Características e medidas de software para avaliação da qualidade da interação humano - computador em sistemas ubíquos

Abstract

Ubiquitous systems change the way users interact with computers, because their services must be everywhere, supporting users in several everyday activities in a transparent way with little or no need for attention or data input from a user. So, an essential element to ensure these systems adoption is to assess their quality. However, the ubiquitous systems specific characteristics, like context-awareness and the new type of interaction, that is the implicit and transparent interaction, suggest taking into account new software measures in these systems’s quality assessment. Thus, the aim of this work is to define software measures to human-computer interaction quality assessment in ubiquitous systems. To achieve this goal, first it is identified essential quality characteristics of ubiquitous systems that impact on user interaction. Such identification is done through a systematic mapping, to collect what has been already defined and evaluated in the literature. After that, the Goal-Question-Metric (GQM) method is used to define the software measures proposed in this work. The set of proposed measures is evaluated through case studies with three ubiquitous applications developed to mobile devices.
