## 5 Conclusions
### Step 1 Analyses with the Control Variables as the Input according to Table 11
#### a.1.3 Summary
The input variables Y3 and Y6 again are excluded, meaning that the user's feeling of \"effective\" in the role-play operations as expressed by his/her answers to questions X3 and X4 in the following  
X3: by using the system, I need only a short time to get to know various puppet roles;  
X4: by using the system, I can remember the puppet roles' characteristics quickly  
is of _no use_ to help the user to take the actions described in the following two questions:  
Y3: after using the system, I can write puppetry scripts and perform by myself;  
Y6: I will recommend my friends and family to use the system to learn puppetry  
as expressed in the user's answers to the above two questions. Appendix A.2.3. About the Functions of the Variable Pair (X5 and X6) of the \"effective\" Indicator  
Similarly, based on the six values of \(\Delta\)R\({}^{2}\), namely, 0.11 **, 0.15 **, 0.14 **, 0.05, 0.15 **, 0.06 of C1 through C3 and (X5 and X6) of the indicator \"enjoyable\" for Y1 through Y6, respectively, it can be seen that inclusion of (X5 and X6) can increase 11%, 15%, 14%, and 15% of the variances of Y1, Y2, Y3, and Y5, respectively, with different degrees of significance. The input variables Y4 and Y6 are excluded, meaning that the user's feeling of \"enjoyable\" in the role-play operations as expressed by his/her answers to questions X5 and X6 in the following  
X5: it is interesting to use the system to learn puppet performances and narrations;  
X6: by using the system, I can feel the sense of being a professional puppeteer  
is _of no use_ to help the user to take the actions described in the following two questions:  
Y4: the role play conducted on the system is a good set of cultural learning materials;  
Y6: I will recommend my friends and family to use the system to learn puppetry  
as expressed in the user's answers to the above two questions. Appendix A.2.4. Summaries  
(B.4.1) By a detailed check of the above three results, it can be seen that Y1, Y2, and Y5 can be \"explained\" significantly, to different degrees though, by all the three variable pairs of (X1 and X2), (X3 and X4), and (X5 and X6), or equivalently, by all the six independent variables X1 through X6. Therefore, the following concluding remark can be drawn: the situations of the role-play process that the user feels while using the proposed system, as expressed by the answers to the six questions of X1 through X6, overall reflect the user's thoughts of:  
Y1: by experiencing the role play, I can learn a lot of the puppeteer's skills;  
Y2: by experiencing the role play, I can learn many puppet characters' narration skills; and  
Y5: after using the system, I can remember the puppet characteristics and operation skills as expressed in the user's answers to the above three questions. (B.4.2) On the contrary, Y3, Y4, and Y6 cannot be \"explained\" significantly by all the three variable pairs (X1 and X2), (X3 and X4), and (X5 and X6) in the above analyses. Specifically, the following facts can be drawn. (B.4.2.1) Y3 described in the following  
Y3: after using the system, I can write puppetry scripts and perform by myself;  
can only be \"explained\" significantly by (X5 and X6) of the indicator of \"enjoyable\" described in the following  
X5: it is interesting to use the system to learn puppet performances and narrations;  
X6: by using the system, I can feel the sense of being a professional puppeteer. (B.4.2.2) Y4 described in the following  
Y4: the role play conducted on the system is a good set of cultural learning materials;  
can be \"explained\" significantly only by (X1 and X2) and (X3 and X4) of the indicators of \"easy\" and \"effective\" described in the following  
X1: the system interface is easy to understand and simple to operate;  
X2: it is easy to understand the role classification by using the system;  
X3: by using the system, I need only a short time to get to know puppet roles;  
X4: by using the system, I can remember the puppet roles' characteristics quickly, but not significantly by (X5 and X6) as mentioned previously.
