Abstract

The invention relates to a three dimensional (3D) radio frequency mouse which comprises a hand type emitter. The hand type emitter is provided with a transmission controller (1) and a radio frequency emitter (2), wherein the transmission controller (1) is used for controlling the transmission of an operation instruction code, the radio frequency emitter (2) is used for sending the operation instruction code and is provided with an antenna. The 3D radio frequency mouse is characterized by further comprising an MEMS triaxial accelerometer (4) and an idler wheel button (3), wherein the MEMS triaxial accelerometer (4) is used for detecting a displacement signal, and the idler wheel button is used for generating control instructions. The output end of the idler wheel button (3) is connected with the input end of the transmission controller (1), the transmission controller (1) is connected with the radio frequency emitter (2) provided with the antenna through a data port and a control port, and the MEMS triaxial accelerometer (4) is connected with the transmission controller (1) through an operational amplifier. The 3D radio frequency mouse has the advantages of being good in static measurement effect and small in size.

Description

technical field [0001] The invention relates to an input device of a data processing device, in particular to a 3D wireless radio frequency mouse. Background technique [0002] The mouse used as computer input has been very common parts, but the mouse under the use environment away from the desktop is also uncommon. This type of mouse that leaves the desktop to realize aerial positioning is called an air mouse. Chinese patent document CN201075204Y disclosed "a wireless air mouse" on June 18, 2008, which includes a hand-held transmitter and a receiving device. The hand-held transmitter has a sending control unit, an RF sending module with a sending antenna, and a gyro An operational amplifier is connected between the output of the gyroscope and the sending control unit. This structure uses a gyroscope to detect the position of the handheld transmitter, but the static measurement effect of the gyroscope is poor, and the gyroscope is large in size and heavy in weight, which is...
