InfoDesign
The current (September) edition of the InfoDesign newsletter, edited by Peter J. Bogaards, contains a rich assortment of user experience related articles. I selected some here:

User Experience: Towards a unified view (pdf)
Proceedings of the 2nd COST294-MAUSE International Open Workshop (October 2006, Oslo Norway) – “The concept of usability has been evolving, along with the emerging IT landscape and the ever-blurring boundary of the field of HCI. Specifically, the so-called user experience (UX) movement is gaining gound.”

The Art of the Conceptual Prototype [Blink Interactive]
“Conceptual prototypes are often very interesting projects because the ideas are leading edge. But they also present some unique challenges compared to more traditional projects where we are designing for actual implementation.”

XcD
“The scope of human-computer interaction design has widened to include concerns with fun, emotion, beauty, aesthetics and values. There is an increasing emphasis on holistic approaches to user experience and what is now called experience design. A number of frameworks and theoretical approaches to experience design have been developed and a range of methods and techniques have also been proposed. This website is part of the work carried out on the EPSRC grant Theory and Method for Experience Centred Design. This site links to our own work and that of others on theory and method for experience centred design or XcD as we seem to have started calling it.”

Design for the Dream Economy [uiGarden.net]
“After the eras of the Commodity Economy, the Manufacturing Economy, the Service Economy and the Information Economy, we have now entered the era of the Dream Economy.The key to success in the Dream Economy is an in-depth and holistic understanding of people. It’s not only about meeting people’’s practical needs, but also about meeting their aspirations and providing a positive emotional experience.”

Multi-Touch Systems That I Have Known and Loved [Bill Buxton]
“Since the announcement of the iPhone, an especially large number of people have asked me about multi-touch. The reason is largely because they know that I have been involved in the topic for a number of years. The problem is, I can’t take the time to give a detailed reply to each question. So I have done the next best thing (I hope). That is, start compiling my would-be answer in this document. The assumption is that ultimately it is less work to give one reasonable answer than many unsatisfactory ones.”

Card Sorting: Mistakes Made and Lessons Learned [UXmatters]
“Card sorting is a simple and effective method with which most of us are familiar. There are already some excellent resources on how to run a card sort and why you should do card sorting. This article, on the other hand, is a frank discussion of the lessons I’ve learned from running numerous card sorts over the years. By sharing these lessons learned along the way, I hope to enable others to dodge similar potholes when they venture down the card sorting path.”

Conducting Successful Interviews With Project Stakeholders [UXmatters]
“A simple, semi-structured, one-on-one interview can provide a very rich source of insights. Interviews work very well for gaining insights from both internal and external stakeholders, as well as from actual users of a system under consideration. Though, in this column, I’ll focus on stakeholder interviews rather than user interviews. (And I’ll come back to that word, insights, a little later on, because it’s important.)”

A Map-Based Approach to a Content Inventory [Boxes and Arrows]
“After giving it some thought, I find that the thing I like most about the map is that it is pure, stripped down navigation. Harry Beck decided that including streets, districts and other geographical information on his underground maps was distracting and added little value. All you need to know is how to get from A to B. I suspect that the same may be true in information spaces.”

Social Networks And Group Formation [Boxes and Arrows]
“Humans suffer from information overload; there’s much more information on any given subject than a person is able to access. As a result, people are forced to depend upon each other for knowledge. Know-who information rather than know-what, know-how or know-why information has become most crucial. It involves knowing who has the needed information and being able to reach that person.”

The Tagging Growth Curve [tagsonomy]
“The apparently irregular growth and spread of tagging is simply example of the real nature of how innovations spread. Professional analysts and other meaning makers tend to draw smooth graphs to depict these things. But in reality, natural systems (and the tagging / technology landscape is a legitimate ecosystem) are noisy, cyclical, chaotic, complex, fuzzy, non-linear, and unpredictable. They only appear to follow smooth curves at a high level of abstraction, or a low level of resolution.”

Looking Back on Data-Driven Design Research Personas [Todd Zaki Warfel]
“The primary goal of the tutorial was to show people how to work data into developing personas and how they can be used for more than just design.”
