Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express wearable navigation in a declared context without inheriting broader claims.

What the current evidence supports

Wearable navigation aids can add cues in controlled settings; they are adjuncts until real-world safety and reliability are demonstrated.

How to observe or measure it without overclaiming

Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption. This measures the declared configured system and cannot by itself establish broad transfer, unaided ability, safety or legitimacy.

Myth

A smart wearable guarantees independent navigation

Metric

Collision type, drop-off/head obstacle detection, speed, auditory masking, workload, failure recovery and user-chosen adoption

Boundary

Report person, device/model/interface, task, assistance, failure state and comparator; the metric is not proof of unaided general capability.

Negative and limiting findings

  • Low steps were poorly detected, device-only travel produced more collisions in one pilot, and glove travel was slower than cane use.
  • No cited evidence supports perfect, universal or consequence-free performance.

Claims this evidence cannot support

  • A smart wearable guarantees independent navigation
  • The tool or robot's output proves an unaided, universal or permanent human superpower
  • A successful laboratory task proves independent real-world or clinical capability

How to learn this Power now.

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.

  1. Get readyObtain orientation-and-mobility assessment and confirm the approved wearable, route, aid and spotter.
  2. Learn the method8 concrete steps teach the permitted method from start to finish.
  3. See right and wrong4 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseThe 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.
  5. Check progressConfigured 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.

Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. The method is Power-specific; its actionability follows this treatment.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a supervision or non-attempt boundary; cultural, community-rights or affected-person authority; a restricted safety or legitimacy boundary.

A Power-specific tutorial is available at /tutorials/pwr-206/. It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence.
