在本文中，我们提出了AffordIt！，为虚拟对象的组成部分添加功能的工具。在3D场景重建和分割过程中，用户发现自己拥有完整的虚拟对象，但没有分配固有行为，迫使他们使用不熟悉的基于桌面的3D编辑工具。负担!提供了一个直观的解决方案，允许用户选择感兴趣的网格切割工具的区域，分配一个固有的行为，并查看他们的工作的动画预览。评估可用性和工作负荷的AffordIt！我们进行了一项探索性研究来收集反馈。在研究中，我们使用两个网格切割机形状来选择一个感兴趣的区域和两个移动行为，然后用户将其分配给一个常见的家庭物体。结果显示了高可用性和低工作负载评级，证明了AffordIt！作为一个有价值的3D创作工具。基于这些初始结果，我们还提出了未来工作的路线图，将在未来的迭代中改进该工具。
In this paper we present AffordIt!, a tool for adding affordances to the component parts of a virtual object. Following 3D scene reconstruction and segmentation procedures, users find themselves with complete virtual objects, but no intrinsic behaviors have been assigned, forcing them to use unfamiliar Desktop-based 3D editing tools. AffordIt! offers an intuitive solution that allows a user to select a region of interest for the mesh cutter tool, assign an intrinsic behavior and view an animation preview of their work. To evaluate the usability and workload of AffordIt! we ran an exploratory study to gather feedback. In the study we utilize two mesh cutter shapes that select a region of interest and two movement behaviors that a user then assigns to a common household object. The results show high usability with low workload ratings, demonstrating the feasibility of AffordIt! as a valuable 3D authoring tool. Based on these initial results we also present a road-map of future work that will improve the tool in future iterations.
