Avaliação heurística e teste de usabilidade para softwares de design de interiores

Abstract

An interior designer is the professional responsible for creating and modifying any internal space by planning and executing a project. To assist his work, this professional uses software known as Computer-Aided Design (CAD), which have the ability to create and display an environment through two-dimensional or three-dimensional projections. Many of these programs may have problems in their interfaces, turning it difficult or impossible for users to use them. Thus, it is necessary arises to carry out an evaluation capable of identifying and classifying these problems. The present work apply two usability evaluations, a heuristic and a usability test. The first is based on the heuristics proposed by Nielsen, originally specific to Web applications, that were adapted in this work to the context of interior design. The second uses the System Usability Scale - SUS model. To prove the importance of these evaluations, they were applied to real software. The results allowed to classify the interface software of the evaluated program. With a heuristic evaluation it was possible to determinated specifics errors. With the usability test was determined and classified all the problems found, categorizing the system in general.
