Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a writing method for an interactive smart device, it should be noted that the steps illustrated in the flowchart of the accompanying drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
FIG. 1 is a flow chart of a writing method of an interactive smart device according to an embodiment of the present invention.
The handwriting erasing method provided by this embodiment may be executed by a writing display device, where the writing display device may be implemented in a software and/or hardware manner, and the writing display device may be formed by two or more physical entities, or may be formed by one physical entity. The writing display device can be a computer, a mobile phone, a tablet, a projector or an interactive smart tablet and the like. In an embodiment, an interactive smart tablet is described as an example of a writing display device, where the interactive smart tablet may be an integrated device that controls content displayed on a display tablet and implements human-computer interaction operations through a touch technology, and integrates one or more functions of a projector, an electronic whiteboard, a curtain, a sound, a television, a video conference terminal, and the like.
In an embodiment, the interactive smart tablet establishes a data connection with at least one external device. Among these, external devices include, but are not limited to: mobile phones, notebook computers, USB flash disks, tablet computers, desktop computers, and the like.
The embodiment of the communication mode of the data connection between the external device and the interactive intelligent tablet is not limited, and the communication mode can be a USB connection mode, an internet mode, a local area network mode, a Bluetooth mode, a Wi-Fi mode or a ZigBee mode and the like.
Further, the interactive smart tablet has a touch screen, and the touch screen may be a touch screen capable of implementing a single touch function, for example: capacitive touch screen, electromagnetic touch screen, can also be the touch-sensitive screen that can realize capacitive sensing, electromagnetic induction and infrared induction simultaneously. When a user touches the touch screen of the interactive intelligent panel through a finger, the capacitance parameter of the touch position changes, and the touch frame determines the touch position of the finger on the touch screen according to the change of the capacitance; or when the finger contacts the touch frame, the infrared receiving end is blocked to receive the infrared signal, and the touch frame determines the touch position of the finger according to the blocked infrared signal; or when the user releases the touch screen by using the electromagnetic pen, the position of the electromagnetic pen contacted with the touch screen is subjected to electromagnetic induction, so that the change of magnetic flux is generated, and the position of the electromagnetic pen contacted with the touch screen is determined by the electromagnetic screen of the touch frame according to the change of the magnetic flux.
Optionally, the interactive smart tablet is installed with whiteboard application software, where the whiteboard application software may be installed in the interactive smart tablet in advance, or may be downloaded from a third-party device or a server and installed with writing application software for use when the interactive smart tablet is started. The third-party device is not limited in the embodiment. Specifically, the whiteboard application software is used for acquiring the operation of a finger or an electromagnetic pen of a user in a writing interface, acquiring a plurality of control points according to the operation of the user, and generating the writing handwriting of the user according to the control points. The interactive intelligent tablet further displays the generated handwriting on the display screen, and parameters such as color, thickness and the like of the handwriting displayed on the display screen can be defaulted by the whiteboard application software or can be selected by a user through the functional control before writing.
As shown in fig. 1, the method comprises the steps of:
in step S102, a plurality of writing areas are generated.
After the interactive intelligent equipment starts a split screen writing function, a plurality of independent writing areas are generated. Specifically, the writing area is generated on the display interface and used for receiving the writing event and generating a corresponding writing track. The multiple independent writing areas may be of the same size or of different sizes. Each writing area can realize independent writing function, and multiple writing areas are not related.
FIG. 2 is a schematic diagram of an alternative interactive smart device split-screen writing interface according to an embodiment of the present invention. Referring to fig. 2, the example divides the writing area of the interactive intelligent device into two identical parts, each part is an independent writing area, and the writing track can be independently displayed.
Specifically, each of the writing areas may include: identification information of the border and/or writing area.
The frame of the writing area indicates the boundary of the writing area, and the mark of the writing area may be information such as the name and ID of the writing area.
In an alternative embodiment, still referring to fig. 2, the interactive intelligent device divides two writing areas, where both writing areas have respective borders, and the identification information of the two writing areas is writing area 1 and writing area 2, respectively.
