PWR-220 · SUPERVISED full tutorial
Use augmented-reality guidance in a controlled task and recover safely when the display is wrong or absent
This lesson teaches the provider-controlled AR method: set a narrow task, capture an unaided baseline, verify registration, follow one cue at a time, cross-check the physical task, log misleading cues, test display-off performance and rehearse a safe failure response. It does not teach clinical, driving or industrial AR use.
What you will produceThe learner and qualified trainer complete a versioned low-consequence AR simulation record with physical-task errors, cue errors, workload, display-off retention and a demonstrated stop-and-fallback response.

Full step-by-step individual tutorial · TLU-PWR-220
The learner and qualified trainer complete a versioned low-consequence AR simulation record with physical-task errors, cue errors, workload, display-off retention and a demonstrated stop-and-fallback response.
Prepare questions, learn the cue legend and use a provider-approved benign simulation.
Pause on a conflicting cue and compare it with the approved physical reference.
Report workload, visual discomfort and whether guidance is worth its setup burden.
Qualified help is required for
Device fitting, visual assessment, registration tolerance and task progression.
Any clinical, industrial, driving, street, machinery, heights or safety procedure.
Judging whether an AR cue can replace a regulated instruction, instrument or qualified check.
Never do this from the page alone
Follow a digital overlay when it conflicts with the physical object, approved procedure or supervisor.
Use a headset near traffic, stairs, tools or moving equipment outside the controlled pathway.
Claim display-off competence from fast guided performance.
2 · Get ready
Gather what you need and check the starting conditions
What you need
Provider-approved AR device, software/overlay version and benign simulation such as arranging four labelled blocks.
The supplied authoritative physical task card says: on a four-by-four tabletop grid put foam A at row 1 column 1, B at row 2 column 1, C at row 2 column 2 and D at row 1 column 2, in A-B-C-D order. The trainer's guided trial intentionally shifts only the C arrow to row 3 column 2; the printed card remains authoritative. Use an unobstructed surface with no sharp, hot, powered or hazardous objects.
Error log, workload and discomfort scales, display-off fallback card and observer checklist.
Before you start
Record vision needs, eyewear, migraine/seizure or motion-sensitivity concerns, current symptoms and preferred display format with the provider.
Lock device fit, overlay version, registration target, lighting, task layout and maximum exposure time.
Agree the stop gesture and the rule: if overlay and physical reference disagree, stop and use the reference or supervisor.
3 · The method
Follow these steps in order
Define the guided task
Name one benign task and the exact outcome, such as placing four labelled blocks in sequence; list all excluded real applications.
Why: A narrow task keeps guided performance from being called expertise.
Check: The card names the object set, overlay, version, setting, error measure and non-uses.
Capture a physical-card baseline
Complete the task once from the approved physical card with the display off; record order errors, time and workload.
Why: This separates ordinary task knowledge from overlay assistance.
Check: A raw baseline exists before the AR demonstration.
Learn the cue legend
While stationary, identify every arrow, colour, warning and completion mark and explain which physical source overrides it.
Why: Misread graphics can create confident wrong action.
Check: The learner interprets all cues and names the stop-on-conflict rule.
Verify registration
Align the overlay to fixed markers and check it from each provider-approved viewing position before touching an object.
Why: A shifted overlay can point to the wrong part even when software runs normally.
Check: All cue markers sit within the provider-set tolerance or the trial is cancelled.
Follow one cue, then verify
For each step, read the overlay, compare it with the physical task card or labelled object, act once and confirm the result before the next cue.
Why: One-at-a-time checking limits cascades from a wrong or skipped cue.
Check: Every action has a cue, physical check and result in the log.
Log misleading and missed cues
When a cue is late, hidden, shifted or wrong, stop and mark its type instead of correcting silently.
Why: Silent correction makes the system look more reliable than it was.
Check: Cue failures remain distinct from learner action errors.
Test display-off performance
After a rest, remove the display and use a new arrangement of the same four blocks; score completion without old overlay positions.
Why: Immediate guidance can improve performance without teaching the sequence.
Check: Display-on and novel display-off errors are reported separately.
Rehearse safe display failure
The provider blanks or freezes the display while the learner’s hands are away from objects; the learner stops, removes or parks the device and uses the approved card or supervisor.
Why: Failure handling is part of augmented capability.
Check: The learner reaches the declared safe state without guessing or continuing.
Decide use, adapt or reject
Compare task errors, cue errors, time, workload, discomfort and display-off retention; state whether benefit justifies the burden.
Why: A fast result with high workload or misleading cues may be a poor configuration.
Check: The decision includes version, task, provider and a new-baseline trigger.
