| Outline of Final Research Achievements |
The purpose of this research is to extend the depth of field in head-mounted displays (HMDs) using the coded aperture technology. Specifically, a coded aperture was set in front of the eyeball using an optical see-through HMD, and a image was sharpened in advance by a point spread function corresponding to the opening shape and the depth of the gazing point was developed . In order to confirm the effectiveness of the developed method, we made a prototype system capable of viewing the presentation image at a fixation position with a fixed depth. In a small-scale subjective experiment, the aperture shape made of film was set in the optical see-through HMD, and a point light source was presented. It was confirmed that the aperture shape was visually recognized even when the subject gazed at the outside of the depth of field of the HMD.
