Exploring how experienced and unexperienced designers use and evaluate a usability-oriented interaction and navigation model

Abstract

Representing quality aspects in models used in the design of interactive systems can support to design solutions with higher quality of use. However, the quality of the designed solutions can be influenced by the designers’ experience and by the models’ expressiveness for representing the quality aspects. Recently, we proposed USINN (USability-oriented INteraction and Navigation model) to express usability mechanisms in interaction and navigation modeling solutions. In this paper, we present an experimental study conducted with students, characterized as experienced and unexperienced designers, in order to investigate how is USINN adopted and evaluated by designers with different levels of experience in the software industry. The results indicated that the quality of artifacts produced by experienced and unexperienced designers was similar. However, the unexperienced designers indicated higher intention to adopt USINN in the software industry.
