In order to gain more insight into the perceived differences between S3D designs, the participants provided ratings for the clarity and pleasantness in a scale from 1 (lowest score) to 5 (highest score). The results are presented in Figure 3, showing that the design with Frames (F) was rated as the best in both qualities. To ascertain if there were significant differences between the users’ subjective opinions of clarity and pleasantness, repeated measures ANOVA tests were conducted. Despite of the seemingly superior rating for both clarity and pleasantness, no statistically significant differences were indicated (F(3, 24) = 2.1, p = .1 and F(3, 24) = 2.3, p = .1 respectively).
