Augmented Reality (AR)
Instructions that appear on the equipment itself.
Overlay the right information on the physical task. We build AR for devices people already carry or for see-through headsets, align it precisely to real objects and connect it to the systems that keep instructions current.
The opportunity
Start with a decision
worth improving.
An inspector checks a pump against a maintenance checklist. AR highlights each inspection point on the equipment and records readings against the asset without paper.
From possibility to a working system
Follow the flow.
Three connected decisions. One considered architecture.
Conceptual flow, not a live system or measured result.
Pick the device
Compare phones, tablets and see-through headsets for the task. Hands-free work favors headsets; occasional use and wide distribution favor the devices people already carry.
Align to the object
Register content to the real asset with image targets, object tracking or spatial anchors. Test drift, lighting and occlusion in the actual environment, not only in the office.
Keep content current
Link overlays to maintenance systems, manuals and asset records so updates flow without rebuilding the app. Capture readings and photos back against the asset.
The work, made concrete
What we can build
with your team.
We agree scope, dependencies and acceptance criteria before delivery. Your project can start with an assessment, a pilot or an integration into an existing system.
Device and tracking assessment
Clarify the system boundary, the responsible owners and the decisions the architecture needs to support.
An object-aligned AR pilot
Turn the agreed design into reviewable work, evaluated against representative inputs and explicit success criteria.
A content pipeline linked to asset data
Make the next step operable: document responsibilities, known limitations and the path from pilot to ongoing use.
In depth
Go deeper into AR on the job
Two decisions shape most field AR projects: which remote assistance platform to buy, and which tracking method will keep content on the equipment.

Five AR overlay patterns and what each one depends on
Most industrial AR falls into a handful of patterns. Naming the pattern early tells you what data, device and alignment work the project really needs.
| Pattern | What the worker sees | Data it draws on | Usual device | Alignment needed |
|---|---|---|---|---|
| Guided work instructions | The next step, highlighted on the part it concerns | Procedures, torque values and part lists from engineering or maintenance | Headset for long two-handed jobs, tablet for short ones | High: content must land on specific components |
| Inspection rounds | Each inspection point marked on the asset, with a field for the reading | Inspection plans and asset records, plus limits for each reading | Phone or tablet, often in a rugged case | Medium: points must be unambiguous, not millimeter-exact |
| Remote expert annotation | Marks drawn by a distant specialist, pinned to the equipment | The work order, asset history and whatever the expert shares | Phone first, glasses for daily users | Medium: annotations must stay on the object as the camera moves |
| Indoor wayfinding | Arrows and labels leading to a room, asset or muster point | Floor plans, asset locations and access rules | Phone | Low to medium: depends on how dense the destinations are |
| Product visualization | A full-size product placed in a real room or on a plinth | Sales configurations and simplified 3D models | Phone or tablet, often in a web browser | Low: a floor or table plane is usually enough |
One application can combine patterns, for example an inspection round that opens a remote session when a reading is out of range. Plan the data for each pattern separately.
Writing work instructions for an overlay rather than a page
A procedure written for a binder rarely works when it floats beside a machine. Paper procedures bundle several actions into one numbered step, put warnings in a box at the top and assume the reader can glance back. In AR, each step should ask for one physical action, point at exactly one place and say how the worker will know it is done, such as a click, an indicator turning green or a gauge reading inside a band.
Put cautions where the hazard is: a warning about stored pressure belongs on the valve before the step that opens it, not on a title card the worker dismissed ten minutes earlier. Use the labels physically printed on the equipment, not the names in the engineering model, so the screen and the machine agree. Keep text short enough to read at arm's length while wearing safety glasses.
Decide which steps need evidence. A photo of a seated connector or a typed reading captured at the step, stamped with the user and time, is far more useful to quality and maintenance teams than a signature at the end of the job. That evidence should be written back to the asset record, which ColdAI's AR work treats as part of the content pipeline rather than an afterthought1.
How an AR procedure stays in step with the asset record
- Asset record
The maintenance or asset system holds the equipment's identity, history and current configuration.
- Procedure revision
Engineering or maintenance updates the procedure in its own system of record.
- Published overlay
The AR app pulls the approved revision and maps each step to a place on the asset.
- Field execution
The technician follows the overlay, with alignment checked against the real equipment.
- Readings and photos
Step-level evidence is written back against the asset, with user and timestamp.
Designing AR for gloves, glare, noise and weak signal
Field conditions defeat more AR pilots than technology does. Check each item on site with the people who will use the app.
Safety hazards an overlay can introduce on the shop floor
Content blocks the view of a real hazard
Early signalWorkers lift or tilt the device to see past an overlay near moving parts or edges.
MitigationKeep overlays out of the walking path and away from moving machinery, and fade content automatically while the user is moving.
Attention tunnels onto the screen
Early signalNear misses with vehicles, trip hazards or colleagues during AR use.
MitigationBan AR use while walking in traffic routes, keep steps short and include situational awareness in the risk assessment for each task.
Workers over-trust alignment
Early signalA wrong component is worked on because the overlay pointed at it.
MitigationDesign steps so the worker confirms the part by its label or shape, and keep independent verification for safety-critical actions.
Stale content looks authoritative
Early signalThe overlay shows a superseded torque value or step order.
MitigationDisplay the procedure revision on screen and block content whose cached revision is older than the published one.
Frequently asked questions
Does augmented reality work outdoors in bright sunlight?
It can, with limits. Phone and tablet screens suffer glare, and see-through headset displays can wash out in direct sun, which makes faint content hard to read. Camera-based tracking also changes with harsh shadows and reflections. Test outdoors at the brightest time of day, design high-contrast content and consider shading accessories or tinted visors where the device supports them.
Can existing PDF manuals be turned into AR work instructions?
They are a good source, but rarely usable as they are. Each manual step usually has to be split into single actions, linked to a location on the equipment and given a completion check. The safer route is to restructure the procedure once in the system that owns it, so the PDF and the AR version come from the same revision instead of drifting apart.
How does an AR app connect to a maintenance management system?
Through the maintenance system's APIs, scoped to the work the user is doing. The app reads the work order, the asset's attributes and the approved procedure, then writes readings, photos and step completions back under the user's identity. Keep the maintenance system as the source of truth and avoid copying its data into the AR application, so a change made in one place appears everywhere.
Should AR on phones be built as a web app or a native app?
A browser-based app is easiest to distribute, since a link or QR code is enough, and suits simple placement or visualization. Native apps give fuller access to tracking features such as image and object recognition, offline storage and device management. The runtime comparison sets out the trade-offs in detail.
Who should maintain AR content after launch?
The team that owns the underlying procedure or asset data should own the content, with a named person responsible for the AR mapping of each asset type. When the source procedure changes, the AR version should update from it automatically or be flagged for review. Content that nobody owns falls behind the official version within months and quickly loses the trust of the people using it.
