Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Example one
Fig. 1 is a flowchart of a method for binding a button function according to a first embodiment of the present application. FIG. 2 is a schematic diagram of an application environment for a button function binding method. The button function binding method provided in this embodiment may be executed by the projection control end 210 in fig. 2, where the projection control end 210 may be implemented in a software and/or hardware manner, and the projection control end 210 may be formed by two or more physical entities, or may be formed by one physical entity. The projection control terminal 210 may be a terminal for controlling projection, such as a laptop, a desktop, a mobile phone, a tablet, or an interactive smart tablet.
The projector 220 may be an electronic device with a projection function, the projector 220 and the projection control terminal 210 may be connected by a wire/wireless connection, and the projector 220 may receive a projection image sent by the projection control terminal 210 and project the projection image to the projection whiteboard 230.
The projection whiteboard 230 may be an electronic whiteboard with touch sensing function. In practical application, the projection whiteboard may be specifically an electronic whiteboard provided with an infrared touch screen, an electromagnetic touch screen, a capacitive touch screen, and other touch screens. The projection whiteboard 230 and the projection control terminal 210 may be connected by wire/wireless.
First, in actual use, an electronic whiteboard generally has a display function and a touch sensing function, but a user may use only the electronic whiteboard to display a projection screen without using the display function. Therefore, in the above scenario, the electronic whiteboard used for projection, i.e., the projection whiteboard 230 described above.
The projection whiteboard 230 can sense a touch operation of a user through a touch sensing function, and generate a touch coordinate according to the sensed touch operation. The touch coordinates are determined according to the position touched by the touch operation. More specifically, a plane coordinate system on which the position touched by the touch operation is located, that is, the touch coordinate, may be constructed based on the projection whiteboard 230.
When the projection distance and the projection position between the projector 220 and the projection whiteboard 230 are correct, the picture projected by the projector 220 matches the size of the projection whiteboard 230. The touch coordinates generated by the touch operation sensed by the projection whiteboard correspond to the coordinates of each position on the projection screen, that is, the coordinates of each position on the screen displayed by the projection control terminal 210. Therefore, when the projection distance and the projection position between the projector 220 and the projection whiteboard 230 are correct, the user can simulate a click operation or a touch operation on the screen displayed by the projection control terminal 210 according to the user's touch operation on the projection whiteboard 230.
FIG. 3A isAnd when the projection distance is correct, the user clicks the schematic diagram of the projection white board. As shown in the figure, when the projection distance is correct, the image projected by the projector 220 matches the size of the projection white board 230. The projected picture comprises calling annotation function icon 1 and calling recording function icon 2, when the user clicks the annotation function icon 1 of the projection white board 230, the projection white board 230 generates a touch coordinate (x) according to the sensed touch operation1，y1) Will (x)1，y1) Sent to the projection control end 210, and the projection control end 210 determines (x)1，y1) The corresponding coordinate on the displayed picture is (x)1U，y1U) And on the displayed picture, aiming at (x)1U，y1U) The annotation function icon 1 performs a click operation or a touch operation to call an annotation function.
However, in practical applications, the projection distance or the projection position between the projector 220 and the projection whiteboard 230 may be inappropriate, which may cause a problem that the projection screen of the projector 220 is not matched with the projection whiteboard, making it difficult for the user to invoke the required program function.
Fig. 3B is a schematic diagram of a user clicking on a projection whiteboard when the projection distance is incorrect. As shown, when the projection distance is too short, the image projected by the projector 220 may be smaller than the projection white board 230. As shown by the solid line box in the projection whiteboard 230, the screen projected by the projector 220 when the projection distance is too short. For comparison, the content of the dashed box in the figure is used to indicate a picture when the projection distance is correct, and the picture of the solid box is smaller than the picture of the dashed box. When the user clicks the icon 1 of the projection whiteboard 230, the projection whiteboard 230 generates a touch coordinate (x) according to the sensed touch operation2，y2) Will (x)2，y2) Sent to the projection control end 210, and the projection control end 210 determines (x)2，y2) The corresponding coordinate on the displayed picture is (x)2U，y2U) And on the displayed picture, aiming at (x)2U，y2U) The recording function icon 2 is called to perform a click operation or a touch operation, and the recording function is called. Therefore, the user wants to call the annotation function but calls the annotation functionThe recording function is realized.
When the projection position between the projector 220 and the projection whiteboard 230 is incorrect, the above problem of calling function error also occurs, and will not be described herein.
Because the projection distance and the projection position are incorrect, the user is difficult to call the required program function, in the prior art, the user cannot control the projection control terminal 210 to call a certain program function by touching the projection white board 230, and the user can only operate the projection control terminal 210 to call a certain program function, which causes inconvenience in user operation. In order to solve the problem that it takes time for a user to call a program function, a first embodiment of the present application provides a method for binding a button function, which is described with reference to fig. 1 by taking an example that the method is applied to a projection control end 210, and the method may specifically include:
step S110, obtaining a button position of the projection whiteboard, wherein the projection whiteboard has a touch sensing function, and the button position is obtained by binding touch operation according to the function sensed by the projection whiteboard.
The button position may be a position of a button for calling a certain program function on the projection whiteboard. For example, an identifier of a button may be provided on the projection whiteboard 230, and accordingly, the position of the identifier of the button on the projection whiteboard 230, i.e., the button position. The button position may be specifically expressed as (x)1，y1)、(x2，y2)…(xN，yN) The set of coordinates may also be specifically expressed as one start point coordinate (x)1，y1) And dimensional parameters such as height H, width W, etc.
