ABSTRACT

This chapter will provide you with the necessary information to introduce physiological measures into your player studies, and will point you to in-depth resources available for further study.

14.1.1 Overview of Our Research Along with several co-authors, I conducted a series of experiments to develop a new method for continuously modeling user emotional state in interactive play environments based on a user's physiological responses. The goal was to develop an evaluation methodology for games that: captures usability and playability through metrics relevant to ludic experience; accounts for user emotion; is objective and quantitative; and has a high evaluative bandwidth (continuous measurement). Our approach was to collect physiological data as a direct indication of user experience. We explored the following physiological measures: galvanic skin response (GSR), heart rate (HR), electromyography (EMG) of the face Gaw, forehead, cheek), and respiration.
