[0117] In some other embodiments, the first digital human does not jump to the second display screen, and accordingly, the control device controls the first digital human to display on the third display screen to interact with the second digital human. After the handover between the two digital humans is realized, the second digital human directly introduces the product. This embodiment improves the conciseness of product introduction based on digital humans.

[0118] In the embodiments of the present application, the steps 304-305 realize the process that the control device controls the digital human to jump and display between the at least one display screen based on the target product data and the at least one display screen where the target product data is located, and controls the digital human to issue the guide information and introduce the product based on the target product data. In this embodiment, when introducing the product based on the product data of the next display screen, the guide information of guiding to watch the next display screen is issued, which can improve the interactive experience and watching experience of the visiting object. It should be noted that the steps 304-305 are only one optional implementation manner to realize the process that the control device controls the digital human to jump and display between the at least one display screen based on the target product data and the at least one display screen where the target product data is located, and controls the digital human to issue the guide information and introduce the product based on the target product data. The process can also be realized by other optional implementation manners, which are not limited here. For example, the guide information is issued before the introduction, and the guide information directly indicates the introduction order of the product data respectively displayed on the at least one display screen, so as to realize the function of guiding to watch the at least one display screen through the guide information.

[0119] 306、The control device responds to receiving the service demand information issued by the visiting object, and issues an instruction based on the service demand information to the mobile robot in the exhibition hall. The instruction is used to instruct the mobile robot to provide services for the visiting object based on the service demand information.

[0120] In the embodiments of the present application, the service demand information can be voice information or text information. The service demand information can be issued by the visiting object based on the interactive invitation, or can be actively issued.

[0121] In the embodiments of the present application, the service demand information can be used to indicate obtaining an article, or can be used to indicate reaching a preset position in the exhibition hall. If the service demand information is used to indicate obtaining an article, the instruction is used to instruct the mobile robot to deliver the article to the visitor, so that the article demand of the visitor in the exhibition hall can be effectively met, and the service experience of the visitor can be improved. For example, the service demand information indicates obtaining coffee, and the mobile robot is instructed to deliver coffee to the visitor to meet the demand of the visitor to drink coffee.

[0122] If the service demand information is used to indicate reaching a preset position in the exhibition hall, the instruction is used to instruct the mobile robot to guide the visitor, so that the guide demand of the visitor in the exhibition hall can be effectively met, and the service experience of the visitor can be improved.

[0123] In some embodiments, if the service demand information is used to indicate obtaining an article, the control device displays the positions of the visitor and the mobile robot in the exhibition hall on the first display screen during the service of the mobile robot to the visitor. In this embodiment, the position of the mobile robot and the distance from the visitor can be obtained by the visitor in real time by displaying the positions of the two on the first display screen, so that the waiting anxiety of the visitor is reduced.

[0124] Optionally, the instruction also carries the position of the visitor, so that the mobile robot can deliver the article to the position of the visitor, and the article is delivered to the visitor and the mobile robot reaches the position of the visitor to guide the visitor. In some embodiments, the control device can perform three-dimensional modeling on the exhibition hall to obtain a plurality of positions in the exhibition hall, so as to facilitate identification of the position of the visitor and leading the visitor to the preset position.

[0125] In some embodiments, the mobile robot can directly interact with the visitor. For example, the mobile robot can talk to the visitor based on the voice instruction issued by the visitor, and then directly meet the service demand of the visitor by the mobile robot.

[0126] It should be noted that the serial numbers of steps 303-305 and step 306 are only for the convenience of description, and do not limit the execution order of the two steps. Steps 303-305 can be executed before step 306, or can be executed after step 306. Steps 303-305 and step 306 can also be executed simultaneously, which is not limited here.

[0127] In some embodiments, the control device further acquires the action and expression of the visitor object through the motion capture camera. During the explanation, the control device controls the digital person to interact with the visitor object in the action and expression of the visitor object. Alternatively, the control device can control the digital person to always interact with the visitor object in the action and expression of the visitor object during the explanation. Or, during the explanation, multiple interaction links can be interspersed, and the control device controls the digital person to interact with the visitor object in the action and expression of the visitor object in the interaction link. Alternatively, the acquired expression is the micro-expression of the visitor object. In this embodiment, interacting with the visitor object in the action and expression of the visitor object can improve the intimacy between the visitor object and the digital person, and thus improve the visit experience.

