Interaction design of public electronics equipment: Approach to categorization systems and analysis model

Abstract

Technological development has changed the way users relate to products, they are no longer passive receivers of functions to interact with increasingly complex systems. This research addresses the problem of consumer interaction with public electronic technology products. There are several studies dealing with the disciplines that study the interaction between the user and the electronic product (Preece, 2005; Johnson-Laird, 1983; Helander, 1997, Sutcliffe, 1995; Norman, 1990; Moraes, 2001), making it possible to obtain knowledge about human beings, technology and the way they operate. This research aims to identify the areas of interaction design that involve the human-machine system, in particular the disciplines that contribute to good usability. Six typologies are proposed that describe specific interface characteristics studied according to the model of complexity defined by Gomes Filho (2003). Exploratory research in Portugal identified twenty-six interactive systems. To characterize the public electronic systems, the study presents a structured analysis of the variables mentioned previously, in relation to both reliability and validity, as well as functionality. The results are compared with the literature and the implications discussed for the design of the User Interface System Model.DOI: http://dx.doi.org/10.4995/IFDP.2016.3287
