The rising popularity of ubiquitous computing and social networking has changed the way people and businesses use technology. Across all platforms, the differentiator between widely adopted applications and those that are discarded is successfully meeting user needs through a positive experience. User-Centered design techniques provide the tools needed to create that engaging and usable application. Usability testing is needed to find what will trip up your users and stand in the way of your product meeting its goals. Learn how to quickly gather the information you need about the where, when, why, how, and by whom the application will be used as well as the techniques to apply that information to an interface design. Once that design is complete, understand effective ways to organize and execute a usability study to ensure the integrity of the interface design.
