Embodiment 1
[0063] Such as figure 2 As shown, an interactive electronic demonstration system includes:
[0064] An operation terminal 1, used for storing and demonstrating display content and performing demonstration operations;
[0065] Display terminal 2, used to display the display content of the operation terminal;
[0066] An interactive controller 3 is used to obtain the display content and operation information of the operation terminal 1 and send them to the display;
[0067] The video input interface of the interactive controller 3 is connected with the video output interface of the operation terminal 1 by wire or wirelessly, and the video output interface of the interactive controller 3 is connected with the video input interfaces of the operation terminal 1 and the display terminal 2 by wire or wirelessly.
[0068] In this embodiment, the operation terminal 1 is composed of a notebook computer 11 and a tablet computer 12 , and the display terminal 2 is composed of a projecto...
Embodiment 2
[0074] The difference between this embodiment and Embodiment 1 is that the display terminal 2 is a large-screen computer, such as image 3 shown.
Embodiment 3
[0076] Such as image 3 As shown in the interactive electronic demonstration system, the interactive controller 3 is equipped with interactive control software, the display terminal 2 is also used for demonstration operations, and the interactive controller 3 is also used to identify the operation actions of the display terminal and simulate mouse or keyboard operation signals Returning to the notebook computer 11, the notebook computer 11 makes a corresponding response according to the operation signal. Demonstration steps such as Figure 5 Shown:
[0077] The computer image of step 1 notebook computer 11 is transmitted to interactive controller 3;
[0078] Step 2 The interactive controller 3 transmits the image to the large electronic screen 23 for the audience to watch the demonstration;
[0079] Step 3 Simultaneously, the interactive controller 3 transmits the image to the tablet computer 12 in a wireless manner;
[0080] Step 4 The presenter uses the tablet computer 1...
