Evidence Notes.

8 Findings Published

Evidence

Primary referent: battery 20 numeric.

Evidence

Implied function: The icon must communicate Battery 20 in a digital interface..

Evidence

Metaphor type: functional.

Evidence

The icon's primary referent is the numeric representation of 'Battery 20', intended to communicate a battery charge level of approximately 20% in digital interfaces.

Evidence

Visual metrics indicate strong perceptual clarity with an overall visual score of 0.83, demonstrating good resilience to size, blur, and contrast variations.

Evidence

Semantic and functional convergence scores (0.63 and 0.67 respectively) show moderate clarity in conveying the intended meaning and function, but there is some risk of confusion with similar battery icons or other interface elements when context or labels are weak.

Evidence

Cultural convergence is moderate (0.56), supported by evidence from multiple research sources, though cultural saturation and evidence reliability scores suggest limited widespread research and some uncertainty.

Evidence

Temporal convergence (0.65) indicates reasonable persistence of meaning over time, with low semantic obsolescence (0.18) and low generational divide (0.15), suggesting stable recognition across age groups.

[ RECOMMENDED NEXT ACTIONS ]

What Improves This Pictogram.

Action

Conduct user testing specifically including neurodivergent participants to assess and improve object-to-action transfer and semantic transparency.

Action

Maintain visible text labels or tooltips alongside the icon in interfaces until sufficient evidence confirms users reliably interpret the icon without additional cues.

Action

Ensure icon placement and surrounding context clearly differentiate this icon from similar battery or interface symbols to reduce confusion risk.

Action

Consider iterative design improvements to enhance neurocognitive convergence, such as simplifying visual elements or increasing iconic transparency.

Action

Monitor evolving cultural and semantic evidence to detect any future semantic obsolescence or generational comprehension gaps.
