Exploring and manipulating complex virtual objects is challenging due to limitations of conventional controllers and free-hand interaction techniques. We present the TanGi toolkit which enables novices to rapidly build physical proxy objects using Composable Shape Primitives. TanGi also provides Manipulators allowing users to build objects including movable parts, making them suitable for rich object exploration and manipulation in VR. With a set of different use cases and applications we show the capabilities of the TanGi toolkit, and evaluate its use. In a study with 16 participants, we demonstrate that novices can quickly build physical proxy objects using the Composable Shape Primitives, and explore how different levels of object embodiment affect virtual object exploration. In a second study with 12 participants we evaluate TanGi's Manipulators, and investigate the effectiveness of embodied interaction. Findings from this study show that TanGi's proxies outperform traditional controllers, and were generally favored by participants.

TanGi：虚拟现实中具体对象探索和操作的有形代理

由于传统控制器和徒手交互技术的限制，探索和操纵复杂的虚拟对象具有挑战性。我们介绍了 TanGi 工具包，它使新手能够使用可组合形状基元快速构建物理代理对象。TanGi 还提供了 Manipulators，允许用户构建包括可移动部件在内的对象，使其适用于 VR 中丰富的对象探索和操作。通过一组不同的用例和应用程序，我们展示了 TanGi 工具包的功能，并评估了它的使用。在一项有 16 名参与者的研究中，我们证明新手可以使用可组合形状基元快速构建物理代理对象，并探索不同级别的对象体现如何影响虚拟对象探索。在有 12 名参与者的第二项研究中，我们评估了 TanGi' ■ 操纵者，并调查具身交互的有效性。这项研究的结果表明，TanGi 的代理优于传统控制器，并且普遍受到参与者的青睐。
