在虚拟现实（VR）设备中，眼框是用于表征VR设备的性能的重要因素。传统的眼动测量方法非常耗时，因为必须在多个位置进行测量以确定三维范围。在本文中，提出了一种新的测量方法，需要调查的光线从虚像的特定位置延伸的轨迹。当漫射平面位于用户眼睛位置附近时，这些光线在漫射平面上形成可识别的亮度分布图案。允许用户看到虚拟图像的位置的瞳孔的位置可以从这些分布的重叠中导出。此外，通过改变漫射屏的位置可以确定眼框的三维范围。此外，所提出的方法允许同时测量左眼和右眼的眼框。因此，所提出的方法可以用于相对快速地确定眼框的三维范围。
In a virtual reality (VR) device, the eyebox is an importance factor that is used to characterize the performance of the VR device. The conventional eyebox measurement method is quite time consuming as measurements must be performed at multiple positions to determine the three‐dimensional range. In this paper, a new measurement method is proposed that entails investigating the trajectories of the light rays extending from a specific position of the virtual image. These light rays form an identifiable brightness distribution pattern on the diffusing plane when this plane is located near the eye position of user. The positions of the pupil that allow the user to see the positions of the virtual image can be derived from the overlap of these distributions. Additionally, the three‐dimensional range of the eyebox can be determined by changing the position of the diffusing screen. Furthermore, the proposed method allows simultaneous measurement of the eyebox of the left and right eyes. Thus, the proposed method can be used to relatively quickly determine the three‐dimensional range of the eyebox.
