| dc.description.abstract | 現今的虛擬實境 (virtual reality, VR) 頭戴顯示器以人類雙眼的視差來產生立體感，但是長時間穿戴該類虛擬實境裝置，會造成使用者的不適。我們在此論文中提出一個光場顯示器的設計，以減輕存在於大多虛擬實境裝置中的視覺輻輳調節衝突 (vergence- accommodation conflict)，建構出光場來提供更符合人類的視覺體驗。我們設計的重點在於光場顯示器的目鏡部分，該目鏡主要為重建一個更為密集濃縮的光場。光場顯示器中，目鏡的光學設計也同時可以減少近軸和離軸光線的像差，並增加整體顯示器的可視角度(field of view)。我們使用人眼的光學模型來驗證投射出來的光場是否正確，且能夠讓人感覺出深度的資訊，透過眼睛模型對焦在不同的距離，觀察視網膜上的影像，確認光場顯示器的效果，模擬實驗的結果也吻合人類的立體感知，並顯示出壓縮後的光場有足夠的細節資訊。 | zh_TW |
| dc.description.abstract | A head-mounted display (HMD) using stereoscopic images to create 3D sens¬ation may cause users to feel nauseous after using it for a while. The visual discomfort results from the inconsistency between the eye vergence and the eye accommodation. In this paper, we propose a novel light field display to alleviate the vergence-accommodation conflict existing in most stereoscopy-based HMD. The key to our near-eye display is an eyepiece that creates a condensed reproduction of the light field for display. This is achieved by minimizing the aberrations of on-axial and off-axial light rays and maximizing the field of view of the display. In addition, we use a human eye model to verify if the displayed light field leads to the desired depth perception. It involves observing the change of images on the retinal plane of the eye model as the eye focuses at different distances. The result matches human 3D perception and shows that the condensed light field contains sufficient details. | en |