The function binding touch operation may be an operation for acquiring a button position by a user touching the projection whiteboard 230 in the process of binding the button function.
In a specific implementation, in the process of binding the button function, a user may perform a touch operation such as clicking or pressing on any position on the projection whiteboard 230. For the sake of explanation, this touch operation is named a function binding touch operation.
In practical applications, in order to prompt the user of the position of the button on the projection whiteboard 230 and the function corresponding to the button, an identifier of the button may be pasted on the projection whiteboard 230. The button marks may be of any shape, such as square, rectangular, circular, etc. The indicia of the buttons may be of any size, for example, a square button having a length and width of 5cm by 5 cm. The identification of the button can be provided anywhere on the projection whiteboard 230, for example, in the upper left corner of the projection whiteboard. The identification of the buttons may be any number. The button labels may be printed with a schematic and/or name of the function.
Fig. 4 is a schematic diagram of a button label on a projected whiteboard in one embodiment. As shown, a square sticker can be pasted on the projection whiteboard 230 as the button identifier. The sticker may have printed thereon a schematic icon and name for the button function, with button 231 being the "select" function and button 232 being the "eraser" function as shown.
When setting the button position, the user can perform a touch operation such as clicking or pressing on the edge of the button mark. For example, for a square button label, the user can click on each point on the edge of the button label.
In a specific implementation, the projection whiteboard 230 may sense a function binding touch operation of the user, and generate a touch coordinate according to the sensed function binding touch operation. The projection whiteboard 230 may send the touch coordinates to the projection control terminal 210. The projection control end 210 may be installed with a custom button configuration software, and after receiving the touch coordinate, the projection control end 210 may obtain the button position according to the touch coordinate through the custom button configuration software.
For example, the user may click on each point on the edge of the button identification. The projection whiteboard 230 senses a user's click and generates a touch coordinate (x)1，y1)、(x2，y2)…(xN，yN) A series of touch coordinates that the projection whiteboard 230 sends to the projection whiteboard 230. The projection whiteboard 230 may map the touch coordinates (x)1，y1)、(x2，y2)…(xN，yN) As the button position.
There may be various specific embodiments of the position of the touch operation acquisition button according to the function binding sensed by the projection whiteboard.
For example, for a square button label, the user can click on each point on the edge of the button label. The projection whiteboard 230 senses a user's click and generates touch coordinates. The projection control end 210 may determine a vertex coordinate according to the touch coordinate, calculate a button height and a button width according to the vertex coordinate, and use the vertex coordinate, the button height, and the button width as the button position.
For another example, for a circular button mark, the user may press the center of the button mark, and the projection whiteboard 230 senses the user's press to generate touch coordinates. The projection control end 210 may determine a button circle center according to the touch coordinates, and use the button circle center and a preset button radius as the button position.
For another example, the projection whiteboard generates a touch coordinate according to the sensed function binding touch operation, determines a button position according to the touch coordinate, and then sends the button position to the projection control end 210.
A person skilled in the art may select a specific implementation manner of obtaining the position of the button according to the function binding touch operation sensed by the projection whiteboard according to actual needs, which is not limited in the embodiment of the present application.
Step S120, acquiring a button function, and establishing a binding relationship between the button position and the button function, wherein the binding relationship is used for calling a touch operation according to the function call touch operation sensed by the projection whiteboard and calling the button function bound with the button position.
The button function may include various program functions on the projection control terminal 210, and the button function may be embodied as an identifier corresponding to a certain program function. The program function may specifically be a function of starting a browser, starting electronic whiteboard software, shortcut key operation, sending a global system message, sending a hardware message to a specific device port, and the like.
The function calling touch operation may be an operation in which a user touches the projection whiteboard during the projection process to call a button function.
In a specific implementation, the projection control terminal 210 may obtain the button function, and then bind the button position with the button function to establish a binding relationship between the button position and the button function.
The specific implementation of the get button function can be varied. For example, the user may write a function command for calling a button function, and input the function command to the projection control terminal 210. For another example, the projection control end 210 may preset a plurality of candidate button functions for the user to select, and the user may select one or more of the candidate button functions. Those skilled in the art can obtain the button function by using various specific embodiments according to actual needs, and the embodiment of the present application does not limit this.
There are many specific embodiments for establishing the binding relationship between the button positions and the button functions. For example, the button position may be specifically a coordinate, the button function may be specifically a function command, and the projection control end 210 may write the coordinate and the function command into a binding relationship configuration file and store the binding relationship in the local storage, so that the binding relationship between the button position and the button function is established and recorded by using the binding relationship configuration file. Those skilled in the art can adopt various specific embodiments according to actual requirements to establish a binding relationship between a button position and a button function, which is not limited in the embodiment of the present application.
When performing projection, when a user performs a function calling touch operation on the projection whiteboard 230, the projection whiteboard 230 calls the touch operation according to the sensed function, generates a touch coordinate, sends the touch coordinate to the projection control end 210, the projection control end 210 determines that the touch coordinate is matched with a button position, and the projection control end 210 calls the button function bound with the button position according to the binding relationship between the button position and the button function.
