[0044] Various aspects and features of the present application are described herein with reference to the accompanying drawings.

Therefore, the above description should not be considered as limiting, but only as an example of an embodiment. Other modifications within the scope and spirit of the present application will occur to those skilled in the art.

[0046] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0049] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0050] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0051] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0052] The implementation method of full-screen handwriting provided in the embodiment of the present application is applied to electronic devices, which can realize the function of full-screen handwriting on electronic devices, and is applicable to a variety of electronic devices and a variety of applications on electronic devices, with good versatility and compatibility. To facilitate understanding of the present application, a method for implementing full-screen handwriting provided in the present application is first introduced in detail.

[0053] like Figure 1 As shown, it is a flowchart of the method for implementing full-screen handwriting provided in an embodiment of the present application, wherein the specific steps include S101-S103.

[0054] S101, determining that the target application is in a text input mode, and controlling a virtual screen to obtain an input track in response to a track input operation of an input device; wherein the virtual screen is located on a data transmission path between a driver layer and a framework layer of the electronic device.

[0055] In a specific implementation, the system of the electronic device includes a driver layer, a framework layer and an application layer, and the driver layer is located at the bottom layer, the application layer is located at the top layer, the framework layer is located between the driver layer and the application layer, and when the user uses an application based on the electronic device, the instructions or responses are transmitted from the driver layer to the application layer through the framework layer to realize the operation of the application.

[0056] In an embodiment of the present application, a virtual screen is pre-set on the driver layer, or a virtual screen is set on the framework layer, that is, the virtual screen is located on the data transmission path of the driver layer and the framework layer of the electronic device, and can be applicable to different types of electronic devices; and the virtual screen is located below the application layer; to avoid the problem that some applications declare themselves as top-level windows, resulting in the inability to set a virtual screen thereon, so that the virtual screen can be applicable to applications with different settings, and even if the underlying controls and / or applications of the electronic device are upgraded, it will not affect the use of the virtual screen, controls and various applications, and the versatility and compatibility are both good.

[0057] In a specific implementation, the virtual screen is used to obtain all input operations on the electronic device, such as the coordinate information of the focus, etc., where the focus can be formed by a stylus or by other operating bodies. Optionally, each application can set a different operation mode, and the current mode can be determined based on the coordinate information of the focus. As one example, after obtaining the coordinate point information of the focus, the virtual screen determines whether the coordinate point identified by the coordinate point information falls within the input coordinate range, wherein the input coordinate range is the input coordinate range corresponding to a target application, and the input coordinate ranges corresponding to different target applications are different; when it is determined that the coordinate point identified by the coordinate point information falls within the input coordinate range, it is determined that the target application is in a text input mode; when it is determined that the coordinate point identified by the coordinate point information does not fall within the input coordinate range, it is determined that the target application is in a gesture mode or a drawing mode, etc., and the embodiment of the present application does not specifically limit this, and the current mode of the target application can also be determined based on a pre-set judgment condition, such as the distance and duration of the focus moving on the electronic device, as long as the current mode of the target application can be determined.

[0058] In the case where it is determined that the target application is in the text input mode, the virtual screen is controlled to acquire the input trace in response to the trace input operation of the input device.

[0059] Before the operation control virtual screen obtains the input track, the target input device needs to be further determined. Specifically, the target application generates a request instruction to transmit the request instruction to the framework layer to the driver layer, and the request instruction can also be transmitted to the system bottom layer of the electronic device, that is, the processing layer or the control layer, so that the driver layer or the system bottom layer responds to the request instruction, wherein the request instruction is used to determine the target input device.

[0060] In order to ensure that the target input device can simultaneously satisfy the target application and the system driver layer of the electronic device, the target input device in the embodiment of the present application includes a first input device and a second input device supported by the driver layer; wherein the first input device is one of a hard keyboard, a soft keyboard, and a mouse, and the second input device includes a stylus or a touchpad. For example, when the electronic device is in a non-touch state, any one of the first input devices can be used as the target input device. Of course, multiple first input devices can also be used as target input devices at the same time, such as a hard keyboard and a mouse combined to form a target input device, or a soft keyboard and a mouse combined to form a target input device. When the electronic device is in a touch state, any one of the second input devices can be used as the target input device. For example, when a touch screen is provided on the electronic device, the stylus corresponding to the electronic device can be determined as the target input device.

