Beyond Area Targets: The Scan-Agnostic Area Targets Alternative That Super-Charges Indoor AR

If you’ve ever watched a demo collapse under the weight of drifting content, you already know the weak link in most XR stacks isn’t your 3D models or your code—it’s the visual-positioning layer. Vuforia Area Targets, ARCore Cloud Anchors, even LiDAR-only scans can choke on changing layouts, multi-floor hand-offs, or low-light shifts, leaving developers to shoulder the blame.

Enter MultiSet’s scan-agnostic VPS: a drop-in system that ingests any point cloud, locks onto a scene in under two seconds, and holds a rock-solid six-centimetre accuracy with sub-centimetre drift—even in live, forklift-riddled warehouses. Backed by the AREA Research Project’s top robustness score and showcased step-by-step by XR expert Joshua Drewlow, MultiSet turns spatial mapping from a fragile dependency into a decisive advantage for every indoor-navigation, location-based training, or asset-tracking build on your roadmap.

Why Your Last Warehouse Demo Drifted Off the Shelves

You finally finished scanning 40,000 sq ft of racking with a LiDAR iPad, baked a Vuforia Area Target, and pressed “Build.” On the big day your picking app localised—then drifted two pallets down the aisle. Everyone blamed “AR.” The truth? The underlying visual positioning system (VPS) couldn’t keep pace with dynamic stock, changing lighting, and a fast-moving handset.

Developers are now Googling “Area Targets alternative” by the thousands because they want centimetre-level reliability without proprietary workflows or re-scans every time someone moves a forklift. MultiSet’s scan-agnostic VPS recently crowned “most robust” in the AREA research benchmark solves exactly that pain.

Why Devs Are Actively Searching for an Area Targets Alternative

1. Proprietary scan & upload loops – Time-consuming bundle generation and size limits.

2. Single-floor caps – No notion of z-stacks or seamless hand-off between floors.

3. Lighting-sensitive meshes – Brightness changes require multiple targets.

4. Cloud-cost surprises – Egress fees for every re-localization call.

5. Stagnant roadmap – PTC’s attention has shifted to other industrial products.

   
   

How AREA Benchmarked Visual Positioning Systems

Earlier this year the 15th AREA Research Project published the first vendor-agnostic head-to-head of enterprise VPS platforms. Their ten-step methodology—starting with defining use-case scenarios and ending with weighted scoring—became the gold standard for AR teams vetting solutions.

The Eight Factors Every XR Team Should Test

AREA recommends scoring each candidate against accuracy, coverage, speed, reliability, integration, performance, scalability, and mapping time.

Developer takeaway: build your own lightweight version of this matrix so non-AR stakeholders can compare apples to apples.

What “Scan-Agnostic VPS” Actually Means

Traditional VPS flows force you to produce their type of scan - often an on-device SLAM pass or a photogrammetry export. MultiSet ingests any point cloud: terrestrial LiDAR (.e57), Matterport, NavVis, laser scans, even BIM-derived meshes. The mapping pipeline re-optimizes features for localization without touching original coordinates, which preserves dimensional accuracy.

MultiSet’s Core Advantages Aligned to AREA Factors

AREA factor	MultiSet highlight	Real-world impact
Accuracy	Median 6 cm lock in dynamic scenes	Precise content overlays for tight-tol pipelines
Coverage	Infinite MapSet stitching across floors	No “teleport” gaps between levels
Speed	2 s cold-start; 1 cm drift after 60 s	Snappy UX even after occlusion
Reliability	Environmental-resistance score 9/10	Survives lighting shifts & clutter
Scalability	Self-hosted option + free tier to 10k calls	Start small, ramp safely
Mapping Time	Import existing scans—no re-walk	Go live in hours, not weeks

Hands-On Demo: Joshua Drewlow’s Setup

Drewlow drags a 280 MB E57 scan into the MultiSet console, hits Generate MapSet, and tests localization on device - all under two minutes. An editor script prints pose.IsLocalised every frame; lock arrives at frame 34.

Tip: Wrap localization in a coroutine so you can surface a progress HUD instead of freezing the render thread.

AREA Benchmark Snapshot: MultiSet vs. Leading VPS

AREA’s head-to-head put MultiSet at 9/10 (accuracy) versus Vuforia’s 8/10 (accuracy) and 9/10 (drift) versus Vuforia's (7/10 (drift). Immersal paled in comparison with 7/10 (accuracy) and 5/10 (drift). Initialization scored 8/10 - slightly slower than a pure on-device map but with far less drift later on.

Anecdotally reviewers noted that MultiSet was “the most robust solution tested, moving between MapSets smoothly”.

Migration Guide: From Area Targets to MultiSet in One Afternoon

Step 1 – Export Mesh: Vuforia Studio ➜ Area Target ➜ Export OBJ

Step 2 – Convert if needed: Use CloudCompare or Blender to convert to PLY/E57 if your original is OBJ.

Step 3 – Import to MultiSet Console: Select Create MapSet → upload mesh. Mapping server automatically sets scale using native units.*

Step 4 – Swap SDK: Remove VuforiaWrapper.dll and install MultisetSDK.unitypackage. Replace ObserverBehaviour calls with LocateAsync().

