Evidence Notes.
8 Findings Published
Evidence
Primary referent: alarm off.
Evidence
Implied function: The icon must communicate Alarm Off in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon's primary referent is 'alarm off,' clearly representing an alarm bell with a diagonal slash indicating the alarm is disabled or muted.
Evidence
Visual metrics indicate strong perceptual clarity with high scores in visual complexity, cohesion, and robustness to scale and blur, supporting good recognition at small sizes.
Evidence
Semantic and functional convergence scores are moderate (0.55 and 0.60 respectively), showing the icon generally communicates the intended 'alarm off' function but with some risk of confusion with similar icons such as 'alarm on' or 'notification bell' especially when labels or context are weak.
Evidence
Cultural convergence is low (0.32) with a referent recognition score of 0.41 and functional association score of 0.59, indicating limited cultural saturation and some reliance on learned conventions rather than universal recognition.
Evidence
Temporal convergence (0.57) suggests the meaning persists over time but with some semantic obsolescence (score 0.12) and temporal decay (0.18), reflecting that the symbol may be less intuitive for some users or over time.

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Conduct representative user testing across diverse user groups to validate comprehension and reduce confusion with similar icons.
Action
Maintain visible text labels or tooltips alongside the icon until semantic transparency and user familiarity are confirmed through testing.
Action
Ensure consistent placement and contextual cues in the interface to minimize misinterpretation, especially given the icon's moderate semantic and cultural convergence.
Action
Consider alternative or supplementary iconography if user testing reveals significant confusion or low recognition, particularly for accessibility purposes.
Action
Monitor evolving cultural and technological contexts to address potential semantic obsolescence and maintain icon clarity over time.
