Seamless Interaction and Visualization in Perspective Corrected Multi Display Environments

我们研究了在透视校正多显示环境(MDE)中使用便携式投影仪来扩展工作空间的方法。该系统使用用户和显示器之间的相对位置，以便以不变形的方式垂直于用户的视点显示内容。我们将便携式投影仪创建的图像作为一个新的、临时的和可移动的图像引入透视校正后的MDE中，为用户创造了一个更灵活的工作空间。在我们的研究中，我们结合了两种使用投影仪的方式(手持或头戴式)和两种在屏幕上移动光标的方式(使用鼠标或基于激光指向的策略)，提出了四种技术供用户尝试。此外，我们还进行了两个探索性的评估实验来评估我们的系统。

We study ways to use a portable projector to extend the workspace in a perspective corrected multi display environment (MDE). This system uses the relative position between the user and displays in order to show the content perpendicularly to the user's point of view in a deformation-free fashion. We introduce the image created by the portable projector as a new, temporary and movable image in the perspective corrected MDE, creating a more flexible workspace to the user. In our study, we combined two ways of using the projector (handheld or head-mounted) with two ways of moving the cursor on the screens (using a mouse or a laser-pointing based strategy), proposing four techniques to be tried by the users. Also, two exploratory evaluation experiments were performed in order to evaluate our system.