Step 5 – Validate with AREA quick-tests: Run a 10-point accuracy walk, morning & afternoon, plus an artificial-occlusion pass.

Mapping-time note: AREA scores MultiSet high here because you’re repurposing existing scans, not re-walking the site.

Developer Checklist: Evaluate VPS Solutions the AREA Way

1. Define use case & accuracy target – e.g., < 10 cm for indoor navigation.

2. List criteria – accuracy, startup, robustness, device mix, security, scalability, offline.

3. Prepare a controlled test bay – multiple lighting & clutter variants.

4. Record mapping effort – stopwatch every vendor’s scan/import workflow.

5. Run localisation loops – at least 10 trials per scenario; log drift.

6. Stress network – airplane-mode + low-bandwidth proxies for cloud VPS.

7. Score and weight – build a simple spreadsheet so business owners can see trade-offs.

8. Plan fallback UX – QR code resets or manual map taps, per AREA best practice.

   
   

AREA stresses testing across lighting, weather, and reflective surfaces because localization can tank at dusk or under sodium lamps.

Location-Based AR Training & Indoor Navigation: MultiSet VPS in Action

Joshua Drewlow’s second video, “Location-based AR Training with MultiSet VPS,” lands right at the crossroads of two of this year’s hottest topics - AR indoor navigation and on-the-job XR training workflows. At just under 19 minutes, he walks you through building a dual-purpose Unity app that guides a user through a facility while surfacing contextual SOP pop-ups at each waypoint.

Below, we unpack the flow, call out why MultiSet’s 6 cm accuracy and 1 cm drift matter, and flag optimization tips you can lift straight into your own projects.

1. Scene Setup – Re-using Any Scan

Drewlow opens with a reminder that MultiSet is scan-agnostic: he imports a Matterport-to-E57 warehouse scan, but you could just as easily drop in Leica, NavVis or LiDAR-iPhone point clouds. This is a massive time-save compared with frameworks that require an on-device re-scan every time you reorganize shelving. The pitch-deck data backs the claim—“Works with any 3D scan …” and still delivers a median 6 cm accuracy across all conditions .

2. Generating a Navigation Path

Next comes pathing. Drewlow leverages Unity’s built-in NavMesh plus a lightweight script that converts each nav waypoint into a MultiSet DeviceAnchor. As he hits Play, the map stitches seamlessly across two levels of the facility—no teleport gap, no manual anchor switch—thanks to MultiSet’s MapSet stitching pipeline (scored “✓” under multi-floor support in AREA testing). The video’s real-time console shows TimeToLock: 1.9 s, lining up with MultiSet’s benchmark of < 2 s initialization and the low-drift after 60 s (≈ 1 cm) metric published in the tech-advantage table .

3. Layering Contextual Training Steps

At each waypoint he spawns a canvas panel that walks the trainee through a task—“Scan SKU A-42” or “Inspect coolant valve.” When the user moves beyond the proximity radius, the panel auto-advances, giving the flow a hands-free feel that beats QR-on-the-wall toolchains. This design mirrors the Employee Onboarding and Warehouse Training scenarios MultiSet highlights for enterprise pilots .

Dev tip: Fire an await client.TryLocateAsync() before showing each panel so you can log drift deltas in the background for QA—valuable evidence when you’re defending accuracy targets to stakeholders.

4. Why Accuracy & Drift Make or Break Training UX

Conventional wisdom says a few decimeters of drift is “fine” for navigation. That changes the moment you overlay procedural steps on real-world equipment. If an arrow misaligns by even 15 cm, it can point to the wrong pump or rack bin—confusing at best, dangerous at worst. The 6 cm median accuracy and sub-centimeter drift MultiSet posts under dynamic lighting didn’t just come from an internal lab; AREA’s vendor-agnostic tests crowned the platform the “most robust” performer in warehouse-style environments, specifically praising its ability to hold lock among moving forklifts and shifting pallet heights.

5. Performance Checklist (Borrowed from AREA)

Before you ship an indoor-nav-plus-training app, replicate Drewlow’s checklist against your own facility:

1. Accuracy walk-through – 10 random POIs, morning and evening.

2. Low-light & glare sweep – simulate shift change or emergency lighting.

3. Occlusion test – block camera with a hand for 3 s; expect relock < 300 ms.

4. Waypoint density stress – 100 anchors in a 10 m radius to test update rate.

These mirror the robustness and environmental-variation factors in AREA’s methodology, ensuring your pilot data translates to real operational success .

6. Cross-Industry Use-Case Ideas

• Pharma clean-rooms – wayfinding combined with glove-compatible checklists.

• Aviation MRO – walk-through plus torque-spec pop-ups next to engine bays.

• Retail back-of-house – new-hire picking routes with shrink-control tips.

Because MultiSet supports on-device offline mode and self-hosted deployments, even bandwidth-constrained or air-gapped environments can roll out the same workflow—a critical differentiator for regulated verticals.

7. Next Steps

Clone Drewlow’s repo, drop in your E57 scan, and follow the code exactly as shown in the video. Within an afternoon you’ll have a reproducible demo that nails both AR indoor navigation and location-based AR training—fully backed by enterprise-grade accuracy, low drift and robustness.
