Knowing How People Behave on Website
How people interact with screens evolve over time. As new devices are introduced to the market, new ways of interacting become possible. As people master a certain level of complexity, they become ready for the next level. In this way, UI design is a moving target. Each site or app should choose a specific psycho-demographic segment in the technology adoption curve (i.e. early adopter, early majority, late majority, etc..), and optimize the experience for them.
