Developmental process of interface design evaluations

Abstract

User Centered Design (UCD) Process facilitate the approaching to people in order to determine use and design requirements throughout applying diverse techniques for obtaining qualitative and quantitative information, including social, emotional physical and cognitive user’s characteristics, as long as system interface requirements. User Interface Design (UI), Interaction Design (IxD), Design of Experiences of Use (UX), and the Ergonomic approaches aid design teams clearly define objectives to be met, knowing the level of development they have got in an specific stage of the design process, and ensure during the process goals do not change but instead, evolve according to emerging information that arises from Users interaction. Iterative processes along design enable implementation of formative and summative assessments through the use of prototypes in order to evaluate interactions and allowing the process feedback. As a systemic approach UCD has recursive characteristics which in some stages of its process, like Inquiry and Evaluation, are of paramount importance to adequately accomplish tasks of problematisation and assessment, by diagnosing whole system in which Users are immerse. By giving Users voice during the design process, being either novice or expert Users, Inquiry and Evaluations stages of the UCD process, aids accurately reflecting detailed characteristics the Interface must have, and at which degree Design goals have been reached out.
