The focus of this article is on the application of Human Factors and Ergonomics (HFE) principles on design process. Designers begin acquiring HFE principles and data during their university education. Universal Design (UD) approaches HFE as incorporating the whole of the population rather than a certain percent. This study explores the effectiveness of a specially designed course on UD in an interior architecture undergraduate program. After completion of the course, students were asked to evaluate their learning process. It was observed that learning UD principles is a process and requires some time, rather than being book information. The majority found the course helpful in increasing their awareness of UD issues. They also found the course helpful for improving their design work. The research suggests UD to be integrated into the interior design curriculum both as a separate course on its own and within the context of the design studios.
