A falta de um documento genérico que apoie no processo de avaliação UX para realidade
virtual e aumentada torna mais complicada essas mesmas avaliações, visto que por vezes
podem ser esquecidos pormenores essenciais para o seu sucesso.
Nesta dissertação é proposto um protocolo genérico, criado através da observação de
testes, feedback de investigadores, analise de livros e documentos de investigação
relevantes, que auxilie no processo de avaliação UX para AR e VR. Este protocolo segue
quatro fases diferentes, sendo a primeira a fase de planeamento, seguindo-se pela fase de
testes piloto, sessão de testes e finalmente a análise dos resultados.
O protocolo recomenda a utilização de alguns documentos tipo e tabelas auxiliares.
Nomeadamente, um guião modelo, uma entrevista e questionário tipo, uma checklist de
pormenores a não esquecer numa sessão de avaliação e diretrizes para avaliação UX a
seguir para uma sessão de avaliação bem-sucedida. Contém ainda material necessário para
verificar que métricas usar e como as usar, fazendo ainda recurso a tabelas auxiliares de
analise estatística.
Este protocolo foi validado através de um questionário feito a investigadores que
trabalham no Laboratório JLF (João Lourenço Fernandes) do IST, de onde se conclui que o
mesmo é útil, claro e genérico o suficiente para ser aplicado em diferentes contextos de AR
e VR, e que apesar de poder usufruir de algumas melhorias no futuro, já pode ser utilizado
como documento de apoio para avaliação UX para AR e VR.
The lack of a generic document to give support to UX evaluation for AR and VR makes it difficult to apply those same evaluations, since sometimes essential details for its success end up being forgotten. Due to this, a generic protocol was created through test observation, investigator feedback, books, other documents and papers analysis, and is proposed to help on UX evaluation in AR and VR. This protocol has four different phases, being the first one the Planning, followed by the Pilot tests phase, Test session phase and finally the Results analysis. Its recommended the use of some standard and model documents and auxiliary tables, such as model script, standard interview and questionnaire, a checklist with some “not to forget” details before an evaluation session, US evaluation guidelines to follow for a successful evaluation session and material related to metrics and statistics explaining how to use them. This document was validated through a questionnaire for researchers working at JLF (João Lourenço Fernandes) Laboratory from IST Tagus Park, from which its concluded that the protocol is useful, clear and generic enough to be applied in different AR and VR contexts and that although in can have some future improvements, its already usable as a supporting document for UX evaluation for AR and VR.
