This study utilized the application of authentic Virtual Reality (VR) to replicate the real-world complex system scenarios of a large retail supply chain. The proposed VR scenarios were developed based on an established systems thinking instrument that consists of seven dimensions: level of complexity, independence, interaction, change, uncertainty, systems’ worldview, and flexibility. However, in this study, we only developed the VR scenarios for the first dimension, level of complexity, to assess an individual’s Systems Thinking Skills (STS) when he or she engages in a turbulent virtual environment. The main objective of this study was to compare a student’s STS when using traditional ST instruments versus VR scenarios for the complexity dimension. The secondary aim was to investigate the efficacy of VR scenarios utilizing three measurements: Simulation Sickness Questionnaire (SSQ), System Usability Scale (SUS), and Presence Questionnaire (PQ). In addition to the three measures, NASA TLX assessment was also performed to assess the perceived workload with regards to performing the tasks in VR scenarios. The results show students’ preferences in the VR scenarios are not significantly different from their responses obtained using the traditional systems skills instrument. The efficacy measures confirmed that the developed VR scenarios are user friendly and lie in an acceptable region for users. Finally, the overall NASA TLX score suggests that users require 36% perceived work effort to perform the activities in VR scenarios.
Resumo: O presente ensaio faz parte de uma pesquisa sobre narrativas -formas de contar, de dançar, de filmar, de escrever -que se articula a partir de três intuições: os corpos precisam se movimentar, dançar e ocupar espaço; ver alguém dançando contagia; o cinema é uma forma narrativa privilegiada de apresentação dos corpos dançantes e um espaço de contato e ressonância no tocante ao espectador, em diálogo com o pensamento sobre corpo, cinema e escrita do filósofo francês Jean-Luc Nancy. Aqui trata-se de olhar e escutar uma cena do filme Cría Cuervos (1976) do espanhol Carlos Saura.Abstract: This essay is part of a wider research about narratives -ways of storytelling, of dancing, filming, writing -that develops out of three intuitions: bodies must move, dance and occupy space; dancing is contagious; and movies are a privileged narrative form to present dancing bodies and a space of contact and resonance for the spectator, in dialog with the French philosopher Jean-Luc Nancy's thought on bodies, cinema and writing. In this way this text proposes to look and listen to a scene from the 1976 movie Cría Cuervos by Spanish filmmaker Carlos Saura.
