Augmented Reality 3D Design Space

Abstract

Conceptual design is an important early design stage for the product development process. 3D CAD systems are extensively used in product design but not in conceptual design. Augmented Reality (AR) merges real and virtual objects in a real environment. In this research, the main objective is to develop an AR 3D design space for generating design concepts during conceptual design. The developed system, named Augmented Reality Computer-Aided Design Environment (ARCADE), allows the user to create the function models and 3D models, and evaluate the functional behavior and ergonomics. An intuitive method based on building blocks and extrusion approaches for generating 3D model using bare hand interactions has been developed. The function model is represented by a Product Use Model (PUM). A Functional 3D model (F3DM) with a Function-Behavior-Structure modeling framework has been implemented to reason the functional behavior. A hand strain detection methodology is developed to evaluate the design?s ergonomics. Case studies and user studies have been conducted using ARCADE for conceptual design.