[0128] In some embodiments, if the interaction information is used to request to acquire the statistical data of the preset product in the preset dimension, the control device acquires the statistical data of the preset product in the preset dimension based on the interaction information, controls the digital person displayed on the at least one display screen to perform product explanation based on the statistical data, and displays the statistical data on the at least one display screen. In this embodiment, the acquisition demand of the visitor object for the statistical data is met.

[0129] Among them, the control device controls the digital person displayed on the at least one display screen to perform product explanation based on the statistical data, and displays the statistical data on the at least one display screen includes the following several cases. If the statistical data is only distributed on one display screen, the digital person displayed on the display screen is controlled to perform product explanation, and the statistical data is displayed on the display screen. For example, the interaction information is "how many chip companies are there in the park", the statistical data involves a number, then control the digital person on the display screen where the number is distributed to broadcast the number in the form of voice, and display on the display screen. For another example, the interaction information is "which chip company in the park has the strongest scientific research strength", the statistical data involves a name, then control the digital person on the display screen where the name is distributed to broadcast the number in the form of voice, and display on the display screen.

[0130] If the statistical data is distributed on multiple display screens, the digital person is controlled to jump and display on the multiple display screens to perform product explanation based on the product data on the multiple display screens, and the statistical data is displayed on the multiple display screens. For example, the interaction information is "please analyze the scientific research strength of company A from multiple dimensions", if the data of its scientific research strength involves product data such as papers, awards and products, and these product data are distributed on different display screens, accordingly, the control device controls the digital person to jump and display on multiple display screens to perform explanation based on the product data on the multiple display screens. The process is the same as step 305, and will not be repeated here.

[0131] In the embodiments of the present application, the statistical data can be generated in advance or currently. Optionally, the control device generates the statistical data based on the interaction information through generative AI. For example, the control device can analyze data such as papers and awards according to the generative AI, and then obtain the statistical result of the scientific research strength.

[0132] In some embodiments, for the products displayed in the exhibition hall, the visiting object can instruct the digital person to demonstrate the use process of the product or show the principle or internal structure of the product. The digital person can simulate a real person as a user to demonstrate, or can simulate a real person to disassemble the product to show the internal structure of the product.

[0133] Correspondingly, the control device demonstrates the product based on the target product data, including the following steps: if the interaction information is first type information, the control device displays the digital person using the first product on the at least one display screen based on the first product indicated by the interaction information and the target product data, and controls the digital person to demonstrate the use process. The first type information is information indicating to demonstrate the use process of the product. If the interaction information is second type information, the control device displays the digital person disassembling the second product and showing the internal structure of the disassembled second product on the at least one display screen based on the second product indicated by the interaction information and the target product data, and controls the digital person to demonstrate the disassembly process and the internal structure. The second type information is information indicating to show the internal structure of the product. In this embodiment, the digital person simulates a real person to meet the needs of the visiting object to fully understand the use process and the internal structure of the product, meet the service needs, and improve the service effect.

[0134] In some embodiments, if the first product is one and the target product data is distributed on one display screen, the digital person using the first product is displayed on the at least one display screen, and the control of the digital person demonstrating the use process means that the digital person using the first product is displayed on the display screen, and the digital person displayed on the display screen is controlled to demonstrate. If the first product is multiple and the target product data is distributed on multiple display screens, the digital person using the first product is displayed on the at least one display screen, and the control of the digital person demonstrating the use process means that the digital person is controlled to display and jump on multiple display screens, respectively demonstrate the use process of multiple products and demonstrate.

[0135] In some embodiments, the use process and the disassembly process demonstrated by the digital person can be generated in advance, thereby facilitating to improve the demonstration efficiency. In other embodiments, the use process and the disassembly process demonstrated by the digital person are currently generated through generative AI, thereby facilitating to utilize the powerful generation function of the generative AI and reduce the waste of storage resources.

[0136] In the embodiments of the present application, the generative AI is combined with the digital exhibition hall to add a high-intelligent, high-efficient and high-experience digital human intelligent exhibition hall service to the traditional digital exhibition hall.
