Not reliable

The pictogram does not communicate enough alone.

Replace it or add strong alternative support.

Evidence Notes.

8 Findings Published

Evidence

Primary referent: call merge.

Evidence

Implied function: The icon must communicate Call Merge in a digital interface..

Evidence

Metaphor type: functional.

Evidence

The icon effectively represents the 'call merge' function with a strong perceptual convergence score (0.79), indicating good visual clarity and resilience across sizes and display conditions.

Evidence

Semantic convergence (0.5) and functional convergence (0.57) are moderate, showing that while the icon generally communicates the intended action, some ambiguity remains.

Evidence

Cultural convergence is low (0.3), reflecting limited widespread recognition and cultural saturation of the symbol, which may affect comprehension across diverse user groups.

Evidence

Temporal convergence (0.56) and neurocognitive convergence (0.56) suggest moderate persistence of meaning over time and reasonable alignment with pictogram reading principles, but some users may require learned conventions to interpret the icon correctly.

Evidence

Context independence is moderate (0.55), indicating the icon can convey meaning without external labels or placement cues to some extent, but risk of confusion remains especially when used alone.

[ RECOMMENDED NEXT ACTIONS ]

What Improves This Pictogram.

Action

Conduct representative user testing across diverse user groups to validate comprehension and identify potential confusion with neighboring interface actions.

Action

Include visible text labels or tooltips alongside the icon, especially in contexts where semantic transparency is not yet proven, to reduce misinterpretation risk.

Action

Ensure consistent placement and contextual cues in the interface to support correct interpretation and reduce confusion with similar icons such as call split or call transfer.

Action

Consider accessibility needs by providing alternative text descriptions and ensuring sufficient contrast and size for users with visual impairments.

Action

Monitor cultural and temporal trends in icon comprehension to update or supplement the icon as needed to maintain clarity and relevance over time.
