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.

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.

Sketching User Experiences (1)- Bill Buxton

In "Interacting with Paper," Bill Buxton proposes paper prototyping which he calls 'paper interfaces' as an alternative and a better solution to testing user experiences before starting the design process. The author suggests that paper holds powerful affordances that represent systems of control that users respond to and experience, both in terms of a sketch's control over users' actions (control commands) as well as its faculty to lead users to focus on the 'experience' and 'usability' of an interface rather than on its aesthetic feel or design.

Oliver Sacks on Visual Hallucinations

“An Interview with Don Norman.” – Howard Rheingold

Norman stressed the importance of understanding the logic behind the act of designing, which includes considerations for the human factor. In this interview he sets ground rules for 'good design' and focuses on the idea that design should be inherently 'humane'; which is to say that technological tools need to be thought of with a user-centered approach. "Cultivate Sensitivity to Design" explains how experimenting (observing, testing, etc.) helps designers reach a place of "empathy" for the user and simplifies complex products or systems in accordance to audience feedback.

“Evaluating Usability Throughout Design and Development” – Joseph Dumas & Janice Redish

Joseph Dumas & Janice Redish analyze the potential benefits of combining various evaluation methods as complementary tools for usability testing in the context of usability engineering.