4 · Worked example
See the whole method used once
Scenario
A trainer uses AR Overlay 2.1 to guide placement of four foam blocks—A, B, C and D—on a tabletop grid; the physical card is the authoritative source.
Walkthrough
The learner completes a card-only baseline with one B/C swap in 78 seconds and workload 3/10.
After cue training and registration, the learner completes the guided task in 54 seconds but catches one shifted arrow by comparing it with the block label.
The trainer records the shifted arrow as a system cue error, realigns the device and repeats only that step.
After rest, the learner completes a new display-off layout in 74 seconds with no order error, then stops and switches to the card when the trainer safely freezes the display.
Result
AR improved immediate speed and the learner handled one cue conflict and one simulated failure. The result remains a foam-block simulation and does not establish retained procedural, clinical or industrial competence.
5 · Right and wrong
Compare correct or safer execution with the common wrong version
Right and wrong comparison
Moment
Right / safer
Wrong / riskier
Why it matters
Overlay conflict
Stop and follow the approved physical reference or supervisor.
Trust the overlay because it looks precise.
Registration or source errors can make a convincing cue wrong.
Measuring learning
Use a novel display-off task after rest.
Call the fastest display-on attempt retained skill.
Guidance-on performance and learning are different outcomes.
Cue failure
Record late, hidden, shifted and wrong cues separately.
Attribute every failure to the learner.
System reliability cannot be estimated when cue errors are erased.
Progressing decision point
Change one benign task feature after stable registration and fallback.
Move directly to a consequential real procedure.
A simulation does not confer authority or safety in a new domain.
6 · Common mistakes
Spot the error and apply the correction
Common mistakes and corrections
Mistake
Fix
Acting on AR cues after registration has drifted.
Recheck fixed markers after fit, lighting or viewing-position changes and cancel out-of-tolerance trials.
Following an AR overlay without checking the physical source.
Require a physical-source check before each action and stop on conflict.
Averaging guided and unaided AR trial results together.
Keep separate scores and never average guided and unaided trials.
Cue error blamed on the user
Use distinct fields for system cue, interpretation and physical action errors.
Triggering AR display-loss rehearsal while hands remain engaged.
Simulate display loss only from a provider-chosen safe pause with hands clear.
7 · Practice
Turn the steps into a usable skill
First session
Record the card-only baseline and the exact AR configuration.
Learn cues and verify registration from each allowed position.
Complete one guided four-block task, logging system and action errors separately.
Repair only the largest cue or registration failure and repeat the matched step.
After rest, run a novel display-off task and the provider-controlled failure response.
Repeat plan
The provider controls exposure time and frequency. Retest the same version on a new benign arrangement after at least 48 hours; rebaseline after device, software, registration, lighting, object or task changes.
Progress when
Registration remains within the provider-set tolerance throughout the task.
Physical-task errors improve without a rise in misleading-cue errors, discomfort or workload.
Novel display-off performance and stop-on-failure behaviour meet the declared rule.
Do not progress when
Blur, eyestrain, headache, nausea, dizziness, disorientation, seizure warning or loss of balance occurs.
The learner follows an overlay despite a conflict or cannot notice display freeze.
The proposed task is clinical, industrial, driving, traffic-facing or otherwise consequential.
8 · Check the result
Measure what changed
Errors and failure handling in one versioned benign AR task
How: Count physical action errors, late/hidden/shifted/wrong cues, completion time, workload, symptoms, novel display-off errors and success of the safe fallback.
Good result: A good result has no unhandled cue conflict, improves or maintains physical accuracy, meets the provider’s workload/comfort rule and demonstrates display-off fallback twice.
This does not prove: It does not prove expert vision, clinical competence, safe real-procedure performance, patient benefit or broad transfer.
Self-check
Can you name the physical source that overrides the overlay?
Can you separate one cue error from one action error in the log?
What changed between the display-on and novel display-off trials?
Can you demonstrate the display-failure safe state before handling objects?
9 · Stop, adapt or get help
Keep the safety boundary practical
Stop and get help
Stop for visual pain, new blur, headache, nausea, dizziness, seizure warning, disorientation or balance loss.
Stop when registration cannot be verified, the display freezes, the authoritative reference is unavailable or supervision is lost.
Seek qualified visual, clinical, occupational or device review before any consequential use or after a new symptom.
Accessibility and adaptations
Provide the physical task card in large print, high contrast, audio or tactile labels; it remains authoritative.
Adjust display scale, contrast and dwell time through the provider rather than demanding faster responses.
Use a seated tabletop simulation and short exposure blocks; keep prescribed eyewear and other aids.