[0061] In an embodiment of the present application, once the virtual screen acquires the input track, that is, the electronic device is in a touch state, at this time, it is determined that the target input device is the second input device, so that the virtual screen forwards, transmits, etc. the acquired input track as the target input device.

[0062] S102, identifying the input trajectory to obtain trajectory identification information.

[0063] In a specific implementation, after the input trajectory is acquired through the virtual screen, the input trajectory is calculated through a preset trajectory recognition algorithm to obtain trajectory recognition information, that is, text information corresponding to the input trajectory.

[0064] S103, displaying the trajectory recognition information to realize the full-screen handwriting function.

[0065] In a specific implementation, after obtaining the track identification information, the track identification information is displayed through the display device of the electronic device to realize the full-screen handwriting function. Specifically, the track identification information is transmitted to the application layer of the electronic device, and the target application in the application layer is controlled to display the track identification information.

[0066] The implementation method of the embodiment of the present application obtains the input trajectory through a virtual screen set on the data transmission path of the driving layer and the framework layer of the electronic device, and then identifies the input trajectory to obtain trajectory identification information, and realizes the full-screen handwriting function by displaying the trajectory identification information. Compared with the prior art of creating a transparent window on the upper layer of the application layer, the virtual screen of the present application will not affect the functions and upgrades of various applications in the electronic device. It can not only support the electronic device to realize the full-screen handwriting function, but also can be applicable to a variety of electronic devices and a variety of applications on electronic devices, and has good versatility and compatibility.

[0067] like Figure 2 As shown, it is a flowchart of another implementation method provided in an embodiment of the present application, wherein the specific steps include S201-S204.

[0068] S201 , determining that the target application is in gesture mode, and controlling the virtual screen to obtain an input trajectory in response to a trajectory input operation of an input device.

[0069] S202 , reporting the input trajectory to the framework layer through the virtual screen, so that the framework layer determines the target instruction corresponding to the input trajectory based on the corresponding relationship between the trajectory and the instruction.

[0070] S203, the control framework layer transmits the target instruction to the application layer.

[0071] S204, controlling the target application in the application layer to respond to the target instruction.

[0072] In a specific implementation, after executing the above-mentioned mode determination method, for example, it is determined that the coordinate point identified by the coordinate point information does not fall within the input coordinate range. As one example, when it is determined that the coordinate point identified by the coordinate point information does not fall within the input coordinate range, it is further determined whether the target application is in gesture mode or drawing mode, and optionally, it is determined whether the target application is in gesture mode or drawing mode based on the length of the input trajectory or based on whether the user performs other preset operations.

[0073] If it is determined that the target application is in gesture mode, the virtual screen will not forward the input track, that is, it will not perform recognition processing on the input track. After the virtual screen is controlled to obtain the input track in response to the track input operation of the input device, the input track is directly reported to the framework layer through the virtual screen, so that the framework layer determines the target command corresponding to the input track based on the correspondence between the track and the command. Among them, the correspondence between the track and the command is pre-set and stored. For example, if the track is from bottom to top, it corresponds to the command "switch to the next page", and if the track is from left to right, it corresponds to the command "accelerate playback", etc.

[0074] After determining the target instruction corresponding to the input trajectory, the control framework layer transmits the target instruction to the application layer. After determining that the application layer receives the target instruction, the target application in the control application layer responds to the target instruction, so that the user can control the target application through gestures.

[0075] like Figure 3 As shown, it is a flowchart of another implementation method provided in an embodiment of the present application, wherein the specific steps include S301-S303.

[0076] S301 , determining that the target application is in a drawing mode, and controlling a virtual screen to obtain an input trajectory in response to a trajectory input operation of an input device.

[0077] S302: Report the input track to the framework layer through the virtual screen, so that the framework layer transmits the input track to the application layer.

[0078] S303, controlling the target application in the application layer to display the input track.

[0079] Similarly, after executing the above-mentioned mode determination method, if it is determined that the target application is in the drawing mode, the virtual screen will not forward the input trajectory, that is, it will not perform recognition processing on the input trajectory. After the virtual screen is controlled to obtain the input trajectory in response to the trajectory input operation of the input device, the input trajectory is directly reported to the framework layer through the virtual screen, so that the framework layer transmits the input trajectory directly to the application layer. In other words, the framework layer does not perform any processing on the input trajectory, but only reports it directly.

[0080] After determining that the application layer receives the input track, the target application in the application layer is controlled to display the input track, so that the user can achieve the purpose of drawing through touch operation.

