What display technologies are used by the virtual host in the multimedia digital exhibition hall

Virtual host is also called virtual commentator, virtual welcome, virtual door welcome, etc. The application of virtual presenter is the combination of speech recognition technology and image production and synthesis technology. It connects users and displays content through a computer. When the user enters the guidance area, the virtual presenter's commentary will start by itself, and begin to vividly introduce the contents of the exhibits, which will amaze the visitors and bring a good technology experience. In the multimedia digital exhibition hall, what technologies are used by the virtual host for intelligent interactive explanation and display? Now let's take you to understand.

The forms of expression of virtual presenters can be roughly divided into live interpretation and shooting and 3D production:

　　 1、 The technology used in the production of virtual presenters' live commentary:

1. Shooting: The production of the virtual host needs to shoot first to record a complete video of the host introducing various products.

2. Image matting: then we need to conduct post processing production in the later stage, and use AE post software or other software to extract the virtual host on the green cloth.

3. Synthesis: finally, synthesize the host to the specified picture, which can be 3D technology synthesis or live shooting.

　　 2、 Explanation of 3D modeling characters of virtual host:

1. Modeling and design: use 3D modeling software and graphic design tools to produce the appearance, clothing and other features of the host image.

2. Motion capture: through motion capture technology, the actions and expressions of real hosts or actors are recorded and converted into digital motion data.

3. Animation production: use animation production software to apply action data to the virtual host to create smooth actions and expressions.

4. Speech synthesis: use speech synthesis technology to convert text into speech, and let the virtual host conduct voice interaction.

5. Programming and intelligence: use computer programming and artificial intelligence technology to enable the virtual host to respond and respond accordingly according to user input, changes in the environment, etc.

From this, we can learn that the application of virtual presenters in the exhibition hall will adopt the technology of live virtual imaging or 3D animation modeling. In the exhibition hall, the virtual presenter usually uses projection, and the projection technology used by the virtual presenter is mostly rear projection, so this also reflects the rear projection technology.

In the exhibition hall of the exhibition hall, as an exhibition item that can interact with users, the virtual host system needs infrared induction processing, large screen display technology and other assistance for its operation. The cooperation between such interaction systems enables users to achieve the effect of interaction with exhibition items by approaching them.

In order to meet the needs of multiple users, we have added a voice recognition system to the virtual host system. At the same time, we have also added a variety of language systems when making voice dubbing of virtual image effects to meet the needs of users. Meet the needs of all kinds of people and realize real intelligence.
