Kuniavsky’s “Information Shadows”

Information shadows enable users to access information about their products and experience them in very different ways than could have been imaginable before the Internet. Today, products mean so much more to people and impact their product/customer experiences in new ways. With built-in ubicomp, customers experience products that have a much wider network of associations.

How to Plan, Design, and Conduct Effective Tests – Jeffrey Rubin & Dana Chisnell

Testing has two main objectives: on the marketing level, it aims at improving sales; on a user-centered level, it aims at minimizing user frustrations and maximizing a product's usability. As the authors point out, testing goals inform the design of a product; those work in terms of the usefulness or relevance, learnability, efficiency, effectiveness, and satisfaction factors.

“Defining Goals and Concerns” and “Deciding Who Should Be Participants” – Joseph Dumas & Janice Redish

Before you begin testing it is important to set your primary evaluation goals and concerns. Once those have been defined, it will be possible to plan a usability test accordingly. Dumas & Redish raise the following processes: making choices among goals and concerns; moving from general concerns to specific ones; and understanding sources of goals and concerns.

Designer/Artist + Co-Creation

With the advent of new technologies and the rapid dissemination and accessibility of information, artists and designers develop increasingly sophisticated ways of thinking about the world in visual forms and of approaching open-ended questions or specific problems in new and exciting ways. It seems that design and art now represent blurred categorizations: artists and designers grow more apt at interchanging roles and are increasingly willing to collaborate and co-create.

An Introduction to Usability – Patrick Jordan

Based on the International Standards Organisation's categories of "effectiveness, efficiency and satisfaction," the author determines ways in which usability can be quantified. 'Effectiveness' is the capacity for a product to generate (or enable) output; 'Efficiency' is measured as the level of effort invested in completing an action or task (for example, the author categorizes usability errors as distinguished between a 'slip' and a 'mistake' in user performance and experience. For him, a slip is when a user accidentally performs the wrong action which is readily corrected by the user, whereas a mistake is when a user thinks he is doing the right thing (intuitive action), but is unable to perform his task.

An Introduction to Usability (continued…) – Patrick Jordan

Designing for usability is a user-centered approach to design. Jordan lays out the different considerations to keep in mind during the design process and proposes a set of methods (some empirical, others non-empirical) that can be used as testing tools and discusses the advantages and disadvantages that come with each method. His writing allows designers to understand better that there are different ways of testing users and that some styles are more appropriate depending on the content of tasks involved in using a given product or interface and its relation to a demographic/technographic target audience.
