| Outline of Final Research Achievements |
The purpose of this study is to establish a visual augmentation technique to support microscopic observation. First, we proposed and confirmed the effectiveness of a method for estimating the three-dimensional gazing position using eye tracking information obtained from an eye tracker on an Head Mounted Display presenting a stereo camera image. Then, we proposed a balloon type dielectric elastomer actuator (DEA) equipped with four electrodes, and constructed an optical system that can drive the three-dimensional position of a lens. We also demonstrated that the system can be used for tracking and focusing microscale objects. Finaly, we found that video presentation with dynamic focus control based on the depth of the gazing position may have a higher recognition rate of depth than static video presentation.

| Academic Significance and Societal Importance of the Research Achievements |
視線計測に基づいてリアルタイムにステレオカメラの映像の焦点を変更し，HMDを用いて提示する新しい視覚拡張を実現した点に意義がある．さらに，DEAを用いたレンズ駆動により，肉眼では直接捉えることのできないマイクロスケールの対象物について，インタラクティブな可視化ができた．これらを発展させることで，従来の顕微鏡による観察を効率化したり，新しいVirtual Reality体験を生み出すことができると考えられる．
