Interactive function manual (lidar navigation)
1. Core technology of interactive function of Ai digital human advertisement screen.
ASR (Automatic Speech Recognition): Ai digital people's advertising screen supports multilingual and dialect recognition, which can accurately capture users' voice instructions, maintain a high recognition rate even in noisy environments, and quickly convert voice into text information, laying the foundation for subsequent interactive response.
TTS (Speech Synthesis Technology): The advertising screen of Ai digital people can generate natural, smooth and emotional speech, and can adjust the speech speed and intonation according to the interactive scene, such as using a calm tone when explaining and a friendly tone when guiding, so that users can get a more comfortable listening experience.
Collaborative operation: The advertising screen of Ai digital people is seamlessly connected with TTS. After the user sends a voice command, ASR quickly recognizes it and transmits it to the system. After the system processes it, it instantly generates a voice response through TTS to realize real-time and natural dialogue and interaction.
2. Lidar navigation and interactive collaboration of Ai digital human advertisement screen.
Lidar performance: the detection distance is 25 meters, the wavelength is 905nm, and the working area is 260. It can accurately perceive the surrounding environment and plan a reasonable moving path for Ai digital people.
The combination of navigation and interaction of advertising screen of Ai digital people: In the process of moving, laser radar can avoid obstacles in real time to ensure that Ai digital people can safely shuttle through various scenes. At the same time, it does not affect the normal operation of ASR and TTS, and users can communicate with Ai digital people at any time when they move to obtain the required information.
3. The hardware specification of Ai digital human advertisement screen supports interactive experience.
Ai digital human advertising display screen: 43-inch TFT LED dual screen, brightness of 700 CD/m, contrast of 1200:1, and viewing angle of 89, which provides a clear picture for information display in the interactive process and helps users understand the content.
Ai digital human advertising screen operating system: Android 5.1 and LINUX dual systems are adopted to ensure the stable operation of ASR, TTS and other interactive functions and navigation systems, and improve the overall interactive fluency.
Ai Digital Man Advertising Screen Network Support: Android WiFi supports dual-band 2.4&5G, which ensures smooth data transmission in the cloud and helps ASR and TTS functions to play efficiently.
4. Multi-scene interactive application of Ai digital human advertisement screen
Museum: Visitors ask Ai digital people about the exhibits through voice. After ASR recognition, the system calls the knowledge base, TTS explains with vivid voice, and displays the pictures and videos of the exhibits on double screens to enhance the interactive effect.
Advertising screen of Ai digital people in shopping malls: customers voice to inquire about the location of goods, promotional activities, etc. Ai digital people use laser radar to navigate and plan routes, and through TTS guidance, dual-screen synchronous display of road maps and commodity information.
Advertising screen of Ai digital people in scenic spots: Tourists voice query about the introduction of scenic spots, tour routes, etc., and Ai digital people respond quickly, providing detailed voice explanation and picture display to enhance the tour experience.
5. Advantages of interactive function of Ai digital human advertisement screen
Real-time: the real-time driving service for the localization and deployment of the advertising screen of Ai digital people, combined with the cloud model, enables ASR identification and TTS response to be completed quickly and reduces the waiting time of users.
Accuracy of Ai digital human advertising screen: Advanced ASR algorithm and rich knowledge base ensure accurate understanding and response to user instructions and reduce interaction errors.
Flexibility of Ai digital human advertising screen: It can adapt to the interactive needs of different scenes, and adjust the voice style and information display mode according to the actual situation to meet the diverse interactive scenes.
