The learner completes six global-to-local scans, reports correct names and structural cues separately, and records which cue repairs each error on an unfamiliar-object retest.

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 haptic object recognition in a declared context without inheriting broader claims.

What the current evidence supports

Humans can recognise and retain rich information about objects through active touch, but performance depends on object, scale, experience and access.

How to observe or measure it without overclaiming

Declare object familiarity, scale, exploration time, hand/motor access, vision condition and same- versus crossmodal test; report errors by object class.

Myth

Know any object by touch

Metric

Novel-object identification and delayed crossmodal recognition by scale and access

Boundary

Memory for handled familiar objects does not establish universal material, hazard or navigation recognition.

Negative and limiting findings

  • Age and reduced object scale lowered haptic shape discrimination.
  • A group comparison cannot establish that blindness biologically enhances touch.

Claims this evidence cannot support

  • Blind people have automatically superior touch
  • Identify any object instantly
  • Haptic memory replaces every other sense
  • One object test measures tactile intelligence

How to learn this Power now.

The learner completes six global-to-local scans, reports correct names and structural cues separately, and records which cue repairs each error on an unfamiliar-object retest.

  1. Get readyInspect every object visually and remove sharp edges, loose parts, residue, allergens and objects that can spill or switch on.
  2. Learn the method6 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. PractisePractise six to eight objects on two sessions per week for two weeks. Replace at least half the set each session and keep the same scan order. Stop before grip fatigue; do not shorten time until accuracy and complete cue descriptions are stable.
  5. Check progressCount correct names out of six and separately count trials with an outer-form description, two linked parts and a confidence rating compared with correctness.

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.
