材料设计是艺术家或设计师设置虚拟表面的外观属性以实现期望外观的过程。这个过程通常在虚拟合成环境中进行，然而，计算机视觉跟踪和交互式渲染的进步现在使得在增强现实（AR）中设计材料成为可能，而不是纯粹的虚拟合成环境。然而，AR环境中的设计如何影响用户行为尚不清楚。为了评估在真实的环境中工作如何影响材料设计过程，我们提出了一种新的材料设计界面，允许设计师与有形的对象进行交互，因为他们指定的外观属性。该设置使设计人员有机会在操纵对象时通过虚拟现实设置查看外观属性的实时渲染。我们的设置使用相机来捕捉设计师的物理环境，以在叠加在有形对象上的虚拟视图上创建微妙但逼真的反射效果。这些效果基于实际设计空间的物理照明条件。我们描述了一个用户的研究，比较我们的方法的功效，传统的三维虚拟合成材料设计系统。我们研究中的主观反馈和定量分析都表明，我们的设置提供的现场体验可以创造更高质量的材料特性，并支持交互和沉浸感。
Material design is the process by which artists or designers set the appearance properties of virtual surface to achieve a desired look. This process is often conducted in a virtual synthetic environment however, advances in computer vision tracking and interactive rendering now makes it possible to design materials in augmented reality (AR), rather than purely virtual synthetic, environments. However, how designing in an AR environment affects user behavior is unknown. To evaluate how work in a real environment influences the material design process, we propose a novel material design interface that allows designers to interact with a tangible object as they specify appearance properties. The setup gives designers the opportunity to view the real-time rendering of appearance properties through a virtual reality setup as they manipulate the object. Our setup uses a camera to capture the physical surroundings of the designer to create subtle but realistic reflection effects on the virtual view superimposed on the tangible object. The effects are based on the physical lighting conditions of the actual design space. We describe a user study that compares the efficacy of our method to that of a traditional 3D virtual synthetic material design system. Both subjective feedback and quantitative analysis from our study suggest that the in-situ experience provided by our setup allows the creation of higher quality material properties and supports the sense of interaction and immersion.
