Avaliação da perspectiva do usuário em interfaces tangíveis: um estudo comparativo em sistemas baseados em hardware específico e e sistemas mediados por software

Abstract

The main goal of this work is to evaluate if different ways of constructing systems that use tangible user interfaces (TUIs) interfere in user’s experience. To do so, we propose two systems, one of them makes use of dedicated hardware while the other uses an embedded system with a computer. After the development and adequacy of both proposed systems, we executed user tests, taking into account the usability and user experience (UX). Usability was tested with the intent of assuring that both systems had similar functionalities and, with this aspect in mind, focusing primarily on the UX itself. Besides that, this research presents two systematic literature reviews (RSL) in its theoretical foundation, that were made with different objectives and scopes. One of this reviews was made to explore how systems that use TUI in their input or output are built. This review was done on the beginning of this master’s course and had the goal of limiting the focus of this master thesis. Meanwhile, the second review was done on the last semesters of this master’s course, with the main goal of mapping the relation between two areas, pervasive computing and human computer interaction, focusing specifically on the interfaces used. As a result of the case study, was possible to realize that, considering the user’s point of view, having a dedicated hardware system is better than a system that is based on software.
