Chapter 9. System Control
On a desktop computer, we input text and commands using 2D UI elements such as pull-down menus, pop-up menus, or toolbars on an everyday basis. These elements are examples of system control techniques—they enable us to send commands to an application, change a mode, or modify a parameter. While we often take the design of such techniques in 2D UIs for granted, system control and symbolic input are not trivial in 3D applications. Simply adapting 2D desktop-based widgets is not the always the best solution. In this chapter, we discuss and compare various system control and symbolic input solutions for 3D UIs.
9.1 Introduction
The issuing of commands is a critical way to access any computer system’s functionality. For ...