For example, the projection whiteboard 230 has a sticker identifying "launch browser button" affixed theretoIn the projection process, the user clicks the sticker of the "start browser button", and the projection white board 230 senses the click of the user to generate a touch coordinate (x)1，y1) And transmits the touch coordinates (x)1，y1) To the projection control terminal 210, the projection control terminal 210 determines the touch coordinate (x)1，y1) And matching a certain button position, and determining that the button position is in a binding relationship with a function of starting the browser, so that the projection control terminal 210 calls a program function of starting the browser to start the browser. After the projection control end 210 starts the browser, the display screen of the projection control end 210 displays the browser interface, and the browser interface displayed by the projection control end 210 can be projected onto the projection white board 230 through the projector 220.
According to the technical scheme of the embodiment of the application, the button positions of the projection whiteboard are obtained by binding the touch operation according to the functions sensed by the projection whiteboard, and the binding relation between the button functions and the button positions is established. When projection is carried out, according to the binding relation between the button functions and the button positions, when the projection white board senses function calling touch operation aiming at the button positions, the button functions bound with the button positions can be called. Therefore, the user can call the program function of the projection control terminal through touch operation on the projection white board without operating on the projection control terminal, and convenience of calling the program function by the user is improved.
Further, the button positions are determined through function binding touch operation of a user on the projection white board, and the button functions are bound to the button positions, so that any button functions can be bound to any position on the projection white board through simple touch operation. The user does not need to write complex user-defined button codes by himself while the user's requirement for the user-defined button is realized, and the cost of the user-defined button is reduced. Moreover, the user-defined button can be realized through simple touch operation, so that the user can adjust the position and the function of the button according to the requirement at any time, and the flexibility of the user-defined button is improved.
Further, since any button function can be bound to any position on the projection whiteboard, when the touch sensing function of the button position on the projection whiteboard where the button function has been bound is abnormal, the user can bind the button function to another position again to obtain a new button position. Therefore, the problem that the user-defined button cannot be used due to the abnormal touch induction function of the button position on the projection white board is solved. Moreover, even if the touch sensing function of the button position on the projection white board is abnormal, the button function can be continuously used without maintaining or replacing the whole projection white board, and the maintenance cost of the projection white board is reduced.
Optionally, the step S110 includes:
receiving a function binding touch coordinate of the projection white board; the function binding touch coordinate is generated by the projection whiteboard according to the function binding touch operation; and generating the button position according to the function binding touch coordinate.
The function-bound touch coordinates may be coordinates generated according to a function-bound touch operation performed by the user on the projection whiteboard 230.
In a specific implementation, the projection whiteboard 230 may sense a function binding touch operation of a user, generate a touch coordinate according to the sensed function binding touch operation, and send the touch coordinate to the projection control end 210.
According to the technical scheme of the embodiment of the application, the projection white board generates the function binding touch coordinate according to the function binding touch operation, and the projection control end generates the button position according to the function binding touch coordinate and the function binding touch coordinate, so that the projection white board only needs to have a simple touch sensing function, the requirement of a user on a user-defined button can be met, and the design cost and the hardware cost of the projection white board are reduced.
Optionally, the generating the button position according to the function binding touch coordinate includes:
determining vertex coordinates in the function binding touch coordinates; calculating the coordinate distance between the vertex coordinates to obtain the height and the width of the button; generating the button position; the button position includes the vertex coordinates, the button height, and the button width.
Wherein the vertex coordinates may be coordinates of one or more vertices in the rectangular button. For example, the coordinates of the vertex at the lower right corner of the button, and the coordinates of the vertex at the upper left corner of the button.
Wherein the button height may be the height of the button. The button width may be the width of the button.
Wherein, the coordinate distance may be a distance of the vertex coordinate in a two-dimensional coordinate system.
In a specific implementation, a user can touch at multiple points on the projection whiteboard 230, thereby obtaining multiple function-bound touch coordinates. For the plurality of function-bound touch coordinates, the projection control end 210 may determine one or more vertex coordinates. For example, for a rectangular button, the coordinates of the four vertices of the rectangle may be determined.
After determining the vertex coordinates, the coordinate distance between the vertex coordinates may be calculated, resulting in a button height and a button width. Finally, the vertex coordinates, button height, button width may be taken as button positions.
For example, for a rectangular button, the coordinates of the vertices of the upper left corner, the lower left corner, and the lower right corner of the rectangle may be determined as vertex coordinates. Calculating the coordinate distance between the vertexes of the upper left corner and the lower left corner to obtain the height of the rectangle as the height of the button; and calculating the coordinate distance between the vertexes of the upper left corner and the upper right corner to obtain the width of the rectangle as the width of the button.
For another example, for a rectangular button, the coordinates of the vertices of the upper left corner and the lower right corner of the rectangle may be determined as vertex coordinates. And calculating the longitudinal coordinate distance between the vertexes through the y-axis coordinates of the vertexes of the upper left corner and the lower right corner to obtain the height of the rectangle as the height of the button. And calculating the transverse coordinate distance between the vertexes through the x-axis coordinates of the vertexes of the upper left corner and the lower right corner to obtain the width of the rectangle as the width of the button.
In practical application, the process of obtaining vertex coordinates, button heights, and button widths for a plurality of function binding touch coordinates may be understood as a process of solving a circumscribed rectangle for a plurality of function binding touch coordinates. Binding a plurality of function binding touch coordinates to serve as a set PL of coordinate points, and solving a circumscribed rectangle R of the set PL, wherein the circumscribed rectangle R comprises vertex coordinates of R, height and width of R.
