Embodiment Construction

[0026] exist figure 1 In the interactive electronic whiteboard system shown, the display device 13 generally has two ways of projecting pictures, front projection and rear projection. Plasma TVs, LCD TVs, and rear projection TVs belong to the rear projection method, while ordinary projectors are front projection, but they can also project images from the rear, depending on the production materials of the interactive area.

[0027] In addition to being the "curtain" of the display device 13, the interactive area 11 can also be clicked and written with an electronic pen. In order to present the content on the computer monitor in front of everyone, the screen size of the interactive area is generally 40 inches to 120 inches, or even larger; in order to operate the computer and write on the interactive area, the interactive area is required to be hard, smooth and flat surface. Typical interactive areas include glass screens of plasma TVs, LCD TVs and rear-projection TVs, whitebo...

Abstract

An electronic pen used for an electronic interactive whiteboard and a corresponding interaction control method lead a user to adopt the electronic pen as a mouse for operation or press a toolbar appearing-key so as to choose a switching tool/key for the switching between the mouse and the pen in a strip-shaped toolbar or a disk-shaped toolbar. The electronic pen can send out a code signal corresponding to the tool/key, the signal is received and identified by a signal carrier by an interactive device in an interactive zone to generate corresponding information or event which is reported to a computer, and then the computer sends out response and starts corresponding application programs to perform relevant function processing which is projected by a display device onto a whiteboard/screen. After movement is made by an operation at the front of the electronic whiteboard/screen, the operator can press the appearing-key on the electronic pen on the new position and then a floating toolbar appears on a nib position, namely, the 'toolbar follows the pen to move'.

Description

technical field [0001] The present invention relates to the technical field of interactive control of interactive electronic whiteboards, in particular to the electronic pen of the interactive electronic whiteboard, the buttons on the electronic pen, the tool bar of "follow the pen" on the interactive electronic whiteboard, and the large-screen interactive electronic whiteboard. The interactive control method of the whiteboard. Background technique [0002] In recent years, the application of multimedia projection systems and rear projection, plasma, and LCD TVs in teaching, lectures, product demonstrations, and reports has rapidly become popular. These large-screen display devices can well present digitized multimedia material on a computer. However, people have found in practice that the operator is limited to operate the mouse and keyboard in front of the computer monitor, which limits the interaction and communication between the operator and the audience. In view of t...
