Description

TECHNICAL FIELD

The present invention relates to the technical field of electronic whiteboard, and in particular to a touch operation method based on an interactive electronic whiteboard and a system thereof.

BACKGROUND

An interactive whiteboard can communicate with a computer. The electronic whiteboard is connected to the computer, and the content of the computer is projected onto an electronic whiteboard screen using a projector.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a schematic flow diagram of a touch operation method based on an interactive whiteboard according to an embodiment includes steps S101 to S103:

S101, receiving, through an interactive electronic whiteboard, touch operation data, where the touch operation data includes pressure sensitive data, touch width data and touch coordinate data.

The pressure sensitive data is a pressure when a touch pressure reaches a preset pressure value; the touch width data is a maximum distance between any two points among point coordinates on the touch screen touched at the same time; and the touch coordinate data is a coordinate value when the touched point coordinates are within a preset range value.

Further, the interactive electronic whiteboard includes a touch frame; the pressure sensitive data is detected through a pressure sensor and transmitted to the interactive electronic whiteboard, and the touch width data and touch coordinate data are detected through the touch frame. The pressure sensor may be a sensor capable of detecting pressure data, such as a pressure sensitive pen or a pressure sensitive screen. The pressure sensor senses the pressure and wirelessly transmits the pressure data to the interactive electronic whiteboard.

For example, the pressure sensitive data can be detected through the pressure sensor at the tip of the pressure sensitive pen, and the touch width data and the touch coordinate data can be detected through the touch frame in the electronic whiteboard. These three kinds of data respectively correspond to information such as touch pressure, touch area and touch point movement of the touch behavior.

S102, identifying a corresponding control instruction based on the touch operation data according to a preset algorithm.

The corresponding control instruction is identified based on the pressure sensitive data, the touch width data and the touch coordinate data detected in step S101 through the preset algorithm, which enables the electronic whiteboard to generate the corresponding control instruction according to different touch operation data without clicking on the respective function button, thereby reducing the operation steps.

Further, the step S102 can be implemented by: determining whether the touch coordinate data is detected, if the touch coordinate data is detected, determining whether the pressure sensitive data is detected; if the pressure sensitive data is detected, outputting a writing control instruction, if the pressure sensitive data is not detected, determining whether the touch width data is detected; if the touch width data is detected and the touch width data is greater than a preset threshold, outputting an erasing control instruction, if the touch width data is not detected or the touch width data is less than or equal to the preset threshold, determining whether the touch coordinate data is within a preset range; if the touch coordinate data is within the preset range, outputting a page element moving control instruction; if the touch coordinate data is not within the preset range, outputting a page moving control instruction.

S103, sending the control instruction to the interactive electronic whiteboard.

This step realizes the corresponding operation on the interactive electronic whiteboard by sending the respective control instruction to the interactive electronic whiteboard, so that the user can enter the corresponding operation mode to complete the corresponding operation without clicking on the respective function button, thereby improving the operation convenience and enhancing the user experience.

Further, after step S103, the method further includes a step of controlling the interactive electronic whiteboard to respond to the control instruction: controlling the interactive electronic whiteboard to perform a response to a writing operation according to the writing control instruction, controlling the interactive electronic whiteboard to perform a response to a erasing operation according to the erasing control instruction, controlling the interactive electronic whiteboard to perform a response to a page element moving operation according to the page element moving control instruction, and controlling the interactive electronic whiteboard to perform a response to a page moving operation according to the page moving control instruction.

The page element moving operation includes movement, scaling and rotation of the page element; the page moving operation includes movement, scaling and rotation of the page. The response to the writing operation causes the interactive electronic whiteboard to enter a writing mode, the response to the erasing operation causes the interactive electronic whiteboard to enter a erasing mode, the response to the page moving operation causes the interactive electronic whiteboard to enter a page mode, and the response to the page element moving operation causes the interactive electronic whiteboard to enter a page element mode. This step, by responding to the respective control instruction, enables the touch operation of the user to directly enter the corresponding operation mode, thereby further improving the operation convenience.

