Learn wearable navigation cues on a protected route while keeping the established mobility method in charge
A mobility professional introduces four wearable cues on a protected six-metre route while the learner’s ordinary cane remains primary. Map each cue, preview the doorway and foam obstacle, count misses and false alerts, and recover from a staged device failure. Performance on this route cannot establish independent or public navigation.
What you will produceWith an orientation-and-mobility professional, the learner maps cues, travels a short controlled route using ordinary aids, counts missed and false alerts and demonstrates failure recovery.

With an orientation-and-mobility professional, the learner maps cues, travels a short controlled route using ordinary aids, counts missed and false alerts and demonstrates failure recovery.
Participant choice — Select and inspect the route: The professional walks the route, removes uncontrolled hazards and marks start, doorway, foam obstacle and finish.
Learner failure role — Inject one failure: Silence or delay one cue under professional control; the learner stops and continues only through the established mobility method.
Wearable navigation outcome review may inspect “Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption” under the configured comparator.
Qualified help is required for
Team-owned gate — Set the cue hierarchy: Agree that cane contact, direct perception and the professional’s stop command override the wearable; uncertainty means stop.
Provider-controlled rehearsal — Learn cues while stationary: Present left, right, stop and obstacle in random order with immediate correction.
Scheduling owner for Wearable navigation: the responsible team. Repeat rule: The orientation-and-mobility professional sets dose. Start with up to 12 stationary cues and two route passes with rest; repeat on the approved route and change only one feature when error and workload criteria are met.
Never do this from the page alone
Unsafe Wearable navigation choice: Learn cues first on stairs, streets or an unknown corridor.
Second failure that ends progression: Raise audio until all cues are impossible to miss.
Solo use is barred for Wearable navigation. Trigger: Stop for cue conflict, repeated false or missed alert, sound masking, battery/network warning or device shift.
2 · Get ready
Gather what you need and check the starting conditions
What you need
Declared Wearable navigation fixture: A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane.
Setup aid for Set the cue hierarchy: Check battery, network, permissions, cue audibility and emergency contact before movement.
Wearable-navigation provider sheet: from “Navigation aid for blind persons by visual-to-auditory sensory substitution: a pilot study”, extract cue channel, route and support. From the EyeCane study, extract obstacle target, sensor failures and error conditions. Use the WHO/UNICEF report to record the learner’s goal, ordinary cane and preferred fallback. The mobility professional—not either paper—selects this protected route and progression.

See the whole method used once
Scenario
A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane.
Walkthrough
The professional documents the six-metre route and confirms there are no drop-offs or public traffic.
The learner identifies 11 of 12 stationary cues, corrects one left–right reversal and teaches back “stop on conflict.”
Using the cane alone, the learner finishes in 42 seconds with no contact.
With wearable plus cane, one false obstacle cue causes a controlled stop; the route takes 50 seconds with no collision.
The professional stages a silent cue before the doorway; the learner detects uncertainty, stops and locates the doorway with the cane.
Workload is 2/4 and the learner chooses more controlled practice, not removal of the cane.
Result
The learner interprets the small cue set and recovers from a staged failure on one protected route. It does not establish independent or public navigation.

7 · Practice
Turn the steps into a usable skill
First session
Protected wearable route visit: A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane.
Cane-first cue hierarchy: Set the cue hierarchy: Agree that cane contact, direct perception and the professional’s stop command override the wearable; uncertainty means stop.
Stationary four-cue check: Learn cues while stationary: Present left, right, stop and obstacle in random order with immediate correction.
Ordinary-aid route comparator: Preview with the established aid: Travel the route once with the cane and professional, without relying on wearable cues, to establish time and obstacle contacts.
Silent-cue recovery: Inject one failure: Silence or delay one cue under professional control; the learner stops and continues only through the established mobility method.
Repeat plan
The orientation-and-mobility professional sets dose. Start with up to 12 stationary cues and two route passes with rest; repeat on the approved route and change only one feature when error and workload criteria are met.
Progress when
Route geometry and excluded hazards are documented.
The learner teaches back the hierarchy.
Cues are detectable without masking critical sound or causing discomfort.
No severity-weighted collision occurs, conflicts trigger a stop, missed and false cues do not rise, critical sound remains available and the learner chooses continued use.
Do not progress when
Do not continue while this error remains: Learn cues first on stairs, streets or an unknown corridor.
Pause until this correction works: Stop and use the established method.
This Wearable navigation stop ends the block: Stop for disorientation, pain, dizziness, sensory overload, unsafe fatigue or loss of balance.
How: Configured fixture: A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane. The provider logs “Set the cue hierarchy”, every “Preview with the established aid” result, the “Inject one failure” response and Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption. For every route attempt, identify cane use, verbal cueing, contact guarding, missed or false wearable alerts and any dizziness or skin issue; interpret speed only beside this support record.
Good result: No severity-weighted collision occurs, conflicts trigger a stop, missed and false cues do not rise, critical sound remains available and the learner chooses continued use.
This does not prove: Boundary for Wearable navigation: “Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption” describes only A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane. It cannot establish “A smart wearable guarantees independent navigation”.
Self-check
Without the example, demonstrate: Route geometry and excluded hazards are documented.
Find the fault in this attempt: “Learn cues first on stairs, streets or an unknown corridor.” Apply “Begin stationary and then on a controlled route.”; what changes?
What evidence in the completed record shows that this is wrong: “Follow the wearable when it conflicts with direct safety information.”?
Wearable navigation stop decision: Stop for disorientation, pain, dizziness, sensory overload, unsafe fatigue or loss of balance.
9 · Stop, adapt or get help
Keep the safety boundary practical
Stop and get help
Stop for disorientation, pain, dizziness, sensory overload, unsafe fatigue or loss of balance.
Stop for cue conflict, repeated false or missed alert, sound masking, battery/network warning or device shift.
Do not move to streets, stairs, crowds, traffic or unsupervised routes from this lesson.
Accessibility and adaptations
Use vibration, speech, tones or visual cues chosen with the learner and professional.
Shorten the route, add tactile landmarks or use seated map rehearsal while preserving the failure and fallback checks.
10 · Evidence and limits
Why these instructions are here
primary research
Registered support for Wearable navigation: “Navigation aid for blind persons by visual-to-auditory sensory substitution: a pilot study”. It bears on Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption inside the Wearable navigation fixture. It does not validate “A smart wearable guarantees independent navigation”.
Constraint for Wearable navigation, drawn from “Blindness and the Reliability of Downwards Sensors to Avoid Obstacles: A Study with the EyeCane”: Low steps were poorly detected, device-only travel produced more collisions in one pilot, and glove travel was slower than cane use.
WHO/UNICEF context for Wearable navigation: provision follows the user’s goal, “Select and inspect the route”. Support and alternatives must precede reading Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption.
Wearable navigation boundary: interpret “Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption” only for A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane.
A successful result does not establish “A smart wearable guarantees independent navigation”.
Wearable navigation limiting finding: Low steps were poorly detected, device-only travel produced more collisions in one pilot, and glove travel was slower than cane use.
No perfect-performance claim for Wearable navigation: the evidence register does not make “Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption” universal, consequence-free or flawless in A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane.
Scope remains Wearable navigation: A six-metre indoor training route has one doorway, one waist-high foam obstacle and no stairs or drop-offs. A wearable gives left, right, stop and obstacle cues; the learner keeps the usual cane. Recheck the comparator, support and “Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption” after any configuration change.
