The study "The Application of Technology Acceptance Model and Theory of Planned Behavior to Discuss the Behavioral Intention of Wii Sports Gaming Participation" used the technology acceptance model and theory of planned behavior with perceived playfulness to discuss the behavior intention of Wii Sports gaming participation. This includes the dimensions of attitude toward behavior, subjective norm, perceived behavior control, perceived ease of use, perceived of usefulness, perceived playfulness and behavior intention, as well as the relations of each path. The junior and senior high(vocational ) school students in Tanzi and Houli District were our research subjects, and a total of 386 valid questionnaires were collected. The SPSS12.0 version and LISREL8.52 package were used to compose the data file and for the statistical analysis. Through the verification of the research hypotheses, the conclusions were as follows: perceived of usefulness has no significant impact on attitude toward behavior; the impacts on perceived ease of use to the attitude toward behavior, perceived playfulness to attitude toward behavior, perceived ease of use to perceived of usefulness, perceived ease of use to the perceived playfulness, attitude toward behavior to behavior intention, subjective norm to behavior intention, while perceived behavioral control to behavior intention were significantly positive. In this study, the verification of integrating the application of technology acceptance model and the theory of planned behavior with the addition of perceived playfulness to discuss the behavioral intention of Wii Sports gaming participation results in a comparatively good performance. The contribution of this study can be used as a reference for future research and direction.
