Extended Methods to Dynamically Estimate Emphasizing Points for Group Decision-making and their Evaluation

In previous work, we proposed and evaluated a method of dynamic estimation of emphasizing points (DEEP). The purpose of this study is to extend DEEP to estimate the emphasizing points of a group. A preliminary experiment investigated whether the interaction process would differ depending on the interaction style used, avoiding conflict or expressing opinions. We also proposed two extended methods corresponding to the different interaction processes. We then conducted an experiment to evaluate the methods using Embodied Conversational Agents. In conclusion, these proposed methods accurately estimate proposals and satisfy participants in the appropriate group.
