情報機器使用時における高齢者の視行動と操作行動による戸惑い状態識別手法の一提案

抄録

The purpose of this research is to assist older persons confused in using information devices by giving appropriate guidance. First, we describe a model of cognition-action interaction in using information devices. Second, we report an experiment that investigated the relationship between behavior of users and their confused states. We found that the task completion times and vertical and horizontal scanpath lengths were found to be related to confused state. Third, we suggest a recognition method of the confused state. At last we report an experiment that investigated the effect of the recognition method and the classified confused state.
