“…The prototype of the VO system in Howie and Gilardi (2019) was originally intended for observation of pre-defined training simulations, which only required the knowledge of the VR user to operate (Howie and Gilardi 2019). In this paper, we present an extended version of VO that includes a 'Full Simulation Capture' method of recording external actions of other non-player controlled objects.…”

“…This paper builds upon Howie and Gilardi's 'Virtual Observation' system described in Howie and Gilardi (2019). Howie and Gilardi (2019) system records and reconstructs virtual actions of users in a simulation, allowing researchers and developers to virtually observe users in a VR simulation. The term 'Virtual Observation' (VO) is used as observers are not observing the user directly, but instead they observe the input, movements and actions conducted by the user within the simulation.…”

“…Collected input and movement data is used to recreate the user experience in the simulation with synced actions and approximate movement. In Howie and Gilardi (2019), VO was validated in a detailed simulation environment for fire safety which tasked the participant to correctly identify and extinguish fires in a VR training simulation (Howie and Gilardi 2019) (Fig. 1).…”

“…1). VO was used for reconstructing users movement and actions for review after-action, meaning the observation was conducted after the user had completed the simulation (Howie and Gilardi 2019). The VO system in Howie and Gilardi (2019) can reconstruct VR simulations for a wide range of use cases (Wobbrock and Kientz 2016).…”

In this paper, we present 'Virtual Observation' (VO) a software tool for contextual observation and assessment of user's directly from within the virtual reality (VR) simulation framework. Unlike other recording systems, the VO system described in this paper focuses on recording and reconstructing VR user's positional, rotational and input data to recreate the same experience the user had with a VR simulation. Different from animation-based approaches, VO records user inputs and reconstructs the simulation from them and the user positional data. Moreover, the system allows the broadcast of this information to a remote machine enabling remote live observation of the simulation. Datasets recorded by the system can be shared by exporting them as XML files or, optionally, into a standalone online application, such as browser WebGL, allowing researchers, developers and educators to share and review a VR user simulation through a free-moving camera using a web browser. In this paper, the consistency of the data generated from the software by the client, server and reconstructed datasets acquired during real-time live observations was evaluated. We conclude that this Virtual Observation software offers detailed reconstruction of low-level information and visual information of user actions during simulations for both live and offline observations. We envision that our system will be of benefit for researchers, developers and educators that work with VR applications.
