User Interface Design for Disabled People Under the Influence of Time, Efficiency and Costs

Abstract

Applications being designed for disabled people so far are showing three main issues: specific target user group, specialized user interface (UI) and interdependence problem. In addition, three essential criteria do also affect the application's usability, namely time, efficiency and costs. In order to overcome these problems, we propose a different perspective of User-Centered Design (UCD) by dividing and analyzing the UI architecture design process over three interdependent spaces: User, Need and application. Finally we provide the reader with an algorithmic guideline towards minimizing the interdependence issue between interaction modalities. © Springer International Publishing Switzerland 2014.
