Extended Methods to Dynamically Estimate Emphasizing Points for Group Decision Making and the Evaluation


The purpose of this study is to extend a method of dynamic estimation of emphasizing points (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. The difference is caused by confidence in their opinions and their commitment to the decision making. 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. We could also observe that the participants carefully looked to their partner for their reaction in "avoiding conflict" group and that the participants concentrated on execution of the task in "expressing opinions" group.
