Interactive projection display system
The ground interactive projection system uses advanced computer vision technology and projection display technology to create a magical and interactive experience. The system can produce various special effects images under your feet. When you step into the image projected directly on the ground, you can use your feet or hands to interact with the virtual scene on the ordinary projection screen. The various interaction effects will change with your footsteps. Let you enter a wonderful world of fusion of reality and reality.
The ground interactive projection system is the real interaction between the participants and the images projected on the ground. The system consists of three parts: sensor, application server and ground display. Combine the audience of the advertisement with the content of the advertisement, so that multiple viewers can be integrated into the advertising scene. Just as everyone participates in the game at the same time, the physical movements of multiple viewers are controlled by a non-contact sensing device, like a computer mouse. The advertising content of the ground projection or wall projection creates interaction. The content of the advertisement changes differently as the participant passes or moves. For example, the projector sprinkles a wave of water on the ground, and visitors can see the “water surface†at the foot of the starting point, as if walking the lake; the fish rises along the virtual water surface with the footsteps of the activists. Ripple or wander around or gather together; the flowers bloom on the virtual grass with the footsteps of the activists; the turtles are kicked around by the footsteps of the activists, and the same kind of simulated football.
The interactive technology used in this system has a leading position in the world. It has a high degree of novelty and appreciation, and can well play an active atmosphere in the exhibition hall, increase the scientific and technological content of the exhibition, and improve the popularity of the exhibition site.
