subject: Usability Terms Explained: Learnability and Its Significance for User Interface Design – Part I [print this page] Beyond the expectation of familiarity in an interface design, extra attention needs to be paid to maintaining consistency. Although familiarity itself also calls for consistency, consistency must also be maintained within the different parts of a software application's interface design. Your application has to react in the same way throughout. An example of this is with the login process. The login and sign up buttons should be consistently displayed throughout your website's interface design i.e. if it is found on the top right corner then so should it remain throughout. Consistency becomes more of a challenge with applications that allow users to change skins or customize the interface design. A skin that requires users to relearn how to use an interface design is likely to turn off users.
