Method and device for controlling electronic device through electronic terminal

Abstract

The invention provides a method and device for controlling an electronic device through an electronic terminal. The method includes the steps of a, receiving sounds sent by at least two loudspeakers of the electronic device and radio frequency signals sent by a radio frequency module of the electronic device at various different moments; b, determining the positions of the electronic terminal at different moments according to the received sounds and the received radio frequency signals; c, determining movement information of the electronic terminal according to the positions; d, sending the determined movement information to the electronic device. By means of the method and device, according to the received sounds sent by the loudspeakers of the electronic device and the received radio signals sent by the radio frequency module, the high-precision positioning and tracing of the electronic terminal are achieved, and therefore the high-precision control over the electronic device is achieved, and operation is easy for users.

Description

technical field [0001] The present invention generally relates to the technical field of electronic equipment control, and in particular to a method and equipment for controlling electronic equipment at an electronic terminal. Background technique [0002] With the development of electronic technology, there is now a new type of input device—the air mouse, which can operate the screen cursor like a traditional mouse, but it does not need to be placed on any plane, and can be used directly by shaking it in the air. The air mouse can control various electronic devices, such as televisions, personal computers, motion-sensing game consoles, and television set-top boxes. [0003] At present, the common air mouse senses the change of direction and speed through the built-in acceleration and gyroscope sensors, and then sends the position change information to the controlled electronic device through wireless transmission, and realizes the operation control of the electronic device ...

AI Technical Summary

Problems solved by technology

[0003] At present, the common air mouse senses the change of direction and speed through the built-in acceleration and gyroscope sensors, and then sends the position change information to the controlled electronic device through wireless transmission, and realizes the operation control of the electronic device with the cursor mark, but the positioning The tracking error is large, about 30cm

[0004] The camera-based visual recognition technology can realize high-precision positioning and tracking of user operations, but the method is not only complicated to calculate and difficult to implement, but also needs to be equipped with an additional camera, which is costly

[0005] It can be seen that the existing air mouse technology has the disadvantages of large positioning error, complex calculation, and high cost.
