论文摘要
在诸如计算机辅助设计（CAD）之类的域中建模3D对象是耗时的，并带有一条陡峭的学习曲线来掌握设计过程以及工具复杂性。为了简化建模过程，我们设计并实施了一个原型系统，该系统利用虚拟现实（VR）手势识别的优势，并结合了基于语音的界面的表现力，用于3D建模的任务。此外，我们使用VR环境中3D模型的建设性实体几何形状（CSG）树表示，让用户从头开始操纵对象，从而对基本基本形状如何连接有直觉的了解。该系统使用标准的空气3D对象操纵技术，并添加一组语音命令来帮助减轻当前手势识别技术的缺陷。进行了用户研究以评估所提出的原型。混合输入范式的结合表明，朝着更易于使用CAD建模的一步是有希望的一步。
Modeling 3D objects in domains like Computer Aided Design (CAD) is time-consuming and comes with a steep learning curve needed to master the design process as well as tool complexities. In order to simplify the modeling process, we designed and implemented a prototypical system that leverages the strengths of Virtual Reality (VR) hand gesture recognition in combination with the expressiveness of a voice-based interface for the task of 3D modeling. Furthermore, we use the Constructive Solid Geometry (CSG) tree representation for 3D models within the VR environment to let the user manipulate objects from the ground up, giving an intuitive understanding of how the underlying basic shapes connect. The system uses standard mid-air 3D object manipulation techniques and adds a set of voice commands to help mitigate the deficiencies of current hand gesture recognition techniques. A user study was conducted to evaluate the proposed prototype. The combination of our hybrid input paradigm shows to be a promising step towards easier to use CAD modeling.
