Problems solved by technology
[0002] The remote control is a device used to remotely control machinery. The traditional infrared remote control is mainly composed of integrated circuit boards and buttons used to generate different messages. It has the advantage of being simple and easy to use. However, with the development of technology, Some control devices require more and more complex functions to be controlled. For example, the current TV has the functions of web browsing and playing dynamic games, and there are more and more interface elements. Therefore, the traditional remote control can no longer meet the new operation requirements. The infrared remote control itself does not provide positioning capability. Its positioning capability is actually converted into moving information by the operation of the buttons on it, and then changes the position positioning. Its relative position to the screen cannot be displayed. When the user operates Not convenient enough and will degrade user experience

The embodiment of the invention discloses a method, a device and a system for light remote control positioning. The method comprises the following steps: a light sensing film covered on a display screen of a receiving terminal device senses a light beam spot formed on the light sensing film by a light beam that is emitted by a transmitting terminal device; the device extracts position parameters of the light beam spot on the light sensing film, which are sensed by the light sensing film, and calculates out the position coordinates of the light beam spot based on the position parameters. By virtue of the method, the device and the system for light remote control positioning, the position coordinates of the light beam spot can be obtained by the light sensing film, so that remote control of interface elements can be realized.
