On the basis of a system layer, an application program developed for meeting different fields and different problems of a user is installed in the interactive flat plate, and the corresponding architecture level is an application layer. In the description of the embodiment of the present invention, the interactive tablet may be installed with at least one application having a writing function. The application program with the writing function may be an application program carried by an operating system, and may also be an application program downloaded from a third-party device or a server. Optionally, the application program has other editing functions besides the writing function based on the touch operation, such as a deleting function, a table inserting function, a picture inserting function, a table drawing function, a picture drawing function, and the like.

The graphical interface displayed in the display screen of the interactive tablet is also a touch detection area for detecting user operation, namely the ranges of the graphical interface and the touch detection area are basically overlapped.

The interface refers to an interactive interface for receiving and/or displaying information by an application program, such as an application of a video playing class, wherein the interactive interface is mainly used for displaying a changed video picture; the real-time communication type application, wherein the interactive interface is mainly used for receiving the content input by a near-end user and displaying the content input by a far-end user; the interactive interface of the file editing application is mainly used for receiving and displaying the content input by the user; the interactive interface of the browser-type application is mainly used for receiving keywords input by a user and displaying webpage content obtained based on the keywords.

In describing the implementation process of the present scheme, a user interface presented in the use process of the whiteboard application, that is, a control operation or a writing operation performed in the interface of the whiteboard application, is mainly taken as an example for explanation. As mentioned above, the whiteboard application refers to an application for a user to perform operations such as writing and displaying, and may be used to generate writing handwriting according to the writing operation of the user on an interface of the whiteboard application, and may also be used to insert and display multimedia elements on the interface of the whiteboard application, where the multimedia elements may include graphics, images, forms, documents, audio files, and/or video files.

More specific interaction related operations can be realized by single click, long press, sliding, multiple clicks and the like of a single point, can also be realized by simultaneous sliding, clicking, long press, rotating and the like of multiple points, and can also be realized by the distance change trend among the multiple points, and the operations are mainly used for realizing control operations. And the change of the essential content in the interface of the whiteboard application is mainly realized by writing operation.

When the touch detection area is used for touch operation, for example, when a writing pen or a finger is used for touching a display screen with a touch function for writing, a touch sensing module of the display screen can sense the change of infrared light, the change of current, the change of voltage, the change of magnetic flux or the change of pressure (corresponding to the specific setting type of the infrared display screen, the capacitive display screen, the resistive display screen, the electromagnetic display screen or the pressure-sensitive display screen), so that a touch signal containing the coordinates of a touch position and the trigger time of the touch signal are obtained after conversion, the track data of the writing track input in the process of writing until the writing is stopped by lifting can be obtained by the writing pen or the finger of the user through pressing each time according to the coordinates of the touch position and the trigger time of the touch signal, and the writing track input by the user is displayed on the graphical interface of the display screen in real time according to the track data. Of course, the writing process is not limited to writing, and any entry process implemented on the display screen of the interactive tablet for displaying the operation track can be regarded as the writing process. In addition, according to different display elements of the occurrence positions of the touch operations, the touch operations can respond to operations such as clicking, dragging and the like of the user. The way in which these different responses are processed at the bottom level is the same. Based on the hardware realization of basic functions such as touch and display, various interactive display designs of the interactive flat panel can be realized. It should be noted that, from the experience of user interaction, the display interface and the touch detection area of the interactive tablet are generally the same interface, and for the notebook computer, the display interface and the touch detection area may be completely independent from each other, or may be partially independent and partially overlapped.

In practical use, the image data is displayed on the display screen of the interactive flat panel, when a user clicks the content displayed on the display screen through a touch object such as a finger or a touch pen, for example, a graphical button displayed on the display screen, the touch component of the interactive flat panel acquires touch data, so that the touch component converts the touch data into coordinate data of a touch point and then sends the coordinate data to the complete machine module, or the touch data is sent to the complete machine module and converted into coordinate data of the touch point by the complete machine module, and the complete machine module obtains the coordinate data of the touch point and then sends the coordinate data to a corresponding program to realize corresponding control operation, so that the display content of the display screen is driven to change, and diversified display and operation effects are realized.

Touch components are distinguished from technical principles and can be divided into five basic categories; a vector pressure sensing technology touch component, a resistance technology touch component, a capacitance technology touch component, an electromagnetic technology touch screen, an infrared technology touch component and a surface acoustic wave technology touch component. According to the working principle of the touch assembly and the medium for transmitting information, the touch assembly can be divided into four categories: resistive, capacitive, electromagnetic, infrared, and surface acoustic wave.

In the embodiment of the application, the interactive flat panel is equivalent to a display screen with a complete machine module and a touch function, the complete machine module is a built-in module of the interactive flat panel and does not comprise a main control module, a low-performance Android system runs in the complete machine module, and the complete machine module mainly achieves the display processing and touch data processing functions of the interactive flat panel. The hardware configuration of the whole machine module is low, and the installation of other application software is not supported except for the configuration of an operating system and basic processing software (such as whiteboard writing software and annotation application software). If the interactive tablet needs to implement other functions, the interactive tablet needs to be accessed to the main control module, and corresponding functions are implemented by installing relevant application software on the main control module, for example, if a file needs to be displayed, relevant display software needs to be installed on the main control module, if a video conference function needs to be implemented, video conference software needs to be installed on the main control module, and the like. The main control module is an Open Plug Specification (OPS) module on the interactive tablet, and application software running on the interactive tablet is installed on the main control module. The main control module may be an operating system such as Windows and high-performance Android, for example, the main control module may be a PC module and a high-performance Android module, which may be understood as a computer.
