可调节的深度线索、宽广的视野和越来越高的分辨率都给近眼显示器的硬件设计带来了重大挑战。优化设计以克服其中一个挑战通常会导致对其他挑战的权衡。我们通过引入一种一体化解决方案来解决这个问题，即一种用于增强现实应用的新的宽视场、注视跟踪近眼显示器。我们解决方案的关键组成部分是为每只眼睛使用一个透明、变焦可变形膜镜来反射显示器。它们由气密腔控制，并改变有效焦度，以在由凝视跟踪器确定的目标深度平面处呈现虚拟图像。使用薄膜的好处包括宽视野（100 对角线）和快速深度切换（300 毫秒内从 20 厘米到无限远）。我们的主观实验验证了原型并展示了其对近眼透视显示器的潜在优势。
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.
