Depth perception

Stereopsis can sometimes be recovered in selected adults, but depth perception is larger than binocular disparity.

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 depth perception in a declared context without inheriting broader claims.

What the current evidence supports

Some adults with abnormal binocular vision have recovered measurable stereopsis through intensive supervised perceptual learning; general recovery and daily-life transfer remain unproven.

How to observe or measure it without overclaiming

Report stereoacuity/disparity threshold and task, plus monocular cues and functional configuration; stereoacuity cannot diagnose or summarise all depth perception.

Myth

Unlock perfect 3D vision

Metric

Stereoacuity plus an unfamiliar functional depth task

Boundary

Stereo improvement does not establish every form of depth perception or remove need for correction and adaptations.

Negative and limiting findings

  • A paediatric randomised comparison did not show a between-treatment stereoacuity advantage.
  • Evidence does not erase legitimate monocular and assistive depth strategies.

Claims this evidence cannot support

  • Unlock 3D vision for everyone
  • Depth perception is one stereo score
  • Patching yourself retrains both eyes
  • No stereopsis means no usable depth

How to learn this Power now.

The learner classifies near/far relations in two novel image sets and correctly identifies the dominant pictorial cue and cue-conflict errors.

  1. Get readyUse images only; no stairs, catching, pouring or real distance judgement is tested.
  2. Learn the method8 concrete steps teach the permitted method from start to finish.
  3. See right and wrong6 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseUse one 10–15-image set once or twice weekly. Progress from single-cue to cue-conflict images, then novel scenes; clinical binocular treatment stays with eye professionals.
  5. Check progressRecord correct near/far relation, correct cue identification, cue conflicts, confidence, image setup and symptoms. Count whether cue-removal predictions correctly anticipate unchanged, weaker or reversed judgments.

Authority boundary: Titan teaches a concrete low-stakes method step by step while keeping evidence and transfer claims bounded. 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; a restricted safety or legitimacy boundary.

A Power-specific tutorial is available at /tutorials/pwr-069/. 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. Its self guided mode remains controlling.
