# Exploring the Impact of Virtual Reality on Painting Appreciation
## 3 Results and Discussion
### Multiple Regression Analysis  
For the multiple regression analysis, the respondent's sex and 10 questionnaire items were used as the input variables, and preference was used as the response variable. A stepwise multiple regression analysis was used to establish a regression model of preference for the four presentation methods, and the following results were obtained:  
1. Original paintings: Preference = 2.23 + 0.41 (the work is attractive), adjusted R\({}^{2}\) = 0.36, \(p\) < 0.001
2. Albums: Preference = 0.20 +0.41 (I would like to hang this painting in my house) +0.22 (the work is original) +0.25 (mood = relaxed), adjusted R\({}^{2}\) = 0.53, \(p\) < 0.001
3. Desktop VR: Preference = 1.55 +0.39 (I would like to hang this painting in my house)

* Items with high correlations (0.69 < r < 0.99) are indicated with a light purple background, those with moderate correlations (0.39 < r < 0.7) with a light red background, and those with low correlations (r < 0.4) with a light blue background. The original description of “meaning of cloud” is “the artworks make me feel the form or meaning of cloud”; the original description of “title encouragement” is “the title intensifies my interest in the painting”; and the original description of “hang it in my house” is “1 would like to hang this painting in my house”.

4. HTC Vive:  
Preference = 1.82  
+0.39 (I would like to hang this painting in my house)  
+0.15 (mood = pleasure), adjusted R\({}^{2}\) = 0.40, \(p\) < 0.001  
The regression results indicate that when viewing the original painting, the preference was primarily affected by its attractiveness, whereas in the other three presentation methods, it was affected by the willingness of the participant to hang it at home. Thus, the preference for a painting is positively affected when it makes viewers feel that they want to hang it at home. Additionally, when paintings are presented through albums or desktop VR, viewers can discern their originality, which enhances their preference. Therefore, to promote preference, the presentation method of an HTC Vive must focus on the pleasure imparted by the viewing process.
