Accommodative depth cues, a wide field of view, and ever-higher resolutions all present major hardware design challenges for near-eye displays. Optimizing a design to overcome one of these challenges typically leads to a trade-off in the others. We tackle this problem by introducing an all-in-one solution - a new wide field of view, gaze-tracked near-eye display for augmented reality applications. The key component of our solution is the use of a single see-through, varifocal deformable membrane mirror for each eye reflecting a display. They are controlled by airtight cavities and change the effective focal power to present a virtual image at a target depth plane which is determined by the gaze tracker. The benefits of using the membranes include wide field of view (100° diagonal) and fast depth switching (from 20 cm to infinity within 300 ms). Our subjective experiment verifies the prototype and demonstrates its potential benefits for near-eye see-through displays.
适调深度提示、宽视场和不断提高的分辨率都对近眼显示器的硬件设计提出了重大挑战。为了克服其中一个挑战而优化设计，通常会导致在其他方面做出权衡。我们通过引入一种整体解决方案来解决这个问题 - 一种用于增强现实应用的新型宽视场、视线追踪近眼显示器。我们解决方案的关键组成部分是为每只眼睛使用单个透视、可变形的膜镜来反射显示器。它们由密封腔控制，并改变有效焦距，以在由视线追踪器确定的目标深度平面上呈现虚拟图像。使用膜的好处包括宽视场（100°对角线）和快速深度切换（在 300 毫秒内从 20 厘米切换到无限远）。我们的主观实验验证了原型，并展示了其在近眼透视显示器中的潜在优势。
