The P4.81 LED display can of course be interactively operated, and it has certain advantages in interactive operation. If you want to know why P4.81 LED floor tile screen can be interactively operated, you need to explain its sensing principle and its characteristics.
The sensing principle:
The interactive floor tile screen is based on the LED floor tile screen, which adds a sensing and interactive function. The LED floor tile display is equipped with pressure sensors, capacitive sensors or infrared sensors.
When a person moves on the floor tile screen, the sensor can sense the position of the person and feedback the trigger information to the main controller, and then the main controller logic After the judgment, the corresponding display effect is output. For example, with the help of infrared sensor, it can track people’s motion trajectory, and can follow the human body’s activities to present real-time picture effects, so as to achieve effects such as actors and audience walking by, water ripples under their feet, and flowers blooming.
The technical principle :
The multimedia interactive system is composed of an image motion capture device, a data transceiver, a data processor and an LED floor tile screen;
The image motion capture device realizes the capture and collection of participant images and motion data;
The function of the data transceiver is to realize the express transmission of data back and forth between motion captures;
The data processor is the core part that realizes the real-time interaction between participants and various effects. It analyzes and processes the collected images and motion data, and realizes the combined processing with the inherent data in the processor.
Fast and flexible installation: direct installation without tools or rail installation can be used;
High load-bearing performance: Aluminum alloy material structure, the high load-bearing capacity can reach 1.5 tons per square meter;
Excellent maintenance performance: can be directly exchanged without removing the adjacent cabinet;
High-contrast design: technically designed mask, clear playback effect;
Outstanding low-brightness and high-gray effect: the display gray level is uniform and the consistency is good.
In addition, let’s take a look at the difference between the P4.81 LED floor tile screen and the traditional LED floor tile screen, so as to have a clearer understanding of the reason why it can be interactively operated.
What is the difference between P4.81 LED floor tile screen and traditional LED floor tile screen:
The first is the difference in control software. The traditional LED display screen is on the playback side, and only ordinary playback software is needed to play the video source without receiving other signals. The interactive LED display screen is different. It must not only be able to play, but also be able to receive the coordinate information of the interactive point sent back from the display. After receiving the position coordinate information, the control software can call it according to the received coordinate information. Different program files and video files are played.
The second is that the direction of data transmission is different.
The traditional LED floor tile screen data is mainly transmitted from the control end to the display end, which is basically one-way, while the interactive LED floor tile screen adds data return, which is a two-way transmission.
The third is the difference in the display end of the LED screen.
The traditional floor tile screen only plays a display role, while the LED interactive floor tile screen also needs to sense, collect, and transmit the coordinate information of the interactive point of the interactive audience to locate the interactive point.
As a new type of signal input device, the interaction of P4.81 LED floor tile screen is currently the simplest, convenient and natural way of human-computer interaction. The screen of the floor tile screen creates a lively audio-visual interactive effect, which gives With a brand-new look, multimedia is a very attractive brand-new multimedia interactive device. Since the P4.81 LED floor tile screen is used in the field of short-distance display, the requirements for the display effect of the product are also relatively strict, in order to meet the needs of near-distance display.
The capture of signal action is the key to interactive operation in the use of the P4.81 LED floor tile screen. The P4.81 LED floor tile screen can be used for motion capture according to the needs of the activity. The capture device is the LED floor tile screen with a thermal sensor. The data receiving and receiving system transmits the signals taken by each LED floor tile screen module sensor to the data processor.
The data processor performs data analysis and processing on the sent signal, and the generated data scene is connected to the system. In the display part of the LED floor tile screen, the virtual data and the virtual scene data will be sent back to the P4.81 LED floor tile screen after the completion of the docking, and the P4.81 LED floor tile screen can realize the virtual scene screen.
Therefore, the interactive operation of P4.81 LED floor tile screen is feasible.
