[ CASE INTERPRETATION ]

How the report reads.

Needs intervention

0.64

0-1 scale; higher is clearer. Support.

The pictogram carries meaningful clarity risk. It applies to this pictogram, this meaning, and this public context.

[ Report trace ]

Evidence stays attached from input to support.

Context first. Score second. Support last.

Submitted context

Framework output for the Material Symbols Speed 0 2x icon in the rounded style.

Observed referent

Primary referent: speed 0 numeric 2x.

Estimate driver

Implied function: The icon must communicate Speed 0 2x in a digital interface..

Recommended support

Run representative user testing before publication.

[ Score scale ]

How to read the level.

Needs intervention

The label names screening risk for this context. It is not a certification or a measured comprehension rate.

0.80-1.00

Strong clarity

The pictogram communicates well in this context.

Use it, then keep testing with real users.

0.65-0.79

Usable with support

The pictogram works with labels or context.

Pair it with text and monitor interpretation.

0.50-0.64

Needs intervention

Current report

The pictogram carries meaningful clarity risk.

Improve the symbol before relying on it.

0.00-0.49

Not reliable

The pictogram does not communicate enough alone.

Replace it or add strong alternative support.

[ CONVERGENCE PROFILE ]

Where evidence agrees.

The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It shows agreement between signals, not universal validity.

Convergent meaning profile

The radar shows where meaning converges. It does not certify universal validity.

How strongly visual form survives size, blur, contrast, and detail loss.

Convergent meaning profile
Axis	Score	Description
Perceptual Convergence	0.75	How strongly visual form survives size, blur, contrast, and detail loss.
Semantic Convergence	0.59	How strongly extracted meaning converges on one interpretation.
Functional Convergence	0.57	How strongly the symbol maps to the intended function.
Cultural Convergence	0.46	How strongly recognition holds across cultural evidence and assumptions.
Temporal Convergence	0.47	How strongly meaning persists over time without semantic decay.
Neurocognitive Convergence	0.54	How strongly the symbol follows AAC pictogram reading: transparent referent, concrete action, low convention load, and support.
Context Independence	0.62	How strongly meaning survives without external labels or placement cues.
Collective Resonance	0.46	How strongly public evidence supports shared recognition and persistence.

Cultural axis

0.46

Recognition depends on cultural exposure and prior assumptions, so shared understanding is weaker than visual recognition alone suggests.

Temporal axis

0.47

Meaning weakens over time when the source object or function is less present in everyday use.

Evidence floor

0.42

Public evidence is thin or unavailable for display, so the cultural reading stays cautious.

[ Published findings ]

What the case evidence says.

7 findings

Findings summarize the public reading for this pictogram. They do not replace user testing.

Finding 01

Primary referent: speed 0 numeric 2x.

Finding 02

Implied function: The icon must communicate Speed 0 2x in a digital interface..

Finding 03

Metaphor type: functional.

Finding 04

Functional meaning: The icon must communicate Speed 0 2x in a digital interface..

Finding 05

PCS total: 0.64.

Finding 06

Weakest convergence axis: Cultural Convergence.

Finding 07

External evidence context (OpenAlex, 1995) links the case to symbol interpretation, meaning transfer, interface context; it does not replace user comprehension testing.

[ RECOMMENDED SUPPORT ]

What to test next.

Recommendation

Run representative user testing before publication.

Recommendation

Keep the text label visible until semantic transparency is proven.

Recommendation

Keep visible label support when scores sit below strong clarity.

Recommendation

Validate interpretation with representative users before high-risk release.
