本文介绍了Limpid Desk，它通过在基于投影的混合现实环境中使文档堆栈的上层透明来支持物理桌面上的文档搜索。用户可以在视觉上访问下层文档，而无需物理地移除上层文档。这是通过投影图像将下层文档的覆盖纹理叠加在上层文档上来实现的。本文介绍了一种生成投影图像的方法，使物理文档透明。此外，针对系统的输入界面，提出了一种基于热图像处理的触摸传感方法。用户在物理文档上触摸的区域可以在没有任何用户佩戴或手持设备的情况下被检测到。该界面允许用户通过简单的触摸手势来选择要使其透明的堆栈。该系统实现了三种文档检索支持技术。用户研究进行，结果表明所提出的技术的有效性。
This paper presents Limpid Desk that supports document search on a physical desktop by making the upper layer of a document stack transparent in a projection-based mixed reality environment. A user can visually access a lower-layer document without physically removing the upper documents. This is accomplished by superimposition of cover textures of lower-layer documents on the upper documents by projected imagery. This paper introduces a method of generating projection images that make physical documents transparent. Furthermore, a touch sensing method based on thermal image processing is proposed for the system’s input interface. Areas touched by a user on physical documents can be detected without any user-worn or handheld devices. This interface allows a user to select a stack to be made transparent by a simple touch gesture. Three document search support techniques are realized using the system. User studies are conducted, and the results show the effectiveness of the proposed techniques.
