1 Introduction

Gamers have the pleasure to live vicariously through some digital avatar in a myriad of different environments ranging from a soldier in World War II, to a warlock in some enchanted land, or even a vigilante street racer in a dystopian world. Presently, players must use a hand-held controller to interface with these digital worlds. One of the many controls available to these gamers is the trigger. This document provides the basic operating principles and shows the design process for one possible version of a gaming controller trigger. Challenges in the design process are also documented.

Figure 1-1 summarizes the design flow presented in this document.
