To easily compare information on the basis of vision of a user with a brain activity state of the user.SOLUTION: A brain activity recording system includes an information processing device, a brain activity measuring device connected to the information processing device, and an imaging device connected to the information processing device. In the brain activity recording system, the brain activity measuring device has a measuring section which is worn on a user and measures a predetermined brain activity state of the user, the imaging device has an imaging section which is worn on the user and photographs in a visual line direction of the user, and the information processing device has a control section which acquires a measurement value of the brain activity state of the user from the brain activity measuring device, acquires a user image obtained by photographing in the visual line direction of the user from the imaging device, estimates an attribute of an object to be visually recognized included in the user image photographed by the imaging device using an estimation model for estimating the attribute of the object to be visually recognized included in the image from the image, and outputs the measurement value of the brain activity state of the user and the attribute of the object to be visually recognized included in the estimated user image in association with each other.SELECTED DRAWING: Figure 5【課題】利用者の視覚に基づく情報と利用者の脳活動状態との比較を容易に行えるようにする。【解決手段】情報処理装置と、情報処理装置に接続される脳活動計測装置と、情報処理装置に接続される撮像装置とを含む脳活動記録システムであって、脳活動計測装置は、利用者に装着され、利用者の所定の脳活動状態を計測する計測部を有し、撮像装置は、利用者に装着され、利用者の視線方向を撮影する撮像部を有し、情報処理装置は、利用者の脳活動状態の計測値を脳活動計測装置から取得し、利用者の視線方向を撮影した利用者画像を撮像装置から取得し、画像から当該画像に含まれる視認対象の属性を推定する推定モデルを用いて、撮像装置で撮像された利用者画像に含まれる視認対象の属性を推定し、利用者の脳活動状態の計測値と推定された利用者画像に含まれる視認対象の属性とを対応付けて出力する制御部を有する、脳活動記録システムとする。【選択図】図５
