solutions. Throughout the book, we attempt to more explicitly discuss visual interface design concepts, methods and issues, as well as issues related to a number of platforms beyond the desktop. Terminology and examples in the book have been updated to reflect the current state of the art in the industry, and the text as a whole has been thoroughly edited to improve clarity and readability. We hope that readers will find these additions and changes provide a fresh look at the topics at hand.
intermediacy, and the expert must not find his vertical runs obstructed by aids for trepidatious or conservative intermediates. In many cases, a well-balanced user interface takes the same approach. It doesn’t cater to the beginner or to the expert, but rather devotes the bulk of its efforts to satisfying the perpetual intermediate. At the same time, it provides mechanisms so that both of its smaller constituencies can be effective. Most users in this middle state would like to learn more about
sciences. Any attempt to reduce human behavior to statistics is likely to overlook important nuances, which can make an enormous difference to the design of products. Quantitative research can only answer questions about “how much” or “how many” along a few reductive axes. Qualitative research can tell you about what, how, and why in rich detail that is reflective of the actual complexities of real human situations. Social scientists have long realized that human behaviors are too complex and
needs and behaviors vary? What ranges of behavior and types of environments need to be explored? 08_084113 ch04.qxp 4/3/07 6:02 PM Page 61 Chapter 4: Understanding Users: Qualitative Research Roles in business and consumer domains For business products, roles — common sets of tasks and information needs related to distinct classes of users — provide an important initial organizing principle. For example, for an office phone system, we might find these rough roles: People who make and
these variables will represent a continuous range of behavior (for instance, from a computer novice to a computer expert), and a few will represent multiple discrete choices (for example, uses a digital camera versus uses a film camera). Mapping the interviewee to a precise point in the range isn’t as critical as identifying the placement of interviewees in relationship to each other. In other words, it doesn’t matter if an interviewee falls at precisely 45% or 50% on the scale. There’s often no
