Is there benefit in asking the user to authorise my app with their social networks? Does my app protect the user’s sensitive information with sufficient care?

Foursquare does a sterling job of explaining context. This screen alone explains the social context (friends who liked a venue), location context (map & distance), and time context (“This place is busier than usual”) that has underpinned these recommendations.

Work User-Centered Design (UCD) is the process of designing a tool, such as a website’s or application’s user interface, from the perspective of how it will be understood and used by a human user. Rather than requiring users to adapt their attitudes and behaviors in order to learn and use a system, a system can be designed to support its intended users’ existing beliefs, attitudes, and behaviors as they relate to the tasks that the system is being designed to support. ■ The result of employing UCD to a system design is a product that offers a more efficient, satisfying, and user-friendly experience for the user, which is likely to increase sales and customer loyalty.

Practice During a usability test, mimic the real world as much as possible. Recruit representative users and ensure that each task scenario: 1) is realistic and typical for how people actually use the system, when they are on their own time, doing their own activities; 2) encourages users to interact with the interface; and 3) doesn’t give away the answer.

Utility value ■ Utility value refers to the utilitarian consequences of a product, for example the fact that it might enable the accomplishment of a physical or cognitive task. It encompasses the values of convenience, economy, and quality as sub-categories. ■ In practice, convenience is defined in various ways that include concepts such as accessibility, appropriateness, avoidance of unpleasantness, or compatibility to the local context rather than just as a matter of saving time and effort. ■ For example, rather than as a means for economizing time, Turkish women use a refrigerator as a tool for reordering and managing time. They use it for storing elaborate homemade dishes in semi-prepared form or extra homemade pastries for later use.
