Building on the usability study: Two explorations on how to better understand an interface

Abstract

In this paper, we describe two separate studies that improved our ability to understand our users' experience of our products at salesforce.com. The first study explored a methodology of combining expert and novice performance data to yield a measure of intuitiveness. The second study created a methodology that combines both verbal and nonverbal emotion scales to better understand the emotional effect our products have on our users. We present both these methods as expansions on the standard usability study and examples of ways to better understand your users within an industry environment. © 2009 Springer Berlin Heidelberg.
