## Summary

Framework output for the Noun Project public-domain toilet pictogram in a public signage context.

## Interpretation

Visible referent: toilet fixture pictogram. Intended message: Communicate toilet or restroom access in public signage. The report separates observed asset evidence, submitted context, and public evidence signals.

## Diagnostic

Assessing whether a toilet fixture pictogram transfers as public restroom signage

This reviewed case history estimates whether the toilet fixture pictogram supports public restroom access as an AAC-baseline signage symbol. Scores are screening estimates and do not replace user testing.

## Findings

- Primary referent: toilet fixture pictogram.
- Implied function: Communicate toilet or restroom access in public signage..
- Metaphor type: functional.
- The toilet pictogram shows strong perceptual convergence (0.86), indicating excellent visual clarity and resilience to size, blur, and contrast loss, supporting recognition under varied viewing conditions.
- Semantic convergence is moderate (0.66), reflecting a generally clear but not fully unambiguous interpretation of the symbol as restroom access, consistent with the functional metaphor of a toilet fixture.
- Functional convergence (0.65) aligns with the intended use to communicate toilet or restroom access, but some risk remains that users may not immediately infer location or access without additional context.
- Cultural convergence (0.65) is moderate, supported by cultural assumptions and evidence that toilet fixture imagery is widely recognized for restroom signage, though some cultural variation and semantic obsolescence exist.
- Temporal convergence (0.63) shows reasonable persistence of meaning over time, with some evidence of semantic decay and generational divide, but overall stable recognition.

## Recommendations

- Conduct targeted user testing with neurodivergent and AAC users to assess and improve object-to-action transfer and reduce neurocognitive transfer risk.
- Maintain visible text labels or supporting cues alongside the pictogram until semantic transparency and neurocognitive comprehension are empirically validated.
- Consider design refinements to enhance semantic clarity and reduce potential confusion with plumbing fixtures, improving functional and semantic convergence.
- Monitor cultural and temporal trends to ensure the symbol remains relevant and comprehensible across diverse user groups and over time.
- Test object-to-action transfer with neurodivergent participants.