First, the coordinates of the top left corner vertex and the coordinates of the bottom right corner vertex are calculated from the set PL, assuming PLiFor the elements of the set PL, MinX, MinY, MaxX, and MaxY can be calculated by the following formulas:
MinX＝Min(PLi.X)；MinY＝Min(PLi.Y)；MaxX＝Max(PLi.X)；MaxY＝Max(PLi.Y)
then, the coordinates of the top left corner vertex and the coordinates of the bottom right corner vertex are calculated by the following formulas:
LeftTopPoint＝(MinX，MinY)；RightBottomPoint＝(MaxX，MaxY)
the circumscribed rectangle R can be represented as the coordinates of the top left corner vertex and the coordinates of the bottom right corner vertex:
R＝(LeftTopPoint，RightBottomPoint)
finally, the height and width of the rectangle are calculated by the following formula:
R.Width＝RightBottomPoint.X-LeftTopPoint.X
R.Height＝RightBottomPoint.Y-LeftTopPoint.Y
according to the technical scheme of the embodiment of the application, the vertex coordinates of the touch coordinates are bound according to the functions, the button height and the button width are determined according to the coordinate distance between the vertex coordinates, and the vertex coordinates, the button height and the button width are used as the button positions.
Optionally, the establishing a binding relationship between the button position and the button function includes:
generating function instance code for the button function; generating an instance identifier corresponding to the function instance code; generating array elements; the array element comprises the instance identification and the button position; and adding the array elements to a preset initial array to obtain a binding relation array.
The function instance code may be code for invoking instantiation of a program function on the projection control terminal 210.
The binding relationship array may be an ordered sequence of elements that records the binding relationship between the button position and the button function.
In a specific implementation, multiple object instances may be created, i.e., code for invoking button functions is generated as function instance code. For example, a configuration file in a JSON (Object Notation) format may be created, where a command name and a button position corresponding to a button function are recorded in the configuration file, and then a parser is called to parse the configuration file to create a plurality of Object instances, so as to obtain a function instance code. An object instance may inherit from a Command class, and example code for a defined Command class is as follows:
public class Command
{
public int Id{set；get；}
public Button Button{set；get；}
}
public class Button
{
public int X{set；get；}
public int Y{set；get；}
public int Width{set；get；}
public int Height{set；get；}
}
after generating the function instance code, an instance identification corresponding to the function instance code may be generated accordingly. For example, an ID may be extracted from the function instance code as an instance identification.
Then, an array element containing the instance identifier and the button position is generated, and the array element is added to a preset initial array to obtain a binding relation array. For example, an array L is preset, an array element is formed by the instance identifier ID, the vertex coordinates (x, y), the button height H and the button width W, and the array element is added to the array L to obtain an array L' as the binding relationship array.
Therefore, the binding relationship array comprises a plurality of array elements, each array element records the corresponding relationship between the button position and the instance identifier, the corresponding function instance code can be determined according to the instance identifier, and the function instance code is used for calling the corresponding button function, that is, the binding relationship between the button position and the button function is established.
Optionally, the generating a function instance code of the button function includes:
acquiring a function configuration file of the button function; extracting a function name from the function configuration file; determining a function type according to the function name; and analyzing the function configuration file according to the function category to obtain the function instance code.
The function configuration file may be a file for configuring a binding relationship between a button position and a button function.
Wherein the function category may be a category of button functions. For example, functions may be divided into categories such as shortcut keys, launching software, browser open links, sending global system messages, sending hardware messages, and so on.
In a specific implementation, a user may write a configuration file in the projection control end 210, and the projection control end 210 may use the configuration file as a function configuration file. The file format of the function configuration file can be various, and in practical application, the JSON format can be adopted as the file format of the configuration file.
In practical applications, in order to configure the binding relationship between the button function and the button position by using the function profile, a command name and a button position corresponding to the button function may be recorded in the function profile. An example of an initial JSON configuration file is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command": "command of button"
}
Wherein, the values of "X" and "Y" can be obtained according to the vertex coordinates, the values of "Width" and "Height" can be obtained according to the button Width and the button Height, and the value of "Command" can be input by the user. The numerical value of the Command may include a plurality of attributes, for example, attributes such as "Name", "Keys", "Path", and the like, and after the numerical values of the attributes in the JSON configuration file are filled in, the function configuration file can be obtained. The function configuration file may be stored locally at the projection control end 210, for example, C: \ Program Files (x86) \ project File \ button.
When the custom button configuration software of the projection control end 210 is started, the custom button configuration software may run in the background of the projection control end 210. The custom button configuration software may monitor the generation or modification of functional configuration files while running. And when the new functional configuration file is changed or the functional configuration file is modified, reading the functional configuration file, and thus obtaining the functional configuration file.
After the function profile is obtained, the function name may be extracted from the function profile. For example, from a function configuration file in JSON format, a numerical value of the "Name" field is extracted as a function Name.
The function category can be determined by the proposed function name. For example, a function configuration file in JSON format, where the value of the "Name" attribute is "MCU", and the function type is "send hardware message"; the value of the Name attribute is ShortKey, and the function type is shortcut key.
After the function type is determined, an analyzer corresponding to the function type can be called to analyze the function configuration file and create a corresponding instance so as to obtain a function instance code.
According to the technical scheme of the embodiment of the application, the button position and the button function are bound in a configuration file mode, the button position and the button function can be adjusted in a configuration file modification mode, a user does not need to perform complex operation, and convenience of user-defined buttons is improved.
Optionally, the function category is a shortcut key category, and the analyzing the function configuration file according to the function category to obtain the function instance code includes:
calling a shortcut key function analyzer to analyze the function configuration file to obtain keyboard keys; generating the function instance code; the function instance code includes the keyboard keys.
