Design de heurísticas para avaliação de sistemas de realidade virtual semi-imersiva

Abstract

This thesis presents the process of creating new heuristics to evaluate semi-immersive reality applications. Is inserted in the context of interaction design, specifically in the part of user experience design - UX (user experience design) with the use of this knowledge focused on semi-immersive, or non-immersive, Virtual Reality (VR) called desktop virtual reality. The focus of the research is the usability of these interfaces, specifically the evaluation of how to perceive their use. For this, heuristic assessments and domain-specific heuristics are addressed for semi-immersive applications for educational purposes. After extensive bibliographic research, there was a lack of existing heuristics for the semi-immersive VR domain, as well as few, for VR in general, thus constituting our research problem. Starting from the research problem, we find in the Design Science Resource (DSR), the appropriate research methodology to structure, organize and guide this work. Following the steps of the DSR, we sought the methods and techniques for generating heuristics, an artifact selected to solve the problem raised, and based on others methodologies, we developed a method composed of 8 stages. Thus we developed and proposed a set of usability heuristics for educational semi-imersiva VR applications, based on information and usability problems found in more than 60 articles, researched in the bibliographic review. These heuristics were tested and validated by specialists, also using a control list, with heuristics for VR in general, following the instructions of the methodology that we proposed. After statistical analyses the results indicate that the proposed heuristics performed better than those of the control list, both in the number of errors found and in the specificity and quality of these errors, addressing aspects that are not covered by the control heuristics and that help to design better applications in the domain of semi-imersiva VR.
