Quantification of concern for others to social skill evaluation

This paper addresses a quantification technique of cooperative characteristics on Concern For Others: CFO in a cooperative work by multiple operators. The cooperative works are generally required suitable cooperation to accomplish the task adequately. Although the “cooperation” is one of keywords for social psychological field, few study has been investigated for engineering application, that is, quantification of the cooperative characteristics is not focused on. Thus, most of researches on human-machine systems have been considered to assist a single operator. In that case, human intention concentrates upon only faced robot operation. Measured input command by the operator includes all of operator´s intention. However, in cooperative works, measured input probably contains the effect from other operators, that is CFO. A challenge of this study is to quantify the cooperative characteristics as the CFO in cooperative tasks. Then CFO utilizes to realize a novel assist system to enhance their cooperation. To obtain CFO in such tasks, the human input pattern during a solo work was learned by human model before the cooperative task. Then, the difference between measured input command in cooperative work and the predicted command in the human model is defined as the CFO. Finally, this paper addresses the correlation analysis between the CFO and cooperative task performance.
