Laws of UX Design

The laws of UX design based on user behavior psychology are examined, which designers can apply in practice. The laws of Jacob (about familiar interfaces), Fitts (about the time to reach a goal), Hick (about the time needed to make a decision), Miller (about the user's short-term memory), Postel (about the balance of conservative and liberal), Tesler (about the complexity of the system), and the von Restorff effect (about the most memorable object) are described. The "peak-end rule" related to the peculiarities of judgment formation is also discussed. The effect of perceiving aesthetically pleasing design as the most user-friendly is considered. The second edition pays special attention to the application of artificial intelligence for creating intuitive, human-centered products and services, and the number of visual examples has been increased.
