Case Details
Project in brief: Follow Me Hospital AR Navigation overlays intuitive routes onto the live camera view, helping patients and visitors find departments, examination rooms, pharmacies, amenities, and parking areas. Built on EasyAR Mega, the solution combines spatial positioning, AR guidance, voice prompts, and hospital-service integration in a lightweight mini program.
Use case: Indoor and parking-area wayfinding across complex hospitals Access: WeChat or Alipay mini programs, hospital official accounts, on-site QR codes, and registration workflows Core experiences: Live AR routes, voice and distance guidance, route recalculation, safety reminders, queue updates, and care-journey integration
Project Context: Reducing the Friction of Hospital Wayfinding
A hospital visit often requires people to move between registration counters, consultation rooms, examination areas, payment points, pharmacies, wards, and exits. Routes may cross multiple floors and buildings, while unfamiliar terminology, time pressure, and anxiety make signs harder to interpret.
Patients and visitors repeatedly stop to ask for directions, and hospital staff are interrupted by non-clinical wayfinding questions. Sight+ developed Follow Me Hospital AR Navigation to address both sides of this problem: clearer routes for visitors and a more efficient service environment for hospitals.
Solution: One Navigation Layer for the Complete Care Journey
The solution combines high-precision AR navigation with an integrated care-journey workflow. It supports continuous indoor and outdoor positioning, live paths overlaid on the camera view, and navigation between hospital buildings and parking areas. By connecting with hospital information systems, official WeChat accounts, and mini programs, it can guide patients from registration to the correct room and provide queue information along the way.
Scan the hospital's AR navigation mini-program code and begin without installing a separate app.
Open “Hospital Services – Indoor Navigation” from the hospital's official WeChat account.
Use the Indoor Navigation feature in the hospital's WeChat or Alipay mini program.
Enter navigation directly after registration or another care-journey step, with the destination already connected to the task.
Visitor Journey: Search, Locate, and Follow What You See
1. Find the Destination
Users can browse broad categories such as Departments, Registration & Payment, or Wards, then narrow the results with subcategories. They can also enter a keyword in the main search bar. Coverage includes medical destinations—consultation rooms, examination areas, pharmacies, and wards—as well as restrooms, drinking-water points, power-bank stations, and other everyday facilities.
2. Confirm the Starting Position
Once navigation opens, the user points the phone camera at the surroundings. The system recognizes the location and orientation, then displays the route from the current position to the selected destination.
3. Follow Live AR Guidance
A virtual guide and route graphics appear over the live camera view, with voice instructions, distance information, and estimated time. Visitors follow what they see rather than translating a two-dimensional map into corridors, doors, and turns.
4. Respond to Route Changes and Safety Prompts
If a user takes a wrong turn, the system recalculates and displays a new route. When the user approaches an escalator, a reminder asks them to stop looking at the phone for safety; navigation can then resume after they step off. These transitions help the digital route fit the realities of a busy public building.
Implementation: EasyAR Mega as the Navigation Backbone
Follow Me Hospital AR Navigation is built on the EasyAR Mega Spatial Computing Platform. Computer-vision algorithms determine position and orientation in complex indoor environments, while a device-cloud collaborative architecture supports stable routing, localized data updates, cloud services, and scalable deployment.
The platform supports centimeter-level positioning and sub-second initialization for responsive indoor guidance.
A panoramic camera can capture more than 100,000 square meters in two hours, without requiring expensive laser equipment.
Mapped areas can be stitched across very large facilities and updated as departments, routes, or buildings change.
The platform supports a broad range of Android devices, AR/MR glasses, WeChat and Alipay mini programs, Unity, and Unreal Engine.
Project Value: Better Patient Experience and Smarter Operations
For patients and visitors, clear visual guidance reduces uncertainty, unnecessary walking, and repeated requests for help. The same interface can support routine visits, examinations, medication pickup, payment, emergency journeys, and movement between parking areas and clinical spaces.
For hospital staff, self-service navigation reduces interruptions caused by wayfinding questions. For administrators, the backend supports real-time updates to department information, routes, and emergency notifications, keeping guidance aligned with operational changes.
Navigation analytics can also reveal high-traffic areas, commonly used routes, and potential bottlenecks. These observations help hospitals improve layouts and services while building a more coherent digital patient experience. The solution has been deployed in hospitals across Zhejiang, Anhui, Jiangxi, Shandong, and Hebei.
Frequently Asked Questions
Do users need to download an app?
No. Users can scan an on-site QR code, open Indoor Navigation from the hospital's official WeChat account or mini programs, or enter navigation directly after registration and other key steps.
What destinations does the navigation cover?
Coverage can include departments, registration and payment counters, examination rooms, pharmacies, wards, restrooms, water fountains, power-bank stations, hospital entrances, and parking areas.
Is it suitable for people who are not comfortable with technology?
The interaction is designed to be direct: select a destination, point the phone at the surroundings, and follow the visual and voice prompts. Category search, automatic positioning, and route recalculation reduce the number of decisions users need to make.
How does AR navigation differ from signs and two-dimensional maps?
AR guidance places the route directly over the user's live view, reducing the need to match map symbols with real corridors. It can also respond to position changes, recalculate routes, provide safety reminders, and connect navigation with queue and care-process information.
What technology powers the solution?
The solution uses the EasyAR Mega Spatial Computing Platform for large-scale mapping, visual positioning, spatial alignment, cloud-device collaboration, and multi-platform deployment.