Step S102 specifically includes the following steps:
in step S1021, a plurality of writing processes are generated.
Specifically, one writing process corresponds to one writing area and is used for processing writing events of the corresponding writing area, so that mutual independence among a plurality of writing areas is realized.
In step S1023, a corresponding writing area is allocated for each writing process.
In the scheme, the interactive intelligent device generates a plurality of writing processes and allocates a corresponding writing area for each writing process. At run-time, each writing area has a corresponding window, and the received writing events are processed independently through respective writing processes.
In step S104, a touch event is received.
Specifically, the touch event may be a touch event generated by a user operating the interactive smart device. For example, a user writes on a screen of the interactive smart device using an electromagnetic pen, or the user operates on the screen of the interactive smart device with a finger.
Step S106, detecting whether the received touch event is a writing event, wherein the writing event is a touch event of a preset type.
Specifically, the writing event is a touch event for generating a writing trace in the writing area.
In an alternative embodiment, the touch event type may be determined according to the device generating the touch event, for example: the touch event generated by the electromagnetic pen is of one type, and the touch event generated by the touch of a finger is of another type; in another alternative embodiment, the type of touch event may also be determined from the touch data of the touch event, for example: the electromagnetic touch data, the capacitive touch data and the infrared touch data are respectively different touch types.
In the above solution, the predetermined type of touch event may be an electromagnetic touch event, i.e. a touch event generated by an electromagnetic pen. In this embodiment, when receiving a touch event, the interactive intelligent device determines whether the touch event is a predetermined type of touch event, and the following two determination results are respectively described.
In step S108, when the received touch event is a writing event, a writing trace corresponding to the writing event is generated.
In the above solution, the predetermined type of touch event may be an electromagnetic touch event, i.e. a touch event generated by an electromagnetic pen. In this embodiment, the writing trace is generated from the writing event only when the touch event is the writing event. Further, the writing event may be a predetermined type of touch event with a certain writing procedure (e.g., down- > move- > … move- > up). One writing event received by the interactive intelligent device can be generated in any one writing area, and the received multiple writing events can be simultaneously received writing events generated in different writing areas.
It should be noted that, in the above steps, the writing event is directly distributed to the writing process by the touch frame of the interactive smart device, and is not distributed through the Android system of the interactive smart tablet, so that the normal display logic of the Android system is not affected. The method can not intercept other types of touch events, and can save the GPU utilization rate due to the fact that a normal drawing process of Android is not utilized.
It should be noted that the plurality of writing areas cannot be bounded by a surface view, so as to avoid the view of the writing area intercepting normal Android events (i.e. non-predetermined types of touch events).
In an alternative embodiment, and as further illustrated in conjunction with FIG. 2, the writing area of the interactive smart tablet is divided into two separate writing areas. When a user A writes in the writing area 1, the writing area 1 displays the writing track of the user A; meanwhile, the user B can write in the writing area 2, and the writing area 2 displays the writing trace of the user B. It should be noted that, in this example, the interactive smart device has two writing areas, so that two writing events can be received at the same time, and for the interactive smart device with more writing areas, more writing events can be received at the same time.
In order to implement the scheme, the split-screen writing application of the interactive intelligent device respectively creates writing processes for a plurality of writing areas, each writing area has a corresponding window when the interactive intelligent device runs, each window is displayed in the corresponding writing area, the interactive intelligent device detects an area generated by a writing event, and distributes the writing event to the corresponding writing process according to the area generated by the writing event.
Step S108 specifically includes the following steps:
step S1081, detecting a writing area to which the received writing event belongs.
Specifically, the area to which the writing event is received may be a writing area in which a first point (down) in the writing event is located. For example, if a writing event is in a first writing area at a first point on the interactive smart tablet, the writing area continues to detect other control points of the writing event, and other writing areas do not detect the first point of the writing event and do not detect other control points of the writing event.
And step S1083, sending the received writing event to the writing process corresponding to the writing area.
