“Computers and users process information in distinct ways — so do individual users. Although it’s relatively easy to get a computer to understand input, what with fixed standards and universal APIs, usability with human users is not absolute. User interface usability is relative to the experience level of individual users. UI designer Mike Padilla provides an overview of UI design for Web-based productivity software with a focus on the broadest range of users, examining what makes an application UI usable and detailing concepts that can facilitate an efficient, broad-based UI design.” (Mike Padilla – IBM developerWorks) – courtesy of webword
