Embodiment 1

[0034] Embodiment 1: A system for controlling a display device, refer to the attached figure 1 , including a wearable device 1, a personal computer 2 and a display device 3, the wearable device 1 can be a smart wearable device with a microphone and / or a speaker such as a smart earphone, a smart watch, a smart bracelet or smart glasses, according to the use environment According to the future development trend, more products can be expanded. The personal computer 2 can be a hand-held smart PC terminal such as a mobile phone or a tablet notebook. Here, a mobile phone that is popular per capita and has a microphone and a loudspeaker is generally used as the relay personal computer 2. The display device 3 is a monitor, a television, a projector, and the like.

[0035] Wherein, the sum of the number of microphones and speakers on the wearable device 1 and the personal computer 2 is not less than three, and the wearable device 1 and the personal computer 2 establish an ultrasonic ch...

Embodiment 2

[0036] Embodiment 2: A method of controlling a display device, refer to the attached figure 1 , including the following steps:

[0037] S1: After wearing the wearable device 1, the user makes command actions;

[0038] Here, the wearable device 1 is a smart watch, which is worn on the user's wrist;

[0039] Among them, when the command action is made, the speaker of the wearable device 1 is activated in advance, and the ultrasonic positioning signal is continuously sent out. The ultrasonic positioning signal carries device pairing information and ultrasonic positioning data (signal sending time, difference between different signals, etc.).

[0040] S2: Place the personal computer 2 directly in front of the display device 3, turn on the infrared control function, and establish a connection with the display device 3;

[0041] At the same time, the personal computer 2 turns on at least two microphone units, listens to the direct ultrasonic positioning signal, and uses the time-o...

Embodiment 3

[0047] Embodiment 3: A method for controlling a display device, based on Embodiment 2, wherein the connection mode of the personal computer 2 to the display device is a wired connection; the display device 3 is a projector.

[0048] Using the above scheme, use a personal computer with a microphone or a speaker as a relay device, use the microphone and speaker that come with the personal computer and the wearable device to establish a sound wave connection channel, and sense the position change information of the wearable device through sound wave positioning. The personal computer In this way, the user's action command information is obtained, and then the personal computer compiles the action command information into an executable command sequence for the display device, which not only realizes the convenient operation of gestures for all types of display devices, but also does not need to install any additional modules, and there is no extra cost , At the same time, it also a...

Abstract

The invention discloses a system and method for controlling display equipment. The system comprises wearable equipment which is worn on a user and is used for representing an action command of the user, a personal computer configured for acoustic connection with the wearable equipment, and the display equipment which is fixed relative to the personal computer and is used for receiving the action instruction information transmitted by the personal computer. A personal computer with a microphone or a loudspeaker is used as relay equipment, position change information of wearable equipment is sensed through sound wave positioning, the personal computer obtains action instruction information of a user, and the personal computer compiles the action instruction information into an instruction sequence which can be executed by display equipment. Gesture convenient operation of all types of display equipment is achieved, no extra module needs to be additionally installed, redundant cost is avoided, and meanwhile the problems that when a personal computer directly controls the display equipment, infrared signals are prone to being shielded, and the control range is limited are solved.

Description

technical field [0001] The invention relates to a system and method for controlling a display device, belonging to the technical field of sound waves. Background technique [0002] A display device is a display tool that can display electronic files on a screen through a specific transmission device and then reflect them to the human eye. The display receives electronic signals and forms an image. Common display devices include televisions, monitors, and projectors. [0003] With the popularization of intelligence, more and more smart devices can be operated through gesture commands. However, on the one hand, wearable devices are not equipped with infrared function modules and cannot be connected to display devices, making it difficult to remotely control display devices. Control, even if you use a mobile phone with an infrared function module to connect to the display device for control, the control method is still a rigid button operation, which is less convenient. At the ...