In specific implementation, when the function type is a shortcut key type, a shortcut key function parser may be called to parse the function configuration file to obtain the keyboard keys. Then, a function instance code containing the keyboard keys is generated. For example, information of the function profile record in JSON format is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command"：
{
"Name"："ShortKey"，
"Keys"："Ctrl，S"
}
according to the value 'ShortKey' of 'Name', the function type can be determined to be the shortcut key type. And calling a shortcut key function analyzer to analyze the function configuration file. In the specific process of analysis, the value of the "Keys" attribute can be read to obtain "Ctrl" and "S" as the Keys of the keyboard. The keyboard key of Ctrl + S can realize the function of saving the shortcut key of the file. After the function configuration file is analyzed, a function instance code is created as follows:
public class ShortKeyCommand：Command
{
public string[]Keys{set；get；}
}
and executing the function instance code to realize the function of quickly saving files.
Of course, in practical application, different keyboard keys and combinations thereof can be set to realize corresponding shortcut key functions. For example, "win + d" may display the desktop, "alt + F4" may close the window, "PageUp" and "PageDown" may enable PPT courseware paging. Those skilled in the art can set different keyboard keys and combinations thereof according to actual needs.
It should be noted that the button function for implementing the shortcut key function is implemented by calling the global keyboard simulator and implementing a key press by software simulation of the keyboard key press.
Optionally, the function type is a software starting type, and the analyzing the function configuration file according to the function type to obtain the function instance code includes:
calling a starting software function analyzer to analyze the function configuration file to obtain a software absolute path and a starting parameter; generating the function instance code; the function instance code includes the software absolute path and the startup parameters.
In specific implementation, when the function type is the start software type, a start software function analyzer can be called to analyze the function configuration file to obtain the software absolute path and the start parameters. Then, function instance code is generated that contains the software absolute path and startup parameters. For example, information of the function profile record in JSON format is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command"：
{
"Name"："Excuse"，
"Path"："C:\Program Files(x86)\Seewo\EasiNote5\swenlauncher\swenlauncher.exe"
"Args"：
[
"display"，
]
}
according to the value "Excuse" of "Name", the function category can be determined as the boot software category. And calling a starting software function analyzer to analyze the function configuration file. In the specific process of analysis, the value C of the attribute of 'Path' can be read, namely \ Program Files (x86) \ Seewo \ EasiNote5\ swenlaunter. The value "display" of "Args" can be read as a startup parameter of the whiteboard software.
After the function configuration file is analyzed, a function instance code is created as follows:
public class Excuse：Command
{
///<summary>
///C:\Program Files(x86)\Seewo\EasiNote5\swenlauncher\swenlauncher.exe
///</summary>
public string Path{get；set；}
///<summary>
///display
///</summary>
public string[]Args{get；set；}
}
the function instance code is executed, the function of starting the whiteboard software can be realized, and the teaching mode is entered according to the starting parameter 'display'.
It should be noted that the function of starting the software is to start the software by calling a process initiator provided by the system, and meanwhile, the process initiator provided by the system supports the transmission of parameters to the started software, and if the command of starting the software has parameters, the parameters of the start are transmitted.
It should be further noted that, in practical applications, a user-defined and more complex function can be implemented in combination with the incoming parameters. For example, a user needs to set a button function to download a document from a certain website, and then open the document using Word software. To implement this function, a facility program may be developed, in which the value of the "Path" attribute is set to the Path where the facility program is located, one value of "Args" is set to the website where the document needs to be downloaded, and the other value of "Args" is set to the Path of Word software. By the method, the functions can be expanded, and the user-defined and complex functions are met.
Optionally, the function category is a browser open link category, and the analyzing the function configuration file according to the function category to obtain the function instance code includes:
calling a link analyzer to analyze the function configuration file to obtain a link website; generating the function instance code; the function instance code includes the link website.
In specific implementation, when the function type is a browser open link type, a link parser may be called to parse the function configuration file to obtain a link website. Then, a function instance code containing the linked web address is generated.
For example, information of the function profile record in JSON format is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command"：
{
"Name"："UrlLauncher"，
"Url"："http://seewo.com"
}
}
according to the value "UrlLauncher" of the "Name", the function category can be determined as the browser open link category. And calling a link analyzer to analyze the function configuration file. In the specific process of the analysis, the value of the attribute of 'Url', http:// seewo.
After the function configuration file is analyzed, a function instance code is created as follows:
public class UrlLauncher：Command
{
///<summary>
///http://seewo.com
///</summary>
public string Url{get；set；}
}
com is accessed to the website through a browser.
It should be noted that the command for invoking the browser is to invoke a process launcher provided by the system, launch a default browser of the system, and transfer the launched link by means of a parameter, so that the link can be opened by the browser.
Optionally, the function type is a type of sending a global system message, and the analyzing the function configuration file according to the function type to obtain the function instance code includes:
calling a system message analyzer to analyze the function configuration file to obtain a global system message; generating the function instance code; the function instance code includes the global system message.