In an alternative embodiment, as shown in fig. 2, this example includes two writing areas, writing area 1 and writing area 2, each having a corresponding writing process. When a user writes in the writing area 1, the interactive intelligent device distributes the writing event of the user to the writing process corresponding to the writing area 1, and therefore the writing track corresponding to the writing event can be displayed in the display area of the writing area 1.
And step S1085, drawing a writing track corresponding to the writing event in the writing area receiving the writing event through the writing process.
The above steps are used to enable the trajectory corresponding to the writing event to be displayed in the generated writing area.
In an optional embodiment, after the interactive intelligent device detects the writing event, the interactive intelligent device directly distributes the writing event to the writing process corresponding to each writing area, so as to draw the writing track corresponding to the writing event.
As can be seen from the above, in the above embodiments of the present application, the interactive intelligent device receives a writing event, the interactive intelligent device displays a plurality of writing areas, the interactive intelligent device receives the writing event, and the interactive intelligent device displays a writing track corresponding to the writing event in the writing area generated by the writing event. According to the scheme, the plurality of regions are arranged, and the writing tracks corresponding to the writing events are displayed in the writing regions generated by the writing events, so that the technical problem that in the prior art, when any user writes in the writing regions, other users cannot operate the function control in the multi-screen writing scene of the interactive intelligent device is solved.
Step S1010, in a case that the detected touch event is not a writing event, distributing the touch event to a split screen writing application.
In the step S1010, if the touch event is not a predetermined type of touch event, it indicates that the current touch event is not a writing event, and the interactive intelligent device distributes the touch event to a system (for example, an Android system), and the system distributes the touch event to a corresponding application.
When a plurality of writing windows of the split-screen writing application are tiled on a display interface of the interactive intelligent device, the application on the uppermost layer is a tool bar of the split-screen writing application, so that the system distributes the touch event to the split-screen writing application, the split-screen writing application executes a function control in the tool bar triggered by the touch event, and if the touch event does not trigger any function control, the touch event is not responded.
Therefore, in the above scheme, taking a predetermined type of touch event as an electromagnetic touch event as an example, the obtained effect may be that while the user uses the electromagnetic pen to write in the writing area, other users may use fingers to trigger the function control.
As can be seen from the above, in the above embodiments of the present application, the interactive intelligent device receives a start signal, where the start signal is used to start a split-screen writing application of the interactive intelligent device; the interactive intelligent equipment generates a plurality of writing areas; the interactive intelligent equipment receives a touch event; the method comprises the steps that the interactive intelligent equipment detects whether a received touch event is a writing event, wherein the writing event is a touch event of a preset type; generating a writing track corresponding to the writing event under the condition that the received touch event is the writing event; and in the case that the received touch event is not a writing event, prohibiting generation of a writing track, and distributing the touch event to the split screen writing application. According to the scheme, in the split-screen writing application of the interactive intelligent device, the type of the received touch event is judged, and whether the received touch event is used for writing or controlling is determined, so that when a plurality of users use the split-screen writing function at the same time, any user can write through the touch event of the preset type, and other users can use the touch event of the non-preset type to operate the control, and the technical problem that in the prior art, the interactive intelligent device cannot operate the function control when any user writes in a writing area in a multi-screen writing scene is solved.
Example 2
According to an embodiment of the present invention, there is further provided an embodiment of a writing method of an interactive intelligent device, where the method is to explain the writing method of the interactive intelligent device in embodiment 1 more specifically, and fig. 3 is a flowchart of a writing method of an interactive intelligent device according to embodiment 2 of the present application, and with reference to fig. 3, the method includes:
and step S31, receiving a starting signal, wherein the starting signal enables a user to start a split screen writing application of the interactive intelligent device.
Specifically, the split-screen writing application of the interactive intelligent device provides a split-screen writing function for the interactive intelligent device, and is used for generating a plurality of writing areas on a display interface of the interactive intelligent device. The plurality of writing areas are mutually independent and can independently execute writing commands.
The split screen writing application provides a writing function for triggering the interactive intelligent device to generate a plurality of writing areas, and the steps S31 to S37 are continuously executed.
