ARCAD: Augmented Reality Computer Aided Design

Abstract

This thesis explores the potential for creation of three-dimensional, parametric computer aided design (CAD) models using augmented reality technology. The current standard – a flat screen – can only display two dimensions of information, which constrains the display of three-dimensional geometry as either perspective, parallel, or orthographic projection. Each projection type has trade-offs, resulting in distortion, inaccurate scale, or the need of multiple planar projections to capture three-dimensional space. Augmented reality technology overcomes the limitations of the flat screen – for the first time, holographic, truly three-dimensional display of geometry is possible and can be integrated into a real scene by using a head-mounted AR/Mixed Reality headset, affording a CAD display that imparts better understanding and accuracy during the entirety of the product development process. Using current devices and adapted practices, I developed a prototype mixed reality solid modeling environment to simulate the experience of using such a tool, and test how we might interact with it. This thesis documentation reflects the process of creating the interactive demonstration and reflects on the lessons and feedback gained from the students, enthusiasts, and industry professionals who engaged with it.
