A proposal of an evaluation model under the principles of universal design

Abstract

The aim of this work is to try to set out how the Universal Design (UD) paradigm can influence the process of product design and how the models of evaluation should work for products designed for all users. Firstly, we will give a short introduction of some of the basic models that try to explain the product design and development process emphasizing, especially, the role given to evaluation of the design stage. Secondly, what we would like to do is explain, on one hand, the paradigms of Human Centred Product Planning and Design and, on the other hand, UD/Inclusive Design (ID)/ Design for All (DfA) in order to clarify the bonds and relationships which are established between these in the field of Ergonomics and Human Factors. In this context, we explain how these philosophies have an effect and an influence in the process of design, especially in the interstages of evaluation. Finally, we present a model that proposes the integration of UD principles into the process of design applying it to the case of a wheelchair.
