This invention discloses a control method, device, and intelligent interactive whiteboard application. The whiteboard application includes a selection box component, a canvas, and a parent component. The interface of the whiteboard application includes multiple display elements and a first selection box for selecting multiple display elements. The method includes: when the selection box component detects a preset operation event generated within the first selection box, sending the event attribute information of the preset operation event to the parent component; the parent component determining, based on position information, whether the preset operation event is used to select display elements within the first selection box; and, if it is determined that the preset operation event is used to select display elements within the first selection box, selecting the target display element selected by the preset operation event. This invention solves the technical problem in the prior art where, when multiple handwritings are selected, it is impossible to directly select from the already selected handwritings.

Interactive whiteboard for education

This invention relates to the field of interactive whiteboard technology and discloses a touch control method for turning an interactive whiteboard on and off. By clicking the "Create New Touch Switch Area" button on the interactive whiteboard, the coordinates required to create the touch switch area are saved to the driver. Then, by sequentially selecting "Set Touch Switch Area" and "Add Touch Switch Area," the coordinates of the set touch switches are modified and adjusted. A PCB is set inside the interactive whiteboard, consisting of two sets of horizontal (Y-axis) and vertical (X-axis) intersecting wires. This touch control method for turning the interactive whiteboard on and off allows users to select the touch control method to turn off the whiteboard through touch settings, making it more convenient for users. When using the whiteboard, if certain operations are needed, such as writing, the touch control method can be turned off to achieve the operation, minimizing the impact on the screen.

The invention provides a writing method, an interactive panel and a storage medium, and the method comprises the steps: displaying a writing layer on an interface in an overlapping manner when it is confirmed that a moving operation is executed by a preset touch object. And when the text edit box obtaining the input focus exists or the moving slave operation points to a certain text edit box, displaying a toolbar at a preset position of the text edit box. After it is confirmed that the moving operation is terminated, text content corresponding to the moving operation is displayed in the text editing box, and the writing layer is closed. And when an operation on a certain text editing control in the toolbar is received, editing the text content according to an editing mode corresponding to the text editing control. According to the method and the device, the text content can be edited through the text editing control in the toolbar, so that the text content can be edited without calling a soft keyboard, the editing process of the text content can be simplified, and the input efficiency of the text content can be improved.

This invention provides a human-computer interaction method, device, interactive tablet, and storage medium. The method includes: driving an infrared transmitter to emit infrared signals on the surface of a display screen, driving an infrared receiver to receive the infrared signals on the surface of the display screen, determining that the intensity of a portion of the infrared signal in the current frame decreases relative to a reference range, determining that the intensity of a portion of the infrared signal in the current frame increases relative to the reference range, responding to the current frame infrared signal, and performing a touch operation. This embodiment distinguishes whether a touch object touches the surface of the display screen and whether a touch operation is responded to based on the rise and fall of the infrared signal, adapting to the needs of business scenarios and thus improving the performance of touch operation in the business scenario. In writing scenarios, it can solve the problem of zero-height writing.

This utility model discloses a central control integration device for a dual-system intelligent interactive whiteboard all-in-one machine, including a body, an outer frame, and a connecting component that maintains the relative position of the body and the outer frame. A through-wire is fixedly connected to the bottom of the outer frame. In this application, after the base frame and the bottom of the through-wire are fixed by a fastening rod, the plug on the wire harness is passed through the through-wire and the frame, and then the plug is connected to the corresponding interface on the bottom of the body. The clearance space between the body and the through-wire ensures stable and convenient installation of the plug. Then, the push rod is rotated to make it screw into the frame. The push rod pushes the positioning strip to slide along the slot until the positioning strip is close to the outer wall of the wire harness, thereby achieving local positioning of the wire harness. When the outer part of the wire harness generates traction due to pulling or shaking, the force will act on the connection between the wire harness and the positioning strip, thereby further ensuring the stability of the central control integration device.

The utility model belongs to the technical field of teaching interactive whiteboard supports, and particularly relates to a foldable interactive whiteboard auxiliary support which comprises shaft seats, supporting plates and supporting legs, the supporting plates and the supporting legs are hinged to the shaft seats at the same time, the shaft seats, the supporting plates and the supporting legs are symmetrically arranged in two groups, supporting rods located between the supporting plates and the supporting legs are fixed to the bottoms of the shaft seats, and the supporting rods are fixed to the bottoms of the shaft seats. Vertically sliding adapting seats are arranged in the supporting rods, the adapting seats are movably connected with the supporting plates and the supporting legs through hinged connecting rods, the supporting rods and the supporting plates can be unfolded or folded at the same time through lifting of the adapting seats, and folding rods are hinged to the upper end and the lower end between the two supporting plates; it can be understood that one-key synchronous opening and closing of the supporting plates and the supporting legs are achieved through linkage of the adapting bases, the connecting rods and the locking blocks, and the folding rods between the two supporting plates can be folded twice to compress the size; the modularized backup plate and the supporting plate are designed in an inserted mode, the overall rigidity is enhanced during installation, the supporting plate is convenient to store after being disassembled, and the structural strength and portability are both achieved.

The invention relates to a remote assistance method and system based on AI visual identification and interactive annotation. The method comprises the following steps: a target expert terminal establishes a remote assistance session with a target client; the target client side captures a screen image frame of a local screen and sends the screen image frame to the target expert side and the AI visual recognition module in a screen image flow mode; the AI visual identification module receives and processes the screen image flow to obtain an AI visual identification result; the target expert end generates a background layer according to the screen image stream and the AI visual recognition result, and constructs an interactive whiteboard superposition layer on the background layer; when labeling is carried out, the target expert end converts a labeling action into labeling instruction data and sends the labeling instruction data to the target client; and rendering the corresponding annotation content on the whiteboard superposition layer above the local screen of the target client.
