增强现实（AR）是将计算机图形（CG）图像叠加到用户对真实的世界的视图上的技术。常用的AR显示设备是光学透视头戴式显示器（OST-HMD），其是透明的HMD，使得用户能够直接观察到真实世界，并将CG添加到其中。此类系统中的常见问题是用户眼睛的属性与用于生成CG的虚拟相机之间的不匹配。我们系统的目标是在渲染中准确地反映用户眼睛的状态。使用自动折射仪，我们测量用户的瞳孔大小和屈光状态，并将这些值输入实时光线跟踪器。生成的渲染准确地反映了用户在其真实的世界视图中感知到的景深（DoF）模糊效果。在我们的演示中，用户可以通过同时观察3D打印物体旁边的CG对应物来验证我们系统的准确性。我们相信，我们的技术是实现与真实的对象难以区分的增强的最有前途的方法。将其集成到消费者OST-HMD中将是将照片逼真的AR带给大众的关键一步。
Augmented Reality (AR) is a technology which superimposes computer graphics (CG) images onto a user’s view of the real world. A commonly used AR display device is an Optical See-Through Head-Mounted Display (OST-HMD), which is a transparent HMD, enabling users to observe the real-world directly, with CG added to it. A common problem in such systems is the mismatch between the properties of the user’s eyes and the virtual camera used to generate CG. The goal of our system, is to accurately reflect the state of the user’s eyes in our renderings. Using an Auto Refractometer, we measure the user’s pupil size and accommodative state and feed these values into a realtime raytracer. The resulting renderings accurately reflect the Depth-ofField (DoF) blur effect the user perceives in their view of the real world. In our demo, users can verify the accuracy of our system by simultaneously observing 3D-printed objects next to their CG counterparts. We believe that our technique is the most promising way for achieving augmentations that are indistinguishable from real objects. Integrating it into consumer OST-HMDs will be a crucial step for bringing photo realistic AR to the masses.
