Spatial-audio augmentation

Spatial audio can turn a 3D scan into navigation cues. Early testing was only in six blindfolded sighted adults, so real value for blind and low-vision users remains an open, user-led question.

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 spatial-audio augmentation in a declared context without inheriting broader claims.

What the current evidence supports

A prototype can sonify a reconstructed environment and reduced obstacle contacts in six blindfolded sighted adults, but value for blind/low-vision users, dependable mobility and durable learning remain unestablished.

How to observe or measure it without overclaiming

Predeclare user vision/hearing, route, obstacles, moving hazards, sensor field, mapping and latency; measure collisions/near misses, path error, time, workload, audio masking, device failure, aid use and user-valued function.

Myth

See the world through sonar

Metric

Route completion, obstacle/near-miss rate, localization error, workload and fallback use in intended users

Boundary

A sighted-blindfolded prototype study cannot establish sight, safe street mobility or replacement of established aids.

Negative and limiting findings

  • The feasibility study tested no blind/low-vision user; participants were slower when assisted, and no evidence establishes street navigation, superiority to established aids, audio-masking tolerance or safe device failure.

Claims this evidence cannot support

  • Sonar vision
  • Replace a cane or guide dog
  • See with sound automatically
  • Safe navigation through any environment

How to learn this Power now.

Learner plus orientation-and-mobility professional produce a versioned Map v3 record showing cue-localisation errors, contacts or near misses, workload, cane use plus a stationary fallback after audio loss.

  1. Get readyGive the provider the exact task, hearing/vision/mobility history, current aids, sensory tolerances and preferred communication.
  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. PractiseQualified provider sets block length plus spacing. Record one short block per Map v3 configuration; repeat another day only after comfort plus device-off response pass. Any new device, cue mapping, volume, room or mobility aid requires a fresh cane-only baseline.
  5. Check progressRecord cue-localisation error, wrong-side response, contact, near miss, time, cane use, workload, speech masking, symptoms plus fallback success for cane-only versus Map v3 blocks.

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.
