I. Background: Solving the Headache of Maze‑Like Exhibition Venues

SightPlus, a six‑year veteran of spatial computing, brought collaborative MR/AR experiences to WAIC 2024. Yet its real showstopper was the world’s first venue-wide AR navigation mini-program, based on VPS (Visual Positioning System) with centimeter-level accuracy. Designed to tackle the perennial pains of large-venue events—navigating across buildings, finding booths, and meeting up with people—it gave tens of thousands of attendees a lightweight AR navigation experience that required no download, right on WeChat.

Large exhibitions are notorious for sprawling floor areas, multiple buildings, makeshift structures, and dead GPS signals indoors. Traditional 2D maps are abstract and confusing; exhibitors struggle to guide visitors straight to their booths; and attendees waste ages trying to find each other. SightPlus built this solution on its in‑house EasyAR Mega spatial computing platform, packaged as a WeChat mini‑program, and stress‑tested it live at WAIC, creating a replicable blueprint for smart navigation in large public spaces.

II. The Solution: Your All‑in‑One Navigation Toolkit for WAIC

Built as a WeChat mini‑program, the tool requires no installation—simply scan a QR code to access AR navigation, exhibit reservations, virtual check‑ins, and more. It’s a complete spatial computing toolkit for exhibitions, malls, and large venues.

Core Features

Cross‑Building Live AR Navigation

Seamlessly bridging indoor and outdoor spaces between the World Expo Center and the Expo Hall, the system overcomes the recognition challenges posed by temporary exhibition structures. With centimeter‑level accuracy and sub‑second response, users simply point their phone camera, and virtual guidance paths overlay the real‑world view. You can search across all floors for any booth, restroom, service point, or dining area, making navigation fluid and foolproof while eliminating the classic confusion of “which floor am I on?” and “am I inside or outside?”

Real‑Time Location Sharing & People‑Finding

Share your booth or current location with a single tap. Generate a shareable code—others scan it and get direct AR navigation straight to you, cutting the hassle of coordinating meet‑ups in huge halls. Exhibitors can also share their mini‑program codes, letting visitors navigate to their booths with one click and driving more foot traffic their way.

AI Digital Human Guide & Personalized Services

The digital human assistant recommends activities based on your interests, personalizing your event experience. It also integrates reservation booking for metaverse exhibits and AR virtual photo‑op check‑ins—weaving together “find your way → book experiences → interactive fun” into a seamless journey.

Technical Specs

Positioning: VPS‑based, centimeter‑level accuracy, sub‑second response, and robust motion‑tracking.
Deployment: Supports private and hybrid cloud deployments, adaptable to dynamic, temporary exhibition spaces.
Platform: WeChat mini‑program, fully compatible with Android and iOS—no hardware changes, no app downloads, ultra‑low user friction.

III. The Computing Backbone: EasyAR Mega Powers Metaverse Spatial Computing

The WAIC digital human AR navigation runs on SightPlus’s EasyAR Mega, an edge‑cloud spatial computing platform designed for large‑scale scenarios—cities, parks, exhibition venues, and shopping districts. By leveraging VPS, it creates a high‑precision digital twin of the physical world, serving as the underlying infrastructure for large‑space AR applications.

Unlike traditional GPS or Bluetooth, EasyAR Mega doesn’t rely on satellite signals. Instead, it matches real‑time camera imagery in the cloud against pre‑built 3D point‑cloud maps, computing the user’s 6DoF spatial pose in the real world. This enables unified, persistent indoor‑outdoor positioning, solving the age‑old problem of GPS dropout indoors.

The platform boasts three core capabilities:

Large‑Scale Automated Mapping: Supports multi‑device data collection, reconstructs millions of square meters of space, and offers incremental updates that adapt to temporary structures and dynamic venue changes.
Robust Positioning in Complex Environments: Maintains stability under crowded conditions, variable lighting, and moving object interference, and has proven reliable even during peak foot traffic.
Cross‑Platform Toolset: Makes its capabilities available to mini‑programs, mobile apps, and AR/MR glasses, enabling rapid development of AR navigation, cultural tour guides, digital human services, and spatial interactions. With over 200,000 developers globally, 40% of whom are from overseas, the platform has delivered flagship projects at tourist attractions such as Shanghai Yu Garden, airports including Chengdu Tianfu International Airport, hospitals like Shanghai Renji Hospital, and museums. It was selected by five Chinese ministries—Industry and IT, Education, Culture and Tourism, Radio and TV, and Sport—as a 2023 Pioneer Application Case in Virtual Reality, and in April 2026, it was named a 2025 Exemplary Metaverse Case by four national departments, making it the only Shanghai‑based technology tool winner.

IV. Real‑World Impact: What Surprises Did This AR Navigation Bring?

User Experience: For attendees, paper maps and flat digital floor plans are history. With live AR guidance, routes are intuitive and instantly understandable, slashing time spent hunting for booths, facilities, or contacts—making the entire show visit smoother and more enjoyable.

Event Operations: Organizers get a powerful digital tool that handles exhibit reservations, visitor flow guidance, and user engagement in one place, raising the event’s digital service standards.

Replicability: Packaged as a mini‑program, the solution is simple to deploy and low‑fuss. This AR navigation isn’t just for AI conferences—it flexibly adapts to large expos, tourist attractions, airports, hospitals, shopping malls, and any complex, sprawling public space.

V. Outlook: Unlocking the Next Frontier in Spatial Navigation

Spatial computing is moving from XR‑glasses‑only experiences to widely accessible mobile mini‑programs, and AR navigation is the killer entry point. SightPlus will continue evolving the EasyAR Mega platform, refining positioning accuracy in challenging scenarios, enhancing AI digital human interactions, and bringing proven exhibition‑grade AR navigation to more public spaces. With VPS at its core, navigation won’t just be about pointing the way—it will fuse AI commentary, AR content check‑ins, and commercial service discovery, blending physical spaces with digital information seamlessly. This fusion will drive digital transformations across more offline venues, unlocking the commercial and public‑service value of the spatial internet.
