Learnabilty

Learnabilty
The ease and speed in which an audience learns how navigate in a user interface or system (Foraker Design, 2005). The degree of learnability depends on the familiarity, consistency, generalizability, predictability, and simplicity of the interface (Louis, 2007). Learnability is important because people generally prefer to learn a system quickly and be able to carry out their tasks without too much tediousness (Preece, 2007). A main concern is how much time a person is willing to spend on learning a system. It is unnecessary to develop additional functionalities if the majority of people are unwilling to learn it (Preece, 2007).