[0081] Based on the same concept, the second aspect of the present application also provides an electronic device corresponding to a full-screen handwriting implementation method. Since the principle of solving the problem by the electronic device in the present application is similar to the above-mentioned full-screen handwriting implementation method of the present application, the implementation of the electronic device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0082] Figure 4 A schematic diagram of an electronic device provided in an embodiment of the present application is shown, specifically comprising:

[0083] The virtual screen 401 is located on the data transmission path between the driving layer and the framework layer of the electronic device;

[0087] In yet another embodiment, the virtual screen 401 is disposed on the driving layer or the framework layer.

[0088] In yet another embodiment, the control module 402 is further configured to:

[0089] When it is determined that the target application is in a text input mode, the target application determines a target input device; the target input device includes a first input device and a second input device supported by the driver layer,

[0090] When the virtual screen acquires the input track, it is determined that the target input device is the second input device.

[0091] In yet another embodiment, the first input device includes one of a hard keyboard, a soft keyboard, and a mouse, and the second input device includes a stylus pen or a touch pad.

[0097] Reporting the input trajectory to the framework layer through the virtual screen, so that the framework layer determines the target instruction corresponding to the input trajectory based on the correspondence between the trajectory and the instruction;

[0098] Controlling the framework layer to transmit the target instruction to the application layer;

[0099] The target application in the application layer is controlled to respond to the target instruction.

[0100] In yet another embodiment, the electronic device further includes a second display module 406, which is configured to:

[0101] Determining that the target application is in a drawing mode, and controlling a virtual screen to acquire the input trajectory in response to a trajectory input operation of the input device;

[0102] Reporting the input track to the framework layer through the virtual screen, so that the framework layer transmits the input track to the application layer;

[0103] The target application in the application layer is controlled to display the input trace.

[0104] Figure 5 A schematic diagram of the structure of an electronic device as an example is shown. Figure 5 As shown, the electronic device is connected to the stylus, which can be connected by wire or by wireless connection, as long as the electronic device can authenticate, identify and respond to the stylus. Further, the electronic device includes a driver layer, a virtual screen, a framework layer and an application layer, wherein the virtual screen is located between the driver layer and the framework layer, and the application layer is located above the driver layer, the virtual screen and the framework layer. As shown in the figure, the framework layer includes a first determination module, a second determination module and an identification module, and the application layer includes a target application and other applications.

[0105] based on Figure 5 The structure shown executes the above implementation method as follows:

[0106] The framework layer obtains the focus coordinates in the electronic device screen in advance, and determines the mode of the target application based on the focus coordinates through the first determination module. The specific determination method is as mentioned above.

[0107] After determining that the target application is in text input mode, the target input device is further determined by a second determination module. Specifically, after determining that the target application is in text input mode, the target application generates a request instruction and transmits the request instruction to the second determination module, and at the same time transmits its corresponding input device to the second determination module.

[0108] After receiving the request instruction, the second determination module obtains the input devices supported by the driver layer, and determines the target input device based on the input devices supported by the driver layer and the input devices corresponding to the target application. After determining that the target application is in text input mode, once the virtual screen obtains the input track, the stylus is determined as the target input device, and then the virtual screen is controlled to obtain the input track.

[0109] After the virtual screen obtains the input track, it forwards the input track to the recognition module of the framework layer, so that the recognition module calculates the input track through the preset track recognition algorithm to obtain track recognition information, that is, the text information corresponding to the input track. After that, the recognition module transmits the track recognition information to the target application of the application layer.

[0110] After receiving the trajectory recognition information, the target application displays the trajectory recognition information, thereby realizing the full-screen handwriting function.

[0111] When the target application is in gesture mode and drawing mode, it will not be described here, and you can refer to the above.

[0112] The implementation method of the embodiment of the present application obtains the input trajectory through a virtual screen set on the data transmission path of the driving layer and the framework layer of the electronic device, and then identifies the input trajectory to obtain trajectory identification information, and realizes the full-screen handwriting function by displaying the trajectory identification information. Compared with the prior art of creating a transparent window on the upper layer of the application layer, the virtual screen of the present application will not affect the functions and upgrades of various applications in the electronic device. It can not only support the electronic device to realize the full-screen handwriting function, but also can be applicable to a variety of electronic devices and a variety of applications on electronic devices, and has good versatility and compatibility.
