Outline of Final Research Achievements

The purpose of this research is to realize a display method that solves both (1) the problem of Vergence Accommodation Conflict (VAC), and (2) the problem of image presentation delay in optical see-through HMDs. We researched a volumetric display principle that achieves an image update frequency of 1000 Hz by controlling the presentation depth position with a high-speed variable-focus lens and a high-speed strobe. A prototype system was developed, and it demonstrated its effectiveness through evaluation experiments.

Academic Significance and Societal Importance of the Research Achievements

本研究により,人間の眼の焦点調節に整合する高速な三次元ディスプレイを実現する手法が開発できた.この技術は従来技術に比べてより自然な三次元画像を人間に提示できるため,視聴者がより自然にかつストレスなく利用できるヘッドマウントディスプレイやARディスプレイを実現するための基礎技術として学術的・社会的意義を持つものである.
