Method and system for remote control based on electromagnetic induction

Abstract

The invention discloses a method for remote control based on electromagnetic induction, which comprises the steps that a remote controller forms induction capacitance with a human body when the human body approaches, and oscillation signals are generated when a capacitance value of the induction capacitance reaches a preset value; a remote control code value is generated according to the oscillation signals and sent to a terminal device; the terminal device receives the remote control code value sent by the remote controller, and a frequency value in the remote control code value is decoded, wherein the frequency value is oscillation frequency of the oscillation signals; the frequency value is compared with preset frequency intervals, wherein each preset frequency interval corresponds to an action of the terminal device; and when the frequency value is located at a certain preset frequency interval in a preset length of time, an action corresponding to the preset frequency interval is executed. The invention further discloses a system for remote control based on electromagnetic induction, which is used for executing the method for remote control based on electromagnetic induction. The method and the system disclosed by the invention can realize that key functions of the remote controller can be completed without contacting the remote controller, thereby improving the reliability of the remote controller and the terminal device, and improving intelligentization of the terminal device.

Description

technical field [0001] The invention relates to the technical field of remote control, in particular to a remote control method and system based on electromagnetic induction. Background technique [0002] The remote control is the most basic standard accessory of a TV, and it is also the most commonly used accessory by users. Nowadays, there are more and more TV functions, and there are more and more buttons on the remote control. In fact, the buttons commonly used by most users are the channel switch button and the switch button. However, for some users, especially the elderly and children, they are often confused when using the remote control, and do not know the corresponding functions of each button. In addition, when the user is in an environment with insufficient light, it is not easy to identify the specific position of each button. Of course, some TVs add a gesture recognition function, and the basic functions of the remote control can be replaced by gestures, but ...

However, for some users, especially the elderly and children, they are often confused when using the remote control, and do not know the corresponding functions of each button.

In addition, when the user is in a low-light environment, it is not easy to identify the specific position of each button

Of course, some TVs add a gesture recognition function, and the basic functions of the remote control can be replaced by gestures, but this function needs to add a camera to the TV to collect human gestures, and this method is also affected by the external ambient light. , it is difficult for the TV to recognize human gestures
