Outline of Final Research Achievements

This study discusses the feasibility to estimate the concentration level of Japanese document workers using computer. Based on the previous findings that dual-task scenarios increase reaction time, we hypothesized that the Kana-Kanji conversion confirmation time (KKCCT) would increase due to the decrease in cognitive resources allocated to the document task, i.e. the level of concentration on the task at hand. To examine this hypothesis, we conducted a set of experiments in which sixteen participants copied Kana text by typing and concurrently converted it into Kanji under three conditions: Normal, Dual-task, and Mental-fatigue. The results suggested the feasibility that KKCCT increased when participants were less concentrated on the task due to subtask or mental fatigue. These findings imply the potential utility of using confirmation time as a measure of concentration level in Japanese document workers.

Academic Significance and Societal Importance of the Research Achievements

日本語のテキスト入力で普遍的に発生するかな漢字変換の確認時間と集中度の関連性は，将来的には実時間での集中度の推定につながるものと期待される．その社会応用には，作業者へのフォードバックやリモートワーカ同士での遠隔共有などが想定され，集中の支援や作業阻害の回避などによる知的生産性の向上を期待することができる．
