Structure and Style in Use Cases for User Interface Design

“Various styles for writing use cases are presented with examples and discussions of their relative advantages and disadvantages, particularly their consequences for user interface design and software usability. Essential use cases, a variant employed within usage-centered design, are contrasted with conventional use cases and scenarios. For the most efficient support of user interface design and particularly for large, complex projects, a highly-structured form of use case has evolved. New narrative elements and relationships among use cases are introduced. These include means for expressing partial or flexible ordering of interaction, relationships with business rules, as well as a clarification of the often misunderstood concept of extension that recognizes two distinct forms: synchronous and asynchronous extensions.” (Constantine & Lockwood, Ltd.) – courtesy of guuui

User Experience in India: State of the Profession 2004

“Overall, the survey reveals the picture of a profession that is rapidly maturing. Many practitioners have more than four years experience. Some institutes are playing a key role in educating students in the field. Practitioners have knowledge of many of the techniques and methods of the field. Practitioners face a number of constraints in their work which seem very similar to those faced by practitioners in other countries and regions. In short, User Experience in India has arrived!” (Uzanto Consulting)

MSN Personas

“We try to understand an audience through numbers, charts and graphs, but often times we lose sight of the people who represent these statistics. The MSN audience is comprised of a broad range of users at different stages in their life, who use MSN in their own unique way. To help better define the people behind the numbers, MSN has created personas for some key audience segments.” (MSN Advertising) – courtesy of brett lider

Xanalogical Structure, Needed Now More than Ever: Parallel Documents, Deep Links to Content, Deep Versioning, and Deep Re-Use

“Xanalogical literary structure is a unique symmetrical connective system for text (and other separable media elements), with two complementary forms of connection that achieve these functions — survivable deep linkage (content links) and recognizable, visible re-use (transclusion). Both of these are easily implemented by a document model using content lists which reference stabilized media.” (Theodor Holm NelsonACM Computing Surveys Hypertext and Hypermedia Symposium)

Understanding visual communication

“They say that a picture is worth a thousand words. Indeed, some pictures are better at conveying some things than words. Still, not all pictures are created equal, and the power of visual communication is sometimes misunderstood, if not misused. Pictures are no panacea; some words may well convey concepts better than a thousand pictures, too.” (Jean-luc Doumont – STC Belgium)

The complexity principle

“Overly complex interfaces significantly impact usability and must be avoided. While there are plenty of studies researching this issue and plenty of data to point to how complexity hurts a product, in order to truly address the root of problem, designers must understand where complexity originates.” (Design by Fire)

Experience Design and the Design of Experience

“(…) we enter the era of what I’m calling Experience Design. A quick scan of our sociocultural landscape suggests that, in terms of artistic practices, mass entertainment, sports, and emerging technologies of pleasure, productive forces are increasingly targeting experience itself – that evanescent flux of sensation and perception that is, in some sense, all we have and all we are.” (Erik Davis – techgnosis) – courtesy of brad lauster

The Risks of Discounted Qualitative Studies

“The discerning usability analyst should employ a mix of both qualitative and quantitative methods when discovering usability problems. The risks of relying heavily on a qualitative approach can lead to a severe misdiagnosis especially when usability problems are difficult to detect. This article is a response to Nielsen’s ‘The Risk of Quantitative Studies’ and shows how the problems voters had with the ‘butterfly-ballot’ in the Florida 2000 election would not have been detected with popular discounted qualitative methods. The problems with relying on one-size-fits all usability guidelines such as ‘testing with only five users’ and the inherent bias of pay-for-hire guru’s are also discussed.” (Jeff Sauro – measuring usability)
