"Magic wall" tells me, what do customers think? " The magic mirror in the fairy tale turned into a "magic wall" at the second Expo, not to tell visitors "beauty is not beautiful", but to help visitors "cross" to all parts of the world in a second and see how digital technology can serve all walks of life.

Deloitte, the exhibitor of the second fair, confirmed to reporters that as the key exhibit of its participation in the fair, "smart wall" has traveled from the United States to China, and will show the charm of digital technology for exhibitors from home and abroad in "four leaf grass".

At first glance, "magic wall" seems to be a display screen that introduces Deloitte's achievements in digital innovation with partners in different industries and fields. Can be studied carefully and found that Deloitte can be described as "a thousand people and a thousand faces" -- want to know how the hotel industry can read the minds of the guests with the help of digital technology, want to know how the pharmaceutical enterprises can accurately obtain the needs of customers, want to know how to improve the efficiency of the smart city "Magic wall" can give answers in combination with specific cases, and at the same time.

Deloitte said that "magic wall" is actually a touch data visualization intelligent product, which is mainly used in the field of smart city and enterprise analysis. From the surface, "magic wall" is a smooth screen, but there are many sensors at the back of the screen, which can be projected by perceptual touch. Once the visitors stand in front of the "magic wall" and choose the topic of interest, the sensor of the "magic wall" will start to operate. Using animation projection technology and graphics technology, it will show the innovation highlights or growth process of a city or an enterprise to the visitors in 10 minutes, and allow the visitors to try according to their own needs in the interaction process.

"Digital solutions are an important part of the exhibition for us to participate in the second China International Fair." Deloitte said that the birth of the "magic wall" provides a new way to explain digital solutions. Because in the past, whether Deloitte or many enterprises or institutions introduced specific content, they basically displayed it in the form of point-to-point, one-to-one ppt. "Magic wall" is different. It can digitize and visualize the solution according to the needs of visitors, and provide immersive and journey like experience in the form of many to many omni-directional display. Through "magic wall", the innovative services and solutions that Deloitte wants to show at the second Expo can be presented to people through multiple sensory dimensions. A "magic wall" can be divided into several areas, and different themes can be explained at the same time to meet the personalized needs of visitors and realize many to many interaction.

Deloitte said that in order to make full use of the influence of the Expo, many themes and cases have been input for "magic wall" in advance, covering digital, artificial intelligence, design thinking, Internet of things, big data analysis and other aspects. These cases come from all over the world, which means that as long as people stand in front of the "magic wall", they can "cross" all over the world to see what digital innovations are being explored by local government agencies or enterprises, and even use the interactive function of the "magic wall" to create a virtual brainstorming.

For example, in the theme of "digital + city", visitors can "cross" to Buenos Aires, Argentina, to see how local people can adopt the way of human-computer cooperation, use Internet sensors to receive complaints from citizens on social media, effectively solve urban problems, and shorten the problem-solving time by 93%. Or set the destination as Santander, Spain, where 20000 sensors installed on infrastructure such as lamp posts are used to collect data, monitor traffic, pollution and resource use, and develop a roadmap for future development

Similarly, manufacturing enterprises, medical enterprises and hotel enterprises from all over the world are welcome to experience their innovation pulse through the magic wall.

Deloitte said that the fair is not only a platform for displaying the latest products and services, but also a platform for jointly exploring the future development of the world economy. At this year's Expo, Qiao Lihe, chairman of Deloitte global strategy committee, will also participate in the sub forum of Hongqiao International Economic Forum, "digital era and e-commerce innovation and development", and discuss the innovation and development of digital era with guests from all over the world. In Deloitte's view, mobile Internet, cloud computing, big data and other new technologies have been widely used, and new formats and modes such as sharing economy emerge in endlessly. Through "magic wall", we can better display the combined results of various industries and digital technologies, and realize the visualization of the whole process solutions for multiple scenes of smart city. We also hope to introduce "magic wall" through this Expo Entering China and introducing more Chinese cases will enable Deloitte to better interact and communicate with the government, industry and enterprises.
