when the exhibition meets technology, how can you miss this interactive feast?

(I) what is a lidar interactive projection

laser radar, English name LiDAR(Light Detection and Ranging) , is an advanced sensor technology, called super accurate "distance detection master". Its working principle is based on the emission, propagation and reception of light. The laser emits high-frequency laser pulses that propagate toward the target object at the speed of light. When the laser pulse encounters the target object, part of the light is reflected back, and the receiver in the lidar device captures the reflected laser light. The timer inside the device records the time interval between the emission and reception of the laser pulse. Since the speed of light is known, the distance between the light pulse and the target object can be calculated according to the formula "distance = speed of light × time/2. By emitting and receiving laser pulses at different angles, it is possible to construct a complete three-dimensional outline of the object and draw an extremely accurate three-dimensional map of the environment.

(II) magical interactive journey

when the laser radar and interactive projection system combined, it opened a magical interactive journey. The motion sensors in the system are like clever little guards, always watching the arrival of visitors. Lidar can track the visitors' every move in real time. No matter where you are in the exhibition space, it can quickly capture your movement information and transmit this information to the projection system. The projection system adjusts the display content in real time according to the received information, and presents the picture effect that matches your action. For example, when you stretch out your hand and wave the drawing circle forward, there may be rippling waves in the projected picture. If you jump upward, brilliant fireworks may rise in the picture. What's more, it also supports multiple people interacting at the same time. At the exhibition site, different visitors can interact with the projected content at the same time, and everyone's actions can be accurately identified and responded to, as if an interesting interactive carnival.

(III) companies show new ways

in the corporate showroom, the "magic wall" created by lidar is definitely an eye-catching artifact. It seems to have life in general, according to your actions to respond. Lidar sensors hidden inside the walls keep track of your location and movement, allowing the projected content to change as you interact.

when potential customers walk into the showroom and gently touch or walk around in front of the "magic wall", wonderful things happen. With just one touch, you can trigger the wonderful part of the product demonstration and view the detailed specifications of the product. This immersive display allows customers to have a more intuitive and in-depth understanding of the product, which greatly enhances the attractiveness and persuasiveness of the product.

in the field of education, the interactive projection of lidar has set off a storm of change, so that learning is no longer boring. In the science museum or science and technology expo, it opens a new door of knowledge for students. In the past, students in the face of book knowledge, often feel abstract difficult to understand, learning has become boring. Nowadays, with the interactive projection of laser radar, the learning scene becomes lively. Students can participate in educational games or simulations, using body movements to manipulate projected elements, as if they were in a fantasy paradise of knowledge.

(V) knowledge and fun dance

interactive learning is like a magic key that makes knowledge easier to understand and remember. At the Science Museum, for example, students can control the motion of the planets in a model of the solar system like an interstellar commander. With a light wave, you can change the orbits of the planets, observe their orbits, and easily understand the mysteries of the solar system while having fun. Or in virtual games, students can easily understand complex physical concepts by interacting with projected objects. When students push the objects in the projection, they can intuitively feel the effect of physical phenomena such as friction and gravity, and the originally obscure physical knowledge becomes within reach.