In a specific implementation, when the function type is the type of sending the global system message, a system message parser may be called to parse the function configuration file to obtain the global system message. Then, function instance code is generated that contains the global system message. For example, information of the function profile record in JSON format is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command"：
{
"Name"："MSG"，
"WindowsMessage"："WM_PAINT"
}
}
according to the value "MSG" of "Name", the function category can be determined as the category of sending global system messages. And calling a system message analyzer to analyze the function configuration file. In the specific process of parsing, the value "WM _ PAINT" of the "windows message" attribute may be read as a global system message. After the function configuration file is analyzed, a function instance code is created as follows:
public class WinMsg:Command
{
///<summary>
///WM_PAINT
///</summary>
public int Msg{set；get；}
}
in the projection process, a certain software operation may be jammed, and therefore, forced software refreshing is required to restore the normal operation of the software. Executing the function example code can realize the function of forcibly refreshing the software by sending a Windows global system message.
It should be noted that the function of sending the global Windows message is implemented by directly sending the global Windows message.
Optionally, the function type is a hardware message sending type, and the analyzing the function configuration file according to the function type to obtain the function instance code includes:
calling a hardware message analyzer to analyze the function configuration file to obtain message content, message length, hardware identification and a sending port; generating the function instance code; the function instance code includes the message content, the message length, the hardware identification, and the send port.
In specific implementation, when the function type is a hardware message sending type, a hardware message parser may be called to parse the function configuration file to obtain information of message content, message length, hardware identifier, a sending port, and the like. Then, a function instance code is generated that contains the message content, the message length, the hardware identification, and the sending port. For example, information of the function profile record in JSON format is as follows:
{
"X": "x-coordinate of the button",
"Y": "the y-coordinate of the button",
"Width": "width of the button",
"Height": "height of the button",
"Command"：
{
"Name"："MCU"，
"PID": "PID (Product ID, device identification code) of usb (Universal Serial BUS) device"
"VID": "VID (Vendor ID, supplier identification code) of usb device"
"KEY": 'transmitting port'

}
}
According to the value "MCU" of "Name", the function type can be determined as the type of sending hardware message. And calling a hardware message analyzer to analyze the function configuration file. In the specific process of the analysis, the values of PID, VID, KEY, Message and Length can be read to obtain the hardware identifier, the sending port, the Message content and the Message Length. After the function configuration file is analyzed, a function instance code is created as follows:
public class Mcu:Command
{
///<summary>
pid of// usb device
///</summary>
public int Pid{set；get；}
///<summary>
Vid of// usb device
///</summary>
public int Vid{set；get；}
///<summary>
// usb device port
///</summary>
public string Key{set；get；}
///<summary>
// message content
///</summary>
public string Message{set；get；}
///<summary>
// message Length
///</summary>
public int Length{set；get；}
}
Executing the function instance code can send hardware message to the port of the specific USB device according to PID and VID, so as to realize the function of sending the hardware message to the specific hardware. For example, during the projection process, the projection whiteboard 230 and the projector 220 are connected via USB. By sending a hardware message to projector 220, projector 220 may be controlled to adjust the brightness of the projection.
It should be noted that, sending the hardware message requires first parsing the hardware message into byte arrays, where the parsing method may be to group the character strings into two character groups, combine two characters into one byte array in a manner of converting the two characters into one byte, determine whether the current byte array is the same as the message length to be sent, and if the length of the byte array is smaller than the message length to be sent, fill 0 until the length of the byte array is the same as the message length. And then calling the USB connector to find the corresponding USB sending hardware message.
Optionally, the method further comprises: receiving a function calling touch coordinate of the projection whiteboard; the function calling touch coordinate is generated according to the function calling touch operation; traversing array elements in the binding relation array to obtain a target array element; the button position of the target array element is matched with the function calling touch coordinate; and calling the button function according to the target array element.
The function call touch coordinates may be coordinates generated according to a function call touch operation performed by the user on the projection whiteboard 230.
In a specific implementation, during the projection process, a user may perform a touch operation such as clicking, pressing, or the like on a specific position on the projection whiteboard 230.
In practical applications, in order to prompt the user of a specific position of a button on the projection whiteboard 230 and a function corresponding to the button, an identifier of the button may be pasted on the projection whiteboard 230. The user can perform a touch operation such as clicking, pressing, or the like on the mark on the projection whiteboard 230.
The projection whiteboard 230 generates a touch coordinate according to the function call touch operation, and obtains a function call touch coordinate. The projection whiteboard 230 transmits the function call touch coordinates to the projection control terminal 210. The projection control end 210 matches the function call touch coordinate with each array element in the binding relationship array, and takes the array element whose button position matches the function call touch coordinate as a target array element.
For example, the coordinates clicked by the user on the projection whiteboard 230 are (X, Y), and when the button position (vertex coordinates (X, Y), button Height, button Width) of the nth array element Ln in the L array satisfies the following formula, it can be determined that the coordinates match the button position:
x≥Ln.X&&x≤Ln.X+L_n.Width&&y≥Ln.Y&&y≤Ln.Y+Ln.Height
according to the instance identifier in the target array element, the corresponding function instance code can be determined, and the function instance code is executed, namely, the corresponding button function can be called.
For example, when the user clicks the sticker identifier of "start whiteboard software" on the projection whiteboard 230, the projection control terminal executes the function instance code for starting the whiteboard software, and the projection control terminal 210 can start the whiteboard software. The activated whiteboard software is projected onto the projection whiteboard 230 by the projector 220.
According to the technical scheme of the embodiment of the application, in the projection process, the projection white board sends the function calling touch coordinates generated by the function calling touch operation of the induction user to the projection control end, the projection control end calls the button function according to the matching result of the function calling touch coordinates and the button position, in the process, the projection white board only needs to execute the processing of generating the coordinates and sending the coordinates without carrying out complex processing, and therefore the design cost and the hardware cost of the projection white board are saved while the button function is conveniently called.
