A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.

A wireless input system includes a first computer, a second computer, a first-mode wireless connection device, a first input device and a second input device. When the first-mode wireless connection between the first input device and the first-mode wireless connection device is established and the first-mode wireless connection between the second input device and the first-mode wireless connection device is established, the first input device and the second input device can be operated to control the first computer. When the second-mode wireless connection between the first input device and the second computer is established, the second input device can follow the first input device to perform a connection switching operation. Consequently, the second-mode wireless connection between the second input device and the second computer is established.

A wireless mouse includes a mouse body and a wireless receiver. The wireless receiver is connected with a computer host. When the mouse body is operated by a user, an original information is generated. The original information is encrypted and converted into an encryption information by the mouse body. The wireless receiver receives the encryption information from the mouse body. After the encryption information is received by the wireless receiver, the encryption information is decrypted by the wireless receiver. Consequently, the encryption information is restored into the original information. After the computer host receives the original information through the wireless receiver, the computer host performs a corresponding operation.
