user interface design principles in software engineering

User interface is the front-end application view to which user interacts in order to use the software. The design of the user interfaces is a sub-task of the design phase. Will the user be sitting, standing, or performing other tasks unrelated to the interface? Structure: Design should organize the user interface purposefully, in the meaningful and usual based on precise, 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. Interface Design Principles - The design of the WebApp and its interface should optimize the user's work efficiency, not the efficiency of the Web engineer who designs and builds it or the client-server … 1. Streamline interaction as skill level advances and allow the interaction to be customized: Advanced or highly skilled user should be provided a chance to customize the interface as user wants which allows different interaction mechanisms so that user doesn’t feel bored while using the same interaction mechanism. As software and technologies evolve at a dazzling pace, it is very difficult to extract precise information and establish new trends of thought. Relies heavily on recall rather than recognition. Feedback: The design should keep users informed of actions or interpretation, changes of state or condition, and bugs or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to users.