Further, after step S103, the method further includes storing the control instruction, and responsive to detecting the touch operation data, storing response to the control instruction corresponding to the touch operation data. By storing the control instruction, the detection of the touch operation data directly causes the response to the control instruction corresponding to the touch operation data, thereby shortening the response time of the operation and improving the fluency of the operation.

In this embodiment, by detecting touch operation data such as pressure sensitive data, the touch width data and the touch coordinate data, and then identifying the corresponding control instruction based on the touch operation data according to the preset algorithm, and sending the control instruction to the interactive electronic whiteboard, the user can realize the corresponding operation by directly touching the interactive electronic whiteboard without clicking on the respective function button, thereby improving the operation convenience and enhancing the user experience.

The following is a preferred implementation of a touch operation method based on an interactive whiteboard of the present invention, including steps 1 to 4:

Step 1: writing on an electronic whiteboard through a tip of a pressure sensitive pen.

Step 2: detecting a pressure sensitive data using a pressure sensor at the pen tip, and detecting a touch width data and a touch coordinate data using a touch frame of the electronic whiteboard. These three kinds of data respectively reflect information such as touch pressure, touch area, and touch point movement of the user's touch behavior.

Step 3: according to the detected pressure sensitive data, the touch width data and the touch coordinate data, determining an actual operation (writing, erasing, page element movement, page movement, etc.) of the user through a preset algorithm. Then passing a calculation result to a software UI (User Interface) interaction layer.

Specifically, according to the following algorithm, the pressure sensitive data, the touch width data and the touch coordinate data are integrated and identified as an operation instruction desired by a user. FIG. 2 shows a schematic flowchart of an algorithm of a touch operation method based on an interactive electronic whiteboard according to a preferred embodiment of the present invention: determining whether a touch coordinate data is detected, and if the touch coordinate data is detected, determining whether a pressure sensitive data is detected; if the pressure sensitive data is detected, outputting a writing control instruction, if the pressure sensitive data is not detected, determining whether a touch width data is detected; if the touch width data is detected and the touch width data is greater than a preset threshold, outputting an erasing control instruction, if the touch width data is not detected or the touch width data is less than or equal to the preset threshold, determining whether the touch coordinate data is within a preset range; if the touch coordinate data is within the preset range, outputting a page element moving control instruction; if the touch coordinate data is not within the preset range, outputting a page moving control instruction. Through this algorithm, an output operation instruction (one of writing, erasing, page element movement, page movement) can be outputted. It should be noted that, in the algorithm, the determination of whether the pressure sensitive data is detected, whether the touch width data is detected and whether the touch coordinate data is within the preset range may be performed concurrently after determining whether the touch coordinate data is detected, thereby improving determination efficiency.

Step 4: the software UI interaction layer receives the output control instruction and responds to the user's operation. Specifically, the software UI interaction layer controls the interactive electronic whiteboard to perform a response to a writing operation according to the writing control instruction, controls the interactive electronic whiteboard to perform a response to an erasing operation according to the erasing control instruction, controls the interactive electronic whiteboard to perform a response to a page element moving operation according to the page element moving control instruction, and controls the interactive electronic whiteboard to perform a response to a page moving operation according to the page moving control instruction. For example, when writing on the screen with an electronic pen, the electronic whiteboard enters an writing mode, and the user can directly write on the screen; when the user touches the screen with a finger, the electronic whiteboard enters a page or page element mode, and the user can move, scale, rotate a page or a single page element therein; when the user touches the screen with the palm of the hand, the electronic whiteboard enters a erasing mode, and the user can erase a handwriting directly on the screen.

It can be seen that the method, by detecting the touch operation data such as the pressure sensitive data, the touch width data and the touch coordinate data, and then identifying the corresponding control instruction based on the touch operation data according to the preset algorithm, and sending the control instruction to the interactive electronic whiteboard, allows the user to realize the corresponding operation by directly touching the interactive electronic whiteboard without clicking on the respective function button, thereby improving the operation convenience and enhancing the user experience.
