对于光学透视头戴式显示器，显示器的焦距与真实的世界场景之间的失配无意中阻止用户同时聚焦于所呈现的虚拟内容和场景。已经表明，可以通过应用称为Sharp View的算法来改善具有已知焦距的图像的离焦模糊。然而，目前尚不清楚Sharp View是否也提高了显示器上呈现的文本的可读性和清晰度。在这项研究中，我们调查是否用户报告增加文本清晰度时，夏普视图应用于文本标签，以及如何显示的焦点需求，焦距到真实的世界的内容，和凝视条件影响的结果。我们的研究结果表明，在非固定观看，有一个显着的用户偏好夏普视图增强的文本字符串。
For optical see-through head-mounted displays, the mismatch between a display's focal length and the real world scene inadvertently prevents users from simultaneously focusing on the presented virtual content and the scene. It has been shown that it is possible to ameliorate the out-of-focus blur for images with a known focus distance, by applying an algorithm called Sharp View. However, it remains unclear if Sharp View also improves the readability and clarity of text rendered on the display. In this study, we investigate whether users reported increased text clarity when Sharp View was applied to a text label, and how the focal demand of the display, the focal distance to real world content, and gaze condition affect the result. Our results indicate that, in non-fixated viewing, there is a significant user preference for Sharp View-enhanced text strings.
