我们提出了一种技术，允许视频透视式头盔显示器的用户在近距离工作，而不会因为今天大多数商用HMD中鼻侧立体声重叠的减少而典型地丧失立体声感知。我们的技术动态地选择广角头戴式相机获取的部分成像圆锥体，并将它们重新投影到较窄的视场显示。除了在启发式估计的工作距离处动态地保持对象的最大立体重叠之外，它还减少了适应-收敛冲突，代价是新引入的差异-收敛冲突。我们描述了我们系统的硬件(由商业组件组装而成)和软件实现，并报告了在两个不同的AR应用中使用该技术的经验。(外加彩板)。
We present a technique that allows users of video see-through head-mounted displays to work at close range without the typical loss of stereo perception due to reduced nasal side stereo overlap in most of today's commercial HMDs. Our technique dynamically selects parts of the imaging frustums acquired by wide-angle head-mounted cameras and re-projects them for the narrower field-of-view displays. In addition to dynamically maintaining maximum stereo overlap for objects at a heuristically estimated working distance, it also reduces the accommodation-vergence conflict, at the expense of a newly introduced disparity-vergence conflict. We describe the hardware (assembled from commercial components) and software implementation of our system and report on our experience while using this technique within two different AR applications.
