Conceptual Models Matter!

Implications to Human Performance, Usability, and Experience

Abstract

This chapter discusses why the conceptual model matters by examining “human performance” implications, on the one hand, and “usability and user experience” implications. Human performance refers to perceptual, cognitive, emotional, and physical processes and behaviors. Usability and user experience refer to the effectiveness, the efficiency, and the subjective experience associated with users interacting with an application in order to accomplish goals.
