While researchers have considered tracking annotations on 2D physical surfaces, this project explores the issues for tracking annotations on 3D physical models to accommodate complex objects, track annotations in difficult conditions, and consider the compatibility with 3D printing technology. During the early stages of design, designers do not want to work within the complexity of a CAD system and prefer to work with physical models. Linking the edits and annotations on a physical model with a digital model allows the benefits of digital models to be available while working with physical models. The intellectual merit of this project is in evaluating the feasibility for tracking annotations on physical objects in comparison to fully digital interfaces for early stage design. A new passive optical tracking method will be developed to accommodate complex objects, tracking in difficult conditions, and 3D printing technology. This project will impact the way in which designers use rapid prototyping by integrating edits on physical models with digital models. These techniques will be used in teaching architecture students and influence the expanding role of physical models in design.

虽然研究人员已经考虑了在二维物理表面上跟踪注释，但本项目探索了在3D物理模型上跟踪注释以适应复杂对象的问题，在困难条件下跟踪注释的问题，以及考虑与3D打印技术的兼容性。在设计的早期阶段，设计师不希望在复杂的CAD系统中工作，而更喜欢使用物理模型。将物理模型上的编辑和注释与数字模型连接起来，可以在使用物理模型时使用数字模型的优点。这个项目的智力价值在于评估了在物理对象上跟踪注释的可行性，并与早期设计的全数字接口进行了比较。将开发一种新的被动光学跟踪方法，以适应复杂物体，在困难条件下跟踪和3D打印技术。这个项目将影响设计师使用快速原型设计的方式，通过整合物理模型和数字模型的编辑。这些技术将用于建筑学生的教学，并影响物理模型在设计中的扩展作用。