Optionally, the invoking the button function according to the target array element includes:
acquiring an example identifier in the target array element to obtain a target example identifier; acquiring a function instance code corresponding to the target instance identifier to obtain a target instance code; and executing the target instance code to call the button function corresponding to the target instance code.
In a specific implementation, after the target array element is determined, the projection control end 210 may extract an instance identifier from the target array element, and use the instance identifier as a target instance identifier, and according to the target instance identifier, may extract a corresponding function instance code as a target instance code. Executing the object instance code may call the corresponding button function on the projection control terminal 210.
Optionally, after the receiving the function call touch coordinate of the projection whiteboard, the method further includes:
extracting a touch pressing coordinate and a touch lifting coordinate from the function calling touch coordinate; calculating a coordinate distance between the touch down coordinate and the touch up coordinate; determining that a coordinate distance between the touch down coordinate and the touch up coordinate is smaller than a preset distance threshold; and executing the step of traversing the array elements in the binding relation array to obtain target array elements.
The touch down coordinates may be coordinates generated when the user starts a touch operation. The touch-up coordinates may be coordinates generated when the user ends the touch operation. The coordinate distance may be a distance of the coordinates in a two-dimensional coordinate system.
In a specific implementation, the projection control terminal 210 may obtain a plurality of consecutive function call touch coordinates, and determine a touch down coordinate and a touch up coordinate in the plurality of consecutive function call touch coordinates. For example, when a function calling touch operation is sensed to generate function calling touch coordinates, the current time is recorded as the touch time of the function calling touch coordinates, the function calling touch coordinate with the earliest touch time is determined as the touch pressing coordinate, and the function calling touch coordinate with the latest touch time is determined as the touch lifting coordinate according to the touch time of each function calling touch coordinate. And then, calculating a coordinate distance between the touch down coordinate and the touch up coordinate, and when the calculated coordinate distance is smaller than a preset distance threshold, executing a step of traversing array elements in the binding relation array to obtain a target array element.
In practical applications, there may be a case where a button of the projection whiteboard 230 is touched by mistake due to an erroneous operation. For example, when a user explains a projection image of the projection whiteboard 230, the user may slide on the projection whiteboard 230 with a finger, press the projection whiteboard 230 at a certain position and lift the projection whiteboard 230 after sliding to another position, and if the user passes through a button position during the sliding process, the user may trigger the calling of the button function. Therefore, when the coordinate distance between the touch-down coordinate and the touch-up coordinate is large, it indicates that the user is not performing a touch operation such as clicking or pressing at a certain position of the projection whiteboard, but a certain misoperation, and even if the function calling touch coordinate matches a certain button position, the corresponding button function does not need to be called.
In the technical scheme of the embodiment of the application, the touch down coordinate and the touch up coordinate are determined in the function calling touch coordinate, and when the coordinate distance between the touch down coordinate and the touch up coordinate is smaller than a preset distance threshold, the step of traversing the array elements in the binding relation array to obtain the target array element is started to call the button function according to the target array element, so that the problem that the button function is called mistakenly due to misoperation of a user is avoided.
Optionally, after the receiving the function-bound touch coordinates of the projection whiteboard, the method further includes: generating a touch prompt image; the touch prompt image comprises a touch prompt identifier; the position of the touch prompt identifier on the touch prompt image is determined according to the function binding touch coordinate; sending the touch prompt image to a projector; and the touch prompt image is used for projecting to the projection white board by the projector so as to prompt the user of the position of the function binding touch coordinate on the projection white board through the touch prompt identifier.
The touch prompt image may be an image including a touch prompt identifier. The touch prompt identification can be an identification for prompting the user to functionally bind the location of the touch coordinates on the projection whiteboard 230. For example, a highlighted dot, or a red-sided box.
In a specific implementation, after receiving the function binding touch coordinate of the projection whiteboard 230, the projection control end 210 may generate an image, use the image as a plane coordinate system, determine, in the plane coordinate system, an identifier coordinate that is the same as the function binding touch coordinate, and add a touch prompt identifier to the identifier coordinate, thereby obtaining a touch prompt image. Then, the touch prompt image is sent to the projector 220, and the projector 220 projects the touch prompt image to the projection whiteboard 230, so that the touch prompt image is displayed on the projection whiteboard 230, and the user views the projection whiteboard 230, and can know the position of the function binding touch coordinate, generated by the projection whiteboard 230 according to the sensed function binding touch operation, on the projection whiteboard 230 according to the position of the touch prompt identifier in the touch prompt image.
In practical applications, if the function-bound touch coordinates are not the coordinates required by the user, the user may perform the touch operation again to re-determine the function-bound touch coordinates. For example, in order to prompt the user of the position of the button on the projection whiteboard 230 and the function corresponding to the button, an identifier of the button may be pasted on the projection whiteboard 230. The user needs to click on the identifier so that the function binding touch coordinate generated by the click coincides with the position of the identifier of the button on the projection whiteboard 230. If the function-bound touch coordinates deviate from the identity of the button, the user needs to re-click to re-determine the function-bound touch coordinates.