In an alternative embodiment, the interactive intelligent device provides a control of the split-screen writing application on the main interface, the user triggers the control of the split-screen writing application, and the interactive intelligent device receives the starting signal and starts the split-screen writing application.
In step S33, a plurality of writing areas are generated.
In step S35, a touch event is received.
In step S37, it is detected whether the received touch event is a writing event, wherein the writing event is a touch event of a predetermined type.
In step S39, when the received touch event is a writing event, a writing trace corresponding to the writing event is generated.
In step S311, in the case that the received touch event is not a writing event, the touch event is distributed to the split screen writing application.
Step 313, each writing area comprises a function control corresponding to each writing area, and whether the touch event is a control selection event is detected under the condition that the received touch event is not a writing event, wherein the control selection event is used for triggering the function control of the writing area.
Specifically, the functional control may include a control commonly used in writing, for example: handwriting color, handwriting thickness, eraser, etc. Each writing area can display a plurality of function controls, and the plurality of function controls of each writing area can form a set and are displayed at a preset position of the writing area in the form of a floating window. In the area where the floating window is located, the floating window is the uppermost layer, so that if the position of the touch event is the position of any functional control in the floating window, the touch event can trigger the functional control corresponding to the position of the touch event, and at this time, the touch event is a control selection event. Still referring to FIG. 2 as an example, in this example, the functionality controls of each writing area constitute a toolbar that is displayed below each writing area.
The function selection event is generated by triggering a function control, each writing area having an associated function control for controlling the writing area corresponding thereto. When a user triggers a function control, the interactive intelligent device receives a control selection event, for example, if the triggered function control is screen clearing, the writing area corresponding to the triggered function control is screen clearing.
In an alternative embodiment, and still referring to fig. 2, the function control in the toolbar of writing area 1 is only used to control the writing progress of writing area 1, and the function control in the toolbar of writing area 2 is also only used to control the writing progress of writing area 2.
In an alternative embodiment, the control selection event and the writing event are different types of touch events, for example, the writing event may be an electromagnetic touch event and the control selection event may be an infrared/capacitive touch event. When the infrared/capacitance touch event is generated at the position of the function control, the infrared/capacitance touch event is a control selection event capable of triggering the function control.
And step S315, if the touch event is a control selection event, the writing area responds to a functional control triggered by the control selection event. Additionally, if the touch event does not select an event for the control, the touch event is not responded to.
In an alternative embodiment, when the touch event is generated at the position of the function control, an event is selected for the control capable of triggering the function control, and therefore, the writing area where the position of the touch event is generated responds to the function control triggered by the touch event; when the position generated by the touch event cannot trigger the function control, the touch event does not select an event for the control, and the writing area does not respond to the touch event.
Therefore, in the above scheme, taking the predetermined type of touch event as an electromagnetic touch event as an example, the obtained effect is that the user writes in the writing area by using an electromagnetic pen and can trigger the function control by using a finger. Further, when one of the writing areas is receiving a writing event, the other writing area is not affected to receive a control selection event, i.e. when the user writes in one of the writing areas, the function controls of the other writing areas can be triggered.
Fig. 4 is a flowchart of screen-division writing of an interactive smart device according to embodiment 2 of the present invention, which is described in detail below with reference to fig. 4.
S41: the split screen writing application is started.
Specifically, after the interactive intelligent device starts the split-screen writing application, the split-screen writing interface shown in fig. 2 is obtained. The interface includes writing area 1, writing area 2, and tool bars corresponding to writing area 1 and writing area 2, respectively.
S42: generating electromagnetic/infrared/capacitive touch events.
Specifically, the device for generating the touch event may further include all hardware devices such as a mouse and a roller ball that can generate the touch event.
S43: it is determined whether the touch event is a predetermined type of touch event. If the determination result is yes, the process proceeds to step S44, otherwise, the process proceeds to step S46.
In the above step S43, the type of each touch event may be determined according to the device that generated the touch event. If the event generated by the electromagnetic pen is taken as a predetermined type of touch event, the touch event generated by the electromagnetic pen can be directly distributed to the split screen writing application, while other types of touch events are distributed through a normal system event processing flow.
