- Abstract
- This study is realized in the frame of a work aiming at evaluating the potential of several presentation modes whose images displayed on 2D, 3D and HDR monitors for studying the perceived visual appearance of daylit spaces. The paper discusses two metrological qualities (sensitivity and validity) of a questionnaire developed in this context. This questionnaire is composed of rating scales, multiple choice questions, and questions based on blank sketches. A first group of forty-three subjects visited actual rooms and responded to the questionnaire. A second group of forty-two participants responded to the same questionnaire without visiting the actual rooms but only on the basis of blank sketches. Results show that multiple choice questions are complementary to rating scales. The comparison of perceptions experienced by the participants having visited the actual rooms to responses given by the control group shows that luminous stimuli influence the way the participants rated the rooms. At last, perceptions experienced by the participants visiting the rooms are in accordance with the objective analysis of the rooms’ luminous conditions realized on the basis of luminance and illuminance measurements.
