立体显示器向两只眼睛呈现不同的图像，从而产生令人信服的三维（3D）感觉。它们被开发用于许多应用，包括电影、电视、虚拟原型和医学成像。然而，立体显示引起知觉扭曲、性能下降和视觉疲劳。出现这些问题是因为某些呈现的深度线索（如透视和双眼视差）指定了预期的3D场景，而焦点线索（如模糊和调节）指定了显示本身的固定距离。我们已经开发出一种立体显示器，可以解决这些问题。它由一个与显示器同步的快速可切换镜头组成，这样焦点提示几乎是正确的。该系统在基础视觉研究和显示应用方面都有很大的潜力。
Stereoscopic displays present different images to the two eyes and thereby create a compelling three-dimensional (3D) sensation. They are being developed for numerous applications including cinema, television, virtual prototyping, and medical imaging. However, stereoscopic displays cause perceptual distortions, performance decrements, and visual fatigue. These problems occur because some of the presented depth cues (i.e., perspective and binocular disparity) specify the intended 3D scene while focus cues (blur and accommodation) specify the fixed distance of the display itself. We have developed a stereoscopic display that circumvents these problems. It consists of a fast switchable lens synchronized to the display such that focus cues are nearly correct. The system has great potential for both basic vision research and display applications.
