Wiimote interface for cutting and folding 3D digital model in architectural design

Architecture is a complex subject which can be seen as a synthetic organism. In order to create architecture, designer needs to visualize the design by using 3D model. Although there are many 3D programs at the present, the input interface is still mouse and keyboard which limit designer to work and sit in front of the screen. In addition, it is not intuitive to manipulate 3D object by 2D input interface. As the input device receives only 2 degrees of freedom, users require additional steps to operate their task. This might be the causes which make 3D model in digital difficult and take a lot of time. Therefore the design is frequently done by sketching in a paper or making a physical model. Then designers transform it into 3D digital model. This research tries to solve this problem by proposing intuitive interface which employs Wiimote to control and modify 3D object. The input device is able to send 6 DOF data so users easily manipulate 3D object only by moving or rotating input device. In conclusion, this report supposes that this interface will provide easier and faster method for designing in the conceptual stage of design by rotating and cutting 3D object.建筑学是一门复杂的学科，可被视作一种复合有机体。为开展建筑创作，设计师需通过三维（3D）模型可视化设计方案。尽管当前已有多款三维建模软件，但其主流输入界面仍为鼠标与键盘，这不仅限制了设计师的工作模式，使其必须久坐于屏幕前开展工作，且通过二维（2D）输入界面操控三维物体的操作逻辑并不直观。由于这类输入设备仅支持2个自由度，用户完成指定任务往往需要额外步骤，这也使得三维数字模型的创建过程繁琐且耗时极多。因此，设计师常先在纸上手绘草图或制作实体模型，再将其转化为三维数字模型。本研究旨在解决上述问题，提出一种基于Wiimote的直观交互界面，用于操控与修改三维物体。该输入设备可输出六自由度（6 DOF）数据，用户仅需移动或旋转该设备即可轻松操控三维物体。综上，本研究认为该交互界面能够为设计概念阶段的三维物体旋转与裁剪操作提供更便捷高效的解决方案。
