UI Design Principles to help newcomers. The User Interface (UI) is a critical part of any software product. When it’s done well, users don’t even notice it. When it’s done poorly, users can’t get past it to efficiently use a product. To increase the chances of success when creating user interfaces,
most designers follow interface design principles. Interface design principles represent high-level concepts that are used to guide software design. UI Design Principles to help newcomers
The User Interface Principles are :-
The structure principle: Design should organize the user interface purposefully, in meaningful and useful ways based on clear, consistent models that are apparent and recognizable to users, putting related things together and separating unrelated things, differentiating dissimilar things and making similar things resemble one another. The structure principle is concerned with overall user interface architecture.
The simplicity principle: The design should make simple, common tasks easy, communicating clearly and simply in the user’s own language, and providing good shortcuts that are meaningfully related to longer procedures.
The visibility principle: The design should make all needed options and materials for a given task visible without distracting the user with extraneous or redundant information. Good designs don’t overwhelm users with alternatives or confuse with unneeded information.

The feedback principle: The design should keep users informed of actions or interpretations, changes of state or condition, and errors or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to users.
The tolerance principle: The design should be flexible and tolerant, reducing the cost of mistakes and misuse by allowing undoing and redoing, while also preventing errors wherever possible by tolerating varied inputs and sequences and by interpreting all reasonable actions reasonable.
The reuse principle: The design should reuse internal and external components and behaviors, maintaining consistency with purpose rather than merely arbitrary consistency, thus reducing the need for users to rethink and remember.
According to Jef Raskin (an American human-Computer Interface expert best known for conceiving and starting the Macintosh project at Apple in the late 1970s) there are two laws of user interface design:-
First Law: A computer shall not harm your work or, through inactivity, allow your work to come to harm.
Second Law: A computer shall not waste your time or require you to do more work than is strictly necessary. UI Design Principles to help newcomers
Additionally he mentions that “users should set the pace of an interaction”, meaning that a user should not be kept waiting unnecessarily and that an interface should be monotonous with no surprises “the principle of monotony
