ストレス・QoL推定
人の内面的な状態,例えばストレスやQoL(Quality of Life)を推定するという研究を行っています.働き方改革のもと,労働者のストレスチェックは社会課題となっており,スマートフォンやウェアブルで簡単に自分の状態を知れるようにするというのがゴールとなります.これまで,QoLの調査には,WHOQOL-BREFなどの紙の質問票が用いられてきたのですが,この結果とセンサデータの相関会計を分析したところ,機械学習によってある程度認識できることを明らかにしました.今後は,実際の会社での実験や他の質問票(ワークエンゲージメントなど)への対応を行っていきます.

Apple Watchのアクティビティリマインダのように,情報機器が人間に対して,働きかけ,次の行動を変化させるということが現実のものになろうとしています.行動を変えられるこうした情報機器を,生活習慣病予防のDigital Medicineと呼ぶこともあり,今後,社会に広まっていくと考えられます.我々は,通りかかる人に能動的に話しかけるデジタルサイネージを開発し,日々の対話の中で行動変容を喚起することができるかについて実証的研究を行っています.
