Embodiment Construction

[0037] A method for controlling an intelligent pointer in a cloud classroom based on wifi, comprising the following steps:

[0038] Step 1. Client and server connection initialization

[0039] (1) Connection initialization: The client sends a protocol data unit PDU of a connection request to the server to initialize the connection. After receiving the PDU from the client, the server returns a response packet containing the connection confirmation.

[0040] (2) Basic setting exchange: the server sends a PDU containing initialization setting information to the client, and the included data includes the resolution information of the server's desktop, etc.

[0041] (3) Identity authentication: After receiving the initialization information, the client sends a secure interaction PDU to the server, which contains a 16-byte random number sequence encrypted by a key. This random number sequence is encrypted using a pre-agreed key encryption mechanism. After the server receives the ...

Abstract

The invention discloses a method for controlling a cloud classroom intelligent pointer based on wifi (Wireless Fidelity). With the method, a user can extremely conveniently operate a virtual desktop by a smart mobile, a panel personal computer and other terminals. The method is particularly suitable for the teaching work of a multi-media classroom. The invention has the positive effects of providing a remote control method from the clients of the smart mobile and the panel personal computer to a cloud terminal, defining a remote control method combining desktop click control, gesture control and memory custom virtual keyboard control and realizing a function of applying the mobile and other intelligent terminals to control and operate a virtual machine on a background cloud server and enabling a foreground cloud server to display a background virtual desktop with a projector in real time. The operation of a PPT (Power Point Text) is also defined by the method, so that the PPT can be conveniently operated by the mobile and a pad terminal, namely the function of using the mobile, the pad and other terminals as the pointer is realized by the method.

Description

technical field [0001] The invention belongs to the technical field of computer multimedia, and in particular relates to a method for controlling an intelligent pointer of a cloud classroom based on wifi.
