### Summary of Research Finding Results of This Study  
After the expert interview and the questionnaire survey, in addition to the explanation of the phenomena shown by the resulting data (i.e., Tables 11-13), the statistical significances of these data are more interesting, and some concluding remarks can be drawn as described in the following.  
1. _Watching the videos of experts' puppet shows has positive effects on increasing the understanding of puppet rolesThe content about the classification of traditional puppet roles shown in the expert puppet performers' demonstration videos displayed on the background screen in the role-play process is helpful for the users to understand the characteristics and differences of the six types of puppet roles, namely, [PERSON], Dan, Jing, Mo, Chou, and Za. Through watching such videos, the users can have a preliminary understanding of the various characteristics of traditional puppet roles. The analyses of the questionnaire survey results suggest that watching such videos of the experts' puppet shows has positive effects on increasing the understanding of puppet roles.  
_The actions conducted during the role-play on the system can become a good set of materials for learning traditional puppetry--_  
With the help of AV devices and interactive displays as well as the users' in-person role-play operations, the proposed system can provide vivid experiences of the puppet show, different from watching static displays such as those in museums. The questionnaire survey results show that the actions of learning puppet operation skills, practicing show-dependent narration skills, as well as considering puppet operations as interesting all throughout the proposed system were accepted by the users with high degrees of recognition. This fact indicates that these recognized actions on the system can \"become a good set of materials for learning the traditional puppetry\".  
_The system design meets the requirements of the 3E indicators--_  
In this study, the 3E indicators [44] were adopted for the designs of the human-computer interface and the questions of the questionnaire survey for statistical evaluation of the system operations. The two-stage hierarchical regression analysis results show that the role-play operations offered by the proposed system meet the requirements of the three indicators, namely, easy interfacing operation, effective investigation and assessment, and enjoyable performance steps.  
_Encouragement of the users to conduct script writing, self-performance, and recommendation of the system to others was yet not achieved via the proposed system--_  
However, the two action items of \"carrying out script writing and conducting self-performance of puppetry\" (specified by question Y4 in the questionnaire) and \"recommending it to friends and family to use the system to learn puppetry\" (specified by question Y6) do not satisfy the significant standards of hierarchical regression analysis, indicating that it is not easy to achieve the goal of promoting the glove puppetry just by short-time operation experiences obtained on the proposed system, leaving this as an issue for further research.
