Abstract

The invention discloses a two-dimensional wireless mouse which comprises a far-end subsystem and a host-end subsystem. The far-end subsystem comprises an MEMS (micro-electromechanical system) gyroscope and acceleration sensor, a microcontroller and a wireless radio-frequency transmission module; the host-end subsystem comprises a wireless transceiver module, a main controller and a USB (universal serial bus) interface; turning signals and acceleration signals, collected by the far-end subsystem, of the two-dimensional wireless mouse transmitted to the host-end subsystem through the wireless radio-frequency transmission module after subjected to filtering processing by the microcontroller, the wireless transceiver module of the host-end subsystem transmits received wireless radio-frequency signals to the main controller, and the main controller performs coding processing on input signals according to the mouse communication protocol and is connected with a host through the USB interface. The two-dimensional wireless mouse can be operated optionally in the space and is high in flexibility and extension performance.

Description

technical field [0001] The invention relates to a two-dimensional wireless mouse and belongs to the technical field of computer auxiliary equipment. Background technique [0002] In the process of human-computer interaction, the understanding of the system state and operation process of the computer is realized through the human-computer interface. Whether in the notebook computer or desktop computer market, the mouse is the most popular input device with click and movement as the main input mode besides the keyboard. [0003] In short, the existing mouse controls the input and response of the device through buttons, and has defects such as slow response time, low sensitivity, and being limited to a smooth and flat operating surface. Contents of the invention [0004] In view of the above-mentioned problems in the prior art, the object of the present invention is to provide a two-dimensional wireless mouse that can be operated freely in space. [0005] For realizing abov...
