## 5 Conclusions
### Step 1 Analyses with the Control Variables as the Input according to Table 11
#### a.1.3 Summary  
It is noted that the contents of the three questions C1 through C3 are about _the basic altitude of the user toward the traditional puppetry_ after experiencing the role-play operation on the proposed system, with C1 about the fondness of puppet shows, C2 about the understanding of puppet roles, and C3 about the admiring of puppet skills. It is also noted that the six questions Y1 through Y6 are about the cognition, learning, promotion, and inheritance of the traditional puppetry with Y1 about the learning of puppet skills, Y2 about the learning of narration skills, Y3 about script writing and self-performance, Y4 about role-plays for use as cultural materials, Y5 about the cognition of puppet characteristics and operations, and finally Y6 about the recommendation of the experience to other people. As an overall summary of all the above analyses, it can be said that the user's altitude expressed in the users' answers to questions C1 through C3 is _related positively and significantly_ to the resulting changes of the user's notions of cognition, learning, promotion, and inheritance about the traditional puppetry expressed in the answers to questions Y1 through Y6. And this concluding remark shows partially the usefulness of the proposed system for sustaining the traditional puppetry. Step 2 Analyses with the Control Variables and the Three Independent Variable Pairs According to Table 12  
Step 2 analyses with C1 through C3 as the control variables and each of the three independent variable pairs (X1 and X2), (X3 and X4), and (X5 and X6) as the input have been conducted for each of the six dependent variables Y1 through Y6, yielding 18 cases of hierarchical regressions whose results are shown integrally in Table 12.  
It is noted that the questions of the six independent variables X1 through X6 were designed _to reflect the situations of the role-play process that the user feels_ while using the proposed system, and the questions of the three variable pairs (X1 and X2), (X3 and X4), and (X5 and X6) were designed respectively according to the 3E indicators of \"easy\", \"effective\", and \"enjoyable\" mentioned previously. Accordingly, the following facts can be drawn. About the Functions of the Variable Pair (X1 and X2) of the Indicator \"easy\"  
Based on the six values of \(\Delta\)R\({}^{2}\), namely, 0.18 ***, 0.14 **, 0.03, 0.08 *, 0.09 *, 0.07 of the three control variables C1 through C3 and the variable pair (X1 and X2) of the indicator \"easy\" for Y1 through Y6, respectively, it can be seen that inclusion of (X1 and X2) can increase 18%, 14%, 8%, and 9% of the variances of the four dependent variables Y1, Y2, Y4, and Y5, respectively, with different degrees of significance. The input variables Y3 and Y6 are excluded (whose \(\Delta\)R\({}^{2}\) are with no superscript of asterisks), meaning that the user's feeling of \"easiness\" in the role-play operations as expressed in his/her answers to the questions X1 and X2 shown 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  
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 two questions. About the Functions of the Variable Pair (X3 and X4) of the Indicator \"effective\"  
Similarly, based on the six values of \(\Delta\)R\({}^{2}\), namely, 0.10 *, 0.10 *, 0.04, 0.12 **, 0.10 **, and 0.04 of C1 through C3 and (X3 and X4) of the indicator \"effective\" for Y1 through Y6, respectively, it can be seen that inclusion of (X3 and X4) can increase 10%, 10%, 12%, and 10% of the variances of Y1, Y2, Y4, and Y5, respectively, with different degrees of significance.
