ArUco marker JSON files

Two types of JSON files can be employed when creating VR content that incorporates ArUco markers.
When creating ArUco markers, the marker settings are contained in a JSON file that you can upload to the headset or insert directly into an application's code. The marker settings are then sent to the headset's tracking engine through an API, enabling the headset to identify the ArUco markers in the play area. For details, see the following:

Two types of JSON files are generated when creating ArUco markers:

  • markers_list.json

    The strings included in this file can be implemented independently of code. The JSON file is uploaded to the internal or external headset storage, and the marker settings are applied when the application loads the strings in the JSON file.

    With this method, an application's code doesn't need to be modified for the marker settings to be applied.

  • markers_list_escape.json

    The strings included in this file can be embedded directly into the application's code. The strings are copied and pasted into the code, and the marker settings are applied when the headset loads the application.

    With this method, the headset doesn't need to access a JSON file from internal or external storage to apply marker settings. The marker settings are applied when the headset loads the application.
