Evidence Notes.
8 Findings Published
Evidence
Primary referent: signal wifi bad.
Evidence
Implied function: The icon must communicate Signal WIFI Bad in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon effectively communicates the intended functional meaning of 'Signal WIFI Bad' with a high confidence (0.95) and strong perceptual convergence (0.75), indicating good visual robustness across size, blur, and contrast variations.
Evidence
Visual metrics show the icon is simple, cohesive, and maintains readability and contrast stability at small sizes, supporting its use as a compact symbolic control in digital interfaces.
Evidence
Semantic and functional convergence scores (0.57 and 0.60 respectively) indicate the icon generally maps well to its intended meaning and function, but there is moderate risk of confusion with similar icons such as Wi-Fi signal strength or close/cancel icons, especially when labels or contextual cues are weak.
Evidence
Cultural convergence is low (0.32) with a referent recognition score of 0.41 and functional association score of 0.59, suggesting that while some users recognize the symbol, it is not strongly culturally saturated or universally recognized across diverse user groups.
Evidence
The icon requires a moderate learned convention load (0.39) and has a neurocognitive transfer risk of 0.48, indicating that some users may struggle to infer the intended meaning without additional support such as tooltips or labels.

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Include a visible text label or tooltip alongside the icon to reduce ambiguity and support users with varying familiarity and accessibility needs.
Action
Ensure the icon is placed in a consistent and contextually clear location within the interface to minimize confusion with similar icons or controls.
Action
Conduct representative user testing across diverse user groups to validate comprehension and identify potential misunderstandings before publication.
Action
Monitor user feedback and usage data post-deployment to assess real-world effectiveness and update the icon or supporting elements as needed.
Action
Consider augmenting the icon with additional visual cues or animations in critical contexts to reinforce the 'bad Wi-Fi signal' status where misinterpretation risk is high.
