The version of the simulator used for the article: Strangers in a Strange Land: New Experimental System for Understanding Driving Culture Using VR can be found under the main-OculusCV1 branch.
Updated version of CrossCulturalDriving including ECS, new networking stack(MLAPI), Unity.InputSystem, and Unity XR Interaction Toolkit with Oculus Plugin alongside Oculus Integration, works with Logitech G29 steering wheel. The visual scene is rendered on the standalone headsets. They connect wirelessly to the server which manages the scenario progression, questionnaire and data logging.
These notes concern the simulator in development and are subject to change. The standard operating procedure is documented on Google Docs/Overleaf. Ask Hauke Sandhaus or David Goeddicke for access.
Git:
Once you pulled the repository you need to initialize the submodule ReRun:
git submodule update --init --recursive
Unity: import the necessary third party packages: Ultimate Replay Runtime File Browser
The individual scenarios need to contain the ScenarioManager prefab. SpawnPoints denote the starting positions of the participants. Trigger Boxes are the end zones of the scenario and start of the questionnaire. RoadNetworks can be built with theEasyRoads3D assets. The networked traffic light prefab will change the status for all participants at once. Scenes need to be included in the build and included in the Connection and Spawning script (inside Network Manager on the GameManagment Scene)
Releases can be found in https://github.com/FAR-Lab/CrossCulturalDriving/releases. Install these to the oculus headset through the oculus developer hub. Run the server from the executable file in the zipped folder.
The servers local IP is set in the participants VR-UI. Ensure that no firewall is blocking local network access.

The participant has to look straight ahead when the calibration button on the server is pressed. During the calibration, which lasts a few seconds, both hands should be placed on the top of the steering wheel.
The blinkers are located behind the steering wheel left and right. The questionnaire can be clicked with the round steering wheel button and head pose. The traffic lights are controlled through the interface on the server.
Rerun .replay files are automatically stored on the server path: C:\Users\<USERNAME>\AppData\LocalLow\<USERNAME>\XCDriving\test
Currently the project is not licensed for use. The scenes use assets from the Unity Asset Store under the standard license.
