Evidence Notes.
8 Findings Published
Evidence
Primary referent: car lock.
Evidence
Implied function: The icon must communicate Car Lock in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon's primary referent is a car lock, effectively representing vehicle security in digital interfaces.
Evidence
Visual form shows strong perceptual convergence (0.75), indicating good resilience to size, blur, and contrast variations.
Evidence
Semantic convergence (0.55) and functional convergence (0.6) are moderate, showing the icon generally conveys intended meaning and function but with some ambiguity.
Evidence
Cultural convergence is low (0.32), reflecting limited shared recognition and cultural saturation, which may cause comprehension variability across user groups.
Evidence
Temporal convergence (0.57) and neurocognitive convergence (0.56) suggest moderate persistence of meaning over time and reasonable alignment with pictogram reading principles.

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Conduct representative user testing across diverse user groups to validate comprehension and reduce confusion risks.
Action
Maintain visible text labels or tooltips alongside the icon until semantic transparency and cultural recognition improve.
Action
Enhance contextual cues in the interface to support correct interpretation, especially where the icon appears alone.
Action
Consider design refinements to increase silhouette fidelity and bounding box balance to improve visual clarity and recognition.
Action
Monitor cultural and temporal trends to detect any emerging obsolescence or generational divides in symbol comprehension.
