Implementation

For many people, getting lost in a hospital is a familiar and frustrating experience. You manage to get your registration sorted, only to find yourself wandering between information desks and floors, unable to locate the right consultation room. After your appointment, the doctor sends you for tests—but as you walk out, you can’t remember where the examination room is, and you end up asking for directions again. Then comes the final twist: you lose your way heading out. It’s absolutely exhausting. Besides, staff are constantly interrupted to answer wayfinding questions, which adds to their non-clinical workload—a lose-lose for both sides.

Sight+ recognizes the core challenges that both patients and hospital staff face in traditional wayfinding. The company has developed a targeted AR navigation solution for hospitals called “Follow Me Hospital AR Navigation”, which is powered by its proprietary EasyAR Mega Metaverse Spatial Computing Platform. Leveraging augmented reality (AR), high-precision spatial positioning, and cloud-based architecture, the solution introduces an intelligent navigation model that addresses the common hassles of traditional hospital wayfinding.

Core Features: AR Live Navigation for a Seamless Hospital Journey

Designed for simplicity and intuitiveness, Follow Me Hospital AR Navigation takes the guesswork out of hospital wayfinding. Its core features are built around two primary modules: “High-Precision AR Navigation” and “Integrated Care Journey Workflow”. On the navigation front, the system enables seamless indoor-outdoor positioning transitions, live AR path display, and integrated navigation that covers both indoor hospital areas and parking lots, helping users reach their destinations quickly. On the workflow side, by integrating with hospital information systems (HIS), WeChat official accounts, and mini-programs, the system can automatically guide patients to their consultation room and update them on their queue status after registration, creating a streamlined, end-to-end experience.

Patients and visitors can use the navigation without downloading a separate app. There are several easy ways to access it:

• Scanning a QR code on-site for the hospital’s AR navigation mini-program;
• Accessing the “Hospital Services – Indoor Navigation” menu on the hospital’s WeChat official account;
• Using the “Indoor Navigation” feature within the hospital’s WeChat or Alipay mini-programs;
• Getting redirected to the navigation page automatically from steps such as registration.

To locate a destination, the mini-program supports both category browsing and quick search. Users can filter by broad categories such as “Departments”, “Registration & Payment”, or “Wards”, then refine their search with subcategories like “Emergency” to pinpoint specific locations within a given area. A prominent search bar at the top of the main interface also allows users to enter keywords for instant results. The navigation covers the entire hospital—not just medical areas like departments, registration desks, pharmacies, and wards, but also everyday facilities like restrooms, water fountains, and power bank stations.

Getting started is easy. Once inside the navigation, users simply point their phone at the surroundings, and the system pinpoints their position in real time. A virtual avatar then appears on the live camera view, providing clear directions and distance information to any destination—whether it’s a department, examination room, pharmacy, or restroom. In addition, when users approach an escalator, a safety reminder automatically pops up: “For your safety, please stay off your phone on the escalator.” After getting off the escalator, users can tap to continue without missing a beat. If users take a wrong turn, the system instantly recalculates and shows a new route—along with a “Route recalculated” prompt. It’s truly a “follow what you see” experience.

This visual AR approach changes the game. Instead of reading signs or stopping to ask for directions, patients can simply follow the arrows on their screen and find their own way. It reduces the risk of getting lost in sprawling hospital complexes, alleviates the guidance burden on medical staff, and provides the technological foundation for smarter hospital services.

Technology Backbone: EasyAR Mega Enables Precise Navigation

Currently, Follow Me Hospital AR Navigation has been deployed in hospitals across multiple provinces in China, including Zhejiang, Anhui, Jiangxi, Shandong, and Hebei, earning consistent praise from both users and hospital administrators for its accuracy and thoughtful design. The system provides clear voice guidance with real‑time distance and time updates. Its positioning is remarkably accurate, to the point where it can even remind users to go through security checkpoints, so they reach their destination without hassle. No more getting lost in the hospital. Moreover, the system supports end-to-end care journey integration, and more features—such as registration, consultations, medication pickup, and payment—are on the way.

The stable performance of Follow Me Hospital AR Navigation is underpinned by a robust technology stack. Leveraging its proprietary EasyAR Mega Spatial Computing Platform, Sight+ employs cutting-edge AR and computer vision algorithms to deliver precise positioning and reliable navigation within complex hospital environments. The platform delivers centimeter-level accuracy and sub-second initialization, handling everything from hospitals and airports to parking garages with ease. With a device-cloud collaborative architecture, it ensures long-term navigation stability and accuracy for a smooth user experience. The platform also ensures localized data updates, reliable cloud services, and flexible scalability—all while maintaining strong backward compatibility and smooth upgrades. The platform is built for large‑scale spatial mapping. Without the need for expensive laser equipment, a single panoramic camera can cover over 100,000 square meters in just two hours. It also supports stitching across areas exceeding millions of square meters, producing high‑definition models that are easy to update and expand. Additionally, the platform is compatible with more Android devices than any other, supports major AR/MR glasses, and runs on WeChat mini-programs, Alipay mini-programs, and popular 3D engines like Unity and Unreal Engine—without any performance trade-offs. With its open interfaces and ecosystem, the platform provides a solid technological foundation for hospital AR navigation solutions.

Two-Way Empowerment: Smarter Hospitals, Better Patient Experiences

The deployment of Sight+ Hospital AR Navigation delivers tangible benefits to both patients and healthcare institutions, creating a win-win outcome. One patient commented: “This navigation has made things so much easier. I just pull out my phone and follow the directions to wherever I need to go—paying fees, seeing the doctor—it’s all hassle-free. I no longer waste time and energy trying to find my way.” For hospital administrators, Sight+ provides a comprehensive backend management system that enables real-time updates to departmental information, navigation routes, emergency notifications, and more, ensuring data accuracy and timeliness. The system also includes analytics that let administrators see how patients and visitors move through the hospital—which areas get the most traffic, which routes are most used, and where bottlenecks occur. These insights help optimize layouts and services, making the hospital more efficient and responsive. The AR navigation also gives the hospital a more tech‑forward image and helps it move toward smarter services. Patients benefit across the board—whether they’re coming in for a routine visit, a diagnostic test, or an emergency—and they can find their way with ease, which makes for a much better experience.

Sight+ has a deep understanding of healthcare settings and the challenges patients face, and has created a dedicated AR navigation and service solution for hospitals. The solution removes the uncertainty of hospital wayfinding for patients and reduces unnecessary questions for staff. It also gives hospital administrators the data and tools they need to manage operations more effectively. Looking ahead, Sight+ will continue to refine its AR navigation technology and services, driving high-quality development in the smart healthcare sector and harnessing technology to better safeguard public health.
