User-Centered BCI Videogame Design

Abstract

This chapter aims to offer a user-centered methodological framework to guide the design and evaluation of Brain-Computer Interface videogames. This framework is based on the contributions of ergonomics to ensure these games are well suited for their users (i.e., players). It provides methods, criteria, and metrics to complete the different phases required by a human-centered design process. This aims to understand the context of use, specify the user needs, and evaluate the solutions in order to define design choices. Several ergonomic methods (e.g., interviews, longitudinal studies, user-based testing), objective metrics (e.g., task success, number of errors), and subjective metrics (e.g., mark assigned to an item) are suggested to define and measure the usefulness, usability, acceptability, hedonic qualities, appealingness, emotions related to user experience, immersion, and presence to be respected. The benefits and contributions of the user-centered framework for the ergonomic design of these Brain-Computer Interface videogames are discussed.
