3D User Interfaces

Chapter 3. Human Factors Fundamentals

This chapter explores human factors issues that typically affect the design of a 3D UI. We focus on how users process information. Additionally, perception, cognition and physical ergonomics issues are explored, which will be reflected in the subsequent chapters on interaction technology and techniques.

3.1 Introduction

When a novel 3D interaction device or technique is being designed, it is important to consider the human factors that affect its usability and performance. While not always discussed or analyzed in much detail, human factors are an important cornerstone of a user-centered design process. The term “human factors” refers to the capabilities, characteristics, and limitations of the human user, ...
