#### 4.2.2 Eye-Movement Metric Extraction and Data Analysis of Nine Samples  
The hotspot map in Figure 9 and the eye-movement experimental data in Table 5 clearly show that Sample 8 stands out and is more favored by users due to the large red area of the hot spot map, the longest first gaze duration, the largest number of looks, and

Analysis of Experimental Results of Subjective Evaluation of Semantics and Satisfaction in Ceramic Teapot Modeling  
As shown in Table 6, before data analysis, reliability analysis was conducted on the semantic and satisfaction questionnaire data, and the Cronbach \(\alpha\) coefficients were 0.711 and 0.782, respectively, indicating good reliability.  
Validity analysis was performed on the semantic and satisfaction questionnaire data, and the KMO values were 0.647 and 0.724, respectively, indicating that the data were suitable for extracting information.  
Finally, the data were tested for normal distribution. The absolute value of kurtosis of the satisfaction questionnaire and semantic words for the questionnaire is less than 10, and the absolute value of skewness is less than 3, indicating that although the data are not absolutely normal, they can basically be accepted as having a normal distribution.  
Therefore, the experimental data passed the reliability, validity, and normal distribution tests, meaning that the \(t\)-test and variance analysis could be carried out to lay the foundation for subsequent accurate analysis.
