AIbase Report Recently, Shenzhen Metro officially launched the intelligent guide dog "Xiaosuan" at the Huangmugang transportation hub as a pilot project, providing visually impaired passengers with a new technological travel assistance service. This innovative measure is a first in the global rail transit industry, marking the deep application of artificial intelligence technology in the field of barrier-free travel, and demonstrating the warm power of technology for good.

Technical Highlights: Integrated cutting-edge AI, comprehensive and powerful functions

The intelligent guide dog "Xiaosuan" integrates multiple advanced artificial intelligence achievements, including multimodal 3D voxel neural network composite sensing technology, an integrated indoor-outdoor control system, and a visual language large model. Through simple voice commands, the device can activate multiple core functions:

- Path planning and precise navigation: Automatically calculates the best route and guides passengers safely and efficiently to their destination.

- Intelligent obstacle avoidance and blind path tracking: Real-time environmental perception to avoid obstacles and strictly follow the blind path.

- Voice interaction and visual recognition: Supports natural language communication, identifies signs, elevators, and other facilities, and provides real-time prompts.

- Automatic return: After use, a single voice command allows the device to return to the charging station on its own.

These features enable visually impaired passengers to travel more independently and confidently within the metro hub, significantly improving convenience and safety.

Pilot Deployment: Safety First, Gradual Promotion

Currently, the "Xiaosuan" service point is set up near the accessible vertical elevators at entrances 13 and 14 of the Huangmugang hub, mainly covering an area of about 88,000 square meters outside the metro gates. The equipment has passed strict safety testing and on-site verification.

To ensure a smooth transition, during the first month of trial use, dedicated personnel will assist visually impaired passengers in using the device, providing full-time safety assurance. After the successful pilot, it will operate fully automatically and gradually expand to other high-traffic stations in Shenzhen Metro, building a more complete rail transit accessibility network.

User Feedback: Technology Brings Warmth and Independence

Early users have given positive feedback. One visually impaired passenger said, "It's like my eyes; it takes me wherever I want to go." Another user praised its focus and reliability, which are higher than traditional methods, truly reflecting the warmth of "technology for accessibility."
