Table 3 Descriptive statistical analysis of each metric and their interpretations in the context of obstructive scenery
Metrics | Statistical Values | Interpretation | Implication for Design |
|---|---|---|---|
S_ECI | Mean = 0.916; Mdn = 0.968; 95% CI [0.860, 0.972] | Near maximum value of 1 | Ensures clear distinction of foreground outlines |
P_ECI | Mean = 0.649; Mdn = 0.576; 95% CI [0.451, 0.847] | Moderate range | Enables smooth depth transitions |
S_ADI | Mean = 0.864; Mdn = 0.985; 95% CI [0.765, 0.963] | Near maximum value of 1 | Strong visual guidance capability |
S_VFR | Mean = 0.39; Mdn = 0.359; 95% CI [0.302, 0.478] | Lower proportion | Moderate visual field occupation |
P_LN | Mean = 169.65; Mdn = 170; 95% CI [140.335, 198.965] | Above median of 128 | Closer positioning to the observer |
P_LV | Mean = 99.25; Mdn = 93.5; 95% CI [71.436, 127.064] | Relatively low values | Controlled depth extension |
Foreground T_ESI, T_ISI, T_ER | T_ISI = 0.025, 95% CI [0.009, 0.041]; T_ER = 2.05, 95% CI [1.560, 2.540]; T_ESI = 1.324, 95% CI [1.148, 1.500] | Lower values | Simplified textural patterns |
Middle and background T_ESI, T_ISI, T_ER | T_ISI = 0.481, 95% CI [0.368, 0.594]; T_ER = 6.25, 95% CI [5.129, 7.371]; T_ESI = 3.543, 95% CI [2.729, 4.357] | Higher values | Rich, complex textures |
