning record. Wherein the learning record may be a curve containing a state parameter.
For example, please refer to fig. 3, fig. 3 is a schematic diagram of a method for determining a graph to be displayed according to an embodiment of the present invention, as shown in fig. 3, where 301 is a first operation detected on a target operation interface, which may be a touch operation performed on a touch screen, the initial state parameter may be at least one of an operation direction, an initial speed, an initial pressure value, an initial position, an initial displacement, an initial rotation direction, an initial rotation speed, and an initial rotation angle obtained according to a first N touch points 3011, 302 is a pre-stored learning record, which may be obtained by a terminal including a touch screen device through a learning process according to an input operation and analyzing a learning rule, and is stored in a learning record library, a learning record that is the same as the initial state parameter or has an absolute value different from the initial state parameter and is smaller than a preset threshold may be retrieved from the learning record library according to the initial state parameter, specifically, three learning records satisfying the initial state parameter 3021 are retrieved according to the above conditions as in the learning record library.
In addition, the matching degree of the initial touch track of the first operation and the curve track in the learning record library can be detected, and when the matching degree is greater than a preset threshold value, the curve is the learning record corresponding to the initial state parameter. The matching degree of the initial touch trajectory and the curve trajectory in the learning record library can be obtained by calculating the initial state parameters.
After the corresponding learning record is obtained, as shown in fig. 3, a graph 303 to be displayed, which may be displayed subsequently, is drawn according to the learning record, the graph to be displayed, which corresponds to each of the three learning records obtained, may be drawn and stored in the memory, and the drawing sequence of all the graphs to be displayed may be drawn according to the sequence of the time that may be displayed, so that the graph to be displayed first may be drawn as soon as possible, thereby shortening the display delay of the graph. In addition, the examples are only for explaining the embodiments of the present invention and should not be construed as limiting.
In this embodiment, each learning record may correspond to obtain a group of to-be-displayed graphs, each group of to-be-displayed graphs may include at least one to-be-displayed graph, the to-be-displayed graphs obtained from all the learning records may be stored, and the corresponding to-be-displayed graph is obtained according to the current coordinate of the first operation; on the other hand, each learning record may correspond to obtain a to-be-displayed graph, each to-be-displayed graph may include all to-be-displayed interfaces, a corresponding display area in the corresponding to-be-displayed graph may be obtained according to the current coordinates of the first operation, and the display area is displayed.
Wherein the learning record can be obtained by: in a learning process of a terminal including a touch screen device, when a second operation of the target operation interface is detected, acquiring an operation state parameter of the second operation, where the operation state parameter of the second operation may include at least one of an operation direction of the second operation, an operation speed of the second operation, a displacement of the second operation, an operation pressure value of the second operation, an operation position of the second operation, a rotation direction of the second operation, and a rotation angle of the second operation; saving the operation state parameters of the second operation and the target operation interface as a record group; and generating and saving the learning record according to the record group. In addition, when a third operation of the target operation interface is detected, an operation state parameter of the third operation can be acquired; and when the absolute value of the difference value between the operation state parameter of the third operation and the operation state parameter of the second operation is smaller than a preset value, storing the operation state parameter of the third operation and the target operation interface in the record group.
For example, the operation state parameter of the second operation may be acquired by: the operation direction of the second operation may be calculated according to the coordinates of each of the all touch points by acquiring the coordinates of all touch points of the second operation. In addition, the time for completing touch of all touch points or the time for completing the second operation may be detected, and the operation speed of the second operation may be calculated according to the time. In addition, an operation pressure value of the second operation may be detected using a pressure sensor on the touch screen device, and the operation pressure value may be an average value of pressure values of all touch points of the second operation. In addition, the rotation direction and/or the rotation angle of the second operation may be determined according to the coordinates of all the touch points. The rotation speed can also be determined according to the time when all touch points finish touch and the coordinates of all touch points. The operation position of the second operation can be calculated through the coordinates of all the touch points of the second operation. Likewise, the operation state parameters of the third operation are acquired in the same manner as the operation state parameters of the second operation. In addition, the examples are only for explaining the embodiments of the present invention, and should not be construed as limiting, and the status parameters of the second operation/third operation may also include other status parameters of the second operation/third operation.
When the absolute value of the difference between the state parameters of two operations is greater than or equal to the preset value, the two operations need to be stored as two record groups respectively. For example, when the state parameter is the operation direction, when the absolute value of the difference between the operation directions of two operations is less than 15 degrees, the target operation interface and the operation direction of the two operations may be recorded in one recording group, and when the absolute value of the difference between the operation directions of two operations is greater than or equal to 15 degrees, the target operation interface and the operation direction of the two operations may be recorded in two recording groups, respectively.