S44: and distributing the event to the corresponding writing area according to the area generated by the touch event.
The split screen writing application distributes the whole event stream to the writing process of the writing area according to which writing area the position generated by the touch event (for example, the coordinates of the electromagnetic pen down event) belongs to. A second stream of writing events may be generated at the same time as the first stream of writing events is generated, and the location where the second stream of writing events is generated belongs to another writing area, then the second stream of writing events is distributed to the writing progress of the other writing area, so that writing area 1 and writing area 2 may respond to writing events at the same time.
S45: and drawing and displaying a writing track.
The writing area draws a writing track according to the received event stream (down- > move- > … move- > up) (for example, draws the writing track according to the control points of the event stream through a Bezier curve), and then displays the drawn handwriting to the corresponding writing area.
S46: touch events are distributed normally through the system.
The system distributes the touch event to the control at the corresponding position of the writing software. If the touch event has coordinates of (100, 200), the system will distribute the touch event to the control according to the control at coordinates x 100 and y 200 of the software that acquired the touch event, and the control will respond to the touch event and generate the corresponding action.
S47: the toolbar of the writing area responds to the event and generates a corresponding operation.
And if the function of the function control is screen clearing, the written content of the corresponding writing area can be cleared.
S48: and exiting the writing software.

a first generating module 52 for generating a plurality of writing areas.
After the interactive intelligent equipment starts a split screen writing function, a plurality of independent writing areas are generated through the first generation module. Specifically, the writing area is generated on the display interface and used for receiving the writing event and generating a corresponding writing track. The multiple independent writing areas may be of the same size or of different sizes. Each writing area can realize independent writing function, and multiple writing areas are not related.

Specifically, the touch event may be a touch event generated by a user operating the interactive smart device. For example, a user writes on a screen of the interactive smart device using an electromagnetic pen, or the user operates on the screen of the interactive smart device with a finger.
A detecting module 56, configured to detect whether the received touch event is a writing event, where the writing event is a predetermined type of touch event.
Specifically, the writing event is a touch event for generating a writing trace in the writing area. The interactive intelligent device detects whether the touch event is a writing event by judging whether the received touch event is a touch event of a predetermined type.
In an alternative embodiment, the touch event type may be determined according to the device generating the touch event, for example: the touch event generated by the electromagnetic pen is of one type, and the touch event generated by the touch of a finger is of another type; in another alternative embodiment, the type of touch event may also be determined from the touch data of the touch event, for example: the electromagnetic touch data, the capacitive touch data and the infrared touch data are respectively different touch types.
And a second generating module 58, configured to generate a writing track corresponding to the writing event if the received touch event is the writing event.
In the above solution, the predetermined type of touch event may be an electromagnetic touch event, i.e. a touch event generated by an electromagnetic pen. In this embodiment, the writing trace is generated from the writing event only when the touch event is the writing event. Further, the writing event may be a predetermined type of touch event with a certain writing procedure (e.g., down- > move- > … move- > up). One writing event received by the interactive intelligent device can be generated in any one writing area, and the received multiple writing events can be simultaneously received writing events generated in different writing areas.
It should be noted that, in the above steps, the writing event is directly distributed to the writing process by the touch frame of the interactive smart device, and is not distributed through the Android system of the interactive smart tablet, so that the normal display logic of the Android system is not affected. The method can not intercept other types of touch events, and can save the GPU utilization rate due to the fact that a normal drawing process of Android is not utilized.
It should be noted that the plurality of writing areas cannot be bounded by a surface view, so as to avoid the view of the writing area intercepting normal Android events (i.e. non-predetermined types of touch events).
A distributing module 510, configured to distribute the touch event to the split-screen writing application if the received touch event is not a writing event.
In the above scheme, if the touch event is not a predetermined type of touch event, it indicates that the current touch event is not a writing event, the interactive intelligent device distributes the touch event to a system (for example, an Android system), and the system distributes the touch event to a corresponding application.