FIG. 5 is a diagram of a scenario of a touch prompt, under an embodiment. As shown in the figure, a user performs a function binding touch operation at a certain position on the projection whiteboard 230, the projection whiteboard 230 senses the function binding touch operation to generate a function binding touch coordinate, the function binding touch coordinate is sent to the projection control end 210, the projection control end 210 generates a touch prompt image 233 according to the function binding touch coordinate and sends the touch prompt image 233 to the projector 220, the projector 220 projects the touch prompt image to the projection whiteboard 230, the touch prompt image 233 is displayed on the projection whiteboard 230, wherein the touch prompt image 233 contains a highlight dot, which is a touch prompt identifier, and the user can know the position of the function binding touch coordinate generated by the projection whiteboard 230 according to the sensed function binding touch operation on the projection whiteboard 230 through the highlight dot.
According to the technical scheme of the embodiment of the application, the touch prompt image containing the touch prompt identifier is generated by binding the touch coordinate according to the function, the touch prompt image is sent to the projector, the projector projects the touch prompt image to the projection white board, and a user can know the position of the function binding touch coordinate on the projection white board through the position of the touch prompt identifier on the touch prompt image, so that the problem of button position positioning error caused by the fact that the function binding touch coordinate is not in accordance with the coordinate required by the user is solved.
In addition, according to the technical scheme of the embodiment of the application, the projection function of the projector is utilized to assist the user in positioning the button position, and the display function does not need to be added on the projection white board, so that the hardware cost and the design cost of the projection white board are saved.
Example two
Fig. 6 is a flowchart of a method for invoking a button function according to a second embodiment of the present application. The button function calling method provided in this embodiment may be executed by the projection control terminal 210 in fig. 2. Specifically, referring to fig. 6, the method for invoking a button function according to the second embodiment of the present application specifically includes:
step S210, obtaining a button position of the projection whiteboard, wherein the projection whiteboard has a touch sensing function, and the button position is obtained by binding touch operation according to the function sensed by the projection whiteboard.
In a specific implementation, in the process of binding the button function, a user may perform a touch operation such as clicking or pressing on any position on the projection whiteboard 230. For the sake of explanation, this touch operation is named a function binding touch operation. The projection whiteboard 230 may sense a function-binding touch operation of the user and generate touch coordinates according to the sensed function-binding touch operation. The projection whiteboard 230 may send the touch coordinates to the projection control terminal 210. The projection control end 210 may be installed with a custom button configuration software, and after receiving the touch coordinate, the projection control end 210 may obtain the button position according to the touch coordinate through the custom button configuration software.
The button position may be specifically expressed as (x)1，y1)、(x2，y2)…(xN，yN) The set of coordinates may also be specifically expressed as one start point coordinate (x)1，y1) And dimensional parameters such as height H, width W, etc.
Step S220, acquiring a button function, and establishing a binding relationship between the button position and the button function.
In a specific implementation, the projection control terminal 210 may obtain the button function, and then bind the button position with the button function to establish a binding relationship between the button position and the button function.
Step S230, receiving a function calling touch coordinate of the projection whiteboard; and the function calling touch coordinates are generated according to the function calling touch operation sensed by the projection whiteboard.
In a specific implementation, the projection whiteboard 230 generates corresponding touch coordinates as function call touch coordinates according to the function call touch operation. The projection whiteboard 230 transmits the function call touch coordinates to the projection control terminal 210.
Step S240, determining that the function calling touch coordinate matches the button position, and calling a button function bound to the button position.
In specific implementation, the touch coordinates can be matched with a plurality of button positions, and when the matched button positions exist in the touch coordinates, the button functions bound with the button positions are called.
For example, the button position is the start point coordinate (x)1，y1) And height H, width W, such that a range of coordinates, touch coordinates (x), can be determinedN，yN) And when the touch button is within the coordinate range, the touch coordinate is determined to be matched with the button position.
In practical application, an array of button positions and button functions can be pre-established, and the button positions matched with the touch coordinates can be determined in a mode of traversing the array. The way of establishing an array and traversing the array has been described in detail in the first embodiment, and is not described herein again.
According to the technical scheme of the embodiment of the application, the button positions of the projection whiteboard are obtained by binding the touch operation according to the functions sensed by the projection whiteboard, and the binding relation between the button functions and the button positions is established. When projection is carried out, according to the binding relation between the button functions and the button positions, when the projection white board senses function calling touch operation aiming at the button positions, the button functions bound with the button positions can be called. Therefore, the user can call the program function of the projection control terminal through touch operation on the projection white board without operating on the projection control terminal, and convenience of calling the program function by the user is improved.
Further, the button positions are determined through function binding touch operation of a user on the projection white board, and the button functions are bound to the button positions, so that any button functions can be bound to any position on the projection white board through simple touch operation. The user does not need to write complex user-defined button codes by himself while the user's requirement for the user-defined button is realized, and the cost of the user-defined button is reduced. Moreover, the user-defined button can be realized through simple touch operation, so that the user can adjust the position and the function of the button according to the requirement at any time, and the flexibility of the user-defined button is improved.
Further, since any button function can be bound to any position on the projection whiteboard, when the touch sensing function of the button position on the projection whiteboard where the button function has been bound is abnormal, the user can bind the button function to another position again to obtain a new button position. Therefore, the problem that the user-defined button cannot be used due to the abnormal touch induction function of the button position on the projection white board is solved. Moreover, even if the touch sensing function of the button position on the projection white board is abnormal, the button function can be continuously used without maintaining or replacing the whole projection white board, and the maintenance cost of the projection white board is reduced.
Optionally, the establishing a binding relationship between the button position and the button function includes:
generating function instance code for the button function; generating an instance identifier corresponding to the function instance code; generating array elements; the array element comprises the instance identification and the button position; and adding the array elements to a preset initial array to obtain a binding relation array.
