Conferência internacional realizada em Coimbra, Portugal, de 26–29 de junho de 2017.Virtual worlds are widely regarded as a successful approach for professional team training, due to promoting collaboration through user avatars. Current theoretical models of Computer-Supported Cooperative Work (CSCW) do not account for the specificity of virtual worlds’ affordances for collaboration, particularly regarding non-verbal communication affordances, which led Cruz et al. to propose in iLRN in 2015 a specific protocol to collect data to support the empirical-grounded refinement of the theoretical treatment of virtual worlds in CSCW. Here, we present the results of applying this protocol to a case study in the training of aircraft maintenance practices. A training simulator platform was built with the Open Simulator platform for this purpose. Through activity observation, collected data provided a set of chains of evidence as proof elements, increasing the amount of empirical data available for future theory development.engVirtual environmentsVirtual worldsCollaborationPresenceNon-verbal communicationAircraft maintenanceconference object2017-06-0910.1007/978-3-319-60633-0_3
