To improve accuracy in estimating attentiveness of a subject to various situations.SOLUTION: An electronic device 10 provided herein comprises an image capturing unit 11, a line-of-sight detection unit 12, and a control unit 14. The image capturing unit 11 captures and generates an image corresponding to a scene. The line-of-sight detection unit detects a line of sight of a subject with respect to the scene. The control unit 14 estimates the arousal level of the subject according to the image and the line-of-sight. The control unit 14 functions as an estimation unit. The estimation unit is constituted by machine-learned learning data of a relationship between a learning image and biological information on the line of sight of a learning subject with respect to the learning image and the arousal level of the learning subject.SELECTED DRAWING: Figure 1
【課題】多様な状況に対して対象者の注意力の推定精度を向上する。【解決手段】電子機器10は撮像部11と視線検知部12と制御部14とを有する。撮像部11は撮像により光景に対応する画像を生成する。視線検知部は光景に対する対象者の視線を検知する。制御部14は画像および視線に基づいて対象者の覚醒度を推定する。制御部14は推定部として機能する。推定部を学習用画像と当該学習用画像に対する学習長対象者の視線と当該学習用対象者の覚醒度に関する生体情報との関係が機械学習された学習データによって構築している。【選択図】図1
