Outline of Research at the Start

本研究では,情報機器や情報ネットワークを使用しているユーザの客観的・連続的・無意識的に得られる脳波や脈波などの生体信号から,そのユーザの生理心理的体感品質を推定し,その変量に連動して情報ネットワークのパラメータを制御する『生体信号連動型ネットワーキング(Physiological Networking)』を提案する.これは,Soiciety5.0の計画で提唱されている「人間中心社会」における「必要なサービスを必要なときに必要なだけ提供する」機能へ貢献する.

Outline of Final Research Achievements

The purpose of this study is to derive a basic design guideline for physiological signal-based networking, in which a user's experience of network performance is continuously estimated from the user's physiological signals and the network is controlled in conjunction with the estimated results. We have validated several methods for estimating changes in the viewer's experience in response to changes in video quality, assuming changes in network traffic, from the viewer's EEG, blood volume pulse wave, and eye tracking data. As the results, we found that estimation accuracy was higher for the dataset that included physiological signals than for the dataset that did not include physiological signals. The coefficients of determination were found to be more than 0.8 for the datasets that included the properties of video and physiological signals.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は,ネットワークの状況やアプリケーションの応答,そして,それらへのユーザの反応や体感が逐次変化する循環の中でコンピュータやネットワークを自動的に制御する技術のための基礎的データになると考える.そして,Soiciety5.0の計画で提唱されている「人間中心社会」における「必要なサービスを必要なときに必要なだけ提供する」機能へ貢献すると考える.
