What is the difference between dual screen interaction and dual screen interaction in the exhibition hall?

In today's digital display era, dual screen linkage and dual screen interaction have become an indispensable element in the design of exhibition halls. Although they are similar in some aspects, they are significantly different in functions and implementation methods.

Dual screen linkage, as the name implies, means that two screens are connected together in some way to realize the synchronous display of information. Usually, this design is to present the content in a broader perspective, or to enhance the expression of information by comparing the content on two screens. For example, in the exhibition hall displaying geographical information, dual screen linkage can be used to display the weather conditions at different places at the same time, or display the weather changes at different times at the same place. This design pays more attention to the synchronization and contrast of information.

In contrast, the dual screen interaction emphasizes the participation of the audience. Through touch, gesture recognition and other technologies, the audience can directly interact with the screen and operate the content on the two screens. This design method not only allows the audience to participate in the exhibition more deeply, but also can provide a richer and personalized interactive experience. For example, in the science and technology exhibition hall, the audience can control the 3D models on the two screens through gestures to rotate, zoom in and other operations, so as to more intuitively understand the details and characteristics of the products.

In general, dual screen linkage and dual screen interaction are both important display means in the exhibition hall design, and they have their own unique functions and advantages. Dual screen interaction pays more attention to the synchronization and contrast of information, while dual screen interaction emphasizes audience participation and interactive experience. When designing the exhibition hall, appropriate technical means should be selected according to the display content and the characteristics of the target audience to achieve the best display effect.
