An Innovative Approach to User Interface Engineering

Abstract

If a computational system is to be successful, it must have an impressive user interface endowed with appealing usability features for providing exceptional user experience. User interface engineering requires an innovative approach because it is one of the most challenging areas given the diversity of knowledge, ideas, skills and creativity needed for building smart interfaces in order to succeed in today’s rapidly paced and tough, competitive marketplace.Modern engineering aspects including analytical, intuitive, user experience, artistic, technical, graphical, mathematical, psychological and programming models need to be considered in the development process of a user interface. This paper critically examines some of the past practices and recommends a set of principles for designing alluring user interfaces.It also demonstrates how UML use case diagrams can be improved by naturally relating use cases to user interface elements. The improved design constructs of an enhanced UML view are presented with examples for highlighting and clarifying important user interface engineering issues.
