Great! LED walls can interact with people to display their surroundings.

CnBeta website news, recently, the WZ Jardins hotel in St Paul, Brazil, has installed an interactive LED wall, which can respond to the ambient noise, air quality and the interaction behavior of people in corresponding software. It is reported that this is part of the "Hacked City" project, which is used to show how technology can bring positive changes to the city. Like the exterior wall of Ontario University of art and design in Toronto, the wall of WZ Jardins is based on local data. The metal material used can be displayed in the form of audio waveform according to the surrounding environment in one day.

That is to say, people can see the environmental changes of urban life very intuitively.

In addition, people can use mobile phone software to interact with the LED wall. There are two ways of manipulating voice and gesture.

In addition, the team also installed special microphone for collecting noise and sensors for detecting air quality on this interactive external wall. LED lights can display the surrounding environment in different forms. Among them, warm colors such as red and orange are air pollution, while blue, green and other cold tones indicate that air quality is improved.
