我们提出了一种新的显示隐喻，通过引入自由形式、环境感知的显示表示和一组匹配的交互方案，扩展了协作环境中传统的桌面投影。为此，我们将为传统的矩形布局设计的个性化小部件或普通计算机应用程序映射到空间效率高的气泡中，这些气泡的扭曲是通过基于潜在的物理方法执行的。通过一组基于激光笔跟踪的交互操作符，这些自由形状的显示器可以使用焦点和上下文可视化技术进行转换和弹性变形。我们还以交互的方式为气泡的直观实例化、克隆、剪切和粘贴、删除和分组提供操作，并且我们允许用户绘制注释和使用投影键盘输入文本。此外，显示器的可选环境感知自适应能力是通过对投影几何形状进行难以察觉的实时扫描来实现的。然后，在刚体模拟中计算了非最优表面部件气泡的碰撞响应。投影曲面性质的提取与系统的主要应用并行进行。我们的方法完全基于现成的低成本硬件，包括dlp投影仪和火线摄像机。
We present a novel display metaphor which extends traditional tabletop projections in collaborative environments by introducing freeform, environment-aware display representations and a matching set of interaction schemes. For that purpose, we map personalized widgets or ordinary computer applications that have been designed for a conventional, rectangular layout into space-efficient bubbles whose warping is performed with a potential-based physics approach. With a set of interaction operators based on laser pointer tracking, these freeform displays can be transformed and elastically deformed using focus and context visualization techniques. We also provide operations for intuitive instantiation of bubbles, cloning, cut & pasting, deletion and grouping in an interactive way, and we allow for user-drawn annotations and text entry using a projected keyboard. Additionally, an optional environment-aware adaptivity of the displays is achieved by imperceptible, realtime scanning of the projection geometry. Subsequently, collision-responses of the bubbles with non-optimal surface parts are computed in a rigid body simulation. The extraction of the projection surface properties runs concurrently with the main application of the system. Our approach is entirely based on off the-shelf, low-cost hardware including DLP-projectors and FireWire cameras.
