humanperceived

Humanperceived is a term used to describe attributes, judgments, or qualities as they are experienced by human observers, rather than as measured by objective physical quantities. It emphasizes the subjective aspect of perception.

In practice, humanperceived properties depend on context, the sensory modality involved, individual differences (age, sensory acuity, attention), and cognitive factors such as expectations and biases. Psychophysics studies these relationships by linking physical stimuli to reported perceptions.

Assessment methods include controlled experiments, sensory panels, and user studies. Measurements are often collected with surveys (Likert scales), forced-choice tasks, or difference tests. Results seek to predict how changes in stimuli will be perceived rather than simply how they exist physically.

Applications span product design and evaluation: visual displays optimized for perceived brightness rather than irradiance, audio codecs evaluated by perceived sound quality, and user interfaces shaped by perceived usability. In marketing, humanperceived attributes influence branding and user acceptance.

Limitations: high subjectivity, variability across populations, cultural differences, and susceptibility to biases. Difficult to replicate across laboratories; requires careful experimental design. The term itself is informal; scholarly literature often uses 'perceived' as a dependent measure.
