Methodologies and Evaluation Tools Used in Tangible User Interfaces

Abstract

Tangible User Interfaces (TUI) have been a recurring field of investigations of Human Computer Interaction (HCI) area because they stimulate the process of collaborative interaction, for example, in addition to the ability to give physical forms to digital information, to understand and manipulate physical and material objects. Considering the specific characteristics of TUI, this study analyzes whether the evaluation methods used previously correspond in the same way in this context. Therefore, the goal of this paper is to present results of the analysis of 50 articles that use methodology and/or evaluation tools used in TUI of the last 5 years. Through the Systematic Literature Review (SLR) methodology, it is possible to identify the evaluation approaches used, the instruments and the genres of these applications. From this, the state of the art was defined on the evaluation processes of TUI, contributing to the information base for proposing new evaluation methodologies that respect the particularities of the tangible interaction.
