In this paper we present 'Virtual Observation' (VO) a software tool for contextual observation and assessment of users from within the same Virtual Reality (VR) simulation as the user. Unlike other recording systems, the VO system described in this paper focuses on recording and reconstructing VR users positional, rotational and input data to recreate the same experience the user had with a VR simulation. Moreover, the system allows the broadcast of this information to a remote machine allowing remote live observation of the simulation using default networking architecture. Datasets recorded by the system can be shared by exporting them as XML les 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 others detailed reconstruction of low-level information and visual information of user actions during simulations for both live and oine observations. We envision that our system will be of benet for researchers, developers and educators that work with VR applications.
