在桌面操作3D对象本身就存在问题。桌面缺乏第三自由度，因此需要新颖的解决方案来支持最简单的3D操作。我们的解决方案是TZee——一个被动的有形小部件，通过利用漫射照明（DI）多点触控桌面的照明特性，实现与3D对象的自然交互。TZee由堆叠的亚克力玻璃层组装而成，将桌面的红外光稍微延伸到表面以上，而无需额外的电源。有了TZee，用户可以直观地在所有三个维度上缩放、平移和旋转对象，还可以执行更复杂的手势，比如“切片”一个体积物体，这在现有的桌面交互方案中是不可能的。TZee是用经济实惠的材料建造的，一个桌面表面可以很容易地支持多个TZee。此外，由于TZee是透明的，因此有许多可能性可以通过反馈、有用的提示或其他视觉增强来增强交互。我们讨论了几个重要的设计注意事项，并通过几个应用程序演示了TZee的价值。
Manipulating 3D objects on a tabletop is inherently problematic. Tabletops lack a third degree of freedom and thus require novel solutions to support even the simplest 3D manipulations. Our solution is TZee - a passive tangible widget that enables natural interactions with 3D objects by exploiting the lighting properties of diffuse illumination (DI) multi-touch tabletops. TZee is assembled from stacked layers of acrylic glass to extend the tabletop's infrared light slightly above the surface without supplemental power. With TZee, users can intuitively scale, translate and rotate objects in all three dimensions, and also perform more sophisticated gestures, like "slicing" a volumetric object, that have not been possible with existing tabletop interaction schemes. TZee is built with affordable and accessible materials, and one tabletop surface can easily support multiple TZees. Moreover, since TZee is transparent, there are numerous possibilities to augment interactions with feedback, helpful hints, or other visual enhancements. We discuss several important design considerations and demonstrate the value of TZee with several applications.
