Evidence Notes.
8 Findings Published
Evidence
Primary referent: nest thermostat sensor.
Evidence
Implied function: The icon must communicate Nest Thermostat Sensor in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon effectively represents the Nest Thermostat Sensor with a clear circular device shape, central dial, and pointer elements, supporting its intended functional meaning as a smart home temperature sensor control.
Evidence
Visual perceptual quality is strong, with high scores for visual complexity, cohesion, and robustness to size and blur, ensuring good recognition across platforms and display conditions.
Evidence
Semantic and functional convergence scores are moderate (around 0.5-0.57), indicating some ambiguity or potential confusion with similar thermostat or climate control icons, especially when labels or context are weak.
Evidence
Cultural recognition and collective resonance are low (around 0.3 and 0.24 respectively), reflecting limited widespread cultural familiarity or public evidence supporting shared recognition of this specific icon.
Evidence
The icon requires a moderate learned convention load (0.41) and has a notable neurocognitive transfer risk (0.51), suggesting that some users may struggle to infer the intended meaning without additional cues.
