SP3X : a six-degree of freedom device for natural model creation

Abstract

This thesis presents a novel input device, called SP3X, for the creation of digital models in a semi-immersive environment. The goal of SP3X is to enable novice users to construct geometrically complex three-dimensional objects without extensive training or difficulty. SP3X extends the ideas of mixed reality and partial physical instantiation while building on the foundation of tangible interfaces. The design of the device reflects attention to human physiologic capabilities in manual precision, binocular vision, and reach. The design also considers cost and manufacturability. This thesis presents prior and contributing research from industry, biology, and interfaces in academia. A study investigates the usability of the device and finds that it is functional and easily learned, and identifies several areas for improvement. Finally, a Future Work section is provided to guide researchers pursuing this or similar interfaces. The SP3X project is a result of extensive collaboration with Mahoro Anabuki, a visiting scientist from Canon Development Americas, and could not have been completed without his software or his insight.
