Evidence Notes.
8 Findings Published
Evidence
Primary referent: battery vert 020 numeric.
Evidence
Implied function: The icon must communicate Battery Vert 020 in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon effectively represents a battery at approximately 20% charge in a vertical orientation, aligning with its intended functional meaning as a digital interface status marker.
Evidence
Visual quality is strong with high perceptual convergence (0.79), indicating good resilience to size, blur, and contrast variations, and an overall visual score of 0.81.
Evidence
Semantic convergence (0.57) and functional convergence (0.60) are moderate, showing the icon generally conveys its intended meaning and function but with some ambiguity.
Evidence
Cultural convergence is low (0.32), reflecting limited public evidence and cultural recognition for this specific icon variant, which may affect universal comprehension.
Evidence
Temporal convergence (0.57) suggests the icon's meaning persists reasonably well over time without significant semantic decay.

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Conduct representative user testing across diverse user groups to validate comprehension and identify potential confusion, especially given the moderate semantic and functional convergence scores.
Action
Maintain visible text labels or tooltips alongside the icon until sufficient semantic transparency and cultural recognition are demonstrated through testing and usage data.
Action
Ensure clear placement and contextual cues in interfaces to reduce risk of confusion with neighboring icons or controls, particularly for users with varying platform conventions and accessibility needs.
Action
Consider supplementary training or onboarding materials to support users unfamiliar with this specific battery charge level icon variant.
Action
Monitor evolving cultural and temporal evidence to assess if the icon's recognition and meaning improve or degrade over time, adjusting design or usage accordingly.
