Abstract

The primary challenge in optical see-through near-eye displays lies in providing correct optical focus cues. Established approaches such as varifocal or light field display typically sacrifice temporal or spatial resolution of the resulting 3D images. This paper explores a new direction to address the trade-off by combining a retinal projection display (RPD) with ocular wavefront sensing (OWS). Our core idea is to display a depth of field-simulated image on an RPD to produce visually consistent optical focus cues while maintaining the spatial and temporal resolution of the image. To obtain the current accommodation of the eye, we integrate OWS. We demonstrate that our proof-of-concept system successfully renders virtual contents with proper depth cues while covering the eye accommodation range from 28.5 cm (3.5 D) to infinity (0 D).


網膜投影型HMDに眼科臨床で用いる視力計測系を組み合わせることで、装着者の眼のピントを計測し、対応する焦点ボケを再現したAR画像を提示できるARグラスを開発しました。
本研究は、コースティクス波面計測系と呼ばれる光学系の歪みを計測する手法を網膜投影HMDと組み合わせることで、「装着者の視力を計測し、計測した視力を補正して映像を提示できるARグラス」への展望を示すものです。
ARグラスで乱視等の高次収差に基づく視力補綴を自動で行えるシステムを目指し、改良を進めます。
