#### 5.2.2 Eye Movement Experimental Data  
The experimental samples are depicted in Figures 7 and 9, featuring six distinct layout forms, each accompanied by two stimulus images: an interface with transparent abstract rectangles and a real interface. The presentation format is as follows: initially, interfaces with transparent abstract rectangles are displayed, followed by the corresponding real interfaces. The six groups of layout interfaces are presented randomly.  
During the experiment, subjects are tasked with performing an image search task, wherein they must swiftly locate and accurately click on a navigation map icon while the real interface is playing. The presentation time for the real interface images is limited to 9000 milliseconds. If participants find the target before 9000 milliseconds, they can freely

Table 1: Aesthetic evaluation data. Calculated from the aesthetic measures of the interface layout in Figure 8 (in terms of symmetry, density, simplicity, order, and dominance).  
Figure 9: A\({}^{\prime\prime}\)–F\({}^{\prime\prime}\) represent sample interfaces with transparent abstract rectangles, respectively. Interface samples with transparent abstract rectangles. Combine the real interface from Figure 7 with the abstract rectangular interface from Figure 8 and reduce the transparency to facilitate participants’ connection with the real interface.

The experimental measurement data of fixation duration, fixation count, mean pupil diameter, gaze shift frequency and gaze time percentage were obtained using ErgoLAB software. Due to one participant wearing contact lenses, the eye-tracking device was unable to perform precise calibration, resulting in significant data deviation. Consequently, this set of experimental data was excluded. Ultimately, the data results from 37 participants were compiled, including 6 interface experts and 31 non-professionals. The statistical results are presented in Table 2. Additionally, an analysis of variance (ANOVA) and tests were conducted on five eye movement indicators. The results showed fixation duration (F = 3.126, \(p\) < 0.05), fixation count (F = 9.506, \(p\) < 0.05), mean pupil diameter (F = 20.089, \(p\) < 0.05), gaze shift frequency (F = 4.178, \(p\) < 0.05), and gaze time percentage (F = 5.506, \(p\) < 0.05). Therefore, the layout of interface elements has a significant impact on eye-tracking metrics.  
Figure 10: Experimental process and tasks. First, the interface with transparent abstract rectangles is displayed, followed by the corresponding real interface, until all six layout interfaces have been shown. When the real interface is presented, participants are required to complete an icon search task, which involves quickly finding and accurately clicking on the navigation map icon. Once the icon is clicked, the screen will automatically switch to the next image. The maximum presentation time for the real interface is 9000 ms.