When a plurality of writing windows of the split-screen writing application are tiled on a display interface of the interactive intelligent device, the application on the uppermost layer is a tool bar of the split-screen writing application, so that the system distributes the touch event to the split-screen writing application, the split-screen writing application executes a function control in the tool bar triggered by the touch event, and if the touch event does not trigger any function control, the touch event is not responded.
Therefore, in the above scheme, taking a predetermined type of touch event as an electromagnetic touch event as an example, the obtained effect may be that while the user uses the electromagnetic pen to write in the writing area, other users may use fingers to trigger the function control.
Optionally, according to the foregoing embodiment of the present application, each writing area includes a function control corresponding to each writing area, and the distribution module includes:
and the detection submodule is used for detecting whether the touch event is a control selection event, wherein the control selection event is used for triggering the functional control of the writing area.
Specifically, the functional control may include a control commonly used in writing, for example: handwriting color, handwriting thickness, eraser, etc. Each writing area can display a plurality of function controls, and the plurality of function controls of each writing area can form a set and are displayed at a preset position of the writing area in the form of a floating window. In the area where the floating window is located, the floating window is the uppermost layer, so that if the position of the touch event is the position of any functional control in the floating window, the touch event can trigger the functional control corresponding to the position of the touch event, and at this time, the touch event is a control selection event.
And the response sub-module is used for responding the functional control triggered by the control selection event in the writing area if the touch event is the control selection event.
In an alternative embodiment, when the touch event is generated at the position of the function control, an event is selected for the control capable of triggering the function control, and therefore, the writing area where the position of the touch event is generated responds to the function control triggered by the touch event; when the position generated by the touch event cannot trigger the function control, the touch event does not select an event for the control, and the writing area does not respond to the touch event.
Optionally, according to the above embodiment of the present application, the first generating module includes:
and the generation submodule is used for generating a plurality of writing processes by the interactive intelligent equipment.
Specifically, one writing process corresponds to one writing area and is used for processing writing events of the corresponding writing area, so that mutual independence among a plurality of writing areas is realized.
And the distribution submodule is used for distributing the corresponding writing area for each writing process by the interactive intelligent equipment.
In the scheme, the interactive intelligent device generates a plurality of writing processes and allocates a corresponding writing area for each writing process. At run-time, each writing area has a corresponding window, and the received writing events are processed independently through respective writing processes.
Optionally, according to the foregoing embodiment of the present application, the second generating module includes:
and the detection unit is used for detecting the writing area to which the received writing event belongs.
Specifically, the area to which the writing event is received may be a writing area in which a first point (down) in the writing event is located. For example, if a writing event is in a first writing area at a first point on the interactive smart tablet, the writing area continues to detect other control points of the writing event, and other writing areas do not detect the first point of the writing event and do not detect other control points of the writing event.
And the sending submodule is used for sending the received writing event to the writing process corresponding to the writing area.
In an alternative embodiment, as shown in fig. 2, this example includes two writing areas, writing area 1 and writing area 2, each having a corresponding writing process. When a user writes in the writing area 1, the interactive intelligent device distributes the writing event of the user to the writing process corresponding to the writing area 1, and therefore the writing track corresponding to the writing event can be displayed in the display area of the writing area 1.
And the drawing submodule is used for drawing a writing track corresponding to the writing event in the writing area receiving the writing event through the writing process.
Specifically, the interactive intelligent device displays the track corresponding to the writing event in the generated writing area through the drawing submodule.
Optionally, according to the above embodiment of the present application, the plurality of writing areas include: identification information of the border and/or the plurality of writing areas.
The frame of the writing area indicates the boundary of the writing area, and the mark of the writing area may be information such as the name and ID of the writing area.
In an alternative embodiment, still referring to fig. 2, the interactive intelligent device divides two writing areas, where both writing areas have respective borders, and the identification information of the two writing areas is writing area 1 and writing area 2, respectively.
Optionally, according to the above embodiment of the present application, the apparatus further includes: the receiving submodule is used for receiving a starting signal before generating a plurality of writing areas, wherein the starting signal is used for starting a split screen writing application of the interactive intelligent device.