When a terminal including the touch screen device acquires enough operation parameters of the touch screen device operation in the learning process, namely, when enough state parameters are acquired in each record group, the terminal can analyze and count the state parameters in each record group to obtain a learning record.
204. And displaying according to the graph to be displayed.
In this embodiment, after the graph to be displayed is drawn according to the initial state parameter, the current coordinate of the first operation may be acquired, and a target display graph is determined and displayed according to the current coordinate and the graph to be displayed. The current coordinate refers to a current touch position of the first operation on the touch screen, and a current graph to be displayed can be determined by detecting the current touch position of the first operation in real time, so that the real-time performance of graph display is improved.
The target display graph may be included in the graph to be displayed, or may not be included in the graph to be displayed, but is drawn continuously, and the operation after the initial state in the first operation may be to display the graph to be displayed by only considering the influence on the graph to be displayed, or may be to continue drawing and displaying the graph in need, in addition to the graph to be displayed, which is influenced by the graph to be drawn.
For example, in the previous example, as shown in fig. 3, the graph to be displayed includes graphs 3031, 3032 and 3033 corresponding to the learning record 3022, when the learning record 3022 is a curve, the coordinates of points 30221, 30222 and 30223 on the learning record 3022 establish a corresponding relationship with the drawn graph 3031, 3032 and 3033 to be displayed, and a graph display is selected from the graph to be displayed according to the touch point of the first operation in real time according to the current coordinate and the coordinate of the corresponding point in the learning record. For example, if it is detected that the current coordinate of the first operation is at 3012, the corresponding coordinate 30222 in the corresponding learning record is obtained according to the current coordinate, and the graph 3032 to be displayed currently is found in the graph to be displayed correspondingly, and the graph 3032 is displayed. The graph 3031 to be displayed is drawn according to the corresponding learning record 3022. In addition, the examples are only for explaining the embodiments of the present invention and should not be construed as limiting.
In this embodiment, when it is detected that the first operation is ended, an ending state parameter of the first operation may be acquired; and determining the last graph required to be displayed according to the ending state parameter. Wherein the ending state parameter comprises at least one of an ending speed, an ending pressure value, a displacement of the first operation, and a duration of the first operation. In addition, the examples are only for explaining the embodiments of the present invention and should not be construed as limiting.
The process of acquiring the ending state parameter is similar to the process of acquiring the second operation state parameter, and details are not repeated in this embodiment. When the determined last graph needing to be displayed is the graph which is currently displayed, indicating that the influence of the first operation on the operation of the touch screen device is finished; and when the determined last required display graph is not the graph which is currently displayed, the influence of the first operation on the operation of the touch screen device is not finished, and the graph which is not displayed before the last required display graph and is required to be displayed is continuously displayed until the last required display graph is displayed, so that the end is not realized.
For example, referring to fig. 4, fig. 4 is a schematic diagram of a method for determining a last required display pattern according to an embodiment of the present invention, as shown in fig. 4, where 401 is a first operation, the first operation 401 starting at 4011 and ending at 4012, if an end state parameter, such as speed, when the speed is greater than the preset speed threshold, the last desired display graphic 402 may be obtained according to the speed, the last desired display graphic 402 may be the bottom of the browser interface, if the currently displayed graphic 403 is not the last desired display graphic 402, the display of the graphics between the current display graphic 403 and the last desired display graphic 402 continues in chronological order until the last desired display graphic 402 is displayed and the last desired display graphic 402 remains displayed. Similarly, the manner of obtaining and displaying the last required display graphic in the desktop of the terminal with the touch screen device and various applications can also be performed in the above manner, and the examples are only used for explaining the embodiments of the present invention, and should not be construed as limiting.
The last required display graph 402 may be included in the graph to be displayed, or may not be included in the graph to be displayed, and needs to be drawn. If the last required display graph 402 is not included in the graph to be displayed, the graph which is required to be displayed and is not included in the graph to be displayed can be drawn and displayed in the display process.
In the operation method of the touch screen device depicted in fig. 2, a first operation on a target operation interface is detected; acquiring initial state parameters of the first operation; drawing a graph to be displayed according to the initial state parameter; and displaying according to the graph to be displayed. The time delay of graphic display can be reduced because the graphic to be displayed can be drawn in advance by the initial state parameter of the first operation.
