Rerun: Enabling Multi-Perspective Analysis of Driving Interaction in VR

Rerun is a software system to support post-facto analysis of driving simulation research. It is built in Unity 3D, and captures virtual driving behavior so that it can be played back. A unique feature of Rerun is that the playback can be rendered from any perspective in the virtual space. This is useful in multi-person interaction studies because researchers can examine scenarios from each participant’s perspective, or even from an outside observer’s perspective. This enables fine-grained understanding of implicit and explicit signalling between participants, enabling research to reconstruct what factors are pertinent to driving communication.
