Many characteristics of a product are evaluated during the development phase, such as function, aesthetics and manufacturing. The conception phase is supported by drawings and computer graphics, followed by physical prototypes that help evaluating the product features. The augmented reality technology has a great potential to assist the designers in this phase, reducing the development process time and costs and improving the quality of the evaluation. This paper presents a study that intends to investigate the suitability of using augmented reality to evaluate the usability of electronic products.
Este artigo apresenta uma revisão bibliográfica dos principais métodos de avaliação de usabilidade aplicáveis a produtos industriais. Inicialmente é apresentado o conceito de usabilidade e em seguida, são discutidos os métodos de avaliação de usabilidade de produtos: os que se baseiam nos usuários e os que se baseiam na avaliação de especialistas. Por fim é apresentada uma sistemática para a seleção dos métodos de usabilidade, que está sendo aplicado em um projeto de pesquisa em andamento com foco na avaliação da usabilidade de produtos eletro-eletrônicos com o auxílio da tecnologia de realidade aumentada.
Developing an usability test involves defining the metrics that are being evaluated, the methods used and the right tasks to be performed to achieve the objectives from the usability test. This article presents the development of an usability test aimed to evaluate the experience while first interacting with a product by using the augmented reality technology. This usability test is part of a bigger research that aims to evaluate if the use of augmented reality helps the process of learning how to use a new product. The paper starts with a literature review of related works, explaining many of the tools developed for evaluating usability tests. This section is followed by a methodological explain and the description of the developed usability test itself. The conclusion presents suggestions of further improvements.
This paper explores the importance of researching the intuitiveness in the product use. It approaches the intuitiveness influence for users that already had a visual experience of the product. Finally, it is suggested the use of a table that relates the tasks performed while using a product, the features for an intuitive use and the performance metric "task success".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
