| 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.
