Remote controller

Abstract

The invention discloses a remote controller, which comprises a three-axis acceleration sensor, a micro-controller and a gyroscope, wherein the three-axis acceleration sensor is connected with the micro-controller, is used for acquiring acceleration signals of X, Y and Z axes, and transmits the acceleration signals to the micro-controller; the micro-controller is connected with the gyroscope, and analyzes an acceleration signal acquired by the acceleration sensor, and the signal is effective when a value of the acceleration signal is within the preset range; and the gyroscope converts the effective acceleration signal, converts the acceleration signal into an angle signal, and judges the movement direction of a user according to the angle signal. The invention can conveniently realize the control on menu options by waving the remote controller in the space. The remote controller has simple operation and broad applicable crowd.

Description

technical field [0001] The invention relates to a remote controller for controlling electric appliances. Background technique [0002] With the development of science and technology, many remote controls and household appliances are becoming more and more intelligent and humanized. [0003] On the existing remote controller, many keys (including number keys, direction keys and other keys) are arranged or a joystick is arranged, and menu selection is realized through the keys or rocker. [0004] The disadvantage of this control method is that it brings inconvenience to the user in some cases. For example, in the case of dark light, misoperation will occur because the keyboard cannot be seen clearly; or due to age reasons (such as children's hands are small and cannot hold the joystick firmly), the remote control with the joystick cannot be well controlled. Etc., all can bring inconvenience to the user's use. [0005] In addition, most of the existing remote controllers use...

Problems solved by technology

[0004] The disadvantage of this control method is that it will cause inconvenience to users in some cases.

For example, in the case of dark light, misoperation will occur because the keyboard cannot be seen clearly; or due to age reasons (such as children's hands are small and cannot hold the joystick firmly), the remote control with the joystick cannot be well controlled. etc. will cause inconvenience to users

[0005] In addition, most of the existing remote controls use infrared transmission. Infrared transmission requires an angle between the remote control and the remote control object, that is, the remote control must be aimed at the remote control object, and the infrared transmission is unidirectional.
