In this research, I conducted "a persuasive game" where a worker convinces the character about the importance of the work and analyzed the increase in motivation levels of the worker. When the worker fails to persuade, the worker confirms the importance of the work, so the motivation for work will be improved. In this experiment, I prepared two types of systems : one with a character that accept any persuation(conventional system) and one that may or may not accept a persuation , incorporating the success or failure of a persuation based on its cntent (proposed system), compare and evaluate each went. As a result, it was shown that the system that incorporates the success or failure of persuasion tends to significantly improve the motivation before work, compared with the conventional system.
