Abstract: オフィスや学習の場などにおける,執務者・学習者の知的作業時の集中度を客観的・定量的に評価できる技術を開発した.認知モデルに基づく集中度評価指標であり,評価時の習熟の影響を受けない特徴がある.また評価に要する計測・解析ツールも開発した.これにより,執務空間・学習空間の室内空間設計・評価や執務・学習支援器具の設計・評価が可能となる.またこれを用いて,オフィス向けに省エネルギーかつ集中度を向上させる照明システムを開発し,従来照明と比較し集中度を平均約5 %ポイント,向上率平均で10.0 %向上させる効果が確認された(N=21, p<.01).
The authors have proposed concentration time ratio as a new index to evaluate intellectual productivity, which has been difficult to quantitatively evaluate. It uses the concept of concentrating on a target task. In addition, a measurement tool has been developed based on the index. This intellectual concentration index can be used for designing and evaluating the indoor environment of offices and educational buildings. In addition, a new illumination system to improve workers' concentration has been developed. An experiment to evaluate intellectual productivity was conducted by employing Concentration Time Ratio (CTR). The results showed that the average CTR under the new illumination system was 5 percentage points higher than that under normal ambient lighting, and the average progress rate of CTR was 10.0 % (N=21, p<.01).
