Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a multi-terminal courseware real-time interaction method, including a teacher terminal and a student terminal, and the teacher terminal and the student terminal are computers or controllers that can be connected to the network. The method includes the following steps:

[0033] S110 teacher end and student end load controller controller.html and h5 interactive courseware of html format respectively; Described controller controller.html comprises toolkit module sdk.js, property module status.js, queue module queue.js, described h5 interactive courseware refers to the html pages written by html5, css3 and js;

[0034] S120 The controller controller.html uses the attribute module status.js to initialize information, and uses the queue module queue.js to serialize the information queue after completing the information initialization. After serializing the queue, request to load the h5 interactive courseware;

[0035]...

Embodiment 2

[0043] The present invention provides a real-time interactive method for multi-terminal courseware. The basic idea is to complete the communication with the client through the controller.html, perform queue control, and execute the queue circularly. Extract the unique sdk file and bind each event function. Load the courseware, perform various actions in the courseware, and display animation effects; for example figure 2 As shown, the specific process method steps include,

[0044] S210 loads controller.html; both the student end and the teacher end load.

[0045] S220 requests information initialization and serialization queue; the student side and the teacher side are synchronized.

[0046] S230 function binding, corresponding action information with functions in SDK;

[0047] S240 performs SDK analysis after receiving the action information;

[0048] After the S250 parses, it will be displayed locally;

[0049] After S260 is displayed, the action information received b...

Embodiment 4

[0061] On the other hand, the present invention also provides a system for running the above embodiments, such as Figure 4 As shown, a multi-terminal courseware real-time interactive system 100 is provided, including a teacher terminal 110 and a student terminal 120, the teacher terminal 110 and the student terminal 120 respectively include a controller 130, and the controller 130 includes a toolkit module 131 , attribute module 132 and queue module 133;

[0062] The teacher's terminal 110 and the student's terminal 110 are used to load the controller 130 and h5 interactive courseware, and the h5 interactive courseware refers to an html page written by html5, css3 and js;

[0063] Described controller 130 is used for utilizing attribute module 132 to carry out information initialization, utilizes queue module 133 to serialize information queue after completing information initialization, after serializing queue, request to load described h5 interactive courseware;

Abstract

The invention relates to a multi-terminal courseware real-time interaction method comprising a teacher terminal and student terminals. The method comprises the steps that the teacher terminal and the student terminals load a html-format controller and interaction courseware; the controller performs information initialization by using an attribute module, serializes information queues by using a queue model after information initialization, and requests loading of interaction courseware; the teacher terminal acquires operation data relating to the interaction courseware and sends the operation data to a tool kit module; an animation effect module in the tool kit module executes animation effect play and a message construction module in the tool kit module generates messages according to the operation data; the messages are sent to tool kit modules in the students terminals and an event trigger module in each student terminal triggers animation play. The method guarantees the uniformity and orderliness of execution of the multi-terminal animation effect, guarantees the interaction of a multi-terminal class process and allows audio / video files to be loaded with less occupation of CPUs.

Description

technical field [0001] The invention relates to the field of Internet teaching, in particular to a method for real-time interaction of multi-terminal courseware and a real-time interactive system for multi-terminal courseware. Background technique [0002] Start the client software on the PC side, load the interactive courseware, and use the program to realize multi-terminal interactive real-time synchronous teaching (including the display synchronization of animation effects such as clicking and dragging, and the synchronization of audio and video playback), and realize multi-terminal interactive teaching efficiently and conveniently. . The current common method is to record the screen and share the teacher's interface through media streaming, which will bring high bandwidth requirements. In addition, in some other implementations, if the page operation animation on the teacher’s end is converted into an image for display, it is easy to cause distortion, and the user canno...
