Area of Science:

  • Architecture
  • Environmental Psychology
  • Human-Computer Interaction

Background:

  • Interior lighting design aims for user comfort and functionality.
  • Understanding generational preferences is crucial for inclusive design.
  • Previous research often overlooks age-specific responses to lighting environments.

Purpose of the Study:

  • To investigate generational differences in evaluating interior lighting.
  • To identify factors beyond visibility influencing lighting perception.
  • To inform the development of lighting designs accommodating diverse age groups.

Main Methods:

  • Utilized 15 computer-generated images of interior spaces with varying luminous environments.
  • Employed a Semantic Differential technique with 12 subjective scales (5-step).

  • Recruited participants from three distinct age groups: young, middle-aged, and elderly.

    • Main Results:

    • Significant differences were observed in how generations evaluated interior lighting.
    • Visibility alone did not fully explain the observed generational tendencies.
    • Personal experience emerged as a key factor correlating with evaluation and preference.

    Conclusions:

    • Generational background significantly influences the perception of interior lighting.
    • Interior lighting design should consider the role of personal experience alongside visual performance.
    • Future designs must integrate age-specific preferences for optimal user accommodation.
