Remote control method and system based on electromagnetic induction

Abstract

The present invention discloses a remote control method based on electromagnetic induction. The method comprises: forming an induced capacitor between a remote controller and a human body upon approaching of the human body, and generating an oscillation signal if a capacitance value of the induced capacitor reaches a predetermined value; generating, according to the oscillation signal, a remote control code value, and sending the same to a terminal device; receiving, by the terminal device, the remote control code value sent by the remote controller, and decoding the remote control code value to obtain a frequency value, wherein the frequency value is a oscillation frequency of the oscillation signal; comparing the frequency value to predetermined frequency intervals, wherein the predetermined frequency intervals respectively correspond to an action of the terminal device; and if the frequency value is within one of the predetermined frequency intervals for a predetermined duration, executing an action corresponding to said predetermined frequency interval. The present invention further discloses a remote control system based on electromagnetic induction, and the system is configured to execute the remote control method based on electromagnetic induction. The present invention achieves the function of a remote controller button without a contact with a remote controller, thus improving the reliability of a remote controller and terminal device, and making the terminal device more intelligent.

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
