The pictogram does not communicate enough alone.
Replace it or add strong alternative support.
[ CONVERGENCE PROFILE ]
The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It shows agreement between signals, not universal validity.

Weakest Axis
Neurocognitive Convergence
How strongly the symbol follows AAC pictogram reading: transparent referent, concrete action, low convention load, and support.
Strongest Axis
Perceptual Convergence
How strongly visual form survives size, blur, contrast, and detail loss.
| Axis | Score | Description |
|---|---|---|
| Perceptual Convergence | 0.75 | How strongly visual form survives size, blur, contrast, and detail loss. |
| Semantic Convergence | 0.32 | How strongly extracted meaning converges on one interpretation. |
| Functional Convergence | 0.49 | How strongly the symbol maps to the intended function. |
| Cultural Convergence | 0.37 | How strongly recognition holds across cultural evidence and assumptions. |
| Temporal Convergence | 0.58 | How strongly meaning persists over time without semantic decay. |
| Neurocognitive Convergence | 0.31 | How strongly the symbol follows AAC pictogram reading: transparent referent, concrete action, low convention load, and support. |
| Context Independence | 0.38 | How strongly meaning survives without external labels or placement cues. |
| Collective Resonance | 0.32 | How strongly public evidence supports shared recognition and persistence. |
Cultural axis
0.37
Recognition depends on cultural exposure and prior assumptions, so shared understanding is weaker than visual recognition alone suggests.
Convention load
1.00
The pictogram asks users to know a convention instead of inferring the action directly from the drawing.
Transfer risk
0.90
Seeing the object does not guarantee transfer to the intended communication task.
[ Published findings ]
8 findings
Findings summarize the public reading for this pictogram. They do not replace user testing.
Finding 01
Primary referent: 21 megapixel camera.
Finding 02
Implied function: The icon must communicate 21 Megapixel Camera in a digital interface..
Finding 03
Metaphor type: abstract.
Finding 04
Functional meaning: The icon must communicate 21 Megapixel Camera in a digital interface..
Finding 05
PCS total: 0.60.
Finding 06
The visible mark is a compact alphanumeric code; reading the characters does not prove transfer to the intended technical meaning.
Finding 07
Neighbor-code confusion needs explicit testing when adjacent codes can share the same visual family.
Finding 08
The sign behaves as a learned convention rather than a transparent pictogram.

[ RECOMMENDED SUPPORT ]
Recommendation
Keep a visible label for compact numeric codes unless tested users distinguish the code family reliably.
Recommendation
Run forced-choice testing against neighboring codes and require the exact intended state, not just character recognition.
Recommendation
Test object-to-action transfer with neurodivergent participants.
Recommendation
Validate whether users learn the convention or infer the action directly.
Recommendation
Run representative user testing before publication.
