Table 5

Examples of calculating aesthetic value.

Scheme number	1	2
Number of gaze points	364	341
Variance of duration of gaze point	0.23	0.24
Average duration of gaze point (s)	6.49	6.53
Pureness (%)	1/(364/20/1) × 100% = 5.49%	1/(341/20/1) × 100% = 5.87%
Proportion (s)	1/0.23 = 4.35	1/0.24 = 4.17
Contrast (s)	364 × 0.23/20 = 3.64	341 × 0.24/20 = 3.56
C/T	3.64/6.49 = 0.56	3.56/6.53 = 0.54
