Embodiment Construction

[0022] A method for realizing double-board interaction based on an electronic whiteboard, the method for realizing double-board interaction is applicable to two electronic whiteboards, a computer and two projectors, the two projectors and the two electronic whiteboards are connected to the computer, defined by the computer Projected main screen and sub-screen, the main screen is operated by the main screen driver, the sub-screen is operated by the sub-screen driver, the electronic whiteboard connected with the main screen driver is the main electronic whiteboard, and the electronic whiteboard connected with the sub-screen driver The whiteboard is an auxiliary electronic whiteboard, and the electronic whiteboard driver distinguishes the main screen driver and the auxiliary screen driver through PID and VID. The main screen driver only receives the data of the main electronic whiteboard, and the auxiliary screen driver only receives the data of the auxiliary electronic board.

Abstract

The invention provides a double-board interaction implementation method on the basis of electronic white boards. The double-board interaction implementation method includes that an electronic white board driving unit acquires the resolution and start coordinates of a main screen and the resolution and start coordinates of an auxiliary screen, the main screen and the auxiliary screen are respectively corrected by a positioning algorithm, and then an electronic white board software unit informs the electronic white board driving unit that a current service mode is a double-board interaction mode; and the electronic white board driving unit establishes a global coordinate system, when a mouse is operated on a main window of the electronic white board software unit, an analog function MOUSEEVENT of the mouse utilizes the global coordinate system for computation via an analog formula of the mouse, so that coordinates of the mouse are obtained, and mouse operation is executed. The other screen can be used for freely displaying contents for a user, double-board interaction is implemented, the user can simultaneously operate differently on the main electronic white board and the auxiliary electronic white board, the main electronic white board and the auxiliary electronic white board cannot affect each other, double-pen writing can be implemented on the main window of electronic white board software, and window dragging between the main screen and the auxiliary screen is supported.

Description

【Technical field】 [0001] The invention relates to the field of electronic whiteboards, in particular to a method for realizing interaction between two boards based on the electronic whiteboard. 【Background technique】 [0002] With the rapid development of computer technology, various multimedia courseware integrating sound, image, text and video have entered the classroom. Electronic whiteboards, which integrate computer technology, display technology, network technology, photography and camera technology, etc., have emerged in this digital age. The electronic whiteboard consists of a hardware electronic whiteboard, an electronic whiteboard drive unit for connecting and positioning with the hardware electronic whiteboard, an electronic whiteboard software unit that presents to the user and provides an editing window for the user, and recognition software that composes handwriting input. However, the application of the existing electronic whiteboard technology in teaching is...
